This manual explains the overview, specifications, installation, wiring, and troubleshooting of the DGQCC DXW(N) high‑voltage live‑display lock device.
The DGQCC DXW(N) is a non‑contact, sensor‑type high‑voltage live‑display lock designed to indicate energized conditions and prevent accidental operation of electrical equipment. It works for AC 50 Hz systems with rated voltages from 40.5 kV up to 550 kV and can be installed both outdoors and indoors.
The guide covers environmental requirements, main technical parameters, mechanical structure, wiring diagrams, installation steps, adjustment of sensitivity, and common fault diagnosis. It also describes how the device interfaces with various anti‑misoperation locks such as electromagnetic, mechanical program, and micro‑computer locks. This manual is written in Chinese.
