The Wuhan Hezhong ZGF series portable DC high‑voltage generator user manual provides safety warnings, specifications, operation steps and troubleshooting.
The ZGF series portable DC high‑voltage generator is designed for DC withstand testing of high‑voltage equipment such as surge arresters, cables, transformers and generators. It is intended for use by qualified personnel in power, mining, metallurgical and steel industries.
The manual covers safety precautions, technical parameters, functional description, detailed operating procedures, fault diagnosis, accessory list, quality assurance and service commitments. It also explains grounding requirements, discharge procedures and how to adjust over‑voltage protection. This manual is written in Chinese.
| Rated voltage (kV) | 40‑120 |
|---|---|
| Rated current (mA) | 2‑5 |
| Rated power (W) | 120‑600 |
| Unit weight (kg) | 2‑7 |
Only staff who hold a high‑voltage test qualification certificate may operate the equipment.
Turn the power switch on (green light), press the red button to connect high voltage, then adjust the voltage with the multi‑turn potentiometer.
The no‑load voltage may exceed the rated voltage by up to 10 % for ten minutes.
All grounding leads of the control box, voltage‑multiplying tube and test specimen must be connected to a single point and then to the ground network.
