Main features:
Using digital microprocessor to manage data and communication, using signal hierarchical processing and isolation technology, the system has strong anti-interference ability. And the equipment control is real-time, efficient, stable and reliable. Advanced optical fiber transmission control technology is used to realize the trigger and detection of high voltage thyristor, as well as the safe isolation between high and low voltage control circuits. High frequency power isolation and transmission technology is used to provide safe and reliable power supply for electronic devices working in the high voltage section. The static and dynamic voltage equalization absorption technology of resistive capacitor network ensures the reliable and safe operation of series power devices under high voltage. Using electronic EVT (Electronic voltage Transformer) technology, electronic sampling optical fiber transmission without interference, phase shift. Six start curves, adapt to the mechanical characteristics and requirements of different motor systems, automatically adjust the maximum torque of the motor six stop curves to adapt to different mechanical characteristics of the load, with adjustable final torque function, effectively prevent water hammer effect caused by pump load shutdown. Suitable for high static torque systems. ● Comprehensive protection functions: overvoltage, undervoltage, multiple overload protection curves, as well as dark current, phase break, imbalance, phase sequence error, zero sequence grounding protection, thyristor overheating, long starting time, starting interval limit, thyristor fault protection, etc. The SHMV-DN series high-voltage solid-state soft-start cabinet can be simulated by using a low-voltage (380V) motor before on-site high-voltage operation to provide technical data and guarantee for formal operation. The cabinet adopts KYN28A-12 structure and aluminum plate, which has the advantages of corrosion resistance, oxidation resistance, novel external structure, beautiful appearance, and high protection level. It can be easily combined with KYN28A-12 standard central cabinet. For the generator power supply scenario, there is a special control program, which can successfully start in the case of unstable voltage, current and frequency. ● Dual parameter adjustment function: for the two-speed motor, or in the case of power supply from the grid/generator, or in one to two runs, the parameters of the two motors are different, two sets of start and stop parameters can be entered, and the required set of parameters can be easily retrieved through the programmable terminal to start and run. ● Friendly man-machine interface, historical data statistics and query. If necessary, a touch screen interface can be added for better human-machine information exchange. Equipped with RS485 interface and optional communication protocol (Modbus/Pro bus), convenient centralized monitoring.
