Medium-voltage Inverter

WIN-HV Series medium-voltage frequency inverter


Power range

Voltage：3kV～10kV  Single-unit power：315kW～12000kW

Product’s introduction

The WINNER WIN-HV series medium-voltage frequency inverter designed and manufactured by WINNER has prominent performance and high reliability with low cost. It is of AC-DC-AC voltage type inverter with main loop of multi-level topology circuit. The control mode adopts SPWM technology. And the input uses isolated transformer of multiple technology, while the output is fulfilled by the solution of phase-shifting tandem multi-unit and medium-voltage to medium-voltage direct conversion.

Many years of technical experience enabled Winner and its staff to have developed inverters with low harmonic content, which is in a leading level in domestic. Perfect output voltage sine wave provides the inverter with stability of motor’s operation during the whole speed regulation range. The low input current harmonics almost has no any disturbance to the grid and this ensures the operation reliability of the surrounding electric equipments.

This series inverter can drive and regulate the medium-voltage motor in almost all kinds of application area. The speed regulation is smooth, and the efficiency and power factor is enviable.  In particular, nowadays the world is in short of energy. Winner inverter can bring great economic effect when used for blowers and pumps.

This series inverter consists of three main parts, transformer cabinet is on the left, and power unit cabinet is in the middle, while control cabinet is on the right. To improve the stability of the control circuit and to make the debugging more convenient, the control cabinet door was put on the right of the machine.  This series product adopts cabinet structure with forced air cooling. And the big capacity machine adopts the cooling mode of water-cooled, air-closed circulation.   The wiring terminal of input and output of the complete machine was placed on the lower left back. It is easy for connection

Application area

WIN-HV medium-voltage frequency inverter has been widely used for the medium-voltage motor’s speed regulation, energy saving, soft starting and intelligent control in the area of power supply, iron and steel, HVAC, oil, construction, mine and etc.

  • Heat power station: coal grinding machine, blower, draught fan, dust exhaust fan, circulating pump, water-feeding pump.
  • Iron and steel plant, metallurgical plant: water-feeding pump, dust exhaust fan, draught fan, oxygenator.
  • Mine: slurry pump, ventilator.
  • Oil: water injection pump, oil pump.
  • Chemical plant: compressor, blower, circulating pump.
  • draw off pump, supply pump, purifying pump, sewage pump in urban power supply and sewage disposal:
  • The grinder, pump, draught fan, dust fan, supply blower in cement plant and ceramic plant
  • others: the blower for medicine, paper making, food

Feature

Years of accumulative technology of high-power drive increases the product’s power supply to be 8000kw.
Unique low-induction bus structure ensures stable operation of the power unit.
Distinctive cooling design and components layout enable the inverter to work more reliably.

Non-disturbance switch between grid frequency and inverted frequency makes sure that the equipments can work uninterruptedly.
