[0002] Outdoor high-voltage capacitors are capacitors used in high-voltage power systems. They are typically installed outdoors to improve the power factor and stability of the power system. Their main function is to compensate for the reactive power demand in the line by providing reactive power, thereby reducing energy loss and improving the efficiency of power transmission. They are commonly used in high-voltage transmission lines, substations, and some power facilities that require improved power quality.

[0003] However, most existing outdoor high-voltage capacitors are installed using multiple bolts, resulting in the need for a large number of bolts during installation and removal, leading to low practicality. Therefore, those skilled in the art have provided an outdoor high-voltage capacitor that offers high stability and ease of installation to address the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an outdoor high-voltage capacitor with high stability and easy installation, comprising: a high-voltage capacitor body and a box plate slidably installed on one side of the high-voltage capacitor body, a sealing plate fixed on one side of the box plate, a heat dissipation frame installed on the outside of the sealing plate, a fan installed inside the heat dissipation frame, and a filter screen installed inside the heat dissipation frame on one side of the fan.

[0006] The high-voltage capacitor body is provided with a second positioning frame and a first positioning frame from top to bottom on its exterior. A base is installed on the lower surface of the first positioning frame, and guide rods are symmetrically arranged on the upper surface of the second positioning frame. The upper end of the guide rod passes through the top plate, and a screw is provided on the upper surface of the second positioning frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution for an outdoor high-voltage capacitor that is highly stable and easy to install: it includes a high-voltage capacitor body 4 and a box plate 5 that is slidably installed on one side of the high-voltage capacitor body 4. A sealing plate 51 is fixed on one side of the box plate 5, and a heat dissipation frame 52 is installed on the outside of the sealing plate 51. A fan 522 is installed inside the heat dissipation frame 52, and a filter screen 521 is installed on one side of the fan 522 inside the heat dissipation frame 52. This arrangement utilizes the sliding of the box plate 5 on one side of the high-voltage capacitor body 4, which facilitates the disassembly of the box plate 5 and the high-voltage capacitor body 4 for maintenance purposes. The fan 522 can also be used to exchange heat inside the high-voltage capacitor body 4, thereby improving the service life of the high-voltage capacitor body 4.

[0023] The high-voltage capacitor body 4 is provided with a second positioning frame 3 and a first positioning frame 2 from top to bottom on the outside. A base 1 is installed on the lower surface of the first positioning frame 2. Guide rods 32 are symmetrically arranged on the upper surface of the second positioning frame 3. The upper end of the guide rods 32 passes through the top plate 12. A screw 31 is provided on the upper surface of the second positioning frame 3. The rotation of the screw 31 will cause the second positioning frame 3 to move downward and lock the second positioning frame 3 on the outside of the high-voltage capacitor body 4. Thus, the stability of the connection can be improved by using the first positioning frame 2 and the second positioning frame 3.

[0024] like Figure 2 and Figure 3As shown, the lower end of the guide rod 32 is fixed to the upper surface of the second positioning frame 3, and a lightning rod is provided at the upper end of the guide rod 32. A bearing is installed at the middle position of the upper surface of the second positioning frame 3. The lower end of the screw 31 is embedded in the bearing and rotatedly connected to the bearing. The screw 31 is threadedly connected to the top plate 12. This arrangement uses the screw 31 to connect to the top plate 12, so that the second positioning frame 3 can move downward to position the high voltage capacitor body 4, and guide it through the guide rod 32 to improve its lifting stability.

[0025] like Figure 1 and Figure 2 As shown, the first positioning frame 2 and the second positioning frame 3 are symmetrically provided with positioning pins 21 inside. The upper and lower surfaces of the high voltage capacitor body 4 are provided with positioning holes that are compatible with the positioning pins 21. This arrangement ensures the stability of the high voltage capacitor body 4 by having the positioning pins 21 embedded inside the positioning holes.

[0026] like Figure 1 As shown, support columns 11 are symmetrically arranged at the upper end face of the base 1. The upper end of the support column 11 is fixed to the lower surface of the top plate 12. This arrangement uses the support column 11 to ensure the stability of the connection between the base 1 and the top plate 12, so as to facilitate the positioning of the high voltage capacitor body 4 in the future.

[0027] like Figure 4 and Figure 5 As shown, guide rails are provided on both the upper and lower surfaces of the enclosure plate 5. A guide groove that slides against the guide rails is provided on the inner side of the high voltage capacitor body 4. The sealing plate 51 is installed on one side of the high voltage capacitor body 4 by bolts. This arrangement uses the guide rails to guide the movement inside the guide groove, so that the enclosure plate 5 can be guided to move inside the high voltage capacitor body 4, thereby facilitating the opening of the high voltage capacitor body 4 for maintenance.

[0028] The working principle of this utility model is as follows: When using this outdoor high-voltage capacitor, which is highly stable and easy to install, the high-voltage capacitor body 4 is first placed into the first positioning frame 2. During placement, the positioning hole on the lower surface of the high-voltage capacitor body 4 is aligned with the positioning pin 21 in the first positioning frame 2 to achieve positioning of the high-voltage capacitor body 4. After positioning, the screw 31 penetrating the upper surface of the top plate 12 can be rotated. During rotation, since the screw 31 is threadedly connected to the top plate 12, the second positioning frame 3 is guided downward through the guide rod 32. Thus, the second positioning frame 3 can be used to position the high-voltage capacitor. The main body 4 serves a positioning purpose, and the positioning pin 21 inside the second positioning frame 3 is embedded in the positioning hole opened on the upper surface of the high voltage capacitor main body 4 to ensure the stability of the high voltage capacitor main body 4. The structure is simple and practical. The high voltage capacitor main body 4 is an existing product, and its principle and structure will not be discussed in detail here. When it is necessary to maintain the inside of the high voltage capacitor main body 4, it is only necessary to remove the bolts on the outside of the sealing plate 51 and slide the sealing plate 51 forward, that is, slide the box plate 5 on the inside of the high voltage capacitor main body 4 to open it, so as to facilitate the maintenance of its interior. It is practical.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
