Abstract

A multi circuit selecting switchgear having a vacuum interrupter formed by sealing with a shield end plate (4,5) either open end of an insulated cylinder (3), a fixed contact (6) placed inside the vacuum interrupter and connected to a fixed holder penetrating the shield end plate at one open end, a moving contact (8) placed inside the vacuum interrupter and connected to a moving holder penetrating the shield end plate at the other open end and facing the fixed contact, arc shields (10) placed surrounding the fixed contact and the moving contact inside the vacuum interrupter and an earthed outer case (16) sealed to capsulate the vacuum interrupter through the moving side and filled with insulating gas therein, characterized in that a part of the outside of the vacuum chamber is covered with a solid insulator molding from a fixed side to a moving side, and the earthed outer case is fixed on the solid insulator.
