Quenching contact arrangement for a compressed-gas circuit breaker
摘要
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.
