Thermocompression processing method for quadrangle welding magnetic pole coil

Abstract

The invention relates to a thermocompression processing method for a quadrangle welding magnetic pole coil, belonging to the technical field of generators. The thermocompression processing method for a quadrangle welding magnetic pole coil comprises the step of placing an interturn insulator on the quadrangle welding magnetic pole coil and is characterized by comprising the following steps: firstly, hoisting coil side press tool equipment on an oil press; placing the quadrangle welding magnetic pole coil provided with the interturn insulator into the side press tool equipment; sequentially placing diselectric paper and a hot-press film at the inner diameter of the quadrangle welding magnetic pole coil; when gluing paper is placed, overlapping two layers in a staggered way; fixing the gluing paper by a double sticky tape; clamping the lead position of the magnetic pole coil and a control cabinet conducting clamp of a direct current machine; and then heating to carry out thermocompression molding processing. The invention has the advantages of simple process, high insulation heat resistant grade, raw material saving, time and power saving processing, low cost of the whole machine unit, attractive appearance, favorable heat dissipation effect and electric performance, and the like and can prevent phenomena of poor sticking, looseness and a short circuit.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a hot-pressing processing method for four-corner welding magnetic pole coils. Background technique [0002] At present, during the hot-pressing process of the four-corner welding magnetic pole coil, due to factors such as the use of new materials for inter-turn insulation, improper process temperature and parameter selection, poor bonding of copper bars and (Nomex) adhesive tape, open-turn phenomena, and open-turn phenomena are likely to occur. If the adhesive tape is not evenly pasted, it is easy to cause the two layers of adhesive tape to overlap the four corners of the magnetic pole coil, the height and dimension are out of tolerance, and the inter-turn short circuit phenomenon will affect the electrical performance and insulation quality of the magnetic pole coil. During the hot pressing process, before installing the hot pressing mold, the inner diameter of th...

[0002] At present, during the hot-pressing process of the four-corner welding magnetic pole coil, due to factors such as the use of new materials for inter-turn insulation, improper process temperature and parameter selection, poor bonding of copper bars and (Nomex) adhesive tape, open-turn phenomena, and open-turn phenomena are likely to occur. If the adhesive tape is unevenly pasted, it is easy to cause two layers of adhesive tape to overlap the four corners of the magnetic pole coil, the height and dimension are out of tolerance, and the short circuit between turns will affect the electrical performance and insulation quality of the magnetic pole coil.

During the hot pressing process, before installing the hot pressing mold, the inner diameter of the magnetic pole coil needs to be padded with polyester film and insulating paper for electrical insulation. After the hot pressing process is completed, the inner diameter of the magnetic pole coil should be filled with polyester film and The electric insulation paper is scrapped immediately, resulting in large material consumption and increased motor production costs, etc.
