Suitable for three-phase AC frequency 50-60Hz, voltage 380V, power 14~350KW squirrel cage motor for automatic coupling buck start,To improve the impact on the auxiliary power network when the motor starts.

The autotransformer is a single-turn transformer. The primary and secondary common windings are the transformation is fixed.Compared with the general transformer of the same capacity, it has the advantages of simple structure, less material consumption and small.Especially in the case where the transformation ratio is close to one, it is particularly economical.Therefore, this series is used more in high-power transmission transformers with similar voltages.In addition, it is widely used in the asynchronous voltage machine step-down starting box of 10KW or more.
