断路器防跳回路试验方法

Test Method for Circuit Breaker Anti-tripping Circuit

断路器是一种具有关合、开断回路作用的开关装置,是电能输配变的重要环节。在正常或非正常条件下,断路器都应能保证安全分合负荷回路。为防止合闸于故障回路中的断路器发生开关跳跃现象,将断路器与防跳继电器配合组成跳跃闭锁装置,使断路器具备分闸闭锁功能,防止断路器在动作跳闸后,多次合闸、分闸,实现跳跃闭锁的目的。

Circuit breaker is a switching device with the function of switching on and off loops, and is an important link of power transmission and distribution. Under normal or abnormal conditions, the circuit breaker shall be able to ensure safe division and closure of the load circuit. In order to prevent the circuit breaker closing in the fault circuit from switching over, the circuit breaker and anti-tripping relay are combined to form a jumplocking device, which enables the circuit breaker to have the function of opening and locking. It prevents the circuit breaker from closing and tripping several times after tripping, thus realizing the purpose of jump-locking.
