Specifications

Wanlida medium voltage adjustable speed drive
Product Structure
Wanlida Medium voltage adjustable speed drive consists of By-pass cabinet, Transformer cabinet, power unit cabinet and controller cabinet from left to right.
 
Working Principle
Wanlida medium voltage adjustable speed drive adopts multi-level cascaded power unit technology to obtain MV directly by means of overlap wave. Low voltage power unit is an actually improved motor variable speed drive, which takes full advantage of mature technology. Wanlida adjustable speed drive belongs to High-high voltage source inverter, the customer can connect medium voltage (3/3.3/4.16/6/6.6/10/11KV) directly to input terminal of VSD, and then Wanlida adjustable speed drive output medium voltage (3/3.3/4.16/6/6.6/10/11KV) correspondingly, no need output step-up transformer.

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.
Factory Acceptance Test Platform
Wanlida built the first-class high voltage and big capacity adjustable speed drive test platform to realize Factory full load test before delivery.
