SF6 type outdoor high voltage hexafluoride circuit breaker (hereinafter referred to as "II III type circuit breaker") is a new type of outdoor high voltage electrical appliance with SF6 gas as an arc extinguishing and insulating medium. The arc extinguishing chamber adopts the principle of spin arc extinguishing, and the operating mechanism is divided into manual energy storage operating mechanism (type I). (Type II) energy storage spring operating mechanism, (type III) DC electromagnetic operating mechanism three, all kinds of operating mechanism and circuit breaker body perfect combination into a whole.
