Transformation system equipment built in tower bottom of marine wind generating set

The utility model discloses relates to the field of wind power generation, and provides transformation system equipment built in a tower bottom of a marine wind generating set. Aiming at special marine environments such as humidity, salt-spray fog corrosion and the like, the transformation system equipment adopts an integrated arrangement scheme, that is, all cabinet bodies are arranged side by side in a layered manner, so that all the transformation system equipment is centralized in a tower, the internal space of the tower is fully used, damage to the transformation system equipment caused by marine humidity, salt-spray fog corrosion, lightning stroke and other external factors can be avoided effectively, the service life of the transformation system equipment is prolonged, the cost is greatly reduced, the integral structure of the scheme is compact, and the practicability is high.
