Detailed Description
Specific embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 2. While specific embodiments of the disclosure are shown in the drawings, it should be understood that the disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
It should be noted that certain terms are used throughout the description and claims to refer to particular components. As one skilled in the art will appreciate, various names may be used to refer to a component. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The description which follows is a preferred embodiment of the invention, but is made for the purpose of illustrating the general principles of the invention and not for the purpose of limiting the scope of the invention. The scope of the present disclosure is to be determined by the terms of the appended claims.
To facilitate an understanding of the embodiments of the present disclosure, the following detailed description is to be considered in conjunction with the accompanying drawings, and the drawings are not to be construed as limiting the embodiments of the present disclosure.
In one embodiment, as shown in fig. 2, a salt fog resistant core grounding system for an offshore wind power transformer comprises: an epoxy resin sleeve 3, a cable joint 4 and a single-core flexible cable 5; the epoxy resin sleeve 3 is arranged on the transformer lifting seat 2, one end of the epoxy resin sleeve is connected with the transformer iron core 1 through an iron core grounding lead, the other end of the epoxy resin sleeve is connected with one end of a single-core flexible cable 5 through a cable joint 4, and the other end of the single-core flexible cable 5 is grounded.
In the embodiment, the epoxy resin sleeve is arranged outside the conductor, so that the problem of electrode exposure in the prior art can be solved; in addition, because the epoxy resin sleeve has extremely strong corrosion resistance, the conductor can be protected from salt fog erosion on the sea by installing the pluggable epoxy resin sleeve on the conductor and covering the crosslinked polyethylene for insulation.
In another embodiment, a round hole is formed in one end, connected with the transformer core, of the epoxy resin sleeve, and one end of the iron core grounding lead is connected with the epoxy resin sleeve through the round hole.
In the embodiment, the round hole of the epoxy resin sleeve is protected by the anti-loosening steel wire thread sleeve, so that the iron core grounding lead can be prevented from falling off due to the vibration of the transformer.
In another embodiment, the system further comprises a stainless steel clamping hoop, and the single-core flexible cable is fixed on the transformer oil tank through the stainless steel clamping hoop.
In another embodiment, the system further comprises a protection box, and the grounding end of the single-core flexible cable is protected by the protection box.
In this embodiment, the protection box is made of 316L stainless steel, and the 316L stainless steel metal piece has strong corrosion resistance and can be directly soaked in seawater without being corroded, so that the system can be ensured to reach the C5-M corrosion resistance level. According to ISO12944, the corrosion prevention grade of coastal and offshore areas with high salinity needs to reach CX (namely, the old standard C5-M grade), so that the installation and use requirements of offshore wind power can be met by adopting stainless steel.
The above-mentioned preferred embodiments, objects, technical solutions and advantages of the present invention are further described in detail, it should be understood that the above-mentioned are only preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included within the scope of the present invention.
