Embodiment 1

[0023] A high-voltage motor magnetic pole coil turn-to-turn insulation processing method, which is characterized by: including the following process, numbering and marking the paired magnetic pole cores and magnetic pole coils, disassembling, annealing, cleaning, forming, flat winding, and Turn-connection, insulation blanking, inter-turn insulation process to realize the inter-turn insulation of the magnetic pole coil, and set it with the magnetic pole core according to the number.

[0024] When numbering and marking the magnetic pole coils, after increasing the number of turns of the copper bar and marking the position of the original lead wire, the number of turns of the copper bar is welded to ensure that the position and size of the original lead wire remain unchanged.

[0025] When the pole coil is formed, the insulation of the pole body of the pole coil and the heat-pressing structure of the pole support plate are adopted to ensure the heat-pressing quality of the pole co...

Abstract

The invention relates to a processing method for interturn insulation of a high-voltage motor pole coil, belonging to the technical field of motors. The processing method for interturn insulation of the high-voltage motor pole coil is characterized by comprising the following technical processes: numbering and marking paired pole core and pole coil, and conducting procedures of dismantling, annealing, cleaning, forming, edgewise winding, turn connection, insulated blanking and pad interturn insulation to the pole coil, so as to realize interturn insulation of the pole coil, and lead the pole coil to be sheathed with the pole core according to a number. The method has the advantages of simple technology, good heat dissipation effect, stable electrical performance, high heat-resisting class, capability of avoiding turn-to-turn short circuit of the pole coil, reduction of manufacturing cost for machine set transformation, and reduction of raw material consumption and the like.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a processing method for inter-turn insulation of a magnetic pole coil of a high-voltage motor. Background technique [0002] At present, due to the long running time and the carbonization of the inter-turn insulation of the magnetic pole coil, the turn-to-turn short circuit of the magnetic pole coil, the rotor overcurrent and the reduction of reactive power output are caused by the high-voltage motor capacity expansion and transformation unit. The unit is scrapped, and the magnetic pole coil needs to be replaced with a new type of inter-turn insulation. The turn-to-turn insulation structure used in the magnetic pole coil before the transformation had low heat resistance grade, thick turn-to-turn insulation, raw material consumption, poor heat dissipation effect, large motor volume, low unit capacity, and high cost. Contents of the invention [0003] The invention pr...
