Vacuum circuit breaker with coaxial coil for generating an axial magnetic field in the vicinity of the contact members of the circuit breaker

摘要

Vacuum circuit breaker, provided with a casing, in which a fixed and movable contact member are each attached to a supporting contact rod and supported therein in a mutually electrically isolated manner, and a coil coaxial to the casing and surrounding the contact members and having end connections. A first end connection of the coil is connected to one of the contact members. The contact member to which the first end connection of the coil is connected is coupled via a first coupling element to a feeder or outgoer connection of the vacuum circuit breaker. The second end connection of the coil is coupled via a second coupling element to the feeder or outgoer connection.
