for electrical networksmodularhigh-voltage

• Nominal voltage: 3000kV • Rated stage voltage: 200kV × 15 levels • Nominal energy: 450kJ • Total capacitance: 0.1µF (30 × 3µF/100kV capacitors) • Waveform: lightning impulse 1.2/50µs, switching impulse 250/2500µs, chopped wave 2–6µs • Duration: ≥70% rated voltage, 120s operation cycle • Divider accuracy: ≤±1%, response time ≤100ns The Huazheng 3000kV Impulse Voltage Generator is specially designed for high-voltage equipment testing, including transformers, insulators, bushings, and GIS systems. It generates standard lightning impulse full waves, operating impulse waves, and chopped impulse waves, strictly conforming to GB/T 311, GB/T 16927, and other international standards. With modular tower design and robust construction, it provides reliable performance for insulation coordination and withstand voltage verification in laboratory and field environments. Key advantages include an oil-immersed charging transformer, high-voltage rectifier silicon stack, and constant current charging system for stable output. The structure features 15 stacked stages with oil-immersed capacitors, resistors, and triggered ball gaps, ensuring reliable discharge synchronization. Equipped with weakly damped capacitor dividers, truncation gap device, and modular accessories, this generator provides excellent waveform fidelity and repeatability, making it ideal for power research institutes, manufacturers, and high-voltage test laboratories.
