Product Description:
type lightning arrester discharge counter action verification
Principle
Figure 1 shows the principle
for the principle of action visitor counter type JS hookup. Figure 1 (a) for JS type action visitor counter the basic structure, the so-called double valve chip structure. When lightning arrester action, discharge current flow through valve slice R1, the pressure drop in R1 by valve slice R2 give capacitor C charging, then C again to assolenoid style of inductance coil L discharge visitor counter, make its rotation 1 case, remember one times. Change R1 and R2 resistance, can make the visitor counter with different sensitivity. Generally minimum operating current for 100A (8/20 mu s) current impulse. Because R1 there are certain pressure drop, will make the lightning arrester residual pressure increases, so it is mainly used for 40kV above the high-pressure arresters.
