Abstract
Disclosed is an electrical switch apparatus of the type having a metal encapsulation formed in part by a tank which is filled with an insulating gas and in which is disposed at least one vacuum switching tube per phase. The switch apparatus includes a substructure common to all phases and an attachment common to all phases having sidewalls, and a top. The attachment is supported by the substructure at the top thereof. A feedthrough plate is fastened on the top of the attachment on which the tank is supported. The top of the attachment is arranged between the sidewalls of the attachment so it could be moved relative to the sidewalls together with the tank and other parts supported by it and removed from the attachment. In the disclosed embodiment, the top of the attachment can be lowered and subsequently removed from the attachment through the front side thereof.
