摘要
断路器防跳是一项重要保护机制,旨在防止断路器因合闸于故障点而反复"跳跃",可避免断路器本身故障或电网事故扩大.断路器防跳功能的实现并不能仅靠其本身,还需要与断路器辅助接点、断路器自身的动作时间等配合,方能完整实现"防跳"功能.根据不同的断路器特性,配置合适的防跳继电器极为重要.
Abstract
The anti-trip function of a circuit breaker is an important protection feature designed to prevent repeated"tripping"caused by faults when the circuit breaker closes,thus avoiding further faults in the breaker or expanding power grid accidents.However,the anti-trip function cannot be achieved by the anti-trip relay alone but requires cooperation with auxiliary contacts of the circuit breaker,the breaker's own operating time,and other factors to fully realize the anti-trip functionality.Proper configuration of the anti-trip relay is crucial based on the characteristics of different circuit breakers.
