Abstract
The invention belongs to the technical field of transformers, and in particular relates to a method for interchanging windings by a single spiral mode of three parallel-connected lead wires of the transformer. By a method for performing twice position interchanging by dividing three lead wires into two groups, the leakage chains are the same. The method has the advantages that: the leakage chains generated by the windings of the transformer coiled by the method are the same, so the generated leakage reactance voltages are the same and the induced electromotive forces of leakage flux are the same; therefore, no circulating current exists among the three lead wires, so no additional loss is generated in the windings; moreover, as the temperature of the windings is constant, the energy is saved and the environment is protected, and the service life of the transformer is prolonged.
