High-Voltage Live Display Device

The indoor high-voltage live‑display device consists of three sensors and a display unit interconnected by wiring. It is suitable for indoor high‑voltage electrical equipment operating at a rated frequency of 50 Hz and a rated voltage of 40.5 kV. In addition to indicating the energized status of the circuit, it can be integrated with an electromagnetic lock to enforce interlocking of switch handles, valves, and other components. Both the live‑display function and the forced interlock are controlled by the same high‑voltage signal; however, their respective circuitry remains independent and does not interfere with one another. As long as the high‑voltage circuit is energized, even if both the display and interlock circuits fail simultaneously, the electromagnetic lock will remain in the locked position, thereby preventing inadvertent operation and unauthorized access to energized compartments.
