Description

Technical Field

[0001] The invention relates to a top cap for an air-core reactor, belonging to the technical field of reactors. Background Art

[0002] With the development of my country's power industry, more and more substations use power cables for inlet and outlet lines. The capacitive current generated by the cable will affect the quality of the electric energy, so more and more substations use reactors (such as air-core reactors) to compensate for the capacitive current generated by the cable to improve the quality of the electric energy. Since the reactor is installed outdoors, during the specific operation process, due to high temperature, heavy rain and other bad weather, it is easy to cause rainwater to enter the reactor, which in turn causes the reactor to burn out.

[0003] In order to solve the problem that the above-mentioned reactor is damaged in bad weather due to lack of protection device, most of the methods currently adopted are to add rainproof top caps. However, this method cannot take into account the problems of rain protection and effective heat dissipation. Therefore, a protection device is needed that can meet the high-temperature heat dissipation of the reactor and rain and water protection. Summary of the invention

[0004] Therefore, an object of the present invention is to provide a top cap for an air-core reactor to meet the use requirements of the air-core reactor in a heat dissipation and rain protection state.

[0005] In order to achieve the above object, the present invention provides a top cap for an air-core reactor, comprising:

[0006] A top cover, comprising an arc top portion and an edge portion fixedly connected to the arc top portion;

[0007] At least two rainproof grilles are spliced ​​into a cylindrical shape and fixedly connected to the edge portion; the rainproof grille is provided with a plurality of window holes parallel to the edge portion.

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

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

[0010] Furthermore, the number of the rainproof grilles is 4, and the curvature of the rainproof grilles is 90°.

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

[0012] The vertical tie bars are provided with second mounting holes for connecting the rainproof grilles to each other;

[0013] The horizontal tie rod is provided with the first mounting hole.

[0014] Further, the window hole is equipped with a shutter;

[0015] The shutter comprises an outer edge opening downward, and the width of the outer edge is 30 mm;

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

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

[0018] By adopting the above technical scheme, a top cap for a hollow-core reactor provided in an embodiment of the present invention adopts a separate top cover and multiple rainproof grille structures, and after the multiple rainproof grilles are spliced ​​into a cylindrical shape, the edge of the top cover is fixedly connected to the multiple rainproof grilles, and the window holes on the rainproof grilles are used to dissipate heat from the hollow-core reactor, and the need for rain protection can also be met, thereby taking into account multiple usage scenarios of the hollow-core reactor.

[0023] The present invention is further described in detail below through the accompanying drawings and specific implementation methods. The existing reactor is installed outdoors. Due to the lack of a protective device, during the specific operation process, due to severe weather such as high temperature and heavy rain, it is easy to cause the reactor to overheat or rainwater to enter, thereby causing the reactor to burn out. Therefore, the existing air-core reactor needs a protective device that takes into account high-temperature heat dissipation and rain and water resistance.

[0024] Example

[0025] like Figures 1 to 3 As shown, the present invention provides a top cap for an air-core reactor, comprising:

[0026] The top cover 1 comprises an arc top portion 2 and an edge portion 3 fixedly connected to the arc top portion 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 grille 4 is provided with 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 5-8 mm. The fiberglass has the advantages of being strong and durable, having high strength, high rigidity and being easy to manufacture, and can improve the reliability of the top cap.

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

[0030] The vertical tie bars 7 are provided with second mounting holes for interconnecting the rain grilles 4; in specific use, the rain grilles 4 can be fixedly connected to the air-core reactor through the second mounting holes, thereby forming an integrated structure with the air-core reactor.

[0031] The horizontal tie rod 6 is provided with the first mounting hole.

[0032] In a preferred embodiment, the number of rain grilles 4 used is 4, and the curvature of the rain grilles 4 is 90°. A second mounting hole is provided on the vertical tie bar 7, and adjacent rain grilles 4 are fixed by bolts to form a cylindrical shape. Furthermore, the top cover 1 and the rain grilles can be fixed together by bolts through the first mounting holes respectively provided in the edge portion 3 and the horizontal tie bar 6;

[0033] In order to improve the rainproof effect of the top cap, the window hole 5 is installed with a shutter 8, and the shutter 8 includes an outer edge opening downward, and the width of the outer edge is 30mm;

[0034] The angle of the outer edge is -9°. It should be added that the angle of the outer edge is calculated based on the angle between the two sides of the measured length of the outer edge and the height of the inner side of the shutter 8, including but not limited to -9°. Due to the downward opening design, rainwater can be prevented from entering the interior of the air-core reactor through the top cap, and the heat dissipation needs are guaranteed.

[0035] A top cap for an air-core reactor provided in an embodiment of the present invention adopts a separate top cover and a plurality of rainproof grille structures, and after the plurality of rainproof grilles are spliced ​​into a cylindrical shape, the top cover is fixedly connected to the plurality of rainproof grilles through the edge of the top cover, and the window holes on the rainproof grilles are used to dissipate heat from the air-core reactor, and the need for rain protection can also be met, thereby taking into account multiple usage requirements of the air-core reactor.

[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.
