摘要： A switching controlgear of circuit breaker 100 outputs an opening command signal or closing command signal to the circuit breaker with the maximum being 1 cycle or less of wait time when the opening command signal or closing command signal is detected, and can cause the circuit breaker to open or to close at a desired phase of the main circuit current or power system voltage. The switching controlgear of circuit breaker 100 has switching control signal output time calculation means 10 and switching command signal output delay means 20. The switching control signal output time calculation means 10 calculates the switching control signal output time using the detection timing of the opening command signal or closing command signal as a reference so that the circuit breaker opens or closes at the desired phase after the total time of the switching control signal output time and the estimated opening operation time or estimated closing operation time of the circuit breaker 620 is elapsed. The switching command signal output delay means 20 outputs a delay-controlled opening command signal or a delay-controlled closing command signal to the circuit breaker after the switching control signal output time, which is the latest, is elapsed when an opening command signal or closing command signal is actually detected.
摘要翻译： 断路器100的开关控制装置在检测到开启指令信号或闭合指令信号时，将断开指令信号或闭合指令信号输出到断路器的最大值为1个周期以下的等待时间，并且可以使断路器 在主回路电流或电源系统电压的期望相位处打开或关闭。 断路器100的开关控制装置具有开关控制信号输出时间计算装置10和开关指令信号输出延迟装置20.切换控制信号输出时间计算装置10使用开启指令信号的检测定时来计算开关控制信号输出时间 或闭合指令信号作为参考，使得在切换控制信号输出时间的总时间和断路器620的估计开启操作时间或估计的关闭操作时间过去之后，断路器在期望的相位处打开或关闭。 切换命令信号输出延迟装置20在打开指令信号或关闭时经过切换控制信号输出时间（最新）之后，向断路器输出延迟控制的开启指令信号或延迟控制的闭合指令信号 实际检测到指令信号。
