Characteristics of Shanxi Fire Power Status Monitor

Precautions for using current and voltage sensors: The sensor's ability to resist external magnetic fields is: when the distance from the sensor is 5-10cm, a current that exceeds twice the original current value of the sensor can resist the magnetic field interference generated. When wiring three-phase high current, the phase to phase distance should be greater than 5-10cm. In order to ensure that the sensor operates in the best measurement state, a simple typical voltage regulator power supply as shown in Figure 1-10 should be used. The magnetic saturation point and circuit saturation point of the sensor give it strong overload capacity, but the overload capacity is time limited. When testing the overload capacity, the overload current of more than twice should not exceed 1 minute. The temperature of the primary current busbar shall not exceed 85 ℃, which is determined by the characteristics of ABS engineering plastic. If users have special requirements, high-temperature plastic can be selected as the shell.

When used in high current DC systems, if the working power supply opens or malfunctions due to certain reasons, the iron core will produce significant residual magnetism, which is worth noting. Residual magnetism can affect accuracy. The demagnetization method is to pass alternating current through the primary side without increasing the working power supply and gradually reduce its value. The ability of a current sensor to resist external magnetic fields is that when the current exceeds twice the original current value of the sensor at a distance of 5 to 10cm, the magnetic field interference generated will be resisted. For current wiring, the distance between the two phases should be greater than 5-10cm. In order to ensure accurate measurement of the current sensor, a simple and typical voltage regulator should be used. The magnetic saturation point and circuit saturation point of sensors give them strong overload capacity, but the overload capacity is time limited.

Wuxi Haigang Electronic Technology Co., Ltd. is committed to providing customers with better power monitoring solutions. The company produces power monitoring systems, energy management systems, electrical disaster monitoring systems, and fire-fighting equipment. The power monitoring system, fire door monitoring system, intelligent evacuation emergency lighting system, intelligent lighting control system, intelligent power meters, rail type energy meters, intelligent motor protectors, fault arc detection devices, intelligent reactive power compensation capacitors, and intelligent fire inspection cabinets are highly praised in the industry for their unique design concepts, appearance, and excellent quality.

Compared to automatic fire alarm systems and electrical fire monitoring systems, the fire power monitoring system is simpler. During the drawing process, attention should be paid to the above issues. At the same time, writing detailed and comprehensive design instructions will output a high-quality design drawing for the fire power monitoring system. It is not difficult to do a good job in designing the fire power monitoring system drawing. Box number, B17APE2 is the distribution box number, which can be read out through the distribution box number. This distribution box is the second power distribution box in the underground 17th fire zone. The 'voltage sensor' is connected to the fire power monitoring host in the fire control room using a ZR-RVSP (2x1.0) communication bus and a ZR-RVS2X1.5 24V power line.

Lem was the first to achieve sensor miniaturization in LTSR products ten years ago. At that time, a good way to ensure performance advantage was to use closed-loop Hall effect technology, and Lem designed a customized closed-loop ASIC. With the development of ASIC technology, Hall open-loop sensors also have dedicated ASICs, making the performance of open-loop sensors close to the level that closed-loop technology can achieve. Open loop ASIC technology is not only easier to implement in terms of miniaturization, but also meets the market's demand for cost advantages, while having a simple structure and low power consumption.

Good dynamic performance: fast response time, can be less than 1us; The response time of ordinary transformers is 10-20ms. Working bandwidth: signals within the frequency range of 0~100KHz can be measured. High reliability, long average time between failures: the average time between failures is less than 510 hours. Strong overload capacity and wide measurement range: 0- tens of amperes to tens of thousands of amperes. Small in size, lightweight, and easy to install. Current sensor is a type of sensor that can efficiently and quickly detect relevant information about current. With the rapid development of modern technology, the application of current sensors has become very widespread.
