ZBWKG-3000 High Voltage Reactive Power Compensation Controller adopts 16-bit single-chip microcomputer chip, AC sampling technology, LCD Chinese display, quadrant analysis and other technologies, realizes real-time data collection, communication, power statistics, historical data storage, fault alarm, grid harmonic analysis, reactive power compensation and other functions, and can be directly connected to the computer for online operation. The high-voltage reactive power compensation controller can control the automatic switching of the reactive power compensation capacitor group according to the parameters of the grid. Make the capacitor work in the best condition, ensure that the voltage qualification rate meets the requirements, effectively reduce the reactive power loss and keep the system power factor in a high range.
This manual introduces the ZBWKG-3000 reactive power compensation controller, describing its main features, functions, and technical parameters. It explains the operating conditions, model identification, and the controller's ability to improve power factor and reduce reactive power losses.
The document also covers step‑by‑step installation, wiring, and operation procedures, including RS‑232/RS‑485 communication, MODBUS protocol, and safety precautions. A troubleshooting section helps resolve common faults and alarm conditions. This manual is written in Chinese.
