Abstract
A switching arrangement has a plurality of at least two contact arrangements and a blasting arrangement for blasting the contact arrangements with insulation gas. The at least two contact arrangements each have a first contact piece and a second contact piece which can be moved relative to one another in order to form an electrical connection when the first contact piece and the second contact piece are in contact and to form an insulation zone when the contact pieces are isolated from one another. The blasting arrangement has at least two blowing volumes, wherein a first contact arrangement can be supplied with insulation gas by a first blowing volume and wherein a second contact arrangement can be supplied with insulation gas by a second blowing volume.
Claims15
A switching configuration, comprising:
- a plurality of contact configurations having at least two said contact configurations, each of said contact configurations containing contact pieces including a first contact piece and a second contact piece which can move relative to each other in order to form an electrical connection in a state in which said first contact piece and said second contact piece touch each other, and to form an insulating gap in a state in which said first contact piece and said second contact piece are isolated from each other;
- a blasting configuration for blasting said contact configurations with insulating gas, said blasting configuration having a plurality of blasting volumes, a first contact configuration of said contact configurations being supplied with said insulating gas by a first blasting volume of said blasting volumes, and a second contact configuration of said contact configurations being supplied with said insulating gas by a second blasting volume of said blasting volumes;
- and
- said blasting configuration having a volume-displacement piston-and-cylinder configuration, at least one contact piece from said first contact configuration and from said second contact configuration being arranged so that said at least one contact piece is stationary on said volume-displacement piston-and-cylinder configuration.
