Product Description
Lightning arrester discharge counter is used to monitor the lightning arrester discharge action of a high-voltage electrical appliances, its structure by the non-linear resistance, electromagnetic counter and some electronic components. Under normal operating voltage, the leakage current flowing through the counter is very small, the counter does not act. When the arrester through the lightning wave, operating wave and frequency over-voltage, the strong working current from the counter of the nonlinear resistance through, after DC conversion, the electromagnetic coil discharge and make the counter suction once, to achieve the measurement of the number of lightning arrester action device. In the structure of the resistor sheet to take the pressure, electromagnetic coil action, counter display, transparent glass cover, sealing rubber gasket, bottom plate and flange sealing card, high-voltage outlets from the centre of the bottom plate. Lightning arrester discharge counter due to poor sealing, in the process of operation may enter the moisture and water, so that the internal components corrosion, resulting in the normal action, the reliability of the counter action for the power system is very important, it is an important parameter to record the lightning arrester in normal operation by the number of lightning strikes statistics. It can provide power system staff with targeted inspection of lightning arrester important instrumentation. Therefore, the Regulations provide that at least one inspection should be carried out annually.
