Description

Technical Field

[0001] The utility model relates to a container-type high-voltage capacitor assembly and a mounting assembly used for the container-type high-voltage capacitor assembly. Background Art

[0002] High-voltage capacitors are typically used for series compensation of AC transmission lines in power transmission and transformation lines to improve line power limits and power system stability. They are also used in large substations to form static phase-controlled reactor-type dynamic reactive compensation devices (SVCs) to improve power quality. They are also used at the end of distribution lines to improve the power factor at the end of the line. They can also be installed at the terminals of large equipment with nonlinear loads, such as electric traction locomotives, for filtering purposes.

[0003] Since high-voltage capacitors need to be suitable for outdoor occasions on the one hand, and on the other hand, they usually need to be connected in series to adapt to the compensation in the aforementioned high-voltage transmission and transformation process, the high-voltage capacitor components are characterized by large volume and weight, which brings considerable difficulty to the transportation and installation of high-voltage capacitor components.

[0004] To address the aforementioned technical issues, Chinese utility model patent CN 220822346 U provides an auxiliary installation structure for high- and low-voltage switchgear sets. A support plate is designed specifically for the switchgear, and rollers are constructed at the bottom of the support plate. This structure allows the switchgear to be secured to the support plate using a pneumatic mechanism. The switchgear can then be removed from the support plate when the support plate, which is secured to the switchgear, is moved to a designated position. This method of transporting the switchgear using rollers and pneumatic mechanisms effectively reduces labor consumption. However, switchgear sets, particularly those for low-voltage electrical appliances, are lightweight and compact, and are primarily used indoors. Furthermore, high-voltage capacitor assemblies in outdoor locations are typically arranged in multiple series configurations due to practical needs. Their length alone can reach over 10 meters, and they require adaptive design. Therefore, transporting the capacitor assembly using a support plate and pneumatic mechanisms not only results in significant material and cost expenditures, but also inconveniences in initial positioning and transport of the capacitor assembly on the support plate, as well as secondary positioning and installation from the support plate onto the outdoor floor.

[0005] In order to overcome the difficulties and cost of secondary handling brought about by the above-mentioned utility model patents, another Chinese utility model patent CN 204497647 U provides another technical solution, that is, a symmetrical upward-opening track is arranged directly on the bottom of the capacitor cabinet, and a separate car body is designed on which a capacitor mounting bracket is installed in sequence and a downward-opening slide rail (the slide rail has rollers). Then, the capacitors and reactors are placed on their respective car bodies at intervals from each other, and the respective car bodies with capacitors and reactors are sent into the capacitor cabinet through the movement of the track. Furthermore, the hooks on the slide rails of the car body are used to achieve the coordinated installation of the car body and the cabinet. Although this arrangement can realize the connection of the capacitor and reactor to the electrical cabinet through the car body, the hook as a limiting device has limited rigidity. Therefore, during the transportation process, decoupling between electrical devices such as capacitors and / or reactors may occur, resulting in relative movement between the electrical devices, which may cause the entire capacitor group to be scrapped. Furthermore, the electrical components in this utility model patent have different sizes and are spaced far apart from each other, and special electrical connection components are also required to complete the connection between the capacitor, the inductor and the electrical cabinet.

[0006] In summary, the installation and fixed connection methods of the power device assembly provided in the prior art are not suitable for the installation, fixing and transportation of heavy outdoor power devices such as container-type ones. Utility Model Content

[0007] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the electrical cabinets described in the prior art, such as the huge material and cost consumption caused by the use of additional transport plates during transportation and installation, as well as the secondary positioning of the electrical cabinets, the inconvenience of floor installation, and the overall scrapping of the capacitor bank caused by positioning and fastening.

[0008] To address the aforementioned technical issues, the present invention provides a mounting structure for a containerized high-voltage capacitor assembly, wherein the containerized high-voltage capacitor assembly comprises a container and at least one set of high-voltage capacitor assemblies.

The mounting assembly is disposed between each cabinet of the high-voltage capacitor assembly and the inner wall of the container bottom, and is partially accommodated within the cabinet bottom indentation.

