摘要

针对220 kV母联断路器机构箱操作闭锁回路老化的情况

结合现在微机保护操作箱性能比较可靠

充分利用了现在微机保护装置的可靠性能

将线路断路器保护闭锁回路由原来的单只继电器组合闭锁

改为现在的利用操作箱回路闭锁

提高了回路的可靠性

保证了微机保护的正常运行。

Abstract

Aiming to the aging condition of 220 kV bus circuit breaker operating device locking circuit and combining the reliability of the microprocessor-based protection

improvements for operating device locking circuit have been made

and the single relay combination locking was replaced by the operating device loop locking.The reliability is improved and the normal operation of microprocessor-based protection is ensured.
