Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, many gear regulating autotransformer principles:
Autotransformer exports and inputs the special transformer sharing one group of coil, and the different tap of voltage-regulation realizes, and when using as step-down transformer, extracts a part of wire turn out as secondary winding from winding.Usually once common winding is called with the part winding of secondary belonging to simultaneously, remainder is called series connection winding, with the single-circuit transformer of capacity compared with common transformer, not only size is little, and efficiency is high, loss is little, cost is low, and transformer capacity is larger, this advantage is just all the more outstanding.Demand when autotransformer coiling according to pressure regulation distributes multiple tap in secondary winding, and when input voltage is certain, the output voltage that different taps is corresponding different, realizes the pressure regulation of many gears and Energy Saving Control exports.
