摘　　要：分析直流旁路断路器的防跳功能与常规断路器不同之处,指出云广直流旁路断路器的特点是其防跳继电器采用闭锁分闸回路设计,在出现可能的断路器跳跃的情况下,优先保证旁路断路器最终状态为合闸状态,以实现其防跳功能。The difference of the anti-pumping functions between the DC bypass breaker and general circuit breaker is analyzed,and it is pointed out that adopting lockout tripping circuit is the specialty of the DC bypass breaker in Yunnan-Guangdong ±800 kV DC project,which ensures in priority that the final status of the DC bypass breaker keeps in close state to realize anti-pumping function in the case where the breaker pumping is possible.
