2023.06.07 11:20 Netherlab Programming ESP8266 (ESP-01 module), but it's returning gobbledygook afterwards
![]() | So I am using the esptool.py program to write the firmware to my ESP-01 module. I identified it has a 1MB flash size: submitted by Netherlab to esp8266 [link] [comments] Flash size = 1MB ...so I am using the corresponding firmware with Flash size 8Mbit (512KB+512KB), (firmware was found here: https://github.com/Edragon/esp_firmware/blob/masteFirmware/AT-espressif/NonOS/V1.7.4-ESP8266_NonOS_AT_Bin_V1.7.4.zip): Memory locations So I use the corresponding command to flash the memory: Using esptool.py to write the binary files to the flash When I pull the GPIO-0 pin back to Vcc, reset the module with the CH_PD pin pulled low and then to Vcc again, you can see the module's blue LED go absolutely apesh%*. The output of the Arduino serial monitor is the following endless jargon: Arduino serial monitor I have tried multiple other binary files, some at least don't go apes$@% and just prints gobbledygook once. Still no response when I use the AT commands such as AT+GMR. More possibly useful info: I am using an FT232R to write the binary files. I bought the module on AliExpress (do they supply duds?) I never supplied it with the 5V which so famously would fry it. The FT232R's jumper is set to 3V. I also checked all the voltages with my oscilloscope and they run at 3.3V. I am currently powering it with the Vcc from the FT232R (does it need more current?), but I did use a separate power supply and that didn't work, quite an old adaptor but it can supply 1000mA. Any help would be much appreciated! |

The scheme has the advantages of low cost, low investment and simple installation and wiring, which is beneficial to the further popularization and application of low voltage intelligent distribution. 关键词:开口式电流互感器;低压配电系统;改造项目;工作原理;应用;施工细节 Keywords: Split core current transformer; Low Voltage Distribution System; Renovation Project; Principle; Application; Construction Details
At present, most of the low voltage current transformers in the market are mainly used in the construction of new projects. Due to the rapid development of economy, the awareness of energy saving and emission reduction is gradually improved. The electrical characteristics of many enterprises are: 1)电气柜运行的时间长; 2)大部分电流互感器只是对系统电流进行测量,也没有相应的计量装置和保护装置,计量装置只有一块供电局的总表,而对所有车间电能无法进行考核,系统线路保护装置根本没有; 3)大部分线路干线为大规格铜排,拆卸需要大量的人力和时间,安装常规电流互感器不方便; 4)企业生产时间比较紧迫,不能长时间停电。 所以如需对上述电气进行改造,采用开口式电流互感器可以为用户节约大量的投资。 1)Long running time of electric gas cabinet; 2)Most of the current transformers only measure the current of the system, and there is no corresponding metering device and protection device. The measuring device has only one master table of the power supply bureau, but the electric energy of all workshops can not be assessed, and the system line protection device is not available at all,; 3)Most of the main lines are large size copper bar, it takes a lot of manpower and time to disassemble, it is not convenient to install conventional current transformer; 4)Enterprise production time is more urgent, can not long time blackout. Therefore, the use of split core current transformer can save a lot of investment for users. 2.产品设计Product design 1)结构特点 Structural characteristics 我司开口互感器型号齐全,有线缆专用的圆孔互感器,有适用于铜排的方孔互感器,本产品外壳材料采用PC/ABS合金,具有耐高温、机械强度高、环保等特点;铁芯采用有取向冷扎硅钢片,具有性能稳定,机械强度高,导磁率极高等特点;具体结构如图1所示。 