Self powered sulfur hexafluoride circuit breaker (equipped with spring operating mechanism) is an outdoor three-phase AC 50Hz high-voltage transmission and transformation equipment, used for breaking and closing rated current, breaking fault current, or converting lines to achieve control and protection of the transmission and transformation system. It can perform three pole opening, closing, and fast automatic reclosing operations.

This circuit breaker adopts the principle of self-energy arc extinguishing, with simple structure, compact size, low operating power required, high reliability, easy installation, and low noise. It is a new generation of self-energy series high-voltage sulfur hexafluoride circuit breaker developed and developed by our company.
