Auto auto regulator voltage regulator Three-phase auto voltage regulator contact 
 Autotransformer (auto-transformer) is only one winding of the transformer, when used as a step-down transformer, winding out from the part of 

 Turns as the secondary winding; When used as a step-up transformer, only added to the applied voltage winding - some of the turns on. Usually belong to one and two 

 Times as common winding part winding, as the rest of the series winding, with the capacity of self-coupling transformer transformer compared with the general, not only small size, 

 And efficient, and the greater capacity of the transformer, the higher the voltage. This advantage will become even more prominent. Thus, as the development of power systems, voltage references to 

 High and the transmission capacity increases, the self-coupling transformer due to its large capacity, low loss, low cost and widely used. 

 Autotransformer advantages and disadvantages: 

 Auto-transformer advantages: two windings overlap, so you can save some of the copper wire, smaller size, the structure is relatively simple. 

 Autotransformer shortcomings: between the primary and the secondary windings can not be completely isolated. In the step-down circuit, if the secondary winding is disconnected by accident, 

 The output voltage will rise as high and elementary, dangerous. 

 The company's transformer design, production more than 10 years of history, suitable for AC 50Hz to 400Hz, the following circuit voltage 1000V. 

 Widely used for transmission purposes or for adjustable output voltage power supply used. Such as lighting, electrical machines, machinery and electronic equipment, medical equipment, rectifier devices. Performance can meet the user to a variety of special
