Zusammenfassung:Disclosed are an apparatus, a system, and a method for inspecting a vacuum level of a vacuum interrupter. The apparatus for inspecting a vacuum according to one aspect of the present invention inspects a vacuum level of the vacuum interrupter in an electric power device having the vacuum interrupter between a power terminal and a load terminal. The apparatus for inspecting a vacuum level comprises: a monitoring unit which monitors an operation state of the electric power device; a voltage obtaining unit which obtains a first measured voltage and a second measured voltage of the power terminal and the load terminal; and a control unit which distinguishes the first measured voltage and the second measured voltage into a power terminal measured voltage and an open terminal measured voltage when the operation state of the electric power device is an open state, and determines whether the vacuum level of the vacuum interrupter is defective by comparing the open terminal measured voltage with a preset value. According to the present invention, a defect of the vacuum interrupter is detected by voltage measurement without a structural change of the electric power device, and thus a negligence accident due to poor vacuum level is prevented. 진공 차단부의 진공도 검사 장치, 시스템 및 방법이 개시된다. 본 발명의 일 측면에 따른 진공 차단부의 진공도 검사 장치는, 전원단자와 부하단자 사이에 진동 차단부를 구비하는 전력기기에서 상기 진공 차단부의 진공도를 검사하는 장치에 있어서, 상기 전력기기의 조작상태를 모니터링하는 모니터링부, 상기 전원단자 및 상기 부하단자의 제1 계측전압 및 제2 계측전압을 획득하는 전압 획득부, 상기 전력기기의 조작상태가 개방상태인 경우, 상기 제1 계측전압 및 제2 계측전압을 전원단자 계측전압 및 개방단자 계측전압으로 구별하고, 상기 개방단자 계측전압을 기 설정된 설정치와 비교하여 상기 진공 차단부의 진공도 불량 여부를 판단하는 제어부를 포함한다.
