Problems solved by technology

[0003] The surface lubricity, softness and wear resistance of the enameled wire produced by the conventional method are poor. The insulating film is easy to be damaged. During the electrical performance test of the wound compressor coil, there will be inter-turn discharge, which will eventually cause the compressor to burn out due to a short circuit, which cannot meet the winding requirements of the DC inverter compressor coil.

Embodiment Construction

[0021] The production method of the DC frequency conversion enameled wire of the present invention is illustrated in conjunction with the accompanying drawings and embodiments

[0022] According to the performance requirements of the DC inverter compressor and the particularity of the winding method of the DC compressor coil, that is, the winding speed is fast, the copper wire is stretched, and the copper wire is scratched during the winding process. Some properties, such as the softness, surface lubricity and wear resistance of the enameled wire, have been improved to meet the special winding requirements of the enameled wire for DC inverter compressors.

[0023] In order to produce enameled wires that meet the needs of DC inverter compressor motors, a long period of exploration was carried out in the selection of raw materials and production processes, and after several rounds of PDCA cycle planning. Special requirements for the above three indicators of enameled wire, such ...

Abstract

The invention provides a method for producing a DC variable frequency enameled wire which is called as a DC enameled wire for short. The method comprises the steps: selection of raw materials and production process of the DC enameled wire: (1) drawing; (2) annealing; (3) painting; (4) detecting solidification degree. The invention has the advantages that compared with the conventional enameled wire, the DC enameled wire is greatly improved in the aspects such as flexibleness, surface lubricity and the like, and especially has good wearing resistance; when the DC enameled wire is used for winding on winding equipment, the outside film of the DC enameled wire is not easy to scratch by parts contacting with the film, so that the insulating property of a winding coil of a compressor can be ensured, and the phenomenon of interturn discharge breakdown can be avoided.

Description

technical field [0001] The invention relates to a production method for making a DC frequency conversion enameled wire suitable for a DC frequency conversion air conditioner compressor. Background technique [0002] In order to actively respond to the upgrade of air-conditioning energy efficiency standards, major air-conditioning companies have adjusted their product structure and launched energy-saving products. Frequency conversion is a good way to improve energy efficiency. Frequency conversion air conditioners will gradually replace fixed-frequency air conditioners. , constant temperature, quiet, wide range of applicable voltage and other advantages. In order to meet the needs of the frequency conversion air conditioner market, the compressor at the heart of the air conditioner will also be transformed from the traditional fixed frequency compressor to the frequency conversion compressor. The representative one is the DC frequency conversion compressor. The main feature ...
