Electrical wiring method of multistage variable-capacity power equipment

The invention discloses an electrical wiring method of multistage variable-capacity power equipment. A plurality of coils are arranged in the power equipment, each coil adopts a multi-outlet head, multi-contact switching of an on-load capacitance-regulating and voltage-regulating switch is adopted, and structural series-parallel connection switching combination is carried out on the coil accordingto an electrical load. The internal current and the coil turn number distribution are automatically adjusted and changed, the multi-stage excitation of the iron core is realized, the multi-capacity variable output of the power equipment is further realized, the corresponding no-load loss and load loss are realized under each capacity, and the high-efficiency output of the power equipment under different load conditions is realized. According to the electrical wiring method of the multistage variable-capacity power equipment, the capacity output of the transformer is automatically adjusted through the on-load capacity
