Description

Technical Field

[0001] This utility model relates to the field of electrical components technology, specifically a quick-assembly and disassembly capacitor structure. Background Technology

[0002] Currently, most large or extra-large bolt-type electrolytic capacitors on the market are fixed with clamps. After inspection to ensure the capacitor is free of deformation and the explosion-proof valve is intact, EVA tape is first wrapped around the area where the clamp will be installed. This prevents damage to the capacitor casing when tightening the clamp. Then, the capacitor is adjusted to the appropriate position according to the positive and negative markings on the fixture, ensuring the screw holes are aligned. The clamp is then placed on the capacitor and the screws are tightened to secure it. The capacitor is then removed and placed properly. Finally, the capacitor is installed in the designated position through the screw holes extending from the clamp. Because the installation requires wrapping with tape before installation and a large number of screws during installation, the process is quite cumbersome and affects work efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a quick-assembly and disassembly capacitor structure, which simplifies capacitor installation and improves work efficiency.

[0004] The technical solution is as follows: a quick-release capacitor structure includes a mounting plate on which capacitors are disposed. The capacitors are arranged side-by-side, with the positive and negative terminals of adjacent rows connected by a busbar. An insulating support post is provided between adjacent capacitors, and the busbar has through holes corresponding to the insulating support post. Insulating paper is placed above the busbar, and two copper electrode busbars are disposed on the insulating paper. Screws penetrating the insulating paper are disposed on the copper electrode busbars, and the screws are connected to the insulating support post to press the capacitors firmly onto the mounting plate.

[0005] A further feature is that the bottom of the insulating support column is connected to a lower support column, and the lower support column is fixed to the mounting plate;

[0006] A heat sink is installed at the bottom of the mounting plate. A through hole corresponding to the capacitor is opened on the mounting plate. A silicone thermal conductive sheet is placed in the through hole. The upper end face of the silicone thermal conductive sheet abuts against the bottom of the capacitor and the lower end face abuts against the upper end face of the heat sink.

[0007] Each of the capacitors is connected to an equalizing resistor.

[0008] By adopting this utility model, the use of tape wrapping and a large number of screws is eliminated. The capacitor is directly pressed and fixed by the electrode copper busbar, which prevents it from shifting due to vibration, simplifies the installation of the capacitor and improves work efficiency.

[0016] See Figures 1-7 As shown, a quick-assembly and disassembly capacitor structure includes a mounting plate 1, on which capacitors 2 are disposed. In this embodiment, there are twelve capacitors arranged in three rows side by side. The positive and negative terminals of adjacent rows of capacitors 2 are connected by busbars 3, which is equivalent to four groups of parallel capacitors. Each group is formed by three capacitors 2 connected in series. An insulating support column 4 is disposed between adjacent capacitors 2, and a through hole 5 corresponding to the insulating support column 4 is opened on the busbar 3. The bottom of the insulating support column 4 is connected to a lower support column 6, and the lower support column 5 is fixed to the mounting plate 1.

[0017] An insulating paper 7 is installed above the busbar 3. Two copper electrode busbars 8 are installed on the insulating paper 7, which lead out the positive and negative terminals of the capacitor respectively. A screw (not shown in the figure) is installed on the copper electrode busbar 8 that penetrates the insulating paper 7. A threaded hole is opened at the top of the insulating support column 4. The screw is connected to the insulating support column 4 to press the capacitor 2 tightly against the mounting plate 1.

[0018] A heat sink 9 is installed at the bottom of the mounting plate 1. The mounting plate 1 has through holes 10 corresponding to the capacitors. A silicone thermal pad 11 is installed in the through hole 10. The size of the through hole 10 is slightly larger than the outer diameter of the silicone thermal pad 11. The upper end face of the silicone thermal pad 11 abuts against the bottom of the capacitor 2, and the lower end face abuts against the upper end face of the heat sink 9. The silicone thermal pad 11 can not only effectively buffer the height difference between the capacitor 2 and the busbar 3 and the mounting plate 1, but also prevent the bottom of the capacitor from directly contacting the smooth surface of the heat sink 9, so that it will not be displaced.

[0019] To improve the voltage withstand capability of the capacitors and meet the requirements of high-voltage applications, each capacitor 2 is connected to a voltage equalization resistor 12.

[0020] The capacitor in this application uses Wuxi-made burning tape, which does not require clamps for connection and a large number of screws for fixing. This eliminates the tedious disassembly and assembly process, simplifies operation, and improves work efficiency. Moreover, the capacitor is pressed and fixed by the electrode copper busbar, which avoids the capacitor from shifting due to vibration during operation.
