Single-section extraction method of tap joints of continuous high-voltage coils of transformer

The invention discloses a single-section extraction method of tap joints of continuous high-voltage coils of a transformer. The tap section of each coil comprises a tangling section, a left rotating normal section and a right rotating normal section, wherein each section is led with a tap joint, and the section numbers of the tangling section, the left rotating normal section and the right rotating normal section and the turn number of the tangling section meet the requirement of the interval turn number of the tap joints. By adopting the single-section extraction method of tap joints of continuous high-voltage coils of the transformer, the tap sections of the high-voltage coils of the transformer occupies small space, well balances the ampere turns of the high voltage and the low voltage of the transformer, and can greatly reduce the material consumption, the loss and the production cost of the transformer.
