Product Structure

Wanlida Series Medium Voltage variable speed drive of By-pass cabinet, Transformer cabinet, power unit cabinet and controller cabinet from left to right.
 

Technical advantages 

  • No need of extra output filtering device
  • Directly driving the general medium voltage synchronous or asynchronous motor and the temperature of the motor will not be increased.
  • No need of motor derating operation
  • No dv/dt damage to insulation of motor and cable
  • No torque ripple induced by harmonics, and the service life of motors and mechanism devices can be extended
  • No cable length limited when voltage drop is in the allowable range.

Besides the above advantages, Wanlida medium voltage variable speed drive has the following functions and features:

  • Protection of overload, overheat, over-current, open-phase, grounding, over-voltage, negative sequence.
  • Current limited function
  • Interlock protection of control power supply
  • Two sets of control power hot standby for redundancy
  • Power cell by-pass function
  • Control cabinet automatic bypass function
  • Cabinet door opening alarm function
  • Lock-phase function
  • Synchronizing switch function between variable frequency and power frequency (optional)
  • Soft start of motors, no impact to mechanical equipment and network
  • Voltage source High-high variable frequency drive, it can realize No-step speed regulation, which makes the typical motors into intelligent motors.
  • High quality power input: By phase shifting of the secondary winding and multi-pulse diode rectifier, isolated powers can be acquired and supplied for power cells. (18 pulses for 3/3.3kV, 30/36 pulses for 6/6.6kV, 48/54 pulses for 10/11kV) By using the technique of multi-pulse rectifier, the harmonic current could be eliminated greatly.
  • Power cell communicate with controller through optic-fiber, completely electric isolated
  • Inner set PID regulator, can realize running in closed-loop
  • Multiple communication methods with host computer, isolated RS485 interface, standard MODBUS RTU, communication protocol, PROFIBUS DP (optional), industrial Ethernet communication protocol (optional)
  • Accurately fault records, can inquiry information and locate fault
  • Compact construction, reasonable layout (can do customer-design)
  • Very good protective design to dust, ferrum pulveratum, acid mist, moisture etc.
  • Bypass cabinethas a function of "five-protection", meanwhile, it has a pressure relief channel to ensure the safety of operators.
  • Modularized design of power units, interchangeable and easy to produce and repair.
