Description

Technical Field

[0001] The invention relates to the technical field of capacitors, and in particular to a modular combined capacitor. Background Art

[0002] Existing capacitors can be combined in quantity according to their own power factor compensation needs, but some single capacitors are heavy, which brings challenges to the installation, maintenance and expansion of capacitors. Because single capacitors are heavy, the position of capacitors needs to be constantly adjusted during the installation of multiple groups of capacitors to ensure that each connection part can be accurately aligned, which makes the whole process time-consuming and inefficient. Therefore, a modular combination capacitor is urgently needed to solve this problem. Summary of the invention

[0003] The present invention aims at the deficiencies in the prior art and provides the following technical solutions:

[0004] Modular combination capacitors, including:

[0005] Multiple groups of capacitor bodies;

[0006] A connection structure, the connection structure comprising a clamping assembly respectively arranged on both sides of the capacitor body and a clamping assembly adapted to the clamping assembly;

[0007] Mounting feet, a first mounting foot is provided at the bottom of the capacitor body and below the clamping assembly, a second mounting foot is provided at the bottom of the capacitor body and below the clamping assembly, and a cavity is provided on the second mounting foot for the first mounting foot to be embedded and limited;

[0008] When installing two adjacent groups of capacitor bodies, the snap-in assembly and the first mounting foot of one group of the capacitor bodies are controlled to align with the snap-in assembly and the second mounting foot of the other group of the capacitor bodies and then plugged vertically downward, so that the snap-in assembly is embedded in the snap-in assembly while the second mounting foot is embedded in the first mounting foot, thereby realizing a vertical plugging action and installing the two adjacent groups of capacitor bodies in place.

[0009] As an improvement of the above technical solution, the capacitor body includes a capacitor body and an end cover arranged on the capacitor body, and the clamping assembly and the clamping assembly are respectively arranged on both sides of the end cover.

[0010] As an improvement of the above technical solution, the first mounting foot and the clamping assembly are staggered with each other in the vertical direction, and the second mounting foot and the clamping assembly are staggered with each other in the vertical direction.

[0011] As an improvement of the above technical solution, the clamping assembly includes two groups of clamping sleeves and a concave block arranged between the two groups of clamping sleeves. The clamping assembly includes two groups of T-shaped clamping blocks corresponding to the positions of the clamping sleeves and an insert block arranged between the two groups of T-shaped clamping blocks.

[0012] As an improvement of the above technical solution, a first connecting hole is provided on the mounting foot one, and a second connecting hole is provided on the mounting foot two. When the mounting foot one is embedded in the mounting foot two, the first connecting hole and the second connecting hole correspond one to one and are locked by threaded fasteners.

[0013] As an improvement of the above technical solution, the mounting foot 2 is provided with a guide area, a limit area, a locking area and a redundant area from top to bottom, and the mounting foot 1 enters the guide area, the limit area and the locking area in sequence, and finally the mounting foot 1 is limited by the locking area.

[0014] As an improvement of the above technical solution, the width of the guide area gradually decreases from top to bottom, the width of the limiting area is consistent with the minimum width of the guide area, the width of the locking area gradually decreases from top to bottom, the maximum width of the locking area is consistent with the width of the limiting area, and the width of the redundant area is consistent with the minimum width of the locking area.

[0015] Beneficial effects of the present invention:

[0016] During the installation process, only one vertical plug-in action is required to simultaneously connect multiple components. When the snap-on component is embedded in the snap-fit ​​component, the first mounting foot is also inserted into the second mounting foot. The two fit tightly together to complete the installation process. In this way, when the capacitor body is assembled, each connection part can be locked and limited at the same time, which not only ensures the docking of the snap-on component and the snap-fit ​​component, but also allows the first mounting foot and the second mounting foot to be in place in one step. The whole process is efficient and easy to repeat. This installation method shows high flexibility in the combination application scenarios of the capacitor body and meets the needs of different numbers of combinations.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] A modular combined capacitor comprises: a plurality of capacitor bodies, a connection structure and mounting feet 30;

[0025] The capacitor body includes a capacitor body 10 and an end cover 20 disposed on the capacitor body 10.

[0026] The connecting structure includes a snap-on assembly respectively arranged on both sides of the end cover 20 and a snap-on assembly adapted to the snap-on assembly, the snap-on assembly includes two groups of ferrules 21 and a concave block 22 arranged between the two groups of ferrules 21, and the snap-on assembly includes two groups of T-shaped blocks 23 corresponding to the positions of the ferrules 21 and an insert block 24 arranged between the two groups of T-shaped blocks 23.

