The LW primary and secondary fusion SF6 circuit breaker (hereinafter referred to as the circuit breaker) is a new generation product developed by our company in accordance with the requirements of the State Grid's primary and secondary fusion complete set of pole mounted switches for grid connection. The circuit breaker meets the requirements of the State Grid's complete set of pole mounted switches for primary and secondary fusion, and has advantages such as compact structure, reasonable layout, and complete functions. All indicators of the circuit breaker meet the requirements of the State Grid's complete set of pole mounted switches for primary and secondary fusion, and have passed the special testing of China Electric Power Research Institute Co., Ltd. for primary and secondary fusion. The circuit breaker adopts three-phase protection current transformers, zero sequence current transformers, and zero sequence voltage sensors with unified parameters. It has the characteristics of wide measurement range, high measurement accuracy, and high reliability. In combination with a primary and secondary fusion controller, it can quickly and accurately determine various faults in the line.
