前記電流センサの出力信号を基に該電流センサを
監視する点検装置において、前記操作指令が無い
とき前記電流センサの出力信号が所定値以上の状
態が所定時間継続したことで電流センサを異常と
して記憶表示すると共に、前記操作指令が有りの

ことを特徴とするしや断器操作装置の点検装置。 It consists of an operation command detection circuit that detects an operation command for the breaker, and a current sensor that detects an operation command current, and the current sensor is detected based on the operation command detection signal of the operation command detection circuit and the output signal of the current sensor. In the inspection device that monitors the current sensor, when there is no operation command, the current sensor is stored and displayed as abnormal if the output signal of the current sensor continues to be a predetermined value or more for a predetermined time, and when the operation command is present, the current sensor is stored and displayed as abnormal. 1. An inspection device for a breaker operating device, comprising an automatic monitoring circuit that stores and displays the current sensor as abnormal when the output signal of the current sensor remains below a predetermined value for a predetermined period of time.
