Abstract
An isolator for a metal-encapsulated, gas-insulated high-voltage switching installation includes two contact supports and an enclosure. The enclosure has a longitudinal axis and is filled with insulating gas. The two contact supports are arranged in the enclosure. Each of the contact supports has a surface. A surface of a first one of the contact supports and a surface of the second one of the contact supports oppose each other to form opposing surfaces and define a separation that forms an isolating gap between the opposing surfaces. The isolator further includes a contact arrangement. The contact arrangement is movable along an operating axis between a connected state and a disconnected state. The contact arrangement electrically conductively shorts the separation when the contact arrangement is in the connected state. The longitudinal axis and the operating axis form a first angle with one another, and the opposing surfaces extend parallel to one another in a region of the isolating gap and are bent through a second angle with respect to the longitudinal axis.
