高压断路器的防跳回路

Trip-proof Circuit of High-voltage Circuit Breaker

高压断路器的防跳回路作用是防止断路器合闸过程中发生“反复”跳、合的跳跃现象,确保断路器每次合闸操作时断路器只能进行一次合闸操作。介绍了一种通常采用的防跳回路,分析了它的工作原理。对几种常见故障进行了分析,提出了解决这些故障的具体方法。

The function of high-voltage circuit breaker trip-proof circuit is to prevent the appearances of ＂repeated＂ trip and making in circuit breaker making process to ensure the circuit breaker to have only one making operation for each making operation. A normally adopted trip-proof circuit was introduced with analysis of its working principle. For some kinds of normal break-downs, analysis was carried out, actual ways to solve these problems were raised.
