Description

Technical Field

[0001] This utility model relates to the field of power electronic equipment manufacturing and processing, and more specifically, to a capacitor mounting structure. Background Technology

[0002] Capacitors are essential components in power equipment such as frequency converters and inverters.

[0003] Currently, when installing capacitors into power equipment (such as frequency converters), two methods are commonly used for fixed installation. The first method involves designing a corresponding capacitor installation mold and then using a professional starter clamp to fix the capacitor and the mold together. The second method involves selecting a special capacitor with grooves and fixing it to the sheet metal part by binding it with an extended binding strap.

[0004] The above methods either require more time and money to design and manufacture molds, resulting in high costs and low efficiency, and also require additional space. Furthermore, they require pressing equipment during installation, which is inconvenient. Alternatively, they may result in insufficient bonding strength due to the high center of gravity, and may also lead to aging and cracking. Utility Model Content

[0005] In view of this, the present invention proposes a capacitor mounting structure that solves at least one or more of the above problems.

[0006] According to an embodiment of the present invention, a capacitor mounting structure includes a first fixing plate and a second fixing plate arranged horizontally. The bottom of the capacitor is fixed to the first fixing plate by a first connector, and the top of the capacitor is fixed to the second fixing plate by a second connector.

[0026] 40 hose clamp, 42 insulation piece, 100 capacitor Detailed Implementation

[0027] To make the objectives, technical solutions and advantages of this utility model clearer, the following embodiments will be used to further describe this utility model in detail.

[0028] Figure 1 A schematic diagram of a capacitor mounting structure according to an embodiment of the present invention is shown;

[0029] like Figure 1 As shown, the mounting structure includes a first fixing plate 1 and a second fixing plate 2 arranged horizontally. The bottom of the capacitor 100 is fixed to the first fixing plate 1 by a first connector, and the top of the capacitor 100 is fixed to the second fixing plate 2 by a second connector. The mounting structure also includes a third fixing plate 3 arranged horizontally between the first fixing plate 1 and the second fixing plate 2. The third fixing plate 3 is fixedly connected to the first fixing plate 1. The third fixing plate 3 has an opening suitable for placing the capacitor 100, which is suitable for fixing the capacitor 100 in the horizontal direction.

[0030] As can be seen, based on the capacitor mounting structure of this embodiment, by setting a first fixing plate 1 at the bottom of the capacitor 100 and a second fixing plate 2 at the top of the capacitor 100, the capacitor 100 is fixed between the first fixing plate 1 and the second fixing plate 2 through a first connector and a second connector, respectively, thus achieving fixation in the Z direction. By setting a horizontal third fixing plate 3 between the first fixing plate 1 and the second fixing plate 2 (for example, at the upper middle position of the capacitor 100), the third fixing plate 3 is fixed to the first fixing plate 1, and an opening is provided on the third fixing plate 3 to place the capacitor 100, thus further fixing the capacitor 100 in the X and Y directions. Preferably, the first fixing plate 1, the second fixing plate 2, and the third fixing plate 3 are made of sheet metal, and the first connector and the second connector are bolts.

[0031] Furthermore, the second fixing plate 2 includes a stacked busbar. Based on this structure, the structure of the busbar is fully utilized as one of the fixing structures, saving space.

[0032] Figure 2 This is a schematic diagram of a capacitor mounting structure according to another embodiment of the present invention;

[0033] Furthermore, such as Figure 2 As shown, the third fixing plate 3 is an L-shaped plate structure, including a first side plate 11 and a second side plate 12 opposite to each other, and a first bottom plate 13 located at the bottom. The first bottom plate 13 is fixed to the first fixing plate 1 by a third connector.

[0034] Specifically, the third connecting component is a bolt. Mounting holes are also provided on the first side plate 11 and the second side plate 12 for fixing to external components.

[0035] Furthermore, the first fixing plate 1 includes a third side plate 21 and a fourth side plate 22 arranged vertically opposite each other, and a second bottom plate 23 located at the bottom. A first extension plate 211 and a second extension plate 212 are extended above the third side plate 21 and the fourth side plate 22. The first bottom plate 13 is fixed to the first extension plate 211 and the second extension plate 212 respectively by the third connector.

[0036] Specifically, mounting holes are provided on the third side plate 21 and the fourth side plate 22 of the first fixing plate 1 for fixing to external components. Optionally, the first extension plate 211 includes two plates arranged front and rear, and the second extension plate 212 includes two plates arranged front and rear. Optionally, the third fixing plate 3 also includes a third extension plate and a fourth extension plate that extend vertically downward from its two front and rear sides, and the third extension plate and the fourth extension plate are further fastened by bolts or other connecting parts.

[0037] Furthermore, a C-shaped groove is formed on the second base plate 23 corresponding to the position of the first connector. By setting the C-shaped groove, the stress on the part of the second base plate 23 that fixes the capacitor 100 is increased. Furthermore, the C-shaped groove has a hollow structure.

[0038] Furthermore, a hose clamp 40 adapted to the outer diameter of the capacitor 100 is provided on the upper end surface of the first base plate 13. The hose clamp 40 is fixed to the third fixing plate 3 by a fourth connector, such as a bolt. This structure further limits the upper part of the capacitor 100, ensuring its fixing effect.

[0039] Furthermore, the inner wall of the hose clamp 40 is provided with a cushioning element (not shown in the figures). For example, EVA foam.

[0040] Furthermore, an insulating member 42 is provided between the first side plate 11 of the third fixing plate 3 and the capacitor 100 adjacent thereto, and an insulating member 42 is provided between the second side plate 12 of the third fixing plate 3 and the capacitor 100 adjacent thereto. For example, HGW insulating material. Based on this embodiment, insulation is provided between the capacitor 100 and the mounting structure.

[0041] Furthermore, the first base plate 13 has four openings suitable for mounting four capacitors 100. Based on this embodiment, multiple capacitors 100 can be fixed.

[0042] Furthermore, the first side plate 11, the second side plate 12, the third side plate 21, and the fourth side plate 22 are fixed to the external cabinet via a fifth connector. Through this embodiment, the mounting structure is fixed within, for example, a frequency converter cabinet, thus achieving overall structural stability.

[0043] As can be seen, based on the capacitor mounting structure of the above embodiments, the capacitor 100 is fixed in the X, Y, and Z directions by the fixing structure of the first fixing plate 1, the second fixing plate 2, and the third fixing plate 3, which ensures stability and makes it easy to install and disassemble.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
