Elevator Parts - autotransformer

Autotransformer structure is characterized by low-voltage winding is coupled between the magnetic part of the existing high-voltage winding , high and low voltage windings , another electrical contact . Compared with the same capacity two-winding transformer , autotransformer advantage is saving material , high efficiency. When a ratio closer to 1 , the winding ( design ) capacity of the smaller , more prominent advantages. It is suitable for making contact transformer is used to connect two voltage levels similar to the grid ; regulator can also be used as in the laboratory ; or autotransformer achieve asynchronous motor voltage starting .

The power delivered by the auto-transformer consisting of two parts : a part of the electromagnetic power by electromagnetic induction from the primary side to the secondary side load transfer , which is the output power of the times ; another part is conducted power directly from the power delivered by the series winding to the secondary side load , which is 1-1/K2 times the output power . Autotransformer design capacity is smaller than the rated capacity because the design capacity is winding capacity , which corresponds to electromagnetic capacity, only rated capacity 1-1/K2, so the design capacity is smaller than the rated capacity.
