Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, in particular to a low-voltage reactive compensation cabinet with a compensator that can be easily replaced. Background Art

[0002] As an essential component of low-voltage power distribution systems, low-voltage reactive power compensation cabinets primarily perform the core function of reactive power compensation, ensuring efficient and stable operation of the power system. Currently, low-voltage reactive power compensation cabinets typically consist of a cabinet, controller, reactive power compensator, and other components.

[0003] After searching, the patent with announcement number CN114336333A discloses a low-voltage reactive compensation cabinet with an easily replaceable compensator. When the compensator fails, the vertical block and the mounting plate are moved to the edge of the box by the moving block, so that the compensator can be easily replaced.

[0004] The above solution allows the compensator to be pulled out of the cabinet, making it easy to replace. However, since the compensator needs to be pulled a certain distance, if the plug on the compensator is not unplugged beforehand, the pulling force between the cable and the connector can easily cause the plug and connector to deform, increasing equipment maintenance costs. To address this issue, we have proposed a low-voltage reactive power compensation cabinet with easily replaceable compensators to effectively address these drawbacks. Summary of the Invention

[0005] The object of the present invention is to provide a low-voltage reactive compensation cabinet with an easily replaceable compensator, so as to solve the problem in the prior art proposed in the above background technology that the plug and the interface are easily damaged during the removal of the compensator.

[0006] The present invention is achieved through the following technical solutions: a low-voltage reactive power compensation cabinet with easily replaceable compensators, comprising a cabinet body and a plurality of compensator bodies, wherein a partition plate arranged horizontally is fixed in the cabinet body, a mounting plate is movably provided on the top of the partition plate, and the mounting plate can be moved forward and backward, and each compensator body is fixed to the top of the mounting plate at intervals along the horizontal direction;

[0007] Two movable plates are symmetrically arranged on the left and right sides of each compensator body. The two symmetrical movable plates can move away from or close to each other. A plug adapted to the corresponding compensator body is fixed on each movable plate.

[0008] Optionally, the left and right sides of the mounting plate are slidably connected with first guide rails, and each first guide rail is fixed to the top of the partition plate, so that the mounting plate can only move forward and backward.

[0009] Optionally, a plurality of linkage plates are fixed to the bottom of the mounting plate at intervals in the horizontal direction, and a clearance opening is formed on the partition plate for each linkage plate to pass through, and each clearance opening extends toward the front of the partition plate;

[0010] A push-pull plate is movably provided at the bottom of the partition. The push-pull plate is penetrated by limiting openings for each linkage plate to pass through, and each limiting opening extends toward the rear of the push-pull plate.

[0011] Optionally, the left and right sides of the push-pull plate are slidably connected with second guide rails, and each second guide rail is fixed to the bottom of the partition plate, so that the push-pull plate can only move forward and backward.

[0012] Optionally, the linkage plate is made of magnetic material, and permanent magnets are fixed at both the front and rear ends of each clearance opening.

[0013] Optionally, the partition is penetrated by a strip opening for each movable plate to pass through one by one, each strip opening is arranged in a horizontal direction, and a guide rod is fixed in each strip opening and can move through the movable plate in a horizontal direction.

[0014] Optionally, a sliding rod is fixed to the bottom of the movable plate, and a sliding groove for each sliding rod to slide one by one is opened on the push-pull plate.

[0015] Optionally, the chute includes an oblique chute and a longitudinal chute sequentially distributed from front to back;

[0016] When the slide bar is located at the front end of the inclined slot, the plug is inserted into the interface of the compensator body; when the slide bar is located in the longitudinal slot, the plug is located outside the interface of the compensator body.

[0017] Optionally, the mounting plate is penetrated by an L-shaped opening for each movable plate to pass through, and each L-shaped opening penetrates the rear side of the mounting plate.

[0018] Optionally, the L-shaped opening includes a horizontal opening and a vertical opening, and the vertical opening passes through the rear side of the mounting plate; when the sliding rod is located in the inclined groove, the movable plate is located in the horizontal opening.

[0019] Compared with the prior art, the present invention provides a low-voltage reactive compensation cabinet with easily replaceable compensators, which has the following beneficial effects:

[0020] 1. The present invention provides a mounting plate and a movable plate. When the compensator body needs to be replaced, the mounting plate is pulled outward, and the movable plates on the left and right sides of the compensator body are moved away from each other. This can drive the plug and the interface on the compensator body to separate, making the plug and the interface less susceptible to deformation and damage due to pulling force, thereby significantly improving the convenience and reliability of equipment maintenance.

