Backed by proven field applications and engineering validation, the Comewill factory's Indoor High-voltage Live Display Device DXN8-Q/T Type offers a practical safety upgrade for high-voltage environments. The device enables instant visual confirmation of energization status while preventing unsafe operations through automatic lockout.
The Indoor High-voltage Live Display Device DXN8-Q/T Type is a dual-function safety device integrating energization indication and mechanical lockout protection. Designed for indoor 6–40kV switchgear systems, it uses non-contact electric field sensing technology to detect voltage presence and provide immediate visual alerts, while simultaneously preventing unauthorized or unsafe access to energized equipment.

No special tools or complex setup required
Installation completed within minutes
5. Fault Indication Capability
Identifies single-phase grounding faults
Fault phase indicator automatically turns off
Speeds up troubleshooting and reduces downtime
Electric Field Sensing → Signal Conversion → LED Warning → Interlocking → Fault Indication
The Comewill Indoor High-voltage Live Display Device (Model DXN8-Q/T) utilizes electric field coupling and non-contact sensing technologies to safely and continuously monitor the live status of 6–40kV equipment in real time. The device houses three independent internal sensors, corresponding respectively to the A, B, and C phase busbars; these sensors generate signals by detecting the high-voltage electric field and transmit them to the display module.
When the equipment is live, the LED indicators flash, and the mechanical interlocking mechanism simultaneously and automatically locks the switchgear cabinet door. When the voltage is removed, the indicators turn off, and the interlocking mechanism automatically disengages—thereby achieving an intuitive combination of live-status indication and interlocking-based anti-misoperation protection. In the event of a single-phase ground fault, the indicator for the faulted phase extinguishes while the indicators for the remaining two phases continue to flash, facilitating rapid on-site fault localization.
The DXN8/QT Type is widely used in indoor high-voltage distribution systems, including:
Medium-voltage switchgear (6–40kV)
Incoming busbar systems
Circuit breakers and control cabinets
Transformer installations
High-voltage junction boxes and reactors
