Description

Technical Field

[0001] This utility model belongs to the technical field of combined installation structure, specifically a combined installation structure for a reactive power compensation device. Background Technology

[0002] Reactive power compensation devices improve power quality in a wide range of ways, mainly including reactive power compensation, harmonic suppression, reduction of voltage fluctuations and flicker, and resolution of three-phase imbalance. Devices used for reactive power compensation and harmonic mitigation include passive power filters, which combine reactive power compensation and voltage regulation functions and are generally custom-designed based on the parameters of the harmonic source, the electrical characteristics of the installation point, and user requirements. Static var compensators (SVCs) are important devices for comprehensively managing voltage fluctuations, flicker, harmonics, and voltage imbalance. Active power filters are a new type of power electronic device that dynamically suppresses harmonics and compensates for reactive power. They can compensate for harmonics and reactive currents with varying frequencies and amplitudes and are mainly used in low-voltage power distribution systems.

[0003] In the prior art, Chinese patent CN221530680U discloses an installation structure for a high-voltage reactive power compensation device, including a square tube fixing frame, a mounting plate, and a cabinet door. Movable structures are provided on both sides inside the square tube fixing frame, and a mounting plate is provided at the top of the movable structures. The movable structures include rollers, a moving groove, a limiting seat, a locking pin, a spring, a pull rod, and a fixing seat. The moving groove is fixed to both sides inside the cabinet door, and rollers are provided inside the moving groove. This utility model provides an installation structure for a high-voltage reactive power compensation device. By pulling the pull rod, the locking pin is disengaged from the limiting seat, and then the mounting plate is pulled laterally, causing the rollers to move the mounting plate away from the device's interior. Removing the mounting plate facilitates the installation and fixing of electrical components.

[0004] However, the installation structure of the high-voltage reactive power compensation device provided in the above technical solution still has many shortcomings in actual application. For example, when installing the reactive power compensation device, the fixed structure and position of the installation components make it unsuitable for reactive power compensation devices of different sizes, resulting in poor applicability.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that the existing reactive power compensation device installation structure is not suitable for reactive power compensation devices of different sizes due to the fixed structure and position of the installation components, resulting in poor applicability, the present invention adopts the following technical solution.

[0007] A combined installation structure for a reactive power compensation device includes a mounting plate. Movable platforms are provided at both ends of the front of the mounting plate, and the back of the movable platforms is flush with the front of the mounting plate.

First sliding posts are engaged at both ends of the movable platforms, and the first sliding posts are slidably connected to the first sliding grooves. A second sliding groove is provided on the front of the movable platforms, and second sliding posts are slidably connected to both ends of the second sliding grooves. A connecting plate is sleeved on the outer side of each second sliding post.

[0008] Preferably, the outer side of the second sliding column is fitted with the inner side of the central circular hole of the connecting plate, and mounting holes are provided at both ends of the connecting plate, the mounting holes being symmetrical about the horizontal center line of the connecting plate.

[0009] Preferably, the end of the first slide column is threaded with a first locking ring, and the end of the second slide column is threaded with a second locking ring. The first slide column is symmetrical about the horizontal center line of the movable table, and both the first locking ring and the second locking ring have a quincunx structure.

[0010] Preferably, the mounting plate has multiple ventilation holes at its center, which are arranged in a rectangular array on the mounting plate and extend through both sides of the mounting plate.

[0011] Preferably, the back of the mounting plate is provided with multiple pads, which are symmetrical about the vertical center line of the mounting plate, and the pads and the mounting plate form an integrated structure.

[0012] Preferably, the mounting plate has positioning holes at all four corners, which are symmetrical about the vertical center line of the mounting plate. The mounting plate also has mounting slots on both sides, which penetrate the mounting plate and are symmetrical about the horizontal center line of the mounting plate.

[0014] Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the positioning holes on the connecting plate, along with bolts, to connect the reactive power compensation device to the device. The first sliding groove and the first sliding column work together to allow the movable platform to slide longitudinally. The first locking ring increases the friction between the back of the movable platform and the front of the mounting plate, thus fixing the first sliding column at a specific position in the first sliding groove. The second sliding groove and the second sliding column work together to allow the connecting plate to move laterally. Tightening the second locking ring restricts the sliding of the second sliding column, facilitating the fixing of the connecting plate's position. Therefore, this device can be used with reactive power compensation devices of different sizes. Attached Figure Description

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] Please see Figure 1-5 This utility model provides an embodiment of a combined installation structure for a reactive power compensation device, comprising a mounting plate 1. Positioning holes 13 are provided at each of the four corners of the mounting plate 1, symmetrical about the vertical center line of the mounting plate 1. Mounting slots 14 are provided on both sides of the mounting plate 1, penetrating the mounting plate 1, and symmetrical about the horizontal center line of the mounting plate 1. Through the positioning holes 13 on the mounting plate 1, and with the use of external bolts, the mounting plate 1 can be fixed to an external electrical box, completing the installation of the device. Using the mounting slots 14, multiple devices can be spliced ​​together via a U-shaped frame, facilitating combined installation and improving the applicability of the device.

