Mechanical construction
Mechanically the power cabinet is an integrated part of the ACS800-67(+C236)
converter. The converter is built as one enclosed unit that can be installed either in
the tower bottom end or in the nacelle.
The power cabinet is an incoming unit for the ACS800-67 wind turbine converter.
The power cabinet contains main switching and disconnecting devices such as main
circuit breaker and stator circuit contactor and connection terminals to the power
supply network and generator stator. The power cabinet is an integral part of the
converter line-up.
