Product Structure
Wanlida Series Medium Voltage variable frequency drive consists 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 frequency 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.
