Patent number: 4577075Abstract: An earthing switch for gas-insulated switchgear apparatus is disclosed, in which conductor within an enclosure is provided with a stationary contact, and a moving contact is movably provided to connect with and disconnect from the stationary contact by an operating mechanism within an operating mechanism case which is mounted on a branch tube of the enclosure interposing an insulating plate therebetween. For connecting the moving contact to the enclosure electrically, a plurality of earthing bars are employed, and further, directions of electromagnetic forces generated between the moving contact and individual earthing bars are considered in the connection of the earthing bars. By virtue of the connection of the plurality of earthing bars, the influence of the electromagnetic forces acting on the moving contact can be reduced to a great extent.Type: GrantFiled: January 16, 1985Date of Patent: March 18, 1986Assignee: Hitachi, Ltd.Inventors: Kenji Akita, Minoru Sakaguchi, Hiroshi Suzuyama
