Description

Technical Field

[0001] This application relates to the technical field of power systems, and in particular to a capacitor bank. Background Technology

[0002] Capacitor banks are a very common type of equipment in power systems. They can be used to improve power quality. Their working principle is to provide reactive power compensation by connecting appropriate capacitors, thereby improving the power factor.

[0003] In related technologies, a capacitor bank includes a cabinet and capacitors. The cabinet is equipped with a front support rod and a rear support rod. The front support rod is located near the front side of the cabinet, and the rear support rod is located near the rear side of the cabinet. One end of the capacitor is connected to the front support rod by bolts, and the other end is connected to the rear support rod by bolts.

[0004] However, when the capacitors need to be disassembled during use, the staff must first remove the bolts on the front support rod and then move to the rear of the cabinet to remove the bolts on the rear support rod. The disassembly and assembly steps are complicated and inconvenient, and therefore need to be improved. Utility Model Content

[0005] To simplify the capacitor assembly and disassembly process and improve assembly and disassembly efficiency, this application provides a capacitor cabinet.

[0006] The capacitor bank provided in this application adopts the following technical solution:

[0007] A capacitor bank includes a cabinet and capacitors. The cabinet has a front support rod and a rear support rod, the front support rod being near the front side of the cabinet and the rear support rod near the rear side of the cabinet. The cabinet has a quick-connect structure for detachably connecting the capacitors. The quick-connect structure includes a connector and a limiting block on the connector. The connector is detachably mounted on either the front or rear support rod. The limiting block has a limiting groove for one end of the capacitor to extend into. An elastic element for pressing against the capacitor is provided in the limiting groove. A stop element for preventing the capacitor from moving out of the limiting groove is provided on the limiting block.

[0008] By adopting the above technical solution, when installing the capacitor, simply move the capacitor towards the limiting groove until it extends into the groove. After insertion, the elastic element will undergo elastic deformation and press against the capacitor, while the stop element will prevent the capacitor from moving out of the limiting groove, thus helping to improve the stability of the capacitor.

[0009] When it is necessary to remove the capacitor, simply move the capacitor out of the limiting slot. The above operation can be carried out on one side of the cabinet without having to alternately move to the front and back sides of the cabinet and turn the bolts. The disassembly and assembly process is simple and efficient.

[0010] Optionally, the stop includes a stop block slidably disposed in the limiting block and a stop spring for driving the stop block to move closer to the capacitor. The stop spring is connected between the stop block and the limiting block, and the extension and retraction direction of the stop spring is perpendicular to the insertion direction of the capacitor.

[0011] By adopting the above technical solution, when the capacitor is inserted into the limiting groove, the spring force of the stop spring will cause the stop block to abut against the capacitor, making it difficult for the capacitor to move out of the limiting groove.

[0012] Optionally, the stop block has a guide slope at one end near the capacitor, which is used to guide the stop block away from the limit groove when the capacitor is inserted into the limit groove.

[0013] By adopting the above technical solution, during the process of inserting the capacitor into the limiting groove, the capacitor will contact the guide slope and press against the stop block, causing the stop block to automatically move away from the limiting groove. With this design, when installing the capacitor, the operator does not need to manually move the stop block away from the limiting groove simultaneously, simplifying the operation.

[0014] Optionally, the limiting block is provided with a stop groove that slides with the stop block. Both the stop groove and the stop block have trapezoidal cross sections, and the stop spring is fixedly connected to the groove wall of the stop groove away from the limiting groove.

[0015] By adopting the above technical solution, both the stop block and the stop groove have trapezoidal cross-sections, which ensures that the stop block is confined in the stop groove and is not easily dislodged, resulting in high movement stability. In addition, the sliding fit between the stop block and the stop groove also prevents the stop spring from deforming in a direction perpendicular to its own extension and contraction due to the force of the capacitor, which helps maintain the elasticity of the stop spring and extend its service life.

[0016] Optionally, the elastic element includes a rubber pad detachably disposed in the limiting groove. A plurality of positioning structures are provided between the rubber pad and the limiting block. The positioning structure includes a positioning block and a positioning groove that are interlocked. The positioning block is disposed on the side wall of the rubber pad, and the positioning groove is formed on the groove wall of the limiting groove.

