Description

Technical Field

[0001] This utility model relates to the field of compensation mechanism technology, and in particular to a capacitor compensation mechanism that can be quickly replaced. Background Technology

[0002] A low power factor in a power system reduces equipment utilization, increases power supply investment, impairs voltage quality, reduces equipment lifespan, and significantly increases line losses. Therefore, compensation is necessary, and capacitor banks are a type of reactive power compensation device that is widely used in power distribution systems in industrial and manufacturing plants.

[0003] According to the patent application published on the patent website (authorization announcement number: CN218214999U), "This application relates to the field of capacitor cabinets, specifically a capacitor cabinet with a quick-replaceable capacitor, including a capacitor cabinet body. Side fixing frames are fixedly connected to both sides of the cabinet body. A fixing plate is bolted to the lower end of the side fixing frames, and mounting plates are evenly placed on the top of the fixing plates. A capacitor body is fixedly connected to the top of the mounting plates. A pressure plate is slidably connected between the side fixing frames. This application uses a guide post that engages with a guide hole, making it easy to place the capacitor body in a designated position. Pulling the pull rod and pressing the pressure plate causes the locking rod to engage with the locking hole for locking. Releasing the pull rod provides a limit fixation, ultimately achieving quick installation of the capacitor body. Conversely, simply lifting the pressure plate allows the capacitor body to be removed, eliminating the need to disassemble the mounting bolts and achieving quick replacement of the capacitor body, thus solving the problem of inconvenient quick capacitor replacement."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model requires all capacitors to be fixed together by pressure plates. When a single capacitor needs to be replaced, all capacitors must be released first before the target capacitor can be replaced. This increases the complexity and time of the operation and reduces the convenience of replacing capacitors. Furthermore, the process of releasing the pressure plates may interfere with or affect other normally functioning capacitors. Therefore, it is necessary to improve the capacitor replacement compensation mechanism to solve the above problems. Utility Model Content

[0006] To overcome the problem that when a single capacitor needs to be replaced, all capacitors must be unsecured first before the target capacitor can be replaced individually, which increases the complexity and time of the operation, reduces the convenience of capacitor replacement, and may easily cause interference or impact on other normally functioning capacitors.

[0007] The technical solution of this utility model is as follows: a quick-replacement capacitor compensation mechanism, including a housing, a fixed frame plate, and a dustproof component. The housing has a door panel inside, a dustproof component inside, a fixed frame plate fixedly connected inside, a mounting hole inside the fixed frame plate, a pin inside the mounting hole, a mounting plate fixedly connected to the top of the pin, a capacitor body fixedly connected to the top of the mounting plate, a fixed frame fixedly connected to the top of the fixed frame plate, and a locking block slidably connected inside the fixed frame plate, the locking block engaging inside the mounting plate.

[0008] Preferably, the mounting plate has a matching groove at the corresponding position of the locking block, and the locking block is engaged in the groove of the mounting plate.

[0009] Preferably, the top of the card block is rounded.

[0010] Preferably, a control box is fixedly connected inside the housing, a lever is fixedly connected to the inside of the block, the lever is slidably connected inside the fixed frame, an optical axis is fixedly connected inside the fixed frame, the lever is slidably connected to the outside of the optical axis, and a spring is fixedly connected between the lever and the fixed frame.

[0011] Preferably, the fixed frame has a matching groove at the corresponding position of the lever, and the lever slides within the groove of the fixed frame.

[0012] Preferably, the dustproof component includes a first heat dissipation groove inside the housing, a first dustproof frame on the inner wall of the housing, a first dustproof mesh body fixedly connected inside the first dustproof frame, a first hexagon socket head cap screw inside the first dustproof frame, a second heat dissipation groove inside the door panel, a second dustproof frame at the rear end of the door panel, a second dustproof mesh body fixedly connected inside the second dustproof frame, the second dustproof mesh body located at the rear end of the second heat dissipation groove, and a second hexagon socket head cap screw inside the second dustproof frame, which is threaded into the door panel.

[0013] Preferably, there are two sets of first heat dissipation slots, which are symmetrically distributed on the left and right sides of the box, and there are two sets of first dustproof net bodies, which are both located inside the first heat dissipation slots.

[0014] The beneficial effects of this utility model are as follows: Compared to the previous method where replacing a single capacitor required first releasing all the capacitors from their mounting plates, this new method uses a locking block inside the mounting plate to quickly install the capacitor body. By removing the locking block from the mounting plate, the capacitor body can be easily removed for replacement. This reduces the complexity and time required for capacitor replacement, improves the convenience of individual capacitor replacement, and allows for easy replacement of the target capacitor without interfering with or affecting other normally functioning capacitors. This enhances its practicality and avoids the problems of increased operational complexity and time, and the potential for interference with other normally functioning capacitors.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment of a quick-replacement capacitor compensation mechanism, including a housing 1, a fixing bracket 22, and a dustproof component. The housing 1 has a door panel 4 inside, and the dustproof component is also inside. The fixing bracket 22 is fixedly connected inside the housing 1. The fixing bracket 22 has mounting holes 23 inside, and a pin 26 is installed inside the mounting holes 23. A mounting plate 24 is fixedly connected to the top of the pin 26, and a capacitor body 25 is fixedly connected to the top of the mounting plate 24. The top of the fixing bracket 22 is also fixedly connected to... A fixed frame 27 is attached, and a locking block 28 is slidably connected inside the fixed frame 27. The locking block 28 engages with the inside of the mounting plate 24, enabling quick installation of the capacitor body 25. By moving the locking block 28 away from the mounting plate 24, the capacitor body 25 can be released from its fixation, allowing it to be removed for replacement. This reduces the complexity and time required for replacing the capacitor body 25, improves the convenience of replacement, and facilitates individual replacement of the target capacitor body 25. To improve practicality, the dustproof components enhance heat dissipation efficiency through the first heat dissipation slot 31 and the second heat dissipation slot 35. The first dustproof mesh body 33 and the second dustproof mesh body 37 prevent dust from entering the interior of the housing 1, thus extending the service life of the capacitor body 25. The mounting plate 24 has corresponding slots on the corresponding positions of the locking blocks 28. The locking blocks 28 engage with the slots on the mounting plate 24, allowing for the installation and removal of the capacitor body 25, thus improving the ease of replacing the capacitor body 25. For quick installation, the top of the locking block 28 is arc-shaped. When the mounting plate 24 contacts the arc end of the locking block 28, it causes the locking block 28 to move outward, compressing the spring 211. When the mounting plate 24 contacts the fixing bracket plate 22, the slot of the mounting plate 24 corresponding to the locking block 28 is in the corresponding position of the locking block 28. At this time, the spring 211 drives the lever plate 29 to reset, causing the locking block 28 to spring back and lock the locking block 28 into the slot of the mounting plate 24, thus realizing the quick installation of the capacitor body 25.