Our company has a complete range of split core current transformer models, including round hole transformers for cables, and square hole transformers for copper bars., this product shell material is PC/ABS alloy, with high temperature resistance, high mechanical strength, environmental protection and other characteristics; The core adopts oriented cold bonded silicon steel sheet with stable performance, high mechanical strength and high magnetic conductivity. https://preview.redd.it/za37feyxdj4b1.png?width=554&format=png&auto=webp&s=9a3996036690916334f88a4f5a225cafdb567fdd 图1(方孔型,适用于铜排) Figure.1 骨架线圈,2-透明翻盖,3-安装螺母,4-接线端子,5-铁芯,6-弹簧,7-外壳,8-安装螺钉。 1-Skeleton coil ,2-transparent flip ,3-mount nut ,4-wiring terminal ,5-core ,6-spring ,7-shell ,8-mount screw. 2)开口电流互感器工作原理Working principle of open current transformer 开口低压电流互感器的工作原理如图1所示,开口电流互感器的一次绕组串联在被测线路中,I1为线路电流即电流互感器的一次电流,N1为电流互感器的一次匝数,I2电流互感器二次电流(通常为5A、1A),N2为电流互感器的二次匝数,Z2e为二次回路设备及连接导线阻抗。当一次电流从电流互感器P1端流进,P2端出,在二次Z2e接通的情况下,由电磁感应原理,电流互感器二次绕组有电流I2从S1流过,经Z2e至S2,形成闭合回路。由此可得电流在理想状态下I1×N1=I2×N2,所以有I1/I2=N1/N2=K,K为电流互感器的变比。但是由于开口式电流互感器的铁芯切开后,使铁芯的性能下将的比较厉害,所以必须将互感器的铁芯截面积加大,而且提高安匝数,将I1×N1=I2×N2≥100AN。 The working principle of the low voltage split core current transformer is shown in figure 1, The primary winding of the split core current transformer is connected in series in the line under test, I1 is the primary current of the current transformer, N1 is the primary turn of the current transformer, I2 current transformer secondary current (usually 5 A、1A), N2 is the secondary turns of the current transformer, Z2e for secondary circuit equipment and connection wire impedance. As the primary current flows through the P1 end of the current transformer, P2 out, If the secondary Z2e is connected, Based on electromagnetic induction, The secondary winding of the current transformer has current I2 flowing through the S1, Z2e to S2, Form a closed loop. Hence the I1×N1=I2×N2, of current in ideal state And so there's I1/I2=N1/N2=K, K is the ratio of current transformer. But since the core of the open current transformer is cut, Make the core performance will be more powerful, So the cross section of the transformer core must be increased, And increase the number of turns, I1×N1=I2×N2≥100 AN. https://preview.redd.it/9720q4fzdj4b1.png?width=554&format=png&auto=webp&s=ab40d65d80aca85338c2ea50eeaa4135b9330b9d 图2 Figure.2 注:图2中1-开口电流互感器的上体,2-开口电流互感器的下体,3-安装螺丝、螺母。 Note: Figure 2- Upper body of the 1- Open current transformer ,2- Lower body of the 2- Open current transformer ,3- Install screws, nuts 3)产品安装Product installation 如图2所示,将互感器的安装螺丝、螺母打开,卸下互感器的下体,将互感器的上体装入配电系统的一次母排,合上互感器的下体,将互感器的安装螺丝穿过互感器上、下体的固定孔,拧上螺母,将互感器的上、下体固定在一起,然后将互感器通过互感器两侧的安装固定孔将互感器固定在母排上,完成互感器的安装。然后将互感器的二次接到测量装置。整个过程比较快速简单。 As shown in figure 2, the installation screws and nuts of the transformer are opened, the lower body of the transformer is unloaded, the upper body of the transformer is loaded into the primary bus row of the distribution system, the lower body of the transformer is closed, the installation screw of the transformer passes through the fixed hole of the upper and lower body of the transformer, the nut is screwed, the upper and lower body of the transformer is fixed together, and then the transformer is fixed on the bus row through the installation fixing hole on both sides of the transformer to complete the installation of the transformer. Then connect the secondary of the transformer to the measuring device. The whole process is relatively fast and simple. 3.应用 Applications 开口电流互感器主要应用在低压配电改造项目中,开口式电流互感器同常规闭口互感器一样输出为标准的5A或1A,测量精度高,容量大,可与测量仪器、仪表配套使用,部分产品过载能力强可与装置配套使用。 Split core current transformer is mainly used in the low voltage distribution transformation project. Split core current transformer is output as standard 5 A or 1 A, as the conventional closed current transformer. The measuring precision is high and the capacity is large. 