BAYONET-TYPE CIRCUIT BREAKER HAVING A MULTIPLE FINGER INTEGRATED CONTACT BAND

摘要

The circuit breaker or under oil fuse device completes the circuit from a high voltage bushing to an under oil transformer. The bayonet device includes a bayonet assembly having a circuit element at the end and a support assembly mounted on the transformer tank and having a tubular portion extending into the oil in the tank. The tubular partion includes a pair of skirts at each contact location on it, and an elongate band of conductive spring metal material bent into a square. The band has a number of spring fingers integrally formed along its axis, with a contact button on the free end of each finger.
