A disconnector for a metal encapsulated, gas insulated high voltage switchgear includes a housing with at least a first and a second axis which intersect at a first angle. The disconnector also includes two contact carriers that are arranged on the first axis and are positioned between to contact carriers at an isolating distance by securing elements. The first axis and the second axis each form an axis of symmetry of the housing. The housing has four openings which are provided with flanges and which have the same diameter and centers located on one of the first and second axes, and are arranged at the same distance from the intersection point of the first and second axes.

Disconnector for a metal encapsulated, gas insulated high voltage

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.