越南美的工厂为例如图3所示,每条线均需测量三相电流,将采集的电流信号供给电能表DTSD1352,组网之后数据传输到美的工业云系统。A相、B相、C相的可以选择我们的圆孔型开口互感器,每相额定电流为400A,采用AKH-0.66/K K-∮36 400/5开口电流互感器采集电流信号。现场无需拆线或者铜排。 For example, as shown in figure 3, each line needs to measure three-phase current, supply the collected current signal to the watt-hour meter DTSD1352, transmit the data to the industrial cloud system of the United States after networking. A phase, B phase, C phase can choose our round hole type open transformer, each phase rated current is 400 A, adopt AKH-0.66/K K-∮36 The 400/5 split core current transformer collects current signals.There is no need to remove wires or copper bars on site. https://preview.redd.it/f760n2rdij4b1.png?width=588&format=png&auto=webp&s=93dfff1536f6b5044d31870e611f9d4758fe04b2 图3 Figure.3 4.结束语Summary 开口式电流互感器已经成熟的在多个国家工矿企业工程配电监控系统中得到应用,降低了投资成本,提供工作效率及减轻工作难度。 Split core current transformer has been used in the engineering distribution monitoring system of industrial and mining enterprises in many countries, which reduces the investment cost, provides the working efficiency and reduces the working difficulty. 参考文献 Bibliography 1.Solutions For Enterprise Micro-grid System 2020.02 |

Therefore, routine lubrication is usually needed to guarantee the regular procedure of the pet feed pellet making device. submitted by richi-carmen to pelletmachinery [link] [comments] When oiling feed machinery, fowl feed handling equipment manufacturers generally consist of a number of different lubrication states, which can be separated into border rubbing, completely dry rubbing and also liquid rubbing. Typically speaking, oiling the friction parts of tools can properly decrease friction, greatly decrease tools wear and also performance intake, boost devices operating efficiency, as well as extend equipment life. As one of the major ways to enhance devices efficiency, lubrication modern technology has ended up being a common problem in related areas. https://preview.redd.it/pc0kkvw9ej4b1.jpg?width=1200&format=pjpg&auto=webp&s=e17351b53251bbde591fc9485a0d7169e6a4638d Chicken feed handling machine makers require to take note that in the process of lubrication, they must not be thoughtlessly executed, but need to formulate a lubrication management plan in accordance with the development of the business according to the real production situation of the poultry feed equipment itself, so regarding make greater efforts for the typical operation of the enterprise equipment. contribution.Why should the chicken feed pellet making maker be kept oiled? Generally, the importance of lubricating treatment has been highlighted again and again, mostly due to the fact that appropriate lubricating treatment can substantially decrease the wear degree of feed pellet mills and make certain smooth manufacturing job. As we all recognize, any kind of poultry feed processing equipment will inevitably have troubles such as reduced flexibility, reduced operating efficiency as well as damage after long-term usage. At this time, the maintenance of equipment certainly squanders labor and also material resource expenses, and also creates ventures to endure better economic losses. Chicken feed processing makers are no exemption. In the long-lasting usage procedure, if there is a absence of corresponding lubrication, the friction stamina in between the get in touch with parts will unavoidably boost, resulting in damage to the parts and also impacting the typical use of the entire fowl feed handling equipment. Therefore, having a good lubrication program in place before a issue takes place in the equipment will certainly be a preventive measure to extend the life of the devices.

