Zusammenfassung: | PROBLEM TO BE SOLVED: To miniaturize a vacuum circuit breaker and improve reliability thereof.SOLUTION: A vacuum circuit breaker 1 comprises: a ground tank 2; and vacuum interrupters 3, 4 accommodated in the ground tank 2. The vacuum interrupter 3 and the vacuum interrupter 4 are fixed to inside of the ground tank 2 so that an angle between an axis of a movable lead 3b of the vacuum interrupter 3 and an axis of a movable lead 4b of the vacuum interrupter 4 becomes an acute angle. A fixed lead 3a of the vacuum interrupter 3 is connected with a conductor 12 surrounded by a bushing 7 and the movable lead 3b of the vacuum interrupter 3 is inserted into an intermediate conductor 5. A fixed lead 4a of the vacuum interrupter 4 is connected with a conductor 16 surrounded by a bushing 15 and the movable lead 4b of the vacuum interrupter 4 is inserted into an intermediate conductor 5.SELECTED DRAWING: Figure 1
【課題】真空遮断器を縮小化し、真空遮断器の信頼性を向上する。【解決手段】接地タンク2と、接地タンク2内に収納される真空インタラプタ3,4と、を有する真空遮断器1である。真空インタラプタ3の可動リード3bの軸と真空インタラプタ4の可動リード4bの軸が鋭角となるように、真空インタラプタ3及び真空インタラプタ4を接地タンク2内に固定する。真空インタラプタ3の固定リード3aをブッシング7に包囲された導体12に接続し、真空インタラプタ3の可動リード3bを中間導体5に挿通して設ける。真空インタラプタ4の固定リード4aをブッシング15に包囲された導体16に接続し、真空インタラプタ4の可動リード4bを中間導体5に挿通して設ける。【選択図】図1 |
