2.Introduction
SF6 gas is excellent insulating and arc-extinguishing medium, and it has best performance. Such equipment is the developing direction worldwide.
I II III type outdoor SF6 circuit breakers adopt SF6 gas as rec-extinguishing and insulating medium, which is applied to self-rotated arc extinguishing theory Operating mechanism is divided into I type hand charging spring operating mechanism, II type motor charging spring operating mechanism and III type DC electromagnetic operating mechanism. All mechanism can cooperate with breaker body very well.
