Application

This starting autotransformer is applicable to three-phase squirrel cage motor of AC50HZ/380V with power 14-300kW for auto-induction voltage-reduced starting, when the starting is finished, the transformer will be cut off.

Main fucntions and features

This autotransformer is a kind of single-turn transformer,the primary and secondary sides use the same winding,and the voltage ratio is fixed. When comparing with the general transformers of the same capacity, this autotransformer has advantages of

simplified structure,less material, smaller volume, etc., especially shows its economical efficiency when the voltage ratio is about 1. It is widely applied to the high power transmission transformers with similar voltage, besides, it is applicable to more than 10KW voltage-reduced starting cabinet of asynchronous squirrel cage motor .
