Patent number: 8198562Abstract: The invention relates to a vacuum switch, especially a vacuum circuit breaker, for medium and high voltages, comprising a mobile switch unit arranged inside a vacuum switch compartment (1) and provided with mutually mobile elements including a contact tappet (17), an insulator (18), and a driving or switching rod (11) introduced into the vacuum switch compartment (1) by means of metal bellows. Said vacuum switch also comprises a fixed contact inserted into the housing of the vacuum switch compartment (1). The upper end of the insulator (18) is fixed to the contact tappet (17), and the lower end of the insulator (18) is fixed to the driving or switching rod (11). The contact tappet (17) is connected to a conductor (8) by a flexible, electroconductive connection (20), said conductor being electroconductively connected to at least one laterally arranged output contact (6).Type: GrantFiled: September 7, 2007Date of Patent: June 12, 2012Assignee: Switchcraft Europe GmbHInventors: Klaus Bodenstein, Detlef Lange

Patent number: 7679019Abstract: An electrical switching system, preferably a medium-voltage switching system, has a power switch or load switch, a disconnecting switch, and a grounding switch configured as a vacuum switching chamber. Low separation distance lengths and a more compact construction of a switching system is achieved by means of a housing in which the disconnecting switch, configured as a vacuum switching chamber, the grounding switch, and the power switch or load switch are disposed, and in which a central switch is disposed, with which the vacuum switching chambers of disconnecting switch and grounding switch can be mechanically activated. Electrical connections between connector contacts of power switch or load switch, disconnecting switch, and grounding switch can be produced.Type: GrantFiled: March 9, 2007Date of Patent: March 16, 2010Assignee: Switchcraft Europe GmbHInventors: Klaus Bodenstein, Detlef Lange
