The KDZD‑GTU‑GK807 is an integrated cabinet‑type teaching‑oriented partial discharge simulation equipment developed for power‑specialty teaching and scientific research training. It can highly reproduce various typical partial‑discharge phenomena occurring in running high‑voltage switchgears and other high‑voltage electrical equipment. Multiple insulation‑defect discharge modes including air‑gap discharge, floating discharge, surface discharge and particle discharge can be reproduced on this platform. It delivers safe, intuitive and repeatable experimental conditions and complies with relevant national standards and industry guidelines. The whole machine adopts fully‑enclosed metal safety cabinet structure with built‑in partial‑discharge‑free high‑voltage source and coupling capacitor. Replaceable discharge model electrodes are controlled by external handles for convenient discharge‑type switching. Multiple sensor interfaces are reserved to realize synchronous comparison tests for different partial‑discharge detection technologies. Its compact layout enables flexible deployment in classrooms, laboratories and outdoor training sites, while closed high‑voltage isolation design eliminates high‑voltage exposure risks and protects teachers and students during repeated teaching operations.
