The Impulse Voltage Test System is a specialized testing equipment designed to simulate high-amplitude transient voltage conditions. In real-world scenarios, pulsed high voltages are commonly encountered in phenomena such as natural lightning strikes, where extremely high pulse currents and voltages occur at the point of impact and induce significant transient voltages in the surrounding areas. Similarly, switching operations within power systems can generate transient overvoltages with amplitudes often reaching tens to hundreds of kilovolts, posing serious risks to equipment integrity and personnel safety. To assess and mitigate these risks, experimental research on impulse voltage is essential. Moreover, simulating natural lightning phenomena provides valuable insight into discharge mechanisms and contributes to advancing electrical insulation and protection technologies.
Technical Advantages
1. Low Inductance Circuit Design: Utilizes resistive filtering measures, enabling the generation of standard impulse waves even under large capacitive loads and high load capacity conditions.
2. High Voltage Utilization Efficiency: Demonstrates exceptional performance with lightning impulse voltage utilization of no less than 85% and switching impulse voltage utilization exceeding 80%.
3. User-Friendly Operation: Features simple waveform adjustment, intuitive controls, excellent synchronization performance, and reliable system operation.
4. Advanced Charging Control: Employs constant-current charging with automated control technology, achieving a high degree of automation and strong anti-interference capability.
Equipment Maintenance
1. To ensure personal and equipment safety, it is necessary to regularly maintain the generator. To avoid dust accumulation, the generator should be wiped regularly, especially the surfaces of the insulation platform, insulation rod, etc. should be kept clean.
2. During operation and idle, the generator should be protected from moisture. When the surrounding air humidity is too high for a long time, the cover plate of the body should be opened; When the condensation on the inner wall of the insulation cylinder affects its use, clean hot air should be blown into each ventilation hole on the bottom to dry it.
3. After a period of use, lubricating oil should be added to each mechanical transmission part.
4. The semiconductor paint on the surface of the upper ceramic bushing near the middle flange of the high-voltage rectifier transformer should be well protected; If there is strong corona due to wear or failure, semiconductor anti corona paint should be sprayed to make the corona basically disappear.
5. If there is oil leakage or abnormal noise in the components of the generator, it should be stopped from use. It can only be put back into use after repair and passing the test.
6. If the ignition pulse system is not working properly, check whether there are short circuits or open circuits in various parts of the ignition pulse system and solve them.
