A two-terminal grounding switch characteristic tester

Abstract

The utility model discloses a kind of both ends grounding switch characteristic tester, including host computer and with the speed sensor component of host computer electrical connection, 2 current clamp components and 2 wiring clip components;Speed sensor component is installed on the shell of circuit breaker and is connected with the moving shaft of circuit breaker;Current clamp component is respectively installed on the high-voltage cable of both sides of circuit breaker;Wiring clip component is respectively parallelly connected into the opening coil terminal and closing coil terminal of circuit breaker;Host computer is output excitation signal to the opening coil terminal and closing coil terminal of circuit breaker by wiring clip component, and according to the induced electromotive force of current clamp component feedback and the speed signal of speed sensor component feedback to calculate opening and closing parameter;Through the above structure, it can be realized "zero contact" test, without removing ground wire and climbing operation, avoid induced electric shock, high-altitude falling risk, ensure operation safety.
