Description
Key Functionality
• Status Monitoring: Induces the live status of three-phase high-voltage circuits via the interfaces corresponding to L1 (yellow), L2 (green), and L3 (red);
• Interlock Control: The 3 sets of “OFF/ON” switches on the right can work with devices like electromagnetic locks to achieve misoperation-prevention locking (e.g., locking the operating mechanism when the circuit is live);
• Passive Design: Typically uses the capacitive voltage division principle to sense live status, requiring no external power supply.
Key Technical Parameters
| Feature Category | Description |
| Applicable Voltage | Compatible with medium and high-voltage systems (e.g., 10kV, 35kV) |
| Installation Method | Embedded installation on switchgear panels |
| Safety Function | Supports forced locking when the circuit is live, enhancing operational safety |
Application Scenarios
It is mainly used in indoor high-voltage power distribution equipment (such as 10kV/35kV switchgear, ring main units, and cable distribution boxes), and is one of the key auxiliary devices for implementing “five-prevention interlocking”.