[0021] 2. The present invention can realize the rapid replacement of the compensator body by setting a linkage plate, a clearance port, a push-pull plate, a limit port, a slide rod and a slide groove. In the initial state, the linkage plate is embedded between the rear end of the clearance port and the front end of the limit port, thereby locking the mounting plate in the middle of the partition. When force is applied to pull the push-pull plate outward, the mounting plate remains stationary before the linkage plate touches the rear end of the limit port. At this time, the slide rod slides linearly along the slide groove, driving the movable plates on both sides of the compensator body away from each other, so that the plug is separated from the interface on the compensator body. As the push-pull plate continues to move outward, the linkage plate fits tightly with the rear end of the limit port, thereby driving the mounting plate to move outward as a whole, moving the compensator body out to facilitate the replacement operation.

[0022] That is, as the push-pull plate is pulled outward, the mounting plate remains stationary, allowing the plug to separate from the original compensator body. The mounting plate then moves outward synchronously with the push-pull plate, allowing the compensator body to move to the front of the cabinet for easy replacement. After the replacement is complete, the mounting plate first moves inward with the push-pull plate as the new compensator body is pushed inward. The mounting plate then remains stationary, allowing the plug to be inserted into the interface of the new compensator body, significantly improving the efficiency of compensator replacement.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 7 A low-voltage reactive compensation cabinet in which compensators can be easily replaced comprises a cabinet body 1 and several compensator bodies 2. A cabinet door is installed on the front side of the cabinet body 1. After opening the cabinet door, the components inside the cabinet body 1 can be inspected or replaced. A partition 3 arranged in the horizontal direction is fixed in the cabinet body 1 for installing other components in the equipment. A mounting plate 4 is movably arranged on the top of the partition 3. The mounting plate 4 can move forward and backward. Each compensator body 2 is fixed on the top of the mounting plate 4 at intervals in the horizontal direction. After opening the cabinet door, the mounting plate 4 is moved forward to move the compensator body 2 to the front side of the cabinet body 1. The space is larger than the internal space of the cabinet body 1, thereby facilitating the disassembly and assembly of the compensator body 2. In this embodiment, the left and right sides of the mounting plate 4 are slidably connected with a first guide rail 7. The first guide rail 7 is fixed to the top of the partition 3 to enable the mounting plate 4 to move only forward and backward, but not up and down or left and right, thereby ensuring the stability of the mounting plate 4 when it moves forward and backward.

[0033] Two movable plates 5 are symmetrically arranged on the left and right sides of each compensator body 2. These two symmetrical movable plates 5 can move away from or toward each other. A plug 6 compatible with the corresponding compensator body 2 is fixed to each movable plate 5. When the two movable plates 5 move toward each other, the plug 6 can be inserted into the interface of the compensator body 2; when the two movable plates 5 move away from each other, the plug 6 can be removed from the interface. In this embodiment, it should be noted that the plug 6 is connected to other electrical components in the cabinet 1 via cables.

[0034] With this structure, when the compensator body 2 needs to be replaced, the two symmetrical movable plates 5 are first moved away from each other to remove the plug 6, preventing damage to the plug 6 and the interface when the compensator body 2 is subsequently moved outward. The compensator body 2 is then pushed toward the front of the cabinet 1, exposing it to the open operating space. This greatly improves the convenience and safety of disassembly and installation operations, and significantly reduces the technical difficulty and potential losses of equipment maintenance.

[0035] The following describes how the mounting plate 4 moves forward and backward:

[0036] Several linkage plates 8 are fixed horizontally at intervals along the bottom of the mounting plate 4. Clearance openings 9 are formed through the partition 3, allowing each linkage plate 8 to pass through. Each clearance opening 9 extends toward the front of the partition 3. The linkage plates 8 can move forward along the clearance openings 9, thereby driving the mounting plate 4 toward the cabinet door. A sliding plate 10 is movably mounted at the bottom of the partition 3. A handle is fixed to the front of the sliding plate 10 to facilitate the application of external force to the sliding plate 10. Limiting openings 11 are formed through the sliding plate 10, allowing each linkage plate 8 to pass through. Each limiting opening 11 extends toward the rear of the sliding plate 10. In this embodiment, second guide rails 12 are slidably connected to the left and right sides of the sliding plate 10. Each second guide rail 12 is fixed to the bottom of the partition 3. This ensures that the sliding plate 10 can only move forward and backward, not up and down or left and right, improving its stability during movement. It is worth noting that the linkage plates 8 are made of magnetic material, and permanent magnets 13 are fixed to the front and back ends of each clearance opening 9. When the linkage plate 8 is located at the end of the clearance opening 9, the linkage plate 8 can be fixed by magnetic attraction, thereby fixing the position of the mounting plate 4, making it easier to disassemble and assemble the compensator body 2 on top of the mounting plate 4.

[0037] With this structure, in the initial state, the linkage plate 8 contacts the rear end of the clearance opening 9 and the front end of the stop opening 11, thereby stably locking the mounting plate 4 to the middle portion of the partition 3. In the initial stage of outward movement of the push-pull plate 10, the linkage plate 8 does not yet contact the rear end of the stop opening 11, so the mounting plate 4 remains stationary. After the push-pull plate 10 moves outward a certain distance, the linkage plate 8 contacts the rear end of the stop opening 11, driving the mounting plate 4 to move synchronously.

