The Model Principle and Utilization of Discharge Counter of Lightning Arrester Manufacturers
Principle and structure of discharge counter of arrester manufacturers
In the structure, a transparent heat-resistant glass cover is adopted. Yichang Hengyuan Technology Co., Ltd. has also introduced a new style, which adopts an aluminum alloy shell, a sealing rubber gasket, a bottom plate and a flange, etc. to stop the clamping and sealing; the high-voltage outlet end is led out from the bottom plate core. Therefore, it has the advantages of high sensitivity, reliable counting precision, clear performance, light structure, elegant shape, convenient device application, and reliable sealing. The function of the discharge counter conforms to the provisions of JB2440-78 "Technical Prerequisites for Electric Counters" of the Ministry of Machinery. Principle of arrester discharge counter: The discharge counter is in waveform 8/20 microseconds, amplitude: JS-8 arrester discharge counter is 100～5000A, JS-8A type is 100A～10000A strike current and power frequency half wave In 0.01 second, the amplitude is 10A-450A (peak) and the combination of continuous flow (same polarity or different polarity) can be accurately and reliably moved for more than 20 times.
Type and influence of arrester discharge counter
The JS-8 discharge counter is connected in series with the arrester. It is an installation used to record the number of lightning arrester actions. The JS-8 type discharge counter is used for voltage levels of 6 kV to 20 kV; the application conditions are the same as the connected arresters, the altitude does not exceed 2000 meters, and the temperature is -40°C to +40°C. The arrester discharge counter is not suitable for use in the gas with severely corroded metal and insulating parts, severe corrosion and intense vibration.
The discharge counter of the arrester manufacturer and its utilization
Under the abnormal operating voltage, the leakage current flowing through the counter is very small, and the counter does not move. When the lightning arrester passes thunder wave, control wave and power frequency overvoltage, the strong task current passes through the non-linear resistance of the counter, through the DC change, discharges the electromagnetic coil to make the counter suck once, test with the arrester discharge counter action Instrument (AC and DC) measurement to achieve the installation of measuring the number of lightning arresters.
