Special for pumping unit
The frequency conversion cabinet of the pumping unit is a series of high-performance, simple inverters independently developed by WindSun Science & Technology Co., Ltd. Under the premise of improving stability, a series of practical advanced operations such as practical PID adjustment, phase loss protection, light load oscillation suppression, flexible input and output terminals, online parameter modification, power outage and shutdown parameter storage, RS485 control, etc. control function. It provides a highly integrated integrated solution for equipment manufacturing and end customers, which is of great help in reducing system procurement and operating costs and improving system reliability.
1) The main circuit is a three-level topology which uses low voltage components for middle voltage inverter output, ensuring high reliability.
2) With more output levels than two-level circuit and RLC low-pass filter on the output side, this circuit has improved output current/voltage waveforms and ensures noiseless and vibration-less operation of motors. It can be used with ordinary motors with rated parameters.
3) Smaller dv/dt improves electromagnetic compatibility of the inverter.
4) It can automatically stabilize fluctuation of grid voltage.
5) Start voltage can be compensated. Voltage loss due to long output cable can be compensated to the largest extent.
6) Industrial/variable frequency switch is installed in the cabinet (for submersible pump).
