摘　　要：针对广州地铁2号线直流馈线开关跳闸后异常闭锁现象,结合联跳保护的原理和特点,对联跳信号的产生、传递、接收过程进行深入的分析和严格的现场测试,确定开关异常闭锁的原因,提出通过外围电路调整优化双边联跳功能的方案,取得较好的应用效果。In view of the DC circuit breaker latching on Guangzhou metro Line 2, this article introduces the process of generation, transmission and receiving of inter-tripping signals. Based on the theory and characteristics of inter-tripping protection, the reason of circuit breaker latching is revealed and an improved scheme of two-way inter-tripping protection by changing the peripheral circuit is put forward.
