摘要
针对10 kV断路器防跳回路存在的缺陷,分析缺陷原因及串联型防跳和并联型防跳原理,并通过2个阶段的改造消除了回路改造中产生的寄生回路,完善了10 kV断路器防跳回路,提高了F-C型断路器的可靠性和安全性。
In view of the defects existing in a 10 kV breaker anti-trip circuit,analyses are done on the defect causes and the principles of circuits of serial type and parallel type,and the parasitic circuit generated in the modification of the breaker anti-trip circuit is eliminated based on two stages of upgrades,which and improves the 10 kV breaker anti-trip circuit and promotes the reliability and safety of F-C breakers.