With the opening of 2022, the sales of Richi Equipment's fowl feed handling equipments have actually been increasing progressively. However, for the small troubles caused by the wrong procedure of clients, a brief recap is as complies with:. https://preview.redd.it/atjiwdqaej4b1.jpg?width=1200&format=pjpg&auto=webp&s=f48f5f696a00ae651fc0442dd651da98538efb3d 1. What should I do if the poultry feed handling equipment can not be pushed? Encountering this problem, numerous close friends will absolutely assume that this scenario will also take place when their feed pellet devices are generating feed pellets. This is actually a headache, not just wasting raw materials, but likewise considerably raising the trouble of screening feed pellets. Today, a technologist will certainly go over the factors for this sensation with you. Lately, several customers reported that the fowl pellet maker created a great deal of powder, as well as the pellets were not tight enough, the feed pellets were always soft, so what happened? In general, is this considered a feed component or formula? Relatively slow-moving production modifications, or changes to dishes, can promptly accomplish the wanted results. Omitting feed ingredients and also solutions, we will certainly evaluate the maker setup for internal issues. ( 1) The mold and mildew wear is too large, the filter holes are flattened, and also the expansion is significant, resulting in a decline in pellet stress, impacting the pellet forming price, and causing excessive powder. ( 2) The wetness web content of the raw material is too low or expensive. If the water content is too expensive, the powder will not be excessive, yet the pellet hardness is reduced, and also the pellets of the fowl feed pelleting device are easy to loosen up. The raw product has a low water content and is tough to squeeze out, leading to way too much powder. ( 3) The poultry feed pellet maker is aging, the power is insufficient, the motor can not give enough rate, as well as the matching stress is generated to press right into pellets. ( 4) The top quality of the ring die is bad, or the compression is not too high. ( 5) Think about making use of grease. ( 6) The feeding scrape is not set up correctly, and the feeding can not go into the pressing chamber. ( 7) The placement of the cutter is wrong, and the discharge material is squeezed right into powder ( yet if the hole is commonly blocked, it is unlikely). ( 8) Moisture control describes the comprehensive control of various aspects according to different situations in the entire production process, so that the final water material of the item can get to the anticipated target of the manufacturer. The main variables impacting the final water material of feed products are: water material of feed components, water changes in the squashing stage, fluid addition in the mixing phase, steam water material, conditioning degree, die hole size as well as thickness, cooler air quantity and air-drying time, product packaging. https://preview.redd.it/sud3exdbej4b1.jpg?width=1200&format=pjpg&auto=webp&s=883b8860b465d318d70614bed011130aeb558dfd Related post: Cattle Feed Mill The influence of high quality administration and also different weather and environmental aspects ( usually, the dampness web content of pellet feed after handling will not go beyond 12.5; but in the north, pellet feed will not go beyond 13.5. If handling in summertime, due to the high ambient temperature, the optimum dampness content of ended up pellets shall not exceed 13.5. 12.5, otherwise it is very easy to mold and mildew and wear away). Feed pellets rate by more and more farmers as well as herdsmen with their distinct advantages. It is simple to shop as well as transport, and it is also helpful for pet food digestion. Compared with ordinary feed, it is rich in nutrients and also has a good market possibility. Actually, the manufacturing procedure of feed pellets is a process of distribution ratio, as long as you master the proportion. Certainly, when the pellets begin, obviously inexperienced, but do it two times. The basic poultry feed handling machine maker's handbook will discuss the distribution ratio of feed pellets, which can be described. 