Embodiment Construction

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0017] The invention discloses a production method of a pitch-variable electrical slip ring for a wind power generator, such as figure 1 As shown, the method may include the following steps:

[0018] Step S101, fixing the steel mandrel and each copper ring through a mould;

[0019] In the embodiment of the present invention, firstly, the steel mandrel and each copper ring are fixed through a mold, wherein the steel mandrel is made of steel, so the rigidity of the slip ring can be enhanced. Each copper ring can be used for the transmission of commu...

Abstract

The invention provides a method for producing the variable-pitch electrical slip ring of the wind turbine, comprising the following steps: step A, fixing a steel core shaft and copper rings through a mould; step B, carrying out high temperature-resistant treatment on a cable, and leading the cable after high temperature-resistant treatment out of the copper rings of the mould; and step C, filling gaps with insulating materials, and carrying out integrated die-casting molding. According to the invention, the cable and the copper rings are welded together through high-temperature silver soldering, so that the technical problem that a cable and a copper ring cannot be welded together is solved. Through the integrated die-casting molding process, the slip ring has strong overall sealing performance and has the characteristics of being anti-jamming, moisture-proof, shock-proof, resistant to mold, high in concentricity and the like.

Description

technical field [0001] The invention relates to the technical field of electrical slip rings, in particular to a production method for pitch-variable electrical slip rings used in wind power generators. Background technique [0002] At present, the pitch electrical slip rings used in wind farms are all assembled structures. As the name suggests, the assembled structure is assembled from multiple parts. Therefore, the product density is not real, and there are gaps between parts. Or used in harsh environments, it is easy to be attacked by moisture, which will cause problems such as electric leakage and unstable signal transmission, and may easily cause faults such as signal flashing. In addition, the concentricity of the assembled structure is difficult to guarantee, which will cause the product to jump during use and cause electrical sparks and other failures. Contents of the invention [0003] The purpose of the present invention is to provide a production method for a p...
