The 12~24kV indoor high-voltage grounding switch is a safety protection device, not an operational switch for interrupting load current.
Primarily installed within high-voltage switchgear, it provides reliable personnel safety grounding for equipment undergoing power-off maintenance.
This 12/24kV earthing switch is used for medium voltage power system safety protection. It offers stable performance, simple structure and safe operation for substation and industrial use.
• Main Modules: SF6 insulating bushing (epoxy resin encapsulation with sealed chamber), three-phase conductive circuit, operating mechanism base;
• Auxiliary Accessories: Insulating supports, insulating covers, conductive connectors, mounting fasteners, supporting indoor cabinet assembly.
• SF6 Insulation: Utilizes SF6 gas as the insulating medium, offering superior insulation properties and suitability for indoor high-voltage enclosed environments;
• Indoor Adaptability: Components feature a cabinet-embedded design without outdoor weatherproof structures, tailored for internal switchgear installation;
• Sealed Design: Insulating bushings employ a sealed structure to ensure low SF6 gas leakage and extended maintenance intervals.
• Grounding Protection: Reliably grounds circuits during maintenance to ensure personnel safety;
• Insulation Isolation: Creates an insulating gap with the grounding terminal after disconnection, restoring normal circuit operation;
• Interlock Compatibility: Enables operational interlocking with the switchgear’s main switch (e.g., grounding only permitted after main switch disengagement).
