ABNORMALITY DETECTION DEVICE OF POWER SUPPLY FACILITY

To allow a central monitoring facility side to easily grasp an abnormal state of an MCCB, and thus to quickly restore a storage battery facility to a normal state.SOLUTION: An abnormality detection device of a power supply facility of an embodiment detects abnormality in the power supply facility that supplies power from a prescribed power source to a prescribed load. The abnormality detection device of the power supply facility includes a notification circuit that detects a state of an auxiliary contact interlocking with a main contact of an MCCB provided on a prescribed power supply path and reports to a central monitoring device via a communication path when the main contact is in a non-conducting state.SELECTED DRAWING: Figure 1 【課題】中央監視設備側で容易にＭＣＣＢの異常状態を把握でき、ひいては、迅速に蓄電池設備を通常状態に復帰させることができる。【解決手段】実施形態の電力供給設備の異常検出装置は、所定の電力源からの電力を所定の負荷に対して供給する電力供給設備における異常検出を行う。そして、電力供給設備の異常検出装置は、所定の電力供給経路上に設けられたＭＣＣＢの主接点に連動する補助接点の状態を検出し、主接点が非導通状態である場合に通信路を介して中央監視装置に通知する通知回路を備える。【選択図】図１
