PURPOSE:To enable the open operation to be made by one action when current and voltage is opened by providing a second link mechanism delayingly driven for a given time from the opening of a vacuum breaker by the action of the control mechanism transferring the rotation of the rotation axis of a rotation mechanism with a given time delayed. CONSTITUTION:A series connection body for a vacuum breaker 1 and a disconnector 4 is seriesly connected to a cable way 7, and the force, when the breaker 1 is closed with the spring 107 interlocking the rotation mechanism opening/closing the breaker 1, is accumulated. The breaker 1 is opened with a first link mechanism actuated by the open operation of the disconnector 4, the rotation, of the rotation axis 22 of the rotation mechanism driven by the accumulated force of the spring 107 at that time, is transferred with a given time delayed with a control mechanism, and the disconnector is opened with an operation mechanism actuated with a second link mechanism delayingly driven for a given time from the opening of the breaker 1. Thus the opening/ closing of current and voltage can be made with one kind of a switch. |
