To provide an incorrect operation prevention device in a simple configuration capable of preventing incorrect operations of operators during power restoration operation.SOLUTION: An incorrect operation prevention device 1 for preventing predetermined operation of an operator during power restoration operation comprises: a short circuit grounding unit 11 connected between a primary side of a disconnector 51 and the ground and for grounding the primary side of the disconnector 51, the disconnector being for switching between supplying and stopping power from a pole mounted air break switch 3 during dead-line operation; and a signal output unit 12 for outputting an incorrect operation prevention signal for preventing the operator from executing switching operation that switches an operation state of the pole mounted air break switch 3 from a dead-line state in which power supply to the disconnector 51 is stopped to a live-line state in which power is supplied to the disconnector 51 when the short circuit grounding unit 11 is connected between the primary side of the disconnector 51 and the ground.SELECTED DRAWING: Figure 1 【課題】復電作業時における作業者の誤操作を防止することができる簡易な構成の誤操作防止装置を提供する。【解決手段】 復電作業時の作業者の所定操作を防止する誤操作防止装置１であって、前記停電作業の際に、柱上気中開閉器３からの電力の供給、及び停止を切り替える断路器５１の一次側と大地の間に接続され、断路器５１の一次側を地絡する短絡接地部１１と、短絡接地部１１が断路器５１の一次側と大地との間に接続されている際に、作業者が、断路器５１への電力の供給が停止されている停電状態から、断路器５１への電力が供給される通電状態へと柱上気中開閉器３の作動状態を切り替える切替操作を行うことを防止する誤操作防止信号を出力する信号出力部１２を備えた誤操作防止装置１。【選択図】 図１
