660V 1100V 3300V 6600V Medium Voltage Inverter VFD VSD
ZUN/ZK SD3000 series Medium Voltage VFD
Description
This medium voltage 3 level VFD are widely used in which the fields of electric power, iron and steel, petroleum, mining, chemical, cement, automobiles, and utilities
It has several advantages as following:
1) Simple structure and small size;
2) Compared with the two levels, the device can achieve 2 times the voltage output with the same voltage level;
3) Reduce the common mode voltage of the motor;
4) Reduce common mode interference to the power grid;
5) It is convenient to realize the two-way flow of energy and the four-quadrant operation of the motor;
6) The output du/dt is reduced by half compared to the two levels;
7) Compared with the two levels, the number of phase voltage output levels increases and the output harmonics decrease.
Features:
1). Substantial reduction of harmonic current on power source side
2). Total inverter effi ciency as high as approximate 97%
3). Source power factor as high as 95% or more
4). High-reliability
5). Vector control
6). Easy maintenance
Application
1). Construction Materials: Kiln head cooling fans, Kiln tail heating fans, Grinders, Cement rotary kilns
2). Petrochemical Mining: Catalytic cracking unit, Hydrogenation compressor, Oil and gas transmission device, Blowers/pumps/pelletizer
