摘　　要：断路器的防跳通常设有保护操作箱防跳和断路器机构防跳,因此断路器控制回路接线时,必须考虑两防跳回路配合的问题。对现场调试的500 kV断路器保护操作箱防跳和500 kV断路器弹簧机构防跳回路工作原理进行分析,阐述操作箱回路和断路器机构回路配合时出现的问题,并提出相应的解决措施。The operating box anti-jump and the spring mechanism anti-jump are usually set in the anti-jump circuit of breakers, therefore, coordination between two anti-tripping circuits must be considered when anything is done about the breaker control circuit wiring.Anti-jump protection working principles of operating box and spring mechanism in the 500 kV circuit breaker are analyzed.Coordination problems between the two anti-tripping circuits are described and corresponding solutions are given.
