Zusammenfassung: | To provide an electric circuit breaker device that can be reduced in size by reducing the distance which a movable body is caused to move.SOLUTION: An electric circuit breaker device 600 comprises a part to be cut 400 that is arranged in a housing and forms part of an electric circuit, and a power source P that is arranged on a side of a first end 320 of the housing. A movable body 500 is configured to be moved by the power source P from the first end 320 toward a second end 330, and cut the part to be cut 400 accommodated in a first arc-extinguishing space X1 of the movable body 500. The housing includes an extended arc-extinguishing space X2 that is arranged to face ends 422 of separation pieces 420 of the part to be cut 400 that is cut and separated when the movable body 500 moves and stops, and is filled with an arc-extinguishing material M.SELECTED DRAWING: Figure 7
【課題】移動体を移動させる距離を短くして、小型化が可能な電気回路遮断装置を提供する。【解決手段】ハウジング内に配置され、電気回路の一部を構成する被切断部400と、ハウジングの第一端部320側に配置される動力源Pと、を備えた、電気回路遮断装置600であって、移動体500は、動力源Pによって、第一端部320から第二端部330に向けて移動しつつ、移動体500の第一消弧空間X1内に収容された被切断部400を切断するように構成されており、ハウジングは、移動体500が移動して停止した際に、切断されて分離される被切断部400の分離片420の端部422に面するように配置され、内部に消弧材Mを充填した拡張消弧空間X2を備えることを特徴とする。【選択図】図7 |