[0017] By adopting the above technical solution, the rubber pad is connected to the limiting block through the cooperation of the positioning block and the positioning groove, which has the advantages of simple structure and convenient assembly and disassembly. When the rubber pad wears out after long-term use, it can be removed directly without replacing the entire quick-connect structure, which is simple to operate and saves costs. When the capacitor is inserted into the limiting groove, the capacitor will squeeze the rubber pad, making the rubber pad and the limiting block more tightly connected, and the friction between the capacitor and the rubber pad is large, which enhances the limiting effect of the quick-connect structure on the capacitor.

[0018] Optionally, the connector includes a connecting block, two mounting blocks disposed opposite each other on the same side of the connecting block, and extension blocks disposed on the side of the two mounting blocks close to each other. A connecting hole is formed between the connecting block, the mounting blocks, and the extension blocks, and the front support rod and the rear support rod pass through the connecting hole.

[0019] By adopting the above technical solution, when assembling the quick-connect structure with the front or rear support rod, the front or rear support rod can be directly inserted into the connecting hole. Furthermore, the connector can slide relative to the front or rear support rod. By adjusting the position of the connector on the front or rear support rod, the distance between two adjacent quick-connect structures can be increased, thereby increasing the spacing between adjacent capacitors and improving heat dissipation.

[0020] Optionally, a connecting bolt is provided on the connecting block, and connecting bolt holes that are threaded to the connecting bolt are provided on the front support rod and the rear support rod.

[0021] By adopting the above technical solution, the connecting bolts can lock the connecting block on the front support rod or the rear support rod, thereby improving the stability of the connector and the capacitor; and the connecting bolts are detachable, which facilitates the quick-connect structure to be disassembled and assembled.

[0022] Optionally, multiple crossbeams of different heights are respectively provided on the opposite side walls of the cabinet, and fastening bolts that can be detachably connected to the front support rod or the rear support rod are passed through the crossbeams.

[0023] By adopting the above technical solution, the two ends of the front support rod and the rear support rod are respectively connected to the crossbeams on different side walls of the cabinet. When the capacitor needs to be installed at different heights in the cabinet, simply remove the fastening bolts on the front support rod or the rear support rod to separate the front support rod or the rear support rod from the original crossbeam. Then, fix the front support rod or the rear support rod to the crossbeam at another height with the fastening bolts to change the position of the capacitor.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application enables quick assembly and disassembly of capacitors by incorporating a quick-connect structure within the capacitor cabinet. Compared to the traditional method of connecting capacitors with bolts, this method offers advantages such as simpler assembly and disassembly processes and higher efficiency.

[0026] 2. When the capacitor is installed in the quick-connect structure, the stop can prevent the capacitor from separating from the quick-connect structure, making the installation of the capacitor more stable;

[0027] 3. When the capacitor is inserted into the limiting groove, the rubber pad will abut between the capacitor and the limiting groove, making the quick-connect structure have a better limiting effect on the capacitor. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a capacitor bank.

[0037] Reference Figure 1 A capacitor cabinet includes a cabinet body 1 and a capacitor 2 detachably disposed in the cabinet body 1. In this embodiment, the cabinet body 1 includes a front door 11 and a rear door 12. Both the front door 11 and the rear door 12 can be opened or closed when disassembling or assembling the capacitor 2, so as to facilitate the removal of the capacitor 2 from the front or rear side of the cabinet body 1. In other embodiments, a door can be provided only on one side of the cabinet body 1, as long as the disassembly and assembly of the capacitor 2 can be achieved.

[0038] Reference Figure 1Multiple crossbeams 15 of varying heights are installed on opposite side walls of cabinet 1. Two crossbeams 15 at the same height on different side walls are connected by a front support rod 13 and a rear support rod 14. The front support rod 13 is located near the front of cabinet 1, and the rear support rod 14 is located near the rear of cabinet 1. Fastening bolts 16, detachably connected to either the front or rear support rod 13, pass through the crossbeams 15. The bottom ends of capacitor 2 are respectively mounted on the front and rear support rods 13 and 14. When it is necessary to fix capacitor 2 at different heights, simply remove the fastening bolts 16 to move the front or rear support rod 13 to connect with the crossbeams 15 at different heights, thereby fixing capacitor 2 at different heights.

