DSN-JZ is an indoor electromagnetic lock designed for power systems, primarily used for preventing incorrect operation of high-voltage equipment.
As an electrically controlled mechanical interlocking device, it is primarily used for:
• Preventing misoperation of high-voltage switchgear (such as disconnectors and earthing switches) during disconnection/connection;
• Implementing forced interlocking for switchgear cabinets, cabinet doors, and other components to prevent accidental entry into energized compartments;
• Integrating with the “five-prevention interlocking” system to ensure safe power operation.
