<p>PURPOSE:To realize downsizing by interlocking a main circuit conductor in a gas container and a movable contactor between charge side terminals of an arrester by means of an operating lever through an insulated operating rod thereby connecting the main circuit conductor with a ground side terminal through single operation. CONSTITUTION:A main circuit conductor 3 is secured with an insulator 2 in a gas container 1 and branch conductors 19, 15 are disposed therein. An arrester 4 is fixed airtightly in the container 1 by means of an insulating member 4B. Furthermore, a ground circuit bushing 13 and a cable head 14 are secured airtightly in the gas container 1. A movable contactor 18 is arranged rotatably around a pin located at the tip of the branch conductor 19, as shown by an arrow, so that the charged side terminal 4C of the arrester 4 contacts or separates with/from the fixed contactor 13A of the ground circuit bushing 13. An operating lever 21 and the movable contactor 18 are linked through an insulated operating rod 20. The operating lever 21 is rotated around a pin 21A, as shown by an arrow, from the outside of the gas container 1 thus interlocking the movable contactor 18 therewith. According to the constitution, connection of the main circuit conductor is switched from the arrester to the ground terminal through single operation, resulting in downsizing of gas insulated switchgear.</p> |
