Description

TECHNICAL FIELD

[0001] The utility model relates to wall -hanging compensation cabinet technical field especially relates to a wall -hanging reactive compensation cabinet. BACKGROUND

[0002] The reactive compensation cabinet is the key electrical equipment of the power system and is used for improving the power quality. The working principle is based on the concept of reactive power and is adjusted by capacitors, reactors and other devices. The capacitor bank is composed of multiple units and can be switched in groups. The reactor should cope with the excess of capacitive reactive power. The controller monitors the grid parameters and controls the switching according to the algorithm. It has a significant function and can improve the power factor. For example, industrial enterprises can reduce the reactive current and fines and improve the power transmission capacity. It can reduce line loss because the current is reduced by reducing reactive power. It can also stabilize the grid voltage and ensure the normal operation of electrical equipment under varying loads. In addition, the compensation cabinet is generally fixed on the ground.

[0003] The wall -hanging reactive compensation cabinet in the prior art is composed of multiple mechanisms. The cabinet structure includes a metal shell, a cabinet door with a hinge and a handle, and an internal cavity. The shell serves as a protective function. The support and fixing device has a vertical plate, a connecting bottom block, a supporting assembly and a clamping assembly to ensure the stability of the cabinet wall hanging. The reactive compensation elements include capacitors, reactors, fuses and other core components to achieve reactive power compensation and circuit protection. The heat dissipation assembly dissipates heat with the help of fans, heat sinks and other heat dissipation elements. The control and protection device includes a controller, a relay and other devices to ensure accurate and safe operation. The electrical connection system and other accessories improve the overall function and operational convenience.

[0004] The existing reactive compensation cabinet is usually fixed on the ground, which has many drawbacks. First, it will greatly occupy the ground space, limiting the layout planning of other necessary equipment in the cramped power distribution room or electrical equipment room, resulting in a chaotic overall space layout, which is not conducive to the orderly arrangement and management of equipment. Second, due to the fixed position and proximity to the ground, when the ground is flooded due to unexpected situations such as heavy rain or pipe rupture, the reactive compensation cabinet is easily flooded, and the internal electrical components may be damaged due to short circuit, which seriously affects the normal operation and service life of the equipment. Third, being fixed on the ground is not conducive to flexible adjustment of the position of the reactive compensation cabinet according to the actual load distribution, making it difficult to achieve precise reactive compensation for different regional loads, thereby reducing compensation efficiency, increasing line reactive loss and affecting the energy saving and stable operation of the power system. Therefore, a wall -hanging reactive compensation cabinet is proposed to solve the above problems. SUMMARY

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0034] With reference to Figure 1 And Figure 2 An embodiment provided by the utility model: a wall-mounted reactive compensation cabinet, including fixed plate 2, fixed plate 2 can select the thickness as high-strength aluminum alloy material, it has the advantages of lighter quality, corrosion resistance and good mechanical strength etc., can be stably installed on the wall and bear the weight of cabinet 1. Cabinet 1 is fixedly connected to the side wall of fixed plate 2, and the shell of cabinet 1 is made of cold-rolled steel plate. The surface of the cold-rolled steel plate is treated by anti-corrosion and electrostatic spraying process, so that it has strong corrosion resistance and beautiful appearance, which can effectively protect the internal electrical elements. The side wall of cabinet 1 is fixedly connected with a sleeve ring 3, and the sleeve ring 3 is made of stainless steel. The stainless steel sleeve ring 3 can provide a stable connection structure and is durable and not easy to rust and damage. The inner wall of sleeve ring 3 is provided with a quick release mechanism;

[0035] The quick release mechanism includes a first clamping block 7, which can be made of engineering plastic material and has good wear resistance, self-lubricating property and certain mechanical strength, facilitating sliding operation on the inner wall of sleeve ring 3 and not easy to damage. The outer wall of first clamping block 7 is arranged on the inner wall of sleeve ring 3, and a connecting column 8 is slidably connected in the first clamping block 7. The connecting column 8 is made of carbon steel and is galvanized to enhance its strength and rust resistance. A first rotating disc 6 is rotatably connected to the inner wall of first clamping block 7, which is made of aluminum alloy material and has light weight and flexible rotation. The first rotating disc 6 is rotatably connected to the outer wall of connecting column 8, and a connecting disc 5 is rotatably connected to the side wall of first rotating disc 6. The connecting disc 5 can be made of engineering plastic material, such as polycarbonate. A rotating disc 4 is rotatably connected in the connecting disc 5, and a second rotating disc 9 is fixedly connected to one end of rotating disc 4. The second rotating disc 9 is made of aluminum alloy material, which is the same as the material of first rotating disc 6. The second rotating disc 9 is rotatably connected to the outer wall of connecting column 8.