[0028] In this embodiment, movable platforms 2 are provided at both ends of the front side of the mounting plate 1. The back of the movable platforms 2 is in contact with the front side of the mounting plate 1. First sliding grooves 3 are provided on both sides of the mounting plate 1 for the movable platforms 2 to slide. First sliding posts 4 are engaged at both ends of the movable platforms 2. The first sliding posts 4 and the first sliding grooves 3 are slidably connected. A second sliding groove 5 is provided on the front side of the movable platforms 2. Second sliding posts 6 are slidably connected at both ends of the second sliding groove 5. A connecting plate 7 is sleeved on the outer side of the second sliding posts 6. The outer side of the second sliding posts 6 is in contact with the inner side of the central circular hole of the connecting plate 7. Mounting holes 8 are provided at both ends of the connecting plate 7. The mounting holes 8 are symmetrical about the horizontal center line of the connecting plate 7. The back of the reactive power compensation device is in contact with the front side of the mounting plate 1. By using the mounting holes 8 on the connecting plate 7 and the use of bolts, the reactive power compensation device can be connected to this device. Through the cooperation of the first sliding grooves 3 and the first sliding posts 4, the movable platforms 2 can slide longitudinally.

[0029] In this embodiment, the end of the first sliding column 4 is threaded with a first locking ring 9, and the end of the second sliding column 6 is threaded with a second locking ring 10. The first sliding column 4 is symmetrical about the horizontal center line of the movable platform 2. The first locking ring 9 and the second locking ring 10 both have a quincunx structure. The first locking ring 9 increases the friction between the back of the movable platform 2 and the front of the mounting plate 1, thereby fixing the first sliding column 4 at a certain position in the first sliding groove 3. Through the cooperation of the second sliding groove 5 and the second sliding column 6, the connecting plate 7 can move laterally. Tightening the second locking ring 10 restricts the sliding of the second sliding column 6, making it easier to fix the position of the connecting plate 7. This allows the device to be used with reactive power compensation devices of different sizes.

[0030] In this embodiment, the mounting plate 1 has a plurality of ventilation holes 11 at its center. The ventilation holes 11 are arranged in a rectangular array on the mounting plate 1 and penetrate both sides of the mounting plate 1. The back of the mounting plate 1 is provided with a plurality of pads 12. The pads 12 are symmetrical about the vertical center line of the mounting plate 1 and form an integrated structure with the mounting plate 1. The pads 12 can separate the mounting plate 1 from the electrical box surface. With the use of the ventilation holes 11, it is convenient to ventilate and dissipate heat for the reactive power compensation device, thereby improving the practicality of the device.

[0031] In this embodiment, the first slide groove 3 is symmetrical about the vertical center line of the mounting plate 1, the diameter of the first slide column 4 matches the width of the first slide groove 3, and a grounding wire 15 is fixedly connected to the bottom of the mounting plate 1. The grounding wire 15 enables the device to have an anti-static function and improves the protection of the device against reactive power compensation devices.

[0032] Working principle: When using this device, firstly, by using the positioning holes 13 on the mounting plate 1 and external bolts, the mounting plate 1 can be fixed to the external electrical box to complete the installation of this device. Using the mounting slot 14, multiple devices can be spliced ​​together by the U-shaped frame, which facilitates the combined installation of this device and improves its applicability.

[0033] The back of the reactive power compensation device is placed against the front of the mounting plate 1. Using the mounting holes 8 on the connecting plate 7 and bolts, the reactive power compensation device can be connected to this device. The first sliding groove 3 and the first sliding column 4 work together to allow the movable platform 2 to slide longitudinally. The first locking ring 9 increases the friction between the back of the movable platform 2 and the front of the mounting plate 1, thus fixing the first sliding column 4 at a certain position in the first sliding groove 3. The second sliding groove 5 and the second sliding column 6 work together to allow the connecting plate 7 to move laterally. Tightening the second locking ring 10 restricts the sliding of the second sliding column 6, facilitating the fixing of the connecting plate 7. This allows the device to be used with reactive power compensation devices of different sizes. The grounding wire 15 provides anti-static functionality, enhancing the device's protection against reactive power compensation devices. The pads 12 separate the mounting plate 1 from the electrical box surface. Combined with the ventilation holes 11, this facilitates ventilation and heat dissipation for the reactive power compensation device, thereby improving the device's practicality.

[0034] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention.