2. No pellets. ( 1 ) Reason. The new poultry feed handling maker was not run-in with lubricating oil or was not run-in sufficient;. The moisture web content of feed raw materials is expensive;. ( 2 ) Option. Remove the raw materials in the existing fowl feed processing machine, as well as add oil to the raw products to run in the brand-new maker, and the proportion of each time is: 1:3. Add some dry active ingredients to readjust the wetness. 3. The electric motor quits all of a sudden. ( 1 ) Reason. The voltage is as well low. The pressure between journalism roller as well as the die plate is expensive. ( 2 ) Option. Usage 4mm cable to avoid tripping throughout use. Loosen up some screws. |

The construction area is 10,0005 ㎡, and the total construction area is 81,737 ㎡, including 14 buildings such as outpatient building, medical technology research building, inpatient building, administrative building and academic lecture hall, and supporting roads, squares and greening, etc..As a major construction project of Shenzhen city, it is a modern infectious disease hospital which is compatible with the construction of the central city and ADAPTS to the planned development of Shenzhen city.It is a three-level infectious disease hospital integrating medical treatment, scientific research, prevention and protection, teaching and rehabilitation. 2、关于设置 IT 隔离电源系统的相关规范要求 Specification requirements for setting up IT isolated power system 随着社会经济的不断发展,大型综合型的现代化医院不断投入建设,因而医院电气安全可靠也引起来业界的重视,其中关于 ICU、手术室等重要场合的配电安全可靠越来越引起业界重视。尤其是关于IT隔离电源的设置。GB16895.24-2005/IEC60364-7-710:2002 标准中规定,在医疗领域2类医疗场所内,用于维持生命的、外科手术的和其他位于“患者区域”内的医疗电器设备和系统的供电回路应选用带绝缘监视的医疗IT系统供电。2008年8月1日正式实施的《民用建筑电气设计规范》中12.8.6对医疗场所采用的IT系统供电做了相应要求和规定。 With the continuous development of society and economy, large comprehensive modern hospitals are constantly put into construction, so the electrical safety and reliability of hospitals have also attracted the attention of the industry.The safety and reliability of power distribution in important occasions such as ICU and operating room have attracted more and more attention from the industry. Especially with regard to IT isolation power Settings.According to gb16895.24-2005 /IEC60364-7-710:2002, the power supply circuit for life-sustaining, surgical, and other medical electrical equipment and systems located in the "patient area" in class 2 medical facilities in the medical field shall be powered by medical IT systems with insulation and monitoring.12.8.6 In the Civil Building Electrical Design Code officially implemented on August 1, 2008, the corresponding requirements and regulations are made for the POWER supply of IT system used in medical places. (1)在2类医疗场所内,用于维持生命、外科手术和其他位于“患者区域”内的医用电气设备和系统的供电回路,均应采用医疗IT系统。 In class 2 medical facilities, the medical IT system shall be used for the power supply circuits for life-sustaining, surgical and other medical electrogas equipment and systems located in the "patient area".

However, the action response value of the earth leakage protection switch used in general general buildings is mA level (such as: 30 mA), which is far from meeting the needs of the medical field.In the special environment of hospital, leakage current poses a potential danger to patients, so special requirements are put forward for electrical safety design.In particular, those vital places, such as surgical operating rooms, intensive care units, cardiac operating rooms, etc., need to install medical IT isolation power system, the purpose of which is to ensure a safe and reliable power supply