Iron core material using imported grain oriented silicon steel sheet 45 degrees diagonal joints without punching the structure, the coil uses a high-strength oxygen-free copper polyethylene alcohol soluble enameled wire winding and into a cylindrical structure. Low-voltage side double winding structure and respectively for the transformer rated series of single-phase column distribution transformer is according to the S standard design and production, from the transformer itself loss than the current operation of the S series of three-phase power transformer more advanced, its transformer body is small and light, column hanging, easy to install at the same time to reduce the cost of the station. Column distribution transformer parameters capacity no-load loss load loss no-load current impedance voltage, the implementation of the example of Fushun Qingyuan County is located in the northern part of Liaoning Province, due to the power supply radius far beyond the allowable power supply radius, the voltage loss is serious, the loss of electrical energy, especially the peak stage of the voltage loss rate of up to 30 or so, the tail end of the user fluorescent lamps can not be activated, the TV set without images, etc., seriously affecting the quality of residential users of electricity. Power loss rate of up to 40, resulting in high electricity prices, the heavy burden on farmers, seriously dampening the enthusiasm of farmers to use electricity. Analysis of the power supply area shows that the transformer is always in light load operation, max load ratio is less than 40, using single-phase three-wire system to both sides of the power supply, the load is evenly distributed. Comparison of monthly power loss before and after transformation. Transformer monthly loss power consumption line monthly loss power consumption after transformation network loss reduction rate before transformation after transformation, comprehensive benefit analysis: in the same capacity under no-load loss decreased significantly. With single-phase transformer power supply, the high-voltage line can be set up according to two lines, and the low-voltage line can be set up according to two or three lines, while with three-phase distribution transformer power supply, the high-voltage line must be set up according to three lines, and the low-voltage line is set up according to four lines.
