ABSTRACT:
In a switchgear, oscillation of a moving current-carrying shaft and a moving contact of a vacuum valve is minimized, offset load on the contact surface is reduced, and friction the portion supporting the moving current-carrying shaft is reduced. A vacuum valve is disposed in a gas tank, one end of a moving current-carrying shaft integrally includes a moving contact of the vacuum valve, and a contact pressure adjusting spring is disposed on the other end of the moving current-carrying shaft. An operating rod extends through the gas tank, an operation mechanism is mounted on the operating rod outside the gas tank, an insulating rod is mounted inside the gas tank, and the contact pressure adjusting spring is joined to the insulating rod.
