Abstract

An insulator (100) for installation in a high-voltage switching system is described. The insulator (100) includes an electrically insulating disc-shaped carrier element (110), wherein the carrier element (110) has a first disc-shaped surface (111) including a first groove (121) configured for accommodating a first sealing element (131) and an opposing second disc-shaped surface (112) including a second groove (122) configured for accommodating a second sealing element (132), wherein at least a bottom of the first groove (121) is provided by a first metallic element (141) embedded in the carrier element (110), and wherein at least a bottom of the second groove (122) is provided by a second metallic element (142) embedded in the carrier element (110).

Description

Technical field [0001] Embodiments of the present disclosure relate to the sealing of high voltage and high current systems. In particular, the embodiments of the present disclosure relate to the sealing of compartments of gas insulated switchgear (GIS) or generator circuit breakers (GCB). More specifically, the embodiments of the present disclosure relate to the sealing of an insulator provided in a compartment of an insulated switchgear or a generator circuit breaker. Background technique [0002] In gas-insulated switchgear and circuit breakers, at least one compartment must be sealed. Because the conductor must be insulated when it leaves the compartment, the insulator itself must be sealed between the two compartments or relative to the outside. Conventionally, EPDM (Ethylene Propylene Diene Monomer) rubber or acrylonitrile-butadiene rubber (NBR) sealing ring (such as a sealing O-ring) is used to achieve sealing. Therefore, depending on the material of the seals, differen...
