一种高压断路器防跳功能试验新方法

A New Test Method for Anti-Jump Function of High Voltage Circuit Breaker

由于不同时期对防跳回路反措要求、设计原则不同,造成现场防跳功能实际使用情况五花八门。文章从原理上重点介绍防跳功能中“分位防跳”在断路器手合于故障、重合于故障中发挥至关重要的作用,并提出具体的整改方案和完善的现场试验方法。

With the deepening of everyone’s understanding of the anti-jump principle,the verification of the antijump function in the process of infrastructure construction and maintenance has been gradually emphasized.Due to the different requirements and design principles for the anti-jump circuit countermeasures in different periods,the actual use of the on-site anti-jump function is varied.The article focuses on the principle of the anti-jump function of“divided position anti-jump”which plays a vital role in the hand-closing and coincident faults of the circuit breaker,and proposes a specific rectification plan and a perfect field test method.
