Description

Technical Field

[0001] The invention relates to a protective cover for a multi-coil dry-type air-core reactor, belonging to the technical field of dry-type air-core reactors. Background Art

[0002] At present, the dry-type air-core reactors used in substations are usually placed in outdoor environments. Due to the lack of shelter and poor air quality, impurities and other pollutants will accumulate on the surface of the reactors. At the same time, rain will also cause corrosion to the reactors themselves. In addition, there is the possibility of birds building nests in the outdoor environment, which will affect the safe operation of the dry-type air-core reactors. In order to solve these problems, at present, a protective cover is usually added to the periphery of the dry-type air-core reactor to overcome the above problems.

[0003] However, there are also certain problems with adding a protective cover. First, simply using an integrated cover will affect the heat dissipation of the dry-type air-core reactor, which will bring safety hazards. In addition, the top and side of the protective cover address different problems. For example, the top needs to take into account corrosion protection and heat dissipation, while the side is mainly to prevent birds from nesting. Therefore, the degree of loss will be different, which will not be conducive to replacement and maintenance. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a protective cover for a multi-coil dry-type air-core reactor, which is used to provide effective protection while being easy to repair and replace.

[0005] In order to achieve the above object, the present invention provides a protective cover for a multi-coil dry-type air-core reactor, characterized in that it comprises:

[0006] The waterproof cover body comprises a plurality of separate rain caps, wherein first joint portions are arranged on both sides of the rain caps, and a first fixing strip is arranged on the top of the rain caps;

[0007] The bird-proof cover comprises a plurality of separate bird-proof nets, wherein the bird-proof nets are provided with grid parts, second splicing parts are arranged on both sides of the bird-proof nets, and a second fixing strip is arranged at the bottom of the bird-proof nets.

[0008] Furthermore, the waterproof cover is fixed to the top coil of the dry-type air-core reactor through the first fixing bar.

[0009] Furthermore, the bird-proof cover is fixed to the bottom coil of the dry-type air-core reactor through the second fixing bar.

[0010] Furthermore, the first splicing portion is provided with a via hole;

[0011] The adjacent rainproof caps are connected by bolts through the through holes.

[0012] Further, the rain cap includes an integrally formed inclined portion and a vertical portion;

[0013] The inclined portion is used for pouring rainwater, and the vertical portion is used for preventing rainwater from flowing out of the rainproof cap.

[0014] Furthermore, fixing protrusions for positioning are respectively provided at both ends of the first fixing strip.

[0015] Furthermore, the bottom of the vertical portion is connected with a trimming edge.

[0016] Furthermore, the second joint portion is provided with the through hole, and the adjacent bird-proof nets are connected by the bolts through the through hole.

[0017] Furthermore, the outer diameter of the rainproof cover is greater than the outer diameter of the bird-proof cover.

[0018] Furthermore, the waterproof cover and the bird-proof cover are made of fiberglass.

[0019] By adopting the above technical scheme, the present invention proposes a protective cover for a multi-coil dry-type air-core reactor, in which a waterproof cover body and a bird-proof cover body are separately fixed on two coils of the dry-type air-core reactor, wherein the waterproof cover body and the bird-proof cover body are both composed of multiple components assembled, thereby facilitating replacement and maintenance while ensuring the basic functions of heat dissipation and corrosion resistance.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below through the accompanying drawings and specific implementation methods. The dry-type air-core reactor currently used in the substation may be corroded by pollutants and rainwater because it is placed in an outdoor environment, and there is also a risk of birds nesting in the outdoor environment. Therefore, an integrated protective cover is often used to prevent the above situation from happening, but the integrated protective cover is not conducive to heat dissipation, and is also not conducive to replacement and maintenance. Therefore, a protective cover that can fully protect and facilitate replacement is needed.

[0025] Example

[0026] like Figures 1 to 3 As shown, the present invention provides a protective cover for a multi-coil dry-type air-core reactor, comprising:

[0027] The waterproof cover body 1 includes a plurality of separate rain caps 2, wherein first joint portions 3 are provided on both sides of the rain caps 2, and a first fixing strip 4 is provided on the top of the rain caps 2; the rain caps 2 include an integrally formed inclined portion 10 and a vertical portion 11;

[0028] The inclined portion 10 is used for guiding flow, and the vertical portion 11 is used for allowing rainwater to flow out of the rain cap 2 .

[0029] Preferably, the first joint portion 3 is provided with a through hole; and the adjacent rain caps 2 are connected by bolts through the through hole.

[0030] The waterproof cover 1 is fixed to the top coil of the dry-type air-core reactor through the first fixing bar 4. The first fixing bar 4 is provided with fixing protrusions 12 for positioning at both ends. In the actual fixing process, the fixing protrusions 12 can be connected with the positioning protrusions of the first fixing bar 4 on the adjacent rain cap 2, thereby further improving the overall fixing effect.

[0031] It should be added here that a trimming 13 is connected to the bottom of the vertical portion 11, and the function of the trimming 13 is to prevent rainwater from flowing into the coil inside the bird-proof cover 5 during falling.

[0032] The bird-proof cover 5 includes a plurality of separate bird-proof nets 6, the bird-proof nets 6 are provided with a mesh portion 7, the two sides of the bird-proof nets 6 are provided with a second splicing portion 8, and the bottom of the bird-proof nets 6 is provided with a second fixing bar 9. The bird-proof cover 5 is fixed to the bottom coil of the dry-type air-core reactor through the second fixing bar 9. It should be noted here that the waterproof cover 1 and the bird-proof cover 5 are installed separately, so as to effectively avoid the phenomenon of creepage between the upper and lower coils of the dry-type air-core reactor.

[0033] The second joint part 8 is provided with the through hole, and the adjacent bird-proof nets 6 are connected by the bolts through the through hole. The second joint part 8 is used to fix the adjacent bird-proof nets 6, similar to the function of the first joint part 3. The outer diameter of the rain cover in a preferred embodiment is greater than the outer diameter of the bird-proof cover 5; the function is the same as that of the aforementioned edge trimming 13, which prevents rainwater from falling into the coil inside the bird-proof cover 5.

[0034] In order to reduce the pressure on the dry-type air-core reactor caused by the protective cover when it is fixed, the waterproof cover 1 and the bird-proof cover 5 are made of fiberglass. At the same time, since fiberglass is non-magnetic, it will not increase additional losses, thereby ensuring the normal operation of the dry-type air-core reactor.

[0035] The present invention proposes a protective cover for a multi-coil dry-type air-core reactor, wherein a waterproof cover body and a bird-proof cover body are separately fixed on two coils of the dry-type air-core reactor, wherein the waterproof cover body and the bird-proof cover body are both composed of a plurality of components assembled, thereby facilitating replacement and maintenance while ensuring the basic functions of heat dissipation and corrosion resistance.

[0036] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
