Impact Voltage Generator Measurement and Control Integrated System

The impulse voltage generator measurement and control integrated system is a high-voltage equipment automation information platform integrating measurement and control. It consists of ultra-high-speed, large-capacity transient signal acquisition module, program-controlled amplifier, lower-level machine and actuator as the core components. The industrial control computer enables fully automatic control and fast signal analysis and processing of the whole system. Due to the use of a general industrial control computer as an information platform, it provides a broad space for the future upgrade and expansion of the impulse voltage generator measurement and control, and provides a hardware foundation for the construction of the laboratory information center. All of the above components are designed and manufactured in accordance with industrial-grade process standards, providing assurance for system reliability, stability, accuracy, and operating speed.

In view of the operating environment of the high-voltage test room, especially the characteristics of the impact test are adopted, and the anti-strong electromagnetic interference design is adopted. The technical performance index satisfies the requirements of IEC61083 and IEEE1122, GB/T16896.1-1997/200X, IEC61000 and other standards.

The operating software is written in the VC programming environment and runs based on the WINDOWS operating system, which provides guarantee for system compatibility and versatility. The interface is simple and intuitive, and easy to operate.

The weakly damped capacitor divider and the acquisition card shall provide a provincial-level measurement unit calibration test report.
