Description

Technical Field

[0001] The utility model belongs to the technical field of anti - bird covers for reactors, and particularly relates to an anti - bird cover for dry - type air - core reactors. Background Technique

[0002] Air - core reactors are inductive high - voltage electrical appliances used in power systems to limit short - circuit current, reactive power compensation, phase shifting, etc. The magnetic flux forms a loop through air, so it is called an air - core reactor. Among them, dry - type air - core reactors are commonly used electrical equipment in outdoor power plants and substations, and their main functions are to limit the short - circuit current of the bus or outgoing line and maintain the reactive power balance of the system.

[0003] The bare installation of air - core reactors easily allows birds to build nests in them, thus endangering the operation of the reactors. Therefore, anti - bird covers are generally installed on the reactors. In order to facilitate the passing of wires, existing anti - bird covers generally have wiring ports reserved. However, for the convenience of wire threading, the existing wiring ports are generally relatively large. After the wire passes through the wiring port, there is still a relatively large gap between the wire and the wiring port, allowing birds to drill into the anti - bird cover through the gap, thus affecting the overall anti - bird effect. Therefore, it is urgent to design an anti - bird cover with better anti - bird effect. Content of the Utility Model

[0004] In view of the problems existing in the above - mentioned prior art, the utility model discloses an anti - bird cover for dry - type air - core reactors, and specifically discloses the following technical solutions:

The rain - proof cover is fixedly connected to the star - shaped arm on the top of the reactor through a plurality of support members. The anti - bird grille covers the periphery of the top of the reactor. A wiring port is opened at a position corresponding to the wiring arm of the reactor on the side of the anti - bird grille, and a mesh cloth is fixedly connected at the wiring port.

[0006] Further, the anti - bird grille is a closed - loop structure formed by splicing a plurality of unit grilles end to end, and adjacent unit grilles are fixedly connected by bolts.

[0007] Further, each unit grille includes an arc - shaped side grille and a bottom grille fixedly connected to the inner side of the bottom of the side grille. The top of the side grille is fixedly connected to the edge of the rain - proof cover by bolts. A plurality of bottom grilles are spliced into a closed ring - shaped structure, and one end of the bottom grille away from the side grille abuts against the outer wall of the reactor.

[0008] Further, each unit grille is an arc - shaped structure. The bottom of the unit grille is fixedly connected to the star - shaped arm through a grille support, and the top of the unit grille abuts against the lower surface of the rain - proof cover.

[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1

[0026] Refer to Figures 1-6 , a bird-proof cover for a dry-type air-core reactor, which includes a rain-proof cover 1, a bird-proof grille, and a support member 2. The rain-proof cover 1 is fixedly connected to the star frame arm 4 at the top of the reactor 3 through a plurality of support members 2. The bird-proof grille covers the periphery of the top of the reactor 3. A wiring port is provided at a position on the side of the bird-proof grille corresponding to the wiring arm 8 at the top of the reactor 3. A mesh cloth 5 is fixedly connected at the wiring port. When there is a need for wire threading at the wiring port, corresponding through holes can be opened on the mesh cloth 5 according to the actual number and size of the wires, so as to ensure that the wires can just pass through the mesh cloth 5 and are closely attached to each other, thereby effectively improving the bird-proof effect.

[0027] In this embodiment, the bird-proof grille is a closed-loop structure formed by splicing a plurality of unit grilles 6 end to end. Adjacent unit grilles 6 are fixedly connected by bolts, which is convenient for assembly and disassembly.

[0028] In this embodiment, the bolts connecting adjacent two unit grilles 6 are made of nylon material. When the voltage level of the reactor is relatively high, the nylon bolts can avoid floating potential.

[0029] In this embodiment, the unit grille 6 includes an arc-shaped side grille and a bottom grille fixedly connected to the inner side of the bottom of the side grille. The top of the side grille is fixedly connected to the edge of the rain-proof cover 1 by bolts. A plurality of bottom grilles are spliced into a closed ring structure. One end of the bottom grille away from the side grille abuts against the outer wall of the reactor 3.

[0030] Since the side grille in this embodiment is connected to the edge of the rain-proof cover 1, and the maximum diameter of the rain-proof cover 1 is greater than the diameter of the reactor 3, there is a certain gap between the bottom of the side grille and the side wall of the reactor 3. The function of the bottom grille is to block the gap between the bottom of the side grille and the reactor 3, so as to prevent birds from flying into the reactor 3 from the bottom gap.

[0031] In this embodiment, the bottom of the support member 2 is fixedly connected to the star frame arm 4 by bolts, and the top of the support member 2 is fixedly connected to the rain-proof cover 1 by bolts.

[0032] In this embodiment, an installation opening is provided through the top of the rain shield 1, and a rainproof grille 7 is installed in the installation opening.

[0033] Embodiment 2

[0034] Referring to Figures 7-10 , the solution of this embodiment is basically the same as that of Embodiment 1. The only difference is that the cell grille 6 in this embodiment is an arc structure. The bottom of the cell grille 6 is directly fixedly connected to the star arm 4 through a grille bracket 9, and the top end of the cell grille 6 abuts against the lower surface of the rain shield 1. In this embodiment, the bottom of the cell grille 6 is directly in contact with the side wall of the reactor 3, and the top of the cell grille 6 is directly in contact with the lower surface of the rain shield 1, which can also achieve a reliable anti-bird effect.

[0035] The above are only preferred embodiments of the present invention, and do not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