[0024] Please see Figure 2 - Figure 4In this embodiment, a control box 21 is fixedly connected inside the housing 1, a lever 29 is fixedly connected to the inner side of the locking block 28, the lever 29 is slidably connected inside the fixed frame 27, an optical axis 210 is fixedly connected inside the fixed frame 27, the lever 29 is slidably connected to the outside of the optical axis 210, and a spring 211 is fixedly connected between the lever 29 and the fixed frame 27. The capacitor body 25 is quickly installed by locking the locking block 28 inside the mounting plate 24. The capacitor body 25 is released by moving the locking block 28 away from the mounting plate 24. The capacitor body 25 can be removed for replacement, enabling quick replacement of the capacitor body 25. This facilitates the individual replacement of the target capacitor body 25, reducing the complexity and time required for replacing the capacitor body 25 and improving the convenience of replacement. It also does not interfere with or affect other normally operating capacitors, thus enhancing its practicality. The fixed frame 27 has a matching groove at the corresponding position of the lever 29. The lever 29 slides within the groove of the fixed frame 27, limiting the locking block 28 and improving the stability of the locking block 28.

[0025] Please see Figure 1 , Figure 5 - Figure 6 In this embodiment, the dustproof component includes a first heat dissipation groove 31, which is formed inside the housing 1. A first dustproof frame 32 is provided on the inner wall of the housing 1. A first dustproof mesh body 33 is fixedly connected inside the first dustproof frame 32. A first hexagon socket head cap screw 34 is provided inside the first dustproof frame 32 and threadedly connected to the inside of the housing 1. A second heat dissipation groove 35 is formed inside the door panel 4. A second dustproof frame 36 is provided at the rear end of the door panel 4. A second dustproof mesh body 37 is fixedly connected inside the second dustproof frame 36 and is located at the rear end of the second heat dissipation groove 35. A second hexagon socket head cap screw 37 is provided inside the second dustproof frame 36. Bolt 38, the second hexagon socket bolt 38 is threaded into the inside of the door panel 4. The dustproof component improves heat dissipation efficiency through the first heat dissipation groove 31 and the second heat dissipation groove 35. Through the first dustproof mesh body 33 and the second dustproof mesh body 37, it prevents dust from entering the inside of the box 1 and improves the service life of the capacitor body 25. Two sets of first heat dissipation grooves 31 are provided, and the two sets of first heat dissipation grooves 31 are symmetrically distributed on the left and right sides of the box 1. Two sets of first dustproof mesh bodies 33 are also provided, and the two sets of first dustproof mesh bodies 33 are both located inside the first heat dissipation grooves 31, which improves the heat dissipation effect inside the box 1, prevents dust from entering the inside of the box 1, and improves the service life of the electronic components inside the box 1.

[0026] During operation, when installing the capacitor body 25, first open the door panel 4, align the pin 26 at the bottom of the capacitor body 25 with the mounting hole 23, and lower it. Because the lower diameter of the pin 26 is small, it easily guides the capacitor body 25 into place. The two pins 26 limit the installation of the capacitor body 25. When the mounting plate 24 contacts the arc end of the locking block 28, it causes the locking block 28 to move outward, compressing the spring 211. When the mounting plate 24 contacts the fixing bracket plate 22, the groove of the mounting plate 24 corresponding to the locking block 28 is in the corresponding position of the locking block 28. At this time, the spring 211 drives the lever 29 to reset, causing the locking block 28 to spring back, thus locking the locking block 28. The capacitor body 25 is quickly installed by snapping into the slot of the mounting plate 24. Conversely, by simply moving the lever 29 outward, the latch 28 is moved away from the mounting plate 24, releasing the capacitor body 25 from its fixation, allowing it to be removed for replacement. This enables quick replacement of the capacitor body 25, facilitating the individual replacement of the target capacitor body 25 without interfering with or affecting other normally functioning capacitors. The first heat dissipation slot 31 and the second heat dissipation slot 35 improve heat dissipation efficiency, while the first dustproof mesh body 33 and the second dustproof mesh body 37 prevent dust from entering the interior of the housing 1, thus extending the service life of the capacitor body 25 and the electronic components inside the housing 1.

[0027] Through the above steps, the capacitor body 25 is quickly installed by locking the latch 28 inside the mounting plate 24. By moving the latch 28 away from the mounting plate 24, the capacitor body 25 can be removed and replaced. This facilitates the individual replacement of the target capacitor body 25, thus solving the problems of increased operation complexity and time, and the potential for interference or impact on other normally functioning capacitors.