[0036] Specifically, when using the reactive compensation cabinet, wall-mounted installation operation is needed. First, the operator manually rotates the rotating disc 4. The rotating disc 4 starts to rotate around its axis due to external force. The rotation of the rotating disc 4 will drive the second rotating disc 9 connected thereto to rotate synchronously. In the rotating process of the second rotating disc 9, force is transmitted to the connecting column 8, prompting the connecting column 8 to start rotating. The connecting column 8 and the first rotating disc 6 also have a specific linkage mechanism. When the connecting column 8 rotates, it will drive the first rotating disc 6 to rotate. In the rotating process of the connecting column 8, the special design of its structure enables the first clamping block 7 to be driven and gradually spread outward. With the spread of the first clamping block 7, the anti-skid rubber strip 15 connected thereto will be gradually pressed against the inner wall of the sleeve ring 3. The anti-skid rubber strip 15 has good elasticity and friction. When it is tightly pressed against the inner wall of the sleeve ring 3, it can generate enough friction and resistance, thereby stably fixing the reactive compensation cabinet on the wall surface, successfully achieving the effect of being fixed on the wall. It provides a reliable fixing method for the wall-mounted installation of the reactive compensation cabinet, and guarantees the stability and safety of the equipment in the wall-mounted state.

[0037] With reference to Figure 1 , Figure 3 and Figure 4The cabinet 1 is internally fixedly connected with a track 10, which can be made of aluminum alloy, has the characteristics of light weight, high strength and smooth surface, can provide smooth and stable guiding effect for the sliding of the drawer 12, reduce the friction and resistance when the drawer 12 slides, reduce wear and tear, and prolong the service life of the track 10. The track 10 is fixedly connected with the drawer 12 on the side wall, and the main body of the drawer 12 can be made of fireproof and insulating engineering plastic material, such as flame-retardant ABS plastic. This material not only can effectively protect the internal connected electronic components from external electromagnetic interference, but also has good mechanical processing performance and certain heat resistance, which can meet the use requirements of the drawer 12 under different working conditions. The drawer 12 is fixedly connected with a handle 11 on the side wall, which can be made of stainless steel. The stainless steel handle 11 is firm and durable and has good touch, which is convenient for operators to open and close the drawer 12. The drawer 12 is fixedly connected with a second clamping block 14 on the side wall, which can be made of nylon material and has certain strength and wear resistance, which can maintain good shape and performance in repeated contact with the clamping plate 13. The clamping plate 13 can be made of carbon steel and plated with chromium. The surface of the clamping plate 13 plated with chromium has high hardness, wear resistance and is not easy to rust, which can tightly cooperate with the second clamping block 14 to realize the locking function of the drawer 12. The second clamping block 14 is arranged in the clamping plate 13. The cabinet 1 is slidingly connected with a plurality of drawers 12, and the drawer 12 is used to connect electronic components. The first clamping block 7 is fixedly connected with an anti-skid rubber strip 15 on the outer wall, which can be made of rubber material. The rubber anti-skid rubber strip 15 has good elasticity and friction, and is slidingly arranged in the inner wall of the sleeve ring 3. When the first clamping block 7 expands, it can tightly fit the inner wall of the sleeve ring 3, effectively prevent the cabinet 1 from sliding off from the wall-mounted installation position, and ensure the stability and safety of the equipment installation;

[0038] Specifically, when the drawer 12 needs to be operated, first hold and then pull the handle 11 with hands, the handle 11 is subjected to the action of human force, and then the action force is transmitted to the drawer 12 connected with the handle 11, so as to drive the drawer 12 to start sliding along the predetermined track 10. The track 10 not only provides accurate guidance for the sliding of the drawer 12, but also ensures that the drawer 12 can be stably fixed in the interior of the cabinet 1, avoiding deviation or shaking of the drawer 12 during the sliding process. After the drawer 12 slides to the appropriate position, if it is pushed back to the original position, the drawer 12 is pushed at this time, and the force acting on the drawer 12 further drives the second clamping block 14 on one side of the drawer 12 to move synchronously. Since the second clamping block 14 and the third clamping block 16 are structurally related to each other, the force acting on the second clamping block 14 will simultaneously cause the third clamping block 16 on the side wall to move correspondingly. During the movement, the third clamping block 16 gradually approaches and finally tightly clamps the outer wall thereof to the inner wall of the clamping plate 13, forming a preliminary fixed state. Then, the rhombic block 17 is clamped to the outer wall of the third clamping block 16, and through this double clamping mode, the freedom of the third clamping block 16 is effectively limited, thereby achieving the effect of stably locking the drawer 12, and ensuring that the drawer 12 remains fixed in the cabinet 1 and will not slide out of the cabinet 1 due to accidental collision or slight vibration.

[0039] Working principle: when the reactive power compensation cabinet is used, first rotate the rotating disc 4, the rotating disc 4 is driven to rotate the second rotating disc 9, the second rotating disc 9 is driven to rotate the connecting column 8, the connecting column 8 rotates and drives the first rotating disc 6 to rotate, then the connecting column 8 rotates to drive the first clamping block 7 to spread, and the first clamping block 7 spreads to clamp the anti-skid rubber strip 15 to the inner wall of the sleeve ring 3, achieving the effect of being fixed on the wall, then pull the handle 11, the handle 11 is driven to drive the drawer 12 to slide, and the drawer 12 is fixed in the interior of the cabinet 1 through the track 10, then push the drawer 12, the drawer 12 is driven to move the second clamping block 14, and the force acting on the second clamping block 14 drives the third clamping block 16 on the side wall to move, the movement of the third clamping block 16 clamps the outer wall thereof to the inner wall of the clamping plate 13, then the rhombic block 17 is clamped to the outer wall of the third clamping block 16, achieving the effect of locking the drawer 12.

[0040] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
