Claim:
A power switchgear comprising: a ground tank whose axial direction is set horizontally; a vacuum valve horizontally placed in said ground tank and connected to an operating mechanism; a movable side insulation supporter placed in said ground tank and supported to said ground tank; a movable side contact case supported by said movable side insulation supporter to fix and retain the movable side of said vacuum valve; a fixed side insulation supporter placed in said ground tank and supported to said ground tank; a fixed side contact case supported by said fixed side insulation supporter to fix and retain the fixed side of said vacuum valve; a movable side terminal conductor in which one side passes through a wall portion of said ground tank and is connected to said movable side contact case, and the other side is disposed to be extended above said ground tank through a movable side bushing; and a fixed side terminal conductor in which one side passes through a wall portion of said ground tank and is connected to said fixed side contact case, and the other side is disposed to be extended above said ground tank through a fixed side bushing, said power switchgear including: a pass-through hole which is formed in said fixed side contact case and has a larger inner diameter than the outer diameter of said vacuum valve so that said vacuum valve is capable of horizontally passing through and a fixed side end portion of said vacuum valve is placed by passing through; and a fixed side connection conductor attached to said fixed side contact case and connected to the fixed side end portion of said vacuum valve.
