Abstract

The invention provides a winding method of a transformer coil. The winding method comprises the following steps of (A1) laying a grid-shaped insulating material which is distributed along the circumferential direction of a cylinder inner ring on the edge of the cylindrical inner ring, winding M turns of enamelled wires on the edge of the grid-shaped insulating material, winding (H-1) layers of enamelled wires on the basis of the method and arranging the grid-shaped insulating material between the adjacent layers of enamelled wires; (A2) coating the enamelled wires with insulating cloth during winding of the Hth layer and Mth turn of enamelled wire, thereby forming a first part with H layers and M turns of enamelled wires; and (A3) winding the enamelled wires coated with the insulating cloth on the edge of the grid-shaped insulating material of a second part and winding the coil with N parts by using the methods in the steps (A1) to (A2). The winding has the advantages that the cost is low and the working performance of a transformer is good.

Description

technical field [0001] The invention relates to a transformer, in particular to a winding method of a transformer coil. Background technique [0002] Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage used at all levels to meet the needs of power consumption. [0003] A power transformer includes an iron core and its outer low-voltage coils and high-voltage coils. Due to human factors in the winding process, the inner and outer sides of the wound coil are not standard arcs or planes, which need to be corrected to improve work performance. The usual practice is to use a hammer to hit the outer coils to make them meet the requirements. This method has disadvantages: [0004] 1. The forming effect is poor, even if it is corrected, it is difficult to meet the requirem...
