Claims

[Scope of utility model registration request]

A main unit configured by collectively storing necessary equipment including a circuit breaker and switching equipment disposed between the circuit breaker and the line in a main container, and a pair of bus bar penetration openings that open in opposite directions. a busbar unit configured by housing a busbar and a busbar side disconnector in a busbar container connected to the main container via an insulating spacer for gas division, and the pair of busbar penetration openings. In a gas insulated switchgear in which a nozzle is integrally provided in each nozzle and the bus bar is connected and supported by an embedded conductor of an insulated spacer for bus bar support attached to both nozzles, One of the pair of nozzles provided in each opening is formed into a bellows shape so as to be able to expand and contract in the axial direction, and the insulating spacer for supporting the bus bar is connected to a flange portion connected to the nozzle. a buried conductor support part that supports the buried conductor, the thickness of the buried conductor support part is set to be less than the thickness of the flange part, and the buried conductor of the bus bar support insulated spacer is A gas insulated switchgear characterized in that the axial dimension is smaller than the thickness of the flange portion of the gas insulated switchgear.
