To meet the evolving demands of power switchgear, we developed the electric earthing switch, which has been awarded a national invention patent. Maintaining the original style and interlock functions of the switchgear, the electric earthing switch incorporates a motor operating mechanism based on the original JN15, N17, N228, and IN22 series earthing switches. It retains the characteristics of the original earthing switch while enabling electric operation. Additionally, electric and manual operations do not require switching, satisfying the requirements for automated operation in power systems.
