Description

Technical Field

[0001] This utility model relates to the technical field of capacitor banks, and in particular to a novel low-voltage capacitor bank that facilitates heat dissipation. Background Technology

[0002] Most loads in power systems are inductive, and the widespread use of power electronic equipment by power-consuming enterprises results in a low power factor in the power grid. A low power factor reduces equipment utilization, increases power supply investment, impairs voltage quality, shortens equipment lifespan, and significantly increases line losses. To mitigate the energy waste and other adverse factors affecting power supply caused by a low power factor, it is essential to effectively improve the power factor. Clearly, it is unreasonable and usually impossible for generators to provide all reactive power and transmit it over long distances. A more reasonable approach is to generate reactive power where it is needed, i.e., by adding reactive power compensation equipment and devices. Therefore, by connecting capacitor banks (i.e., low-voltage capacitor banks) to the power system, inductive loads can be balanced, the power factor improved, and equipment utilization enhanced.

[0003] However, existing low-voltage capacitor banks use ventilation holes on the side walls of drawer cabinets to dissipate heat, but because the side walls of the drawer cabinets are located inside the overall cabinet body, the heat dissipation effect is not good.

[0004] In view of this, the inventor has designed a new type of low-voltage capacitor bank that is easy to dissipate heat, and this invention is thus derived. Utility Model Content

[0035] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0036] Please see Figures 1 to 9 This invention relates to a novel low-voltage capacitor bank with improved heat dissipation, comprising a cabinet body 10, guide rails 20, and drawer cabinets 30. The cabinet body 10 has several support plates 11 arranged vertically to form receiving positions between adjacent support plates 11. Guide rails 20 are arranged on the cabinet body 10, with two guide rails corresponding to each receiving position. Several drawer cabinets 30 are arranged, corresponding to the receiving positions, and are slidably connected to the guide rails 20 within the receiving positions. Each drawer cabinet 30 has a drawer cover 32 with several ventilation holes 321. A filter screen 40 is installed on each drawer cabinet 30 corresponding to the ventilation holes 321, and the filter screen 40 is movably connected to the drawer cover 32. This invention improves heat dissipation by providing ventilation holes 321 on the drawer cover 32 of the drawer cabinets 30, allowing air to enter from the outside of the cabinet body 10. Simultaneously, the filter screens 40 effectively prevent most dust from entering, thus extending the service life of the low-voltage capacitor bank.

[0037] Please refer to details. Figure 6 , 9 The filter screen 40 has an outer frame 41 and a mesh plate 42 set inside the frame 41. The mesh plate 42 has several small air inlets to ensure ventilation while appropriately preventing dust from entering the drawer cabinet 30. The drawer cover 32 has a placement platform 50 for placing the filter screen 40 on its inner side, and a mounting hole 322 for the filter screen 40 to pass through on its upper part. Specifically, the placement platform 50 includes first steps 51 on both sides and second steps 52 below the two first steps 51. The inner side of the two first steps 51 has a slot 511 to allow the filter screen 40 to be embedded on both sides. The bottom of the filter screen 40 abuts against the second step 52. The two first limiting steps 311 facilitate the sliding of the filter screen 40 and also serve as a limiting step, while the second limiting step 21 provides support.

[0038] Please refer to details. Figure 4 The drawer cabinet 30 also has a drawer bottom plate 31, a drawer back cover 33 set on the drawer bottom plate 31 and arranged side by side with the drawer cover 32, and drawer side plates 34 set on both sides of the drawer cover 32 and the drawer back cover 33. Each drawer side plate 34 has at least one roller 35 on its outer side. The rollers 35 make it easy to pull out the entire drawer cabinet 30. The rollers 35 can be set close to the drawer back cover 33, or multiple rollers can be set as needed.

[0039] Please refer to details. Figure 4 The drawer cabinet 30 is also equipped with a fan 60 to expel heat from inside. Specifically, the fan 60 is located on the drawer back cover 33; the fan 60 blows air outwards from the drawer cabinet 30. Ventilation holes 321 are elongated and evenly spaced on the drawer cover 32 to facilitate air intake, which is then expelled by the fan 60 to expel heat from inside the drawer cabinet 30. To prevent excessive dust from entering, a filter 40 is installed corresponding to the ventilation holes 321. The filter 40 filters out some dust, preventing excessive dust from affecting the components inside the drawer cabinet 30. The filter 40 is also detachable from the drawer cover 32 for easy removal and cleaning. If the filter 40 is damaged, it can be directly replaced.

[0040] Please refer to details. Figure 5 , 8 The drawer cabinet 30 has a raised first limiting step 311 at its bottom, and a second limiting step 21 is provided on the inner side of the guide rail 20. The first limiting step 311 and the second limiting step 21 prevent the drawer cabinet 30 from sliding completely out of the guide rail 20. The first limiting step 311 and the second limiting step 21 can be directly welded to a designated position as a protrusion, or formed by stamping, depending on actual needs. The first limiting step 311 is located below the drawer bottom plate 31, and the second limiting step 21 is located at the bottom inner side of the guide rail 20. The openings of the two guide rails 20 are positioned facing inwards, and the rollers 35 slide inside the guide rails 20.

[0041] Please refer to details. Figure 7 , 8 At least one buckle 22 is provided at the bottom of the guide rail 20. A corresponding locking position 111 is provided on the support plate 11 for the buckle 22. After the buckle 22 passes through the locking position 111, it latches the support part and is locked with bolts. The buckle 22 includes a connecting part 221 and a limiting part 222. The locking position 111 includes a clearance part 1111 and a locking part 1112. When the buckle 22 is engaged, the connecting part 221 is first passed through the clearance part 1111, and then the guide rail 20 is pushed so that the connecting part 221 is located inside the locking part 1112, and the limiting part 222 is located below the locking part 1112. Specifically, the lateral width of the connecting part 221 is smaller than the lateral width of the limiting part 222, and the lateral width of the locking part 1112 is smaller than the lateral width of the clearance part 1111. At the same time, the width of the clearance part 1111 needs to ensure that the clearance part 1111 can pass through, and the width of the locking part 1112 can ensure that the connecting part 221 is embedded. In this utility model, two buckles 22 are provided on any one of the guide rails 20, and two locking positions 111 are provided for each guide rail 20, so that the guide rail 20 can be better restricted on the support plate 11. At the same time, the guide rail 20 can be quickly installed on the support plate 11 with one bolt, thereby improving the installation efficiency.

[0042] Please refer to details. Figure 2 The drawer cover 32 is also equipped with a display screen 70 and a handle 80, with at least one handle 80. When two handles 80 are provided, they are arranged horizontally side by side to facilitate the pulling out of the drawer cabinet 30.

[0043] In summary, the low-voltage capacitor cabinet of this utility model improves heat dissipation by providing ventilation holes on the drawer cover to allow air to enter from the outside of the cabinet. At the same time, the filter screen can effectively prevent most dust from entering, which can improve the service life of the low-voltage capacitor cabinet. In addition, the first limiting step and the second limiting step can prevent the drawer cabinet from sliding completely out of the guide rail, avoiding the drawer cabinet falling and causing injury to the user.
