<p><P>PROBLEM TO BE SOLVED: To provide an operation device for a gas-insulated switchgear (C) equipped with a current blocking device or an electric circuit input device constituted of a fixed contact and a movable contact (A), which is provided in a grounded container with insulation gas injected inside, drives the movable contact (A) to a blocking direction or an input direction, reduced in energy loss to be accumulated and capable of arbitrary continuous operation of input and blocking. <P>SOLUTION: An blocking operation is carried out by a spring operation device (100), an input operation is carried out by a separately independent oil pressure operation device (200). Operation ends of the spring operation device (100) and the oil pressure operation device (200) are coupled through a connection link (300) and a lever (12), and driving energy by the oil pressure operation device can be accumulated at a spring (10) of the spring operation device (100). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
