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.
