Document Type and Number:
Japanese Patent JP6713940
Kind Code:
B2
Abstract:
A heat radiator for a solid insulated switchgear unit reduces thermal resistance in a connection part between a main circuit conductor and a heat radiator, and improves attachment workability. The heat radiator, attached to a bushing conductor of the solid insulated switchgear unit, includes: a heat radiation member of metal material having a connection part with a bolt through hole; a housing of solid insulation material having a head part in which the bushing conductor is inserted and an insulation plug insertion part in which the insulation plug is inserted; and a bolt which fastens the heat radiation member to the bushing conductor. The insulation plug insertion part and the head part communicate with each other. The bolt is inserted from the insulation plug insertion part side, through the bolt through hole of the connection part projected to the inside of the head part.
