Electrical gas-blast switch

A contact arrangement for use with a pressurized-gas circuit breaker wherein the nozzle arrangement is provided with a nozzle-shaped arc electrode having an annular slot disposed between its interior and exterior surfaces, and with an annular body of ferromagnetic material arranged in the aforesaid slot.

Contact arrangement for pressurized-gas circuit breaker

A contact arrangement for a pressurized-gas circuit braker, wherein the contact arrangement comprises a first tubular contact member and a second tubular contact member axially arranged therewith. The contact arrangement is further provided with a hollow cylinder means of ferromagnetic material which is arranged in the interior of the first tubular member and is formed from a multiplicity of laminated metal washers which are insulated from one another and are arranged axially with respect to the first tubular member.

Contact arrangement for a pressurized gas circuit breaker

A method for manufacturing a contact for use with a gas-blast circuit breaker wherein the contact has slots in an end face which are filled with an arc-resistant plastic material and wherein the method comprises the steps of forming a plurality of contact members and cementing the members together employing an arc-resistant plastic to form a structural unit.

Method for the manufacture of contacts for gas-blast circuit breakers

The invention is directed to a quenching and contact arrangement for a compressed-gas circuit breaker. The arrangement includes a tubular contact piece and a contact piece axially arranged therewith. An arc is drawn between both contact pieces when the circuit is interrupted under load, the arc then being blasted by a stream of compressed-gas. A turbulence grid is arranged in the flow path of the stream. The turbulence grid is configured in the form of a tube of insulating material with perforations in the cylinder surface thereof which directly encloses the arcing space in the course of the circuit-breaking motion.