[0038] That is, when the push-pull plate 10 is pulled outward, the mounting plate 4 first remains stationary to facilitate the separation of the plug 6 from the original compensator body 2, and then moves outward to move the original compensator body 2 to the front side of the cabinet 1. Conversely, when the push-pull plate 10 is pushed inward, the mounting plate 4 first moves inward to move the new compensator body 2 into place, and then remains stationary to facilitate the insertion of the plug 6 into the new compensator body 2.

[0039] In this embodiment, it should be noted that the partition 3 is provided with a strip-shaped opening 17 through which each movable plate 5 passes. Each strip-shaped opening 17 is arranged horizontally, and a guide rod 18 is fixed in each strip-shaped opening 17 and is movable horizontally through the movable plate 5. The cooperation between the strip-shaped opening 17 and the guide rod 18 allows the movable plate 5 to move only horizontally along the partition 3 and cannot be separated from the partition 3.

[0040] The following describes how the two bilaterally symmetrical movable plates 5 move away from or approach each other:

[0041] A slide bar 14 is fixed to the bottom of the movable plate 5, and a slide groove 15 is provided on the push-pull plate 10 for each slide bar 14 to slide one by one. When the push-pull plate 10 moves, since the slide bar 14 always slides in the slide groove 15, when the sliding path changes, the two movable plates 5 can be moved away from or closer to each other.

[0042] Specifically, the slide groove 15 includes an oblique groove 151 and a longitudinal groove 152 distributed in sequence from front to back; when the slide rod 14 is located at the front end of the oblique groove 151, the plug 6 is inserted into the interface of the compensator body 2; when the slide rod 14 is located in the longitudinal groove 152, the plug 6 is located outside the interface of the compensator body 2.

[0043] With this structure, initially, the slide bar 14 is located at the front end of the inclined slot 151, and the plug 6 is inserted into the interface of the compensator body 2. When the push-pull plate 10 is pulled outward, the compensator body 2 remains stationary. At this time, the slide bar 14 slides along the inclined slot 151 toward the longitudinal slot 152, thereby moving the two movable plates 5 away from each other to remove the plug 6. The push-pull plate 10 then continues to move outward, moving the compensator body 2 outward for replacement. During this process, the slide bar 14 remains in the longitudinal slot 152.

[0044] After the replacement is complete, the push-pull plate 10 is pushed inward, causing the new compensator body 2 to move inward and remain stationary once in place. The push-pull plate 10 then continues to move inward, driving the slide bar 14 along the longitudinal slot 152 into the oblique slot 151, thereby driving the two movable plates 5 toward each other, allowing the plug 6 to be inserted into the new compensator body 2, thereby completing the rapid replacement of the compensator body 2. This linkage design based on the trajectory change of the slide slot 15 achieves orderly coordination between the insertion and removal of the plug 6 and the movement of the compensator through mechanical structure, greatly improving the safety and efficiency of equipment replacement.

[0045] In this embodiment, the mounting plate 4 is penetrated by L-shaped openings 16 for each movable plate 5 to pass through. Each L-shaped opening 16 penetrates the rear side of the mounting plate 4 so that the presence of the movable plate 5 does not affect the outward movement of the mounting plate 4.

[0046] Specifically, L-shaped opening 16 includes a transverse opening 161 and a longitudinal opening 162. The longitudinal opening 162 penetrates the rear side of the mounting plate 4, forming an open passageway that provides ample space for the movement of the movable plate 5. When the slide bar 14 is located in the inclined slot 151, the movable plate 5 is located in the transverse opening 161. When the slide bar 14 is located in the longitudinal slot 152, the movable plate 5 is located in or outside the longitudinal opening 162.

[0047] With the above design, the L-shaped opening 16 forms a precise match with the motion trajectory of the slide 15: when the slide bar 14 is located in the oblique groove 151, the movable plate 5 is embedded in the horizontal opening 161, and at this time the plug 6 and the compensator body 2 maintain a stable connection; as the slide bar 14 slides along the oblique groove 151 to the longitudinal groove 152, the movable plate 5 is synchronously translated from the horizontal opening 161 to the longitudinal opening 162, and can eventually extend to the outside of the longitudinal opening 162, realizing the complete separation of the plug 6 from the interface. This structural design, through the spatial guidance of the L-shaped opening 16, not only guarantees the freedom of the movable plate 5 during the plug 6 insertion and removal process, but also ensures that it will not cause mechanical obstruction when the mounting plate 4 is translated, providing a smooth motion path for the compensator replacement operation. During the equipment maintenance process, this structure makes the coordinated movement of the movable plate 5 and the mounting plate 4 more efficient, effectively improving the convenience and reliability of the compensator disassembly and assembly.
