Summary:The present invention relates to an interlock device for inserting or withdrawing a vacuum circuit breaker in a switch board which has improved structure for preventing the insertion or withdraw of the vacuum circuit breaker from the switch board when the vacuum circuit breaker is inputted in the switch board. The interlock device for inserting or withdrawing a vacuum circuit breaker in a switch board is an interlock device for inserting or withdrawing a vacuum circuit breaker in a switch board which has an ON button and an OFF button. The interlock device includes a switchboard, a bogie part, and a vacuum breaker. The switchboard has a rail having a cut-off hole on one side. The bogie part is formed to be movable back and forth along the rails of the switch board. The vacuum circuit breaker includes a main body installed at the upper part of a bogie part, and an interlock assembly which is formed so as to protrude in one direction to become a depressed state release the depressed state, and becomes or releases the depressed state as the main body is inserted or tripped to be inserted or released in the cut-off hole. 배전반 내에 진공 차단기가 투입된 상태에서 진공 차단기를 배전반으로부터 인출하거나 인입을 할 수 없도록 구조가 개선된 배전반 내 진공 차단기의 인입출 인터록 장치에 관한 것이다. 배전반 내 진공 차단기의 인입출 인터록 장치는 온(ON) 버튼 및 오프(OFF) 버튼을 구비한 배전반 내 진공 차단기의 인입출 인터록 장치에 있어서, 배전반과, 대차부, 및 진공 차단기를 포함한다. 배전반은 일측면에 차단 홀이 형성된 레일을 구비한다. 대차부는 배전반의 레일을 따라 전후로 이동 가능하게 형성된다. 진공 차단기는 대차부의 상부에 설치되어 배전반 내로 인입 또는 인출되는 본체부와, 일측방향으로 돌출되어 누름 상태 또는 누름 상태를 해제하도록 형성되고, 본체부가 투입 또는 트립됨에 따라 누름 상태를 해제하거나 누름상태가 되어 차단 홀에 삽입 또는 삽입 해제되는 인터록 어셈블리를 구비한다.
