GAS-INSULATED SWITCHING DEVICE

摘要

Disclosed is a compact gas-insulated switching device with a reduced number of components. A large-diameter part (16) is formed in the central part in the axial direction of a rotary shaft (15) which is driven and rotated by an operating device. An insulated operating rod (14) the other end of which is moved in an arc by the rotation of the rotary shaft (15) is formed by cast molding and encases and is formed integrally with the large-diameter part (16) of the rotary shaft (15) in a filler packed with resin. The contact connection part of the insulated operating rod (14) and a movable element (13) is formed for example on an elliptically shaped contact face (21) to contact at almost one point on the central axial line of the movable element (13) during the switching operation.
