Principles and utilization of discharge counter models of lightning arrester manufacturers
Principle and structure of discharge counter of lightning arrester manufacturer
The structure adopts a transparent heat-resistant glass cover. Yichang Hengyuan Technology Co., Ltd. has also launched a new model, which uses an aluminum alloy shell, sealing rubber gasket, base plate and flange for snap-in sealing; the high-voltage outlet is led from the center of the base plate. Therefore, it has the advantages of high sensitivity, accurate and reliable counting, clear and distinct performance, light structure, beautiful appearance, easy installation and use, and reliable sealing. The performance of the discharge counter complies with the provisions of JB2440-78 "Technical Conditions for Electrical Counters" of the Ministry of Machinery. Principle of arrester discharge counter: The discharge counter is in the waveform of 8/20 microseconds, amplitude: JS-8 arrester discharge counter is 100~5000 A, JS-8A type is 100 A~10 Under the combined action of the impact current of 000A and the power frequency half-wave of 0.01 seconds, with the amplitude of 10A-450A (peak) freewheeling (same polarity or different polarity), it can operate accurately and reliably more than 20 times
Arrester discharge counter model and function
The JS-8 discharge counter is connected in series to the arrester. It is a device used to record the number of operations of the arrester. JS-8 type discharge counter is used for voltage levels of 6 kV to 20 kV; the environmental conditions where it is used are the same as the connected lightning arrester, the altitude does not exceed 2000 meters, and the ambient temperature is -40°C to +40°C. Arrester discharge counters are not suitable for use in gases that severely corrode metals and insulating parts, and in places with severe corrosion and strong vibrations.
Arrester manufacturer’s discharge counter and its use
Under normal operating voltage, the leakage current flowing through the counter is very small, and the counter does not move. When the arrester passes through lightning waves, operating waves and power frequency overvoltage, a strong working current passes through the non-linear resistance of the counter, changes in DC, discharges the electromagnetic coil and causes the counter to actuate once. The device for measuring the number of arrester operations is measured with an arrester discharge counter action tester (AC/DC).
