摘要
首先肯定目前使用的断路器操作装置中分(合)闸保持回路的设计思想和优点,分析了在运行中遇到的实际问题和可能造成的后果,提出在断路器分(合)闸回路中增加分(合)闸超时继电器的建议,改进后的回路对提高断路器操作回路及辅助设备的运行可靠性具有良好的作用。
The design concept of breaker on-off hold circuit in current breaker operation e-quipment and its merits are reviewed,while the problems happened in operations and their possible consequences are analyzed. It is proposed to insert overtime relays in hold circuit to improve the operation reliability of circuit breaker and its auxiliary facilities.
