Product Description

Product Description
High Voltage Lw3 Primary and Secondary Integrated Circuit Breaker Sf6 Circuit Breaker

    LW3-12 primary and secondary fusion SF6 circuit breaker (hereinafter referred to as circuit breaker) is a new generation of products developed by our company according to the requirements of the national grid primary and secondary fusion complete set of column switches.

    The circuit breaker meets the requirements of the primary and secondary fusion set of column switches in the national grid, and has the advantages of compact structure, reasonable layout and complete functions. The indicators of the circuit breaker are in line with the requirements of the State grid primary and secondary fusion complete set of column switches, and through the China Electric Power Research Institute Co., Ltd. primary and secondary fusion special testing.

    The circuit breaker adopts three-phase protection current transformer, zero sequence current transformer and zero sequence voltage sensor with unified parameters. It has the characteristics of wide measuring range, high measuring accuracy and high reliability. With the combination of primary and secondary fusion controller, it can quickly and accurately determine various line faults.
