Description

Technical Field

[0001] This utility model relates to the field of power capacitor technology, and in particular to an integrated power capacitor. Background Technology

[0002] A capacitor is an electronic component that stores electrical energy by accumulating charge between two conductors. These two conductors are typically called electrodes, and an insulating layer called a dielectric exists between them. When a voltage is applied to the plates of a capacitor, positive charges accumulate on one plate and negative charges on the other, thus storing energy under the influence of an electric field. Integrated power capacitors typically refer to multiple capacitors combined in a specific way to meet the requirements of a particular application regarding capacitance, size, weight, and performance. This integration can be achieved in various ways, including parallel, series, or hybrid connections, as well as by employing special packaging technologies to improve the overall performance and reliability of the capacitor bank.

[0003] Traditional integrated power capacitors consist of dielectric material, electrode material, and terminals. When a voltage is applied between the capacitor plates, positive charges accumulate on one electrode, and negative charges accumulate on the other. Due to the insulating properties of the dielectric, these charges do not flow directly through the dielectric but instead generate an electric field on the electrode surface. This electric field stores energy until the capacitor is discharged or the voltage drops to zero.

[0004] Traditional integrated power capacitors require multiple parts for fixation and specialized tools for disassembly, increasing the number of steps and operations involved and reducing work efficiency. To address this issue, an integrated power capacitor is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-4 An embodiment of this utility model is provided: an integrated power capacitor, including a mounting plate 1, a lower outer shell 2 fixedly connected to the upper surface of the mounting plate 1, a mounting plate 6 inside the lower outer shell 2, a capacitor body 5 fixedly connected to the upper surface of the mounting plate 6, a fixing mechanism inside the mounting plate 6 for mounting and fixing the capacitor body 5, and a protective component on the side wall of the lower outer shell 2 for protecting the capacitor body 5.

[0036] The fixing mechanism includes a mounting housing 7, a sliding rod 8 slidably connected inside the mounting housing 7, a handle 9 fixedly connected to one end of the sliding rod 8, a fixing ring 10 fixedly connected inside the mounting housing 7, a side wall of the sliding rod 8 slidably connected inside the fixing ring 10, a first spring 11 sleeved on the side wall of the sliding rod 8, a fixing block 12 fixedly connected to the other end of the sliding rod 8, a push plate 13 fixedly connected inside the fixing block 12, a fixing column 14 fixedly connected inside the mounting housing 7, a locking block 15 rotatably connected to the side wall of the fixing column 14, the side wall of the locking block 15 abutting against the side wall of the push plate 13, one end of the first spring 11 fixedly connected to the side wall of the sliding rod 8, the other end of the first spring 11 fixedly connected to the side wall of the fixing ring 10, the side wall of the fixing block 12 slidably connected inside the mounting housing 7, the side wall of the mounting housing 7 slidably connected inside the lower housing 2, and the side wall of the locking block 15 slidably connected inside the lower housing 2.

[0037] When disassembling the capacitor body 5 using this equipment, firstly, grasp handle 9 and press down. This action causes the slide bar 8 to descend, compressing the first spring 11 and putting it under tension. Subsequently, the fixing block 12 slides downwards driven by the slide bar 8. At this moment, the push plate 13 pushes the locking block 15, causing it to rotate. As the locking block 15 rotates, it gradually disengages from the inside of the lower outer casing 2, releasing the lock on the mounting plate 6. In this way, the originally fixed capacitor body 5 is no longer restricted and can be removed, completing the disassembly process. The easy-to-install and disassemble capacitor can significantly reduce the overall disassembly time, improve work efficiency, reduce the risk of workers coming into contact with live parts, and improve work safety. The easy-to-install and disassemble design improves the efficiency and safety of maintenance work and ensures the continuous and stable operation of the power system.

[0038] Reference Figures 5-6 The protective assembly includes an upper outer shell 3, the side wall of which is rotatably connected to the side wall of the lower outer shell 2. A heat dissipation plate 4 is provided inside the upper outer shell 3. A second locking block 17 is fixedly connected to the side wall of the upper outer shell 3. A sleeve 16 is fixedly connected to the side wall of the lower outer shell 2. The side wall of the second locking block 17 is slidably connected to the inside of the sleeve 16. A fixing sleeve 18 is fixedly connected to the side wall of the sleeve 16. A pressing rod 19 is slidably connected inside the fixing sleeve 18. A second spring 21 is sleeved on the side wall of the pressing rod 19. One end of the second spring 21 is fixedly connected to the inside of the fixing sleeve 18, and the other end of the second spring 21 is fixedly connected to the side wall of the pressing rod 19. A second handle 20 is fixedly connected to one end of the pressing rod 19, and a third locking block 22 is fixedly connected to the other end of the pressing rod 19. The side wall of the third locking block 22 is slidably connected to the inside of the sleeve 16, and the side wall of the third locking block 22 is slidably connected to the inside of the second locking block 17.

[0039] To enhance the connection stability and protective performance between the upper outer shell 3 and the lower outer shell 2, when the upper outer shell 3 is attached to and slides down the side wall of the lower outer shell 2, this action guides the second locking block 17 to slide into the inner cavity of the sleeve 16 along a preset trajectory. During the sliding process, the edge of the second locking block 17 contacts the third locking block 22, causing the pressing rod 19 to move, thereby compressing the second spring 21 until the second locking block 17 is successfully embedded deep into the sleeve 16. At this time, as the second locking block 17 is fully inserted, the second spring 21 quickly returns to its original state due to the release of external pressure. Its rebound force pushes the third locking block 22 into the slot in the second locking block 17, locking the positional relationship between the upper outer shell 3 and the lower outer shell 2, ensuring that the shell is closed. In this way, the capacitor is isolated from external dust, dirt and various potential environmental pollutants. The protective cover can provide an additional insulation layer, reduce the risk of electric shock, and protect the safety of operators and equipment. The upper outer shell 3 and the lower outer shell 2 are made of wear-resistant materials, which can resist wear and impact in daily use, thereby extending the service life of the capacitor.

[0040] Working principle: When the capacitor body 5 needs to be removed during operation, firstly, press down the handle 9 to move the slide bar 8 downward, causing the first spring 11 to be compressed and contracted. Then, the fixing block 12 slides down, causing the push plate 13 to push the locking block 15 to rotate and disengage it from the lower outer shell 2. At this time, the mounting plate 6 loses its fixation, and the capacitor body 5 can be removed. By attaching the upper outer shell 3 to the side wall of the lower outer shell 2, the locking block 17 slides into the sleeve 16. During the sliding process, the locking block 17 presses against the locking block 22, causing the pressing rod 19 to slide and the second spring 21 to contract until the locking block 17 is fully inserted into the sleeve 16. At this time, the second spring 21 loses its compression and pushes the locking block 22 into the slot inside the locking block 17, thereby fixing the upper outer shell 3 and protecting the capacitor from dust, dirt and other potential environmental pollutants.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