to medical appliances in the site, so as to ensure the safety of patients.When the conductor touches the heart (for example, during open-heart surgery or embedding a pacemaker), the tiny currents flowing between normally safely grounded conductors can cause micro-shocks and the possibility of death.The isolation transformer acts as a door separating the non-protected area of the medical area from the electrical wiring in the protected area. All live conductors in the protected area are isolated from the ground to prevent the dangerous current on the line insulation from causing a micro-shock.Insulation monitors must be used together with the isolation transformer, used for continuous monitoring isolation transformer secondary side of charged conductor and earth between the resistance and current, for example, in the process of the operation flow of blood and in vitro metal table may make the patient and to form a path, so there are dangerous currents, once the conductor in the medical electronic equipment form of pathways (such as leakage), will cause the macro electric shock (not all current flows through the heart) or micro electric shock (all electric current flows through the heart).Generally, the power supply network takes the ground as the reference potential, and the current in the phase line can pass through any uninsulated channel to form a circuit to the ground, which is the root cause of electric shock.Isolated power supply is the use of isolated transformer power supply, power through the isolated transformer, the original grid is no longer a reference potential.None of the output lines of the isolating transformer can form a circuit with the ground, but can only form a circuit between two output lines, which improves the reliability of power supply.The isolating transformer is used to separate the unprotected area from the protected area, and the power of the IT system is extracted at the secondary of the isolating transformer to prevent the generation of ground fault current.The IT system will be introduced into the operating room or emergency room, and a distribution box will be set in the room, and insulation monitors will be placed in the box. The use of insulation monitors can show the insulation status of the secondary load part of the isolation transformer as early as possible, and alarm signals will be provided before the insulation failure poses a threat to the person.At this time, the power will not be cut off, to ensure the continuity of power supply.Medical staff can then monitor the leakage current and the actual operation, so that the risk of personal shock is minimized. 4、深圳市某医院 IT 隔离电源系统的配置情况 Configuration of IT isolated power supply system in a hospital in Shenzhen city 深圳市某医院在所有手术室和ICU装设有医用IT隔离电源系统。具体组成包括隔离变压器、绝缘监视仪、外接报警和显示仪、电流互感器等,该系统集绝缘监视的连续性,提高防火负荷监视和变压器温度监视于一体,降低了接触电压和对地漏电流,使人身触电危险降低到最小程度,大大提高了事故预防能力,保持供电安全性。深圳市某医院选用的是德国本德尔IT隔离电源系统,其系统图如下: A hospital in Shenzhen has installed a medical IT isolated power system in all operating rooms and ICUs.Specific composition including isolation transformer, insulation monitors, external alarm and display, current transformer, etc., the system sets the continuity of insulation monitoring, monitoring, and improve the fire load transformer temperature monitoring at an organic whole, reduces the contact voltage and the floor drain current, make person get an electric shock hazard to minimize, greatly improve the ability of accident prevention, to keep the power supply security.A hospital in Shenzhen city chose Bendell IT isolated power supply system from Germany. 系统图如下: The system diagram is as follows: 1)ICU中的IT隔离电源系统如下: The IT isolated power system in the ICU is as follows: https://preview.redd.it/0sft5b680j4b1.png?width=387&format=png&auto=webp&s=43b5e501e9e57f5bf46ec28c80ee512225c4adf0 每个ICU装设一套6.3KVA IT系统(含6.3KVA隔离变压器ES710,绝缘监视仪107TD47,电流互感器STW2,外接报警显示和测试仪MK2007CBM-CN,仪器专用电源AN450)。 