<p>PROBLEM TO BE SOLVED: To facilitate connection and disconnection of lightning arrester, reduce airtight parts and improve reliability. SOLUTION: A lightning arrester 26 disposed in a vertical direction of each phase of three phases is supported by a rotating shaft 23 provided in a gas insulating switchgear 2, a movable contact element 27 is provided on the top end of each lighting rod 26, a swinging lever 28 is fixed to a derivation unit 24 from the gas insulating switchgear 2 of the rotating shaft 23, a swinging lever 33 is provided on a control box 29 on the front side of the gas insulating switchgear 2, both levers 28 and 33 are connected by a connecting rod 34, the rotating shaft is rotated by means of the swinging lever 28 subsequent to the swinging lever 33, each lightning arrester 26 is positioned above the rotating shaft by the rotation of the rotating shaft, and thus each lightning arrester 26 is made to contact and leave each fixed contact element 22 connected to a main circuit 8 of each phase of the three phases.</p> |
