<p>PROBLEM TO BE SOLVED: To provide a disconnector capable of reducing the whole structure dimension of a simplified disconnector and the number of parts, and attaining easy operation. SOLUTION: This simplified disconnector is provided with a contact on every phase consisting of a movable contact 17 having a blade 17, and a stationary contact 14 which is connected and disconnected to/from the blade 17A and is mounted on a main circuit conductor 12 to which test withstand voltage is applied. The first protruding part 15 and the second protruding part 16 are bifurcatedly-formed on the blade 17A of the movable contact 17 on the phase on which a potential transformer 3 is mounted, the movable contacts 17 of respective phases and an integrated insulating shaft 18 are rotatably-mounted on the high-voltage side head 4A of a lightening arrester 4, and the base part of the blade 17A of the movable contacts 17 of the respective phases keeps a constant contact with a metal fitting 26 fixed to the high-voltage side head 4A of the lightening arrester 4 to rotate so that the end of the isolating shaft 18 may be airtightly-drawn to the outside of the container 1 to be connected to a manual lever.</p> |
