Description

Technical Field

[0001] This utility model relates to the field of reactive power compensation technology, specifically to a modular SVG hybrid dynamic reactive power compensation device. Background Technology

[0002] SVG (Static Var Generator) systems are designed with different cabinet or frame structures depending on the voltage level or the number of cascaded units. SVG installation is commonly done in cabinet or wall-mounted configurations to meet various site requirements. The external casing or frame of a complete SVG system serves a fixing function but has no specific functional purpose. This approach leads to the following problems: different voltage levels, cascaded numbers, and capacity ranges of power devices all require different installation cabinets or frames, resulting in a wide variety of cabinet or frame types that are unsuitable for mass production; some cabinets or mounting frames exceed height limits during transport, increasing transportation costs and the overall cost of the complete equipment. Utility Model Content

[0003] The purpose of this invention is to provide a modular SVG hybrid dynamic reactive power compensation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular SVG hybrid dynamic reactive power compensation device, including a screw hole tube, wherein several screw hole tubes are provided, and several hanging plates are connected to the surface of two screw hole tubes. The screw hole tube has several screw holes for easy combination.

[0005] A reactive power generator has a snap-fit ​​connector on its back that can be detached and installed. The snap-fit ​​connector is connected to a mounting plate, which facilitates wall mounting of the reactive power generator and also facilitates installation of the reactive power generator in a reactive power cabinet.

[0006] The base is connected to the surface of the screw hole tube and supports the bottom surface of the reactive power generator, thereby improving the stability of the wall-mounted reactive power generator.

[0007] The connector is connected to the end of the screw hole tube. Several connectors can realize the horizontal combination or stacking combination of the screw hole tubes, which can enable the reactive power generator to be wall-mounted or stacked in batches.

[0008] Furthermore, several reinforcing rods are installed on the surface of the screw hole tube, and the reinforcing rods are located between two adjacent screw hole tubes. The base is connected to an auxiliary rod, and the auxiliary rod is fixedly connected to the reinforcing rod to improve the structural strength. The screw hole tube will not deform or loosen, and the support for the reactive power generator is stable.

[0009] Furthermore, the base surface is provided with two limiting plates, which are snapped into the bottom of the reactive power generator. The hanging plate surface is provided with anti-detachment posts, and the snap-fit ​​seat is fitted onto the surface of the anti-detachment posts. The snap-fit ​​seat surface is equipped with a first handle screw that is screwed to the reactive power generator. Unscrewing the first handle screw allows for quick disassembly of the reactive power generator, facilitating its installation and removal in the reactive power cabinet. The limiting plate surface is screwed with a second handle screw, which is connected to a top plate to hold the reactive power generator in place, ensuring that the reactive power generator does not shift and is arranged more neatly.

[0010] Furthermore, the connector has inserts at both ends, which are inserted into the screw hole tube. Each insert has a threaded hole on all four sides. Changing the insertion position of the connector and the threaded hole facilitates the laying and stacking of reactive power generators.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) Several flat screw hole tubes are fixed with connectors. The assembled screw hole tubes can be used to install the reactive power generator more neatly. The reactive power generator is hung on the mounting plate by the snap-fit ​​seat, which is more convenient to install. Tightening the second handle screw to hold the reactive power generator can prevent the reactive power generator from loosening.

[0013] (2) The vertically arranged screw hole tubes are fixed with connectors, which can stack several reactive power generators and make them easy to put into the reactive power cabinet. They are flexible and convenient to use. According to the voltage level, cascade quantity and capacity range requirements, they can be spliced ​​to form SVG power devices that meet the requirements.

[0014] (3) Components such as screw hole tubes, reinforcing rods, connectors, and hanging plates can be disassembled to save space and avoid damage to components during transportation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-6 This utility model provides a technical solution: a modular SVG hybrid dynamic reactive power compensation device, including a screw hole tube 1, wherein several screw hole tubes 1 are provided, and when wall-mounted, several screw hole tubes 1 are laid out flat to realize the flat installation of the reactive power generator 9, and several hanging plates 8 are connected to the surface of two screw hole tubes 1.

