To enable appropriate automatic landing operation when a power abnormality occurs in a main power circuit connected to a circuit breaker.SOLUTION: An elevator power supply control device has a first circuit breaker 111 arranged on a control panel 110 and connected to a power supply circuit to which main power is supplied, and a second circuit breaker 101 connected to the power supply circuit at a location separate from the control panel 110. The second circuit breaker 101 has an auxiliary contact 101a that turns off in conjunction with the interruption of the main contact, and an alarm contact 101b that turns on when the circuit breaker detects an abnormality in the main power supply. When an interruption in the supply of main power is detected with the alarm contact 101b turned on, power is supplied from a power failure battery 116 to an elevator main circuit 115, and the elevator performs automatic landing operation.SELECTED DRAWING: Figure 2
【課題】遮断機に接続された主電源回路での電源異常時に、適切な自動着床運転が行えるようにする。【解決手段】制御盤110に配置され、主電源が供給される電源回路に接続された第1の遮断機111と、制御盤110とは別の箇所で電源回路に接続された第2の遮断機101とを有する。第2の遮断機101は、主接点の遮断に連動してオフになる補助接点101aと、遮断機で主電源の異常を検知したときオンする警報接点101bとを有する。そして、警報接点101bのオンを検出した状態で、主電源の供給停止を検出したとき、停電用バッテリ116からの電源をエレベーター主回路115に供給して、エレベーターの自動着床運転を行うようにした。【選択図】図2
