Claims (1)
、又は電圧調整装置の異常によるものか−を弁別して検
出する過電圧検出装置において、き電量線の電圧が設定
値以上になると動作する直流過電圧リレーと、電車負荷
の存在時に動作する接点と、限時継電器とを夫々直列に
接続し、前記限時継電器の動作によって電圧調整装置の
異常を検−出することを特徴とする過電圧検出装置。In an overvoltage detection device that distinguishes and detects whether the voltage increase on the DC feeding power line is due to a reduction in the train load or due to an abnormality in the voltage regulator, the DC overvoltage detection device operates when the voltage on the feeding power line exceeds a set value. An overvoltage detection device characterized in that an overvoltage relay, a contact that operates when a train load is present, and a time relay are connected in series, and an abnormality in a voltage regulator is detected by the operation of the time relay.