[0025] The reactive power generator 9 has a snap-fit ​​connector 11 detachably installed on its back. The snap-fit ​​connector 11 is connected to the mounting plate 8. When installing the reactive power generator 9, the snap-fit ​​connector 11 is hung on the mounting plate 8, providing a quick installation method and simplifying the installation steps.

[0026] The base 4 is connected to the surface of the screw hole tube 1 and is supported on the bottom surface of the reactive power generator 9. The wall-mounted reactive power generator 9 has stronger stability and is less likely to fall off.

[0027] Connector 3 is connected to the end of the screw hole tube 1. Several connectors 3 can be combined horizontally or stacked to link the screw hole tubes 1 together, making the structure more stable and providing stability support for the installation of the reactive power generator 9.

[0028] In this embodiment, as Figure 1 As shown, a number of reinforcing rods 2 are installed on the surface of the screw hole tube 1. The reinforcing rods 2 are located between two adjacent screw hole tubes 1, which can position the adjacent screw hole tubes 1, improve the installation accuracy of the screw hole tubes 1, and make the assembly speed faster.

[0029] In this embodiment, as Figure 1As shown, the base 4 is connected to an auxiliary rod 7, which is fixedly connected to the reinforcing rod 2 to improve the assembly strength of the base 4. When the reactive power generator 9 is placed on the base 4, the support stability is better.

[0030] In this embodiment, as Figure 1 As shown, the base 4 has two limiting plates 5 on its surface. The limiting plates 5 are stuck at the bottom of the reactive power generator 9. The limiting plates 5 block the reactive power generator 9, which can prevent the reactive power generator 9 from sliding on the surface of the base 4, thus improving safety.

[0031] In this embodiment, as Figure 5 As shown, the surface of the hanging plate 8 is provided with anti-detachment posts 12, and the locking seat 11 is sleeved on the surface of the anti-detachment posts 12. The hanging plate 8 has a certain degree of toughness. The anti-detachment posts 12 open the hanging plate 8 and allow the anti-detachment posts 12 to pass through the hanging plate 8. The reactive power generator 9 can be directly hung on. The surface of the locking seat 11 is provided with a first handle screw 13 that is screwed to the reactive power generator 9. Loosening the first handle screw 13 separates the locking seat 11 from the reactive power generator 9, and the reactive power generator 9 can be removed. The surface of the limiting plate 5 is screwed with a second handle screw 6, and the second handle screw 6 is connected to a top plate 10. Tightening the second handle screw 6 makes the top plate 10 press against the reactive power generator 9 to prevent the reactive power generator 9 from loosening.

[0032] In this embodiment, as Figure 6 As shown, the connector 3 has inserts 14 at both ends. The inserts 14 are inserted into the screw hole tube 1. The four sides of the inserts 14 have threaded holes, which makes it convenient to use bolts to combine the connector 3 and the screw hole tube 1.

[0033] Specifically, in use, bolts are used to assemble the screw hole tube 1, reinforcing rod 2, connecting piece 3, base 4, auxiliary rod 7, and hanging plate 8 into a single unit. Figure 2 As shown, the screw-hole tube 1 is fixed to the wall. The reactive power generator 9 is placed on the base 4. The snap-fit ​​seat 11 is connected to the anti-detachment column 12, and the snap-fit ​​seat 11 is connected to the reactive power generator 9 using the first handle screw 13. Then, the second handle screw 6 is tightened so that the top plate 10 presses against the reactive power generator 9, completing the wall-mounted installation of the reactive power generator 9. Multiple screw-hole tubes 1 can be assembled using the connector 3. Figure 1 As shown, multiple reactive power generators 9 can be wall-mounted for easy installation;

[0034] When installing the reactive power generator 9 into the reactive power cabinet, the upper and lower screw hole tubes 1 are assembled using connectors 3. Figure 4 As shown, several reactive power generators 9 can be stacked in the reactive power cabinet, with gaps between adjacent reactive power generators 9 to facilitate ventilation and heat dissipation. They can be installed according to requirements, making them flexible and convenient to use and meeting different installation needs.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
