Wanlida medium voltage adjustable frequency drive
Wanlida Medium voltage adjustable frequency drive consists
of By-pass cabinet, Transformer cabinet, power unit cabinet
and controller cabinet from left to right.
Wanlida medium voltage adjustable frequency 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
frequency 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 frequency drive output
medium voltage (3/3.3/4.16/6/6.6/10/11KV) correspondingly,
no need output step-up transformer.
