Wire harness assembly for wind turbine generator and preparation method of wire harness assembly

Abstract

The embodiment of the invention discloses a wire harness assembly for a wind turbine generator and a preparation method. The wire harness assembly comprises an anti-torsion cable structure, a separable plugging structure and a grounding terminal, wherein the anti-torsion cable structure comprises a cable outer sheath, at least one grounding wire core and at least one main wire core, the grounding wire core comprises a first grounding wire core branch part and a second grounding wire core branch part which are connected with each other, and the main wire core comprises a first main wire core branch part and a second main wire core branch part which are connected with each other; the separable plugging structure comprises a wiring terminal, a cable adapter tube and a separable plugging structure main body; and the grounding terminal is crimped on one side, far away from the first grounding wire core branch part, of the second grounding wire core branch part. By adopting the wire harness assembly for the wind turbine generator, the matched use of the cable and the cable terminal accessory is realized, and the stable performance of the wire harness assembly for the wind turbine generator is effectively ensured.

Description

technical field [0001] The embodiments of the present invention relate to the field of cable technology, and in particular to a wire harness assembly for a wind turbine and a preparation method thereof. Background technique [0002] As an environmentally friendly power generation project, wind power has been vigorously promoted and used in recent years. The realization of wind power generation requires a lot of infrastructure construction in the early stage, including the investment of wind turbines. As an indispensable component in the application of wind power generation - wind power cables, the supporting usage has been fully promoted and used with the continuous development of wind power generation projects. [0003] At present, most suppliers in the industry deliver products to complete wind turbine manufacturers by separately supplying wind energy medium-voltage torsion-resistant cables and cable terminal accessories, and making and installing cable assemblies at the w...

AI Technical Summary

Problems solved by technology

[0004] (1) Wind energy medium-voltage torsion-resistant cables and T-shaped terminal joints are assembled at the project site. The working conditions on the site are harsh, especially the high humidity in the sea environment and the strong corrosion of salt spray, which cause objective conditions to affect the production of medium-voltage wiring harness components. , it is very easy to cause the operation failure of the medium voltage cable assembly

[0005] (2) The work of assembling medium-voltage wiring harness components on the project site is generally completed by the third-party construction team found by the owner or the wind turbine supplier. The production level of this construction team is uneven and there is no standardized operation. process, it is very easy to cause errors in the production of medium-voltage cable harness components or the production effect cannot meet the process requirements of the product, and the cable joints will fail and the joints will explode.

[0006] (3) In the production of such medium-voltage harness components on site, even after the components are manufactured, there is no systematic finished product test, that is, the pressure test and partial discharge test of the medium-voltage harness components, so that the electrical safety performance of the harness components cannot be guaranteed.