Each ICU is equipped with a set of 6.3KVA IT system (including 6.3KVA isolation transformer ES710, insulation monitor 107TD47, current transformer STW2, external alarm display and tester MK2007CBM-CN, special instrument power supply AN450). 2)手术室中IT隔离电源系统图 Diagram of IT isolated power supply system in operating room https://preview.redd.it/nyzbcz5a0j4b1.png?width=624&format=png&auto=webp&s=6d1215898bbb75251951d7b1dfbf50ee83d1d156 每个手术室装设有一套8KVAIT隔离电源系统(含隔离变压器8KVA、绝缘监视仪、专用电源、外接报警显示和测试仪MK2007CBM-CN)。 Each operating room is equipped with a set of 8KVAIT isolated power supply system (including isolation transformer 8KVA, insulation monitor, special power supply, external alarm display and tester MK2007CBM-CN). 3)系统设备功能: System and equipment functions: a)绝缘监视仪 Insulation monitor -绝缘监视报警系统符合IEC61557-8、IEC60364-7-710标准。 - 为医疗IT系统专用绝缘监视仪 - 绝缘监视、负荷监视和隔离变压器温度监视功能 - 带背光的液晶显示 - 绝缘监视响应值调节范围50kΩ-500Ω - 过负荷监视响应值调节范围5A-50A - 输出报警继电器 - RS485接口 - 测量值模拟电流信号输出 - 内置或外接自检按钮 - 接线监视 - 导轨安装 -交流内阻抗应至少为100kΩ; -测试电压不大于直流25V; -即使在故障情况下,其注入电流的峰值不大于1Ma; -最迟在绝缘电阻降至50kΩ时,应发出信号,并配置试验此功能的器具。 - Insulation monitoring and alarm system conforms to IEC61557-8 and IEC60364-7-710 standards. - Special insulation monitors for medical IT systems - Insulation monitoring, load monitoring and isolation transformer temperature monitoring functions - LCD with backlit display - insulation monitoring response value adjusting range 50kΩ-500Ω - Adjustment range of overload monitoring response value 5A-50A - Output alarm relay - RS485 interface -Measured value analog current signal output - Built-in or external self-check button - Wiring monitoring - Guide rail installation - ac impedance should be at least 100kΩ; - The test voltage shall not be greater than dc 25V; - Even in the case of fault, the peak value of its injected current is not greater than 1Ma; - the latest in insulation resistance to the 50 kΩ, should be a signal.And the apparatus for testing this function is configured. b)隔离变压器 Isolating transformer -满足《建筑物电气装置 第 7-710 部分:特殊装置或场所的要求—医疗场所 GB16895.24-2005/IEC60364-7-710:2002 710.512.1.6中规定:医用隔离变压器应符合IEC61558-2-15的要求。 - 容量 3.15-10kVA - 绕组内部安装温度传感器 - 噪音低于 35 分贝 - 变压器紧靠医疗场所安装,安装在柜内或外护物内以免被无意地接触期带电部分。 -变压器的二次侧额定电压 Un 不超过 250V,用于移动式和固定式设备的医疗 IT 系统采用单相变压器,其额定输出容量不小于 0.5Kva,不超过 10Kva。 -隔离变压器的金属外壳与局部等电位联结端子板联结。 - Meeting electrical installations in buildings - Part 7-710: Requirements for special installations or places - Medical places It is stipulated in GB16895.24-2005/IEC60364-7-710:2002 710.512.1.6 that medical isolating transformers shall meet the requirements of IEC61558-2-15. - 3.15-10 kva capacity - Temperature sensor is installed inside the winding - Noise below 35 decibels - The transformer is installed close to the medical site, in the cabinet or in the outer sheath to avoid inadvertent contact with live parts. - the rated voltage on the secondary side of the transformer shall not exceed 250V.

![]() | 1.电气接点测温的必要性 submitted by Acrel-electric to u/Acrel-electric [link] [comments] 电力系统的一次系统一般由供电线路(包括架空线路和电缆)、变压器、母线、开关柜等电气设备组成。其相互之间存在大量的电气连接点,由于电流流过产生热量,所以几乎所有的电气故障都会导致故障点温度的变化。例如架空线路搭接点、电缆接头、电缆中间连接处、电缆敷设弯折处、高压电缆的局部放电、高压开关柜的动静触头及其他连接处、低压电气连接处等位置过热是大型事故的征兆,也是事故多发的重灾区。
2.当前现状 多年来,由于技术水平的限制,虽然曾利用红外测温仪、红外成像仪、感温电缆、传统的点式测温系统希望解决上述问题,但都无法实现开关柜内如断路器、刀闸联接点和触头测温。目前,国内电力测温主要应用红外点测仪和光纤测温仪,而在线方式由于无法解决高压绝缘问题,所以高压开关的触点等空间有限的电气设备基本上都是处于完全无监控的状态下运行,存在重大安全隐患。
3.项目背景信息 Project background information 国内一家专业提供工业+AI 解决方案的公司,从埃及当地一家成套厂了解到,他们最近有个房建项目,配电间开关柜需要安装无线测温产品。该公司从网上找到了安科瑞,目前先做一套演示柜,测量柜内电气节点温度,由于没有启动电流,选择我司带电池无线测温传感器ATE200二代,搭配接收器ATC450-C,并且在柜子上做一个本地显示。
4.无线测温产品的优点 近年来,无线测温产品开始出现。内置电池和无线发射模块的测温传感器安装于各测温点,由于体积小,且无需任何接线,其电气安全性得到保证。传感器周期性的将测温数据无线发送至接收单元,接收单元发送数据至接收单元。 对配电间内电气设备的温度检测,采用集中接收和显示的方案,大量减少工程安装工作量,缩短安装时间,使得重要变电站的测温改造得以方便实现,对于新站的建设也具有同样的优势。 无线测温产品满足了变电站开关柜节点的实时测温的需求,在减少投资,减少工程安装量,减少维护人工和费用方面优势明显。实施本项目,能够有效提升供电系统的安全可靠运行水平,减少停电故障,对于保证正常生产、减少事故造成的损失具有重大意义。
