10kv Lightning Arrester Js-8 Discharge Counter

 

 

The discharge counter for lightning arrester is a high-voltage electrical appliance used to monitor the discharge action of the arrester, and its structure is composed of nonlinear resistance, electromagnetic counter and some electronic components. Under the normal operating voltage, the leakage current flowing through the counter is very small, the counter is small action, when the arrester passes through the lightning wave, the operation wave and the power frequency overvoltage, the strong working current passes through the nonlinear resistance of the counter, and after DC conversion, the electromagnetic counter coil is discharged and the counter is sucked once, so as to realize the device for measuring the number of arrester actions. In the structure, the resistor sheet is used to take the voltage, the electromagnetic counter displays, the transparent glass cover, the sealing rubber pad, the bottom plate and the flange are clamped and sealed, and the high-voltage outlet end is drawn out from the center of the bottom plate.
