Detailed introduction
Overview:
The intelligent measurement and control system of impulse voltage generator includes two parts: automatic control of impulse voltage generator program and automatic analysis of impulse signal measurement. The program automatic control part of impulse voltage generator is developed based on PLC of famous company, which is the replacement or substitute product of domestic shock equipment console. A variety of isolation and protection measures, such as photoelectric isolation, automatic grounding, over-voltage and over-current protection, are adopted to realize the equipment running in a safe anti-interference environment and effectively improve the reliability and safety of the program-controlled system. At the same time, the constant current charging technology and high-speed, high-resolution and high-precision conversion module are used in the process of analog digital processing to improve the program control accuracy and response.
 
Technical index
1. Nominal voltage: ± 900kV
2. Rated voltage: ± 150kV
3. Nominal energy: 20.25kJ
4. Total impulse capacitance: 0.05 MF (single pulse capacitor 0.6 MF / 75 kV, 12 sets in total)
5. Total number of stages: 6
6. Standard waveform parameters:
(1) Full wave of standard lightning impulse voltage, ± 1.2/50ms voltage utilization factor > 85% (more than 90% at no-load 300pF);
(2) Steep wave: 1000kV / US < 1500kV / uS
The parameters and deviation of impulse voltage waveform meet the requirements of gb311 and GB 16927.
7. The minimum output voltage is greater than 10% of the nominal voltage
8. Service duration: when the voltage is above 70% of the rated voltage, the charging and discharging time is once every 120 seconds, and when the voltage is below 70% of the rated voltage, the continuous operation can be achieved by charging and discharging once every 60 seconds.
