When the relay operates one or more contacts will operate and energize a trip coil in a Circuit Breaker and trip ( open ) the Circuit Breaker .

当继电器动作时，一个或多个接触器动作且给断路器的 脱扣 线圈 通电，从而将断路器断开。

Discussion of protection of Trip Coil in Circuit Breaker of Traction Substation

浅谈牵引变电所断路器 跳闸 线圈的保护

The reasoning process of the expert system is introduced with two fault examples : poor lubrication and trip coil fault .

最后，以锁勾润滑不足、分 闸 线圈故障2种故障为实例，分析专家系统的推理过程。

This is the total time from energizing the trip coil until the interruption of current on the primary arcing contacts .

此时间为从 跳闸 线圈受电到主触头电弧电流开断为止的总时间。
