Description

Technical Field

[0001] This utility model relates to a top cap for an air-core reactor, belonging to the field of reactor technology. Background Technology

[0002] With the development of my country's power industry, more and more substations are using power cables for their incoming and outgoing lines. The capacitive current generated by these cables can affect power quality. Therefore, more and more substations are using reactors (such as air-core reactors) to compensate for the capacitive current generated by the cables, thereby improving power quality. Since reactors are installed outdoors, during operation, extreme weather conditions such as high temperatures and heavy rain can easily cause rainwater to enter the reactor, leading to reactor burnout.

[0003] To address the problem that reactors lack protective devices and are thus damaged in severe weather, the current approach is mostly to add rainproof caps. However, this method cannot simultaneously address the issues of rain protection and effective heat dissipation. Therefore, a protective device that can meet the requirements of high-temperature heat dissipation and rain and water protection for reactors is needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a top cap for an air-core reactor to meet the usage requirements of the air-core reactor in terms of heat dissipation and rain protection.

[0005] To achieve the above objectives, this utility model provides a top cap for an air-core reactor, comprising:

[0006] The top cover includes an arc-shaped top and an edge portion fixedly connected to the arc-shaped top;

[0007] At least two rainproof grilles are spliced ​​into a cylindrical shape and fixedly connected to the edge portion; the rainproof grilles have multiple window holes parallel to the edge portion.

[0008] Furthermore, the top cover and the rainproof grille are made of fiberglass with a thickness of 5-8mm.

[0009] Furthermore, a first mounting hole is provided on the edge portion.

[0010] Furthermore, the number of rainproof grilles is four, and the curvature of the rainproof grilles is 90°.

[0011] Furthermore, the edge of the rainproof grille is fixed with horizontal and vertical tie rods;

[0012] The vertical tie rod is provided with a second mounting hole for connecting the rainproof grilles to each other;

[0013] The horizontal tie rod has the first mounting hole.

[0014] Furthermore, the window opening is fitted with louvers;

[0015] The louver includes a downward-opening outer edge, the width of which is 30mm;

[0016] The angle of the outer edge is -9°.

[0017] Furthermore, the rainproof grille is fixed to the star-shaped arm to which the hollow reactor belongs via the second mounting hole.

[0018] By adopting the above technical solution, the top cap for an air-core reactor provided in this utility model embodiment uses a separate top cover and multiple rainproof grille structures. After the multiple rainproof grilles are spliced ​​into a cylindrical shape, they are fixedly connected to the multiple rainproof grilles through the edge of the top cover. The air-core reactor is cooled by the windows on the rainproof grilles, and the rainproof requirements are also met, thus taking into account multiple usage scenarios of the air-core reactor.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Existing reactors are installed outdoors. Due to the lack of protective devices, during operation, high temperatures, heavy rain, and other severe weather conditions can easily cause the reactor to overheat or allow rainwater to enter, leading to reactor burnout. Therefore, existing air-core reactors need a protective device that combines high-temperature heat dissipation with rain and water protection.

[0024] Example

[0025] like Figures 1 to 3 As shown, this utility model provides a top cap for an air-core reactor, comprising:

[0026] The top cover 1 includes an arc-shaped top 2 and an edge portion 3 fixedly connected to the arc-shaped top 2; in a preferred embodiment, the edge portion 3 may be a pressure equalizing ring for averaging the pressure of the top cover 1.

[0027] At least two rainproof grilles 4 are spliced ​​into a cylindrical shape and fixedly connected to the edge portion 3; the rainproof grilles 4 have a plurality of window holes 5 parallel to the edge portion 3.

[0028] The top cover 1 and the rainproof grille 4 are made of fiberglass with a thickness of 5-8mm. Fiberglass has the advantages of being sturdy and durable, having high strength and rigidity, and being easy to manufacture, which can improve the reliability of the top cover.

[0029] The edge portion 3 has a first mounting hole. The edge of the rainproof grille 4 is fixed with a horizontal tie rod 6 and a vertical tie rod 7; wherein the vertical tie rod 7 is attached to the edge of the side of the rainproof grille 4; the horizontal tie rod 6 is attached to the top and bottom edges of the rainproof grille 4;

[0030] The vertical tie rod 7 has a second mounting hole for connecting the rainproof grilles 4 to each other; in specific use, the rainproof grilles 4 can be fixedly connected to the hollow reactor through the second mounting hole, thereby forming an integral structure with the hollow reactor.

[0031] The horizontal tie rod 6 has the first mounting hole.

[0032] In a preferred embodiment, four rainproof grilles 4 are used, and the arc of each rainproof grille 4 is 90°. Second mounting holes are provided on the vertical tie rods 7, and adjacent rainproof grilles 4 are fixed together with bolts to form a cylindrical shape. Furthermore, the top cover 1 and the rainproof grilles can be fixed together with bolts using the first mounting holes provided on the edge portion 3 and the horizontal tie rods 6.

[0033] To improve the rainproof effect of the top cap, a louver 8 is installed in the window opening 5. The louver 8 includes a downward-opening outer edge with a width of 30mm.

[0034] The angle of the outer edge is -9°. It should be noted that the angle of the outer edge is calculated based on the included angle between the two sides of the outer edge's length and the height of the inner side of the louver 8, and includes, but is not limited to, -9°. Due to the downward-facing opening design, rainwater is prevented from entering the interior of the hollow reactor through the top cap, while also ensuring adequate heat dissipation.

[0035] The present invention provides a top cap for an air-core reactor, which employs a separate top cover and multiple rainproof grille structures. After the multiple rainproof grilles are spliced ​​into a cylindrical shape, they are fixedly connected to the multiple rainproof grilles through the edge of the top cover. The air-core reactor is cooled by the windows on the rainproof grilles, and the rainproof requirements are also met, thus taking into account multiple usage requirements of the air-core reactor.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
