Background
When the number of turns between the tapping wires of the tapping section of the coil in which a plurality of wires are wound in parallel is small, if a continuous coil structure is adopted, two tapping wires are usually required to be led out from the top and the bottom of one wire cake, and the structure can cause inter-strand circulating current due to different lengths of the wires connected in parallel between the two tapping wires and different passing magnetic fluxes, so that the product loss is excessive, the coil wires are heated, and the coil can be burnt under severe conditions.
In order to solve the problem of circular current between the tapping section and the parallel winding wire strand of the continuous coil, the tapping section generally adopts a knotting structure, the knotting structure can lead the tapping wire out of the surface of the tapping section, and the knotting structure has strong current impact resistance and can prolong the service life of the coil. However, when the number of parallel windings of the coil is large (4 or more) and the number of turns between the tapping lines is small (less than 3 turns), the conventional entanglement structure causes great radial height difference of the tapping sections, which usually differs by the thickness of one turn of lead, if the lead is higher than the oil gap cushion block, the lead is not easy to be fixed, and the coil is easy to be deformed unstably when being impacted by large current, and is burnt out seriously.
