Main functions of lightning arrester discharge counter
Arrester discharge counter is used for a high-voltage electrical monitoring arrester discharge action, which is composed of nonlinear resistance and electromagnetic counter and some electronic components, under normal operating voltage, leakage current through the counter is very small, the counter does not move, when lightning arrester through wave, wave and operation overvoltage. The working current of nonlinear resistance strong counter can take it leisurely and unoppressively, after DC transform, the electromagnetic coil and the discharge counter move a suction device to realize frequency measurement, lightning arrester action.
Used in the structure of pressure resistance, electromagnetic coil, counter display, transparent glass cover, sealing rubber pad plate and flange are stuck and sealed, the high-pressure outlet leads from the center of the bottom plate.
Discharge counter increased the photoelectric alarm indicator, and the green indicator appears during normal operation, when the surge arrester leakage exceeds the warning value to see out of the red light, in the lightning arrester online. In addition to monitoring the function of arrester discharge, the lightning arrester monitor can also monitor the leakage current changes of arresters, and provide reliable data in time for the operation quality of arresters, so as to prevent accidents and improve the reliability of power system operation.

Discharge counter is a single pointer ten digit cycle, with counting the carry function, continuous counting instructions; 10 before entering the next cycle counting cycle, suitable for lightning arrester action area and frequent unattended places.
