The measurement control system is an essential component of the impulse voltage (current) test generator, and its design level directly reflects the technical capability of the equipment. The charging and control functions are integrated within the unit, including the control cabinet, operation console, and measurement unit. It uses thyristor controllers and FX2n programmable logic controllers, and the design of optical fiber cables ensures stable operation in an interference environment. Due to the significant differences in industry application scenarios, the functional requirements are clearly differentiated. The standardized design of the system becomes a key technical consideration, and it needs to take into account the scalability architecture and the development of general modules.
The test force measurement system is composed of high-precision load sensors, measurement amplifiers, A/D conversion modules, and stabilized power supplies. The displacement measurement system includes photoelectric encoders, frequency doubling shaping circuits, and counting circuits. The multi-component signal processing realizes the functions of computer display, control, and data processing [1]. The system model adopts the MCS-2/000 structure, and the standard model MCS-A/B where A represents the type of control unit (divided into electrical control, touchscreen intelligent control, and measurement and control integration three types), and B corresponds to the controlled object. The charging device is divided into GC (large current full bridge type) and GV (high voltage voltage doubling type). For example, GC-6008 indicates a device with a maximum charging voltage of 60 kV and a maximum power of 8 kVA. The control unit is equipped with optional electrical control, fully automatic touch screen or intelligent measurement and control integration systems.
