Internal-winding-heating vacuum and vacuum pressure paint immersion equipment

Abstract

The invention discloses internal-winding-heating vacuum and vacuum pressure paint immersion equipment applicable to winding paint immersion insulation treatment of electrical equipment of various lowvoltage motors, high voltage motors, new energy vehicle motors, transformers, mutual inductors and the like with an aim to solve problems that current domestic winding insulation treatment equipment adopts oven or oven tunnel heating resulting in poor permeability of winding, less paint for insulation treatment, high energy consumption and the like while common internal heating paint immersion equipment widely adopted abroad is low in production efficiency, poor in security and the like. The vacuum and vacuum pressure paint immersion equipment is characterized in that an internal winding heating technology is adopted during paint immersion, special direct-current power supply is used, the winding is charged with large direct current, winding temperature is raised, and insulation paint is cured; compared with the equipment using the oven or oven tunnel heating method, the vacuum and vacuum pressure paint immersion equipment has the advantages that paint adherence is highly increased, loss of the insulation paint is remarkably reduced, the permeability is improved, and energy consumption is reduced; compared with the common internal winding heating method, the internal-winding-heating vacuum and vacuum pressure paint immersion equipment is high in permeability and production and safe and reliable.

Description

technical field [0001] Various types of low-voltage motors, servo motors, high-voltage motors, new energy vehicle motors, transformers, transformers and other electrical equipment winding varnish insulation treatment equipment. Background technique [0002] At present, domestic winding insulation treatment equipment mainly includes dripping paint insulation treatment equipment, ordinary immersion equipment, tank vacuum impregnation equipment, tank vacuum pressure impregnation equipment, continuous immersion equipment, continuous vacuum impregnation equipment, etc., such equipment The pre-baking before dipping of the winding and the solidification after dipping are all heated by an oven or a drying tunnel. This type of insulation treatment equipment has disadvantages such as poor winding permeability, less paint hanging on insulation treatment, more paint loss, and large energy loss. There are relatively advanced insulation treatment equipment in foreign countries, which use...

AI Technical Summary

Problems solved by technology

In-winding heating immersion equipment and winding heating dripping equipment have problems such as poor penetration of immersion paint, easy existence of air bubbles, low production efficiency, and not suitable for mass production.

In addition, since the winding is heated by direct current, if the operation is improper, it is easy to be cremated due to current discharge, causing the insulating varnish to catch fire. When the temperature is about 100 degrees, there is a great potential safety hazard when encountering an open flame
