て、前記検出回路の出力側に、復帰時間が前記しゃ断器
の動作時間より長い時間に設定された瞬時動作限時復帰
回路を接続したことを特徴とする静止形保護継電器。The input signal is introduced into the detection circuit, which determines whether or not there is an abnormality in the protected circuit.If an abnormality occurs, it is displayed on the display via the self-holding circuit, and the signal is sent via the power amplification circuit and output relay. In the device for operating the circuit breaker, an instantaneous operation time limit recovery circuit whose recovery time is set to be longer than the operation time of the breaker is connected to the output side of the detection circuit. Static protective relay.