[0039] Reference Figure 2 Both the front support rod 13 and the rear support rod 14 are equipped with quick-connect structures 3 for detachably connecting the capacitor 2. The quick-connect structure 3 includes a connector 31 and a limiting block 32 integrally formed on the connector 31. The connector 31 is detachably mounted on either the front support rod 13 or the rear support rod 14. The limiting block 32 has a limiting groove 321 with an upper opening, allowing one end of the capacitor 2 to extend vertically into it. By providing quick-connect structures 3 on the front support rod 13 and the rear support rod 14, the capacitor 2 can be quickly assembled and disassembled. When assembling or disassembling the capacitor 2, only one end of the capacitor 2 needs to be inserted into or removed from the limiting groove 321, simplifying the assembly and disassembly process.

[0040] Reference Figure 2 and Figure 3 An elastic element 33 for pressing against the capacitor 2 is provided in the limiting groove 321. The elastic element 33 includes a rubber pad 331 detachably disposed in the limiting groove 321. Several positioning structures 34 are provided between the rubber pad 331 and the limiting block 32. The positioning structure 34 includes a positioning block 341 and a positioning groove 342 that are inserted into each other. The positioning block 341 is integrally formed on the side wall of the rubber pad 331, and the positioning groove 342 is formed on the groove wall of the limiting groove 321. The rubber pad 331 can undergo elastic deformation, and the positioning block 341 extends into the positioning groove 342, which increases the stability of the connection between the rubber pad 331 and the limiting block 32, making it difficult for the rubber pad 331 to fall out of the limiting groove 321.

[0041] Reference Figure 4 The connector 31 includes a connecting block 311, two mounting blocks 312 fixed on the same side of the connecting block 311, and extension blocks 313 fixed on the sides of the two mounting blocks 312 respectively. A connecting hole 314 is formed between the connecting block 311, the mounting blocks 312, and the extension blocks 313. The front support rod 13 and the rear support rod 14 are respectively inserted into the connecting holes 314 formed by the different connectors 31. When installing the quick-connect structure 3, it is only necessary to insert the front support rod 13 and the rear support rod 14 into the connecting hole 314, which is simple to operate.

[0042] Reference Figure 2 The connecting block 311 is provided with a connecting bolt 315, and the front support rod 13 and the rear support rod 14 are both provided with connecting screw holes 316 that are threaded to the connecting bolt 315. The number of connecting screw holes 316 is greater than the number of connecting bolts 315, so that the position of the connecting block 311 locked to the front support rod 13 or the rear support rod 14 by the connecting bolt 315 is adjustable.

[0043] Reference Figure 3 and Figure 4 To enhance the limiting effect of the quick-connect structure 3 on the capacitor 2, the limiting block 32 is provided with a stop 35 to prevent the capacitor 2 from moving out of the limiting groove 321. The stop 35 includes a stop block 351 slidably disposed in the limiting block 32 and a stop spring 353 for driving the stop block 351 to move closer to the limiting groove 321. The extension and contraction direction of the stop spring 353 is perpendicular to the insertion direction of the capacitor 2.

[0044] Reference Figure 3 and Figure 5 The limiting groove 321 has a horizontally extending stop groove 354 on its groove wall. The stop block 351 is slidably disposed in the stop groove 354, and both the stop block 351 and the stop groove 354 have trapezoidal cross sections. The stop spring 353 is connected between the stop block 351 and the groove wall of the stop groove 354 away from the limiting groove 321. The end of the stop block 351 near the limiting groove 321 has a guide slope 352. When the capacitor 2 is inserted into the limiting groove 321, the capacitor 2 will contact the guide slope 352 and press the stop block 351, so that the stop block 351 automatically moves away from the limiting groove 321, making it convenient to install and remove the capacitor 2.

[0045] The implementation principle of a capacitor cabinet according to an embodiment of this application is as follows: When installing capacitor 2, first, the front support rod 13 and the rear support rod 14 are respectively inserted into the connection holes 314 of different quick-connect structures 3, and then the connecting bolts 315 are tightened to connect the quick-connect structure 3 to the front support rod 13 or the rear support rod 14. Then, the two ends of the front support rod 13 and the rear support rod 14 are respectively connected to the crossbeams 15 located at the same height on both sides of the cabinet 1. Finally, the capacitor 2 is vertically inserted into the limiting groove 321. At this time, the capacitor 2 will be pressed tightly by the rubber pad 331 and the stop block 351, resulting in high stability. When it is necessary to remove capacitor 2, simply stand on one side of the cabinet 1 and pull the capacitor 2 upward with force to move the capacitor 2 out of the limiting groove 321. The above removal method can be carried out on one side of the cabinet 1 without alternating between the two sides of the cabinet 1 and turning the bolts. The disassembly and assembly process is simple and efficient.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