[0027] refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4When multiple groups of capacitor bodies 10 need to be spliced, one group of capacitor bodies 10 is lifted by a crane and observed from the top to ensure that the positions of the clamping sleeve 21 and the T-shaped clamping block 23 are accurately aligned, or the concave block 22 and the plug block 24 are correctly aligned. Then, when the capacitor body 10 slowly moves downward, the clamping assembly on its end cover 20 gradually approaches the clamping assembly on the end cover 20 of another group of capacitor bodies 10. Since the clamping sleeve 21 is open at the bottom and has a storage space for accommodating the T-shaped clamping block 23, when observed from the top, as the capacitor body 10 moves downward, the clamping assembly on the end cover 20 gradually approaches the clamping assembly on the end cover 20 of the other group of capacitor bodies 10. As the capacitor body 10 continues to move downward, the sleeve 21 can gradually wrap the T-shaped block 23 until the block 23 is embedded in the sleeve 21, and the two limit each other. At the same time, the concave block 22 gradually approaches the plug-in block 24 as the capacitor body 10 moves downward. The concave block 22 is also open at the bottom, and its internal shape is adapted to the shape of the plug-in block 24. The concave block 22 is gradually sleeved on the plug-in block 24 until the plug-in block 24 is completely embedded in the concave block 22. The two limit each other, so that the end covers 20 of the two adjacent groups of capacitor bodies 10 can be firmly limited in the plane.

[0028] A mounting foot 30, a mounting foot 1 31 is provided at the bottom of the capacitor body 10 and below the clamping assembly, a mounting foot 2 32 is provided at the bottom of the capacitor body 10 and below the clamping assembly, and a cavity is provided on the mounting foot 2 32 for the mounting foot 1 31 to be embedded and limited;

[0029] Specifically, refer to Figure 1 as well as Figure 5 When the snap-on assembly and the snap-fit ​​assembly are installed, the mounting foot 1 31 is also embedded in the mounting foot 2 32 to achieve installation. Therefore, through a single vertical plug-in action, not only the docking of the snap-on assembly and the snap-fit ​​assembly is achieved, but also the mounting foot 1 31 and the mounting foot 2 32 are installed in place at the same time, ensuring that all docking parts can complete locking and limiting at the same time, greatly simplifying the installation process and improving the reliability of the connection.

[0030] In order to avoid interference between components during the splicing process, refer to Figure 2 In one embodiment, the first mounting foot 31 and the snap-fit ​​assembly are staggered with each other in the vertical direction, and the second mounting foot 32 and the snap-fit ​​assembly are staggered with each other in the vertical direction.

[0031] In one embodiment, a first connecting hole is formed on the mounting foot 1 31, and a second connecting hole is formed on the mounting foot 2 32. When the mounting foot 1 31 is embedded in the mounting foot 2 32, the first connecting hole and the second connecting hole correspond one to one and are locked by threaded fasteners. After the vertical plug-in action is completed and the components are initially in place, threaded fasteners are used to pass through the first connecting hole and the second connecting hole and tighten them, so that a more secure connection relationship is formed between the mounting foot 1 31 and the mounting foot 2 32.

[0032] In one embodiment, reference Figure 5 The second mounting foot 32 is provided with a guide area 321, a limit area 322, a locking area 323 and a redundant area 324 from top to bottom in sequence. The first mounting foot 31 enters the guide area 321, the limit area 322 and the locking area 323 in sequence, and finally the locking area 323 limits the first mounting foot 31. The width of the guide area 321 decreases gradually from top to bottom, and the width of the limit area 322 is consistent with the minimum width of the guide area 321. The width of the locking area 323 decreases gradually from top to bottom, and the maximum width of the locking area 323 is consistent with the width of the limit area 322. The width of the redundant area 324 is consistent with the minimum width of the locking area 323.

[0033] Specifically, when the installation foot 31 is inserted into the guide area 321, its wide upper opening provides a large tolerance space for it, which is convenient for initial alignment. As the installation foot 31 gradually goes deeper, the gradually narrowing width plays a guiding role, allowing it to naturally adjust toward the center position, ensuring the accuracy of subsequent entry into the limiting area 322. The width of the limiting area 322 is consistent with the minimum width of the guide area 321, forming a stable channel. After the installation foot 31 enters, it is strictly restricted in the horizontal direction to prevent it from shaking left and right, thereby ensuring the stability of the installation foot 31 during the vertical downward movement. It can only continue to descend along the predetermined vertical direction. As the mounting foot 31 enters, the locking area 323 gradually tightens the wrapping of the mounting foot 31 in the vertical direction, firmly locks the mounting foot 31, and limits its displacement in all directions, ensuring that the mounting foot 31 will not easily fall off even when subjected to external force impact. Although the redundant area 324 does not directly play a key role in the limiting process of the mounting foot 31, it reserves a certain amount of space for possible installation errors, thermal expansion and contraction of materials, etc., further enhancing the adaptability and reliability of the entire installation structure, and ensuring the long-term stable operation of the capacitor combination.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
