Specifications
JS-8 type discharge counter (hereinafter referred to as the discharge counter) is in series lightning arrester below To record the number of lightning arrester action, JS-8 type is used in 6 KV-220 KV voltage class, JS-8 A type used in 330 KV voltage class and above the valve type lightning arrester, the using environment conditions is the same with the connected arresters. The altitude is no more than 4000 meters, the environment temperature is-40°C to +40°C.
JS-8, JS-8A Arrester Counter is composited of valves, silicon bridge rectifier, capacitors, electromagnetic counter. In the structure, it uses the transparent heat-resistant glass, sealed rubber pad, the floor flange, and other equipment for card seal; high-pressure side is drawn out from the center of bottom It enjoys the advantages of high sensitivity, the accurate and reliable records, clear and obvious display, compact structure, beautiful shape. It is easy to install and seal is reliable.