The first mounting assembly comprises a first steel structure flush with the longitudinal width edges of each cabinet of the high-voltage capacitor assembly, a second steel structure fastened to the cabinet steel structure and the first steel structure, and at least one set of roller assemblies and a flexible gasket partially accommodated within the cabinet bottom indentation. The second mounting assembly is securely connected to the inner wall of the container bottom and positioned below the corresponding first mounting assembly. The second mounting assembly comprises a third steel structure, a pair of positioning devices, and at least one pair of fastening devices disposed on the third steel structure. The first and second mounting assemblies are detachably connected, and each cabinet housing a high-voltage capacitor assembly equipped with the first mounting assembly can be moved relative to the second mounting assembly along a longitudinal direction X into the container and secured to the container using the positioning devices and fastening devices.

[0009] In some embodiments, the cabinet bottom indentations are symmetrically arranged with the same geometric dimensions on both sides of the bottom longitudinal width of each cabinet of the high-voltage capacitor assembly.

[0010] In some embodiments, the first steel structure is a flat steel or a channel steel; the second steel structure is a channel steel or an I-beam with a notch, and the notch faces the inner wall of the bottom of the container.

[0011] In some embodiments, a surface of the second steel structure that is fastened to the cabinet steel structure and the first steel structure is further provided with roller accommodating openings for accommodating at least two groups of roller assemblies.

[0012] Furthermore, the flexible gasket is located above the roller accommodating opening of the second steel structure and is in partial contact with the roller assembly.

[0013] In some embodiments, the third steel structure is a channel steel having a height beam and legs transverse to the height beam, and the third steel structure is arranged with its height beam facing the longitudinal centerline Y'.

[0014] In some embodiments, the legs of the third steel structure are fixed to the inner wall of the bottom of the container by welding.

[0015] In some embodiments, the positioning device is arranged at both ends of the third steel structure and has a positioning steel structure and a detachable positioning fastener to fasten the cabinets of the high-voltage capacitor assembly and limit the movement of the cabinets of the high-voltage capacitor assembly along the longitudinal direction X.

[0016] In some embodiments, the fastening device comprises a first fastening hole provided in the second steel structure, a second fastening hole provided in the third steel structure, and a fastener.

[0017] According to another aspect of the present invention, a containerized high-voltage capacitor assembly is provided, wherein the cabinets in the high-voltage capacitor assembly are arranged against each other to form an integrated configuration; and the high-voltage capacitor assembly can be fixedly connected to a separate container bottom plate with the aid of the mounting assembly for the containerized high-voltage capacitor assembly.

[0018] In summary, the present invention provides a mounting assembly for the containerized high-voltage capacitor assembly in a simple, feasible and low-cost manner, which is suitable for the installation, fixing and transportation of containerized heavy-duty outdoor power equipment.

[0040] The present invention is described below in conjunction with the accompanying drawings. It should be understood that the embodiments listed below are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. The accompanying drawings are provided to present multiple embodiments of the present invention, but the drawings do not have to be drawn according to the dimensions of the specific embodiments, and certain features may be enlarged, removed, or partially cut away to better illustrate and explain the disclosure of the present invention. Some components in the accompanying drawings can be repositioned according to actual needs without affecting the technical effects.

Unless otherwise indicated, the directional terms described in this specification are generally in accordance with conventional directions understood by those skilled in the art.

[0042] The terms "first," "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are used to distinguish one component from other components. The expression "substantially" allows for a reasonable range of angular deviation and does not necessarily mean complete consistency.

[0043] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0044] According to the instruction manual Figure 1 , which specifically shows a front view of a container-type high-voltage capacitor assembly according to the utility model, Figure 2-Figure 3 The other views of the containerized high-voltage capacitor assembly from different perspectives are shown. As shown in the figure, the containerized high-voltage capacitor assembly includes a container 200 and a high-voltage capacitor assembly 300 installed therein. The high-voltage capacitor assembly 300 can generally include at least one electrical cabinet and at least one group of capacitors, such as the attached Figure 1The first electrical cabinet 310, the first capacitor bank 320, and the second capacitor bank 330 are shown. Furthermore, the electrical cabinet and the capacitor bank have substantially the same three-dimensional dimensions, forming a compact, integrated configuration within the container 200. Alternatively, the containerized high-voltage capacitor assembly may be constructed with only a containerized floor and at least one electrical cabinet and at least one capacitor bank mounted thereon. Furthermore, the containerized high-voltage capacitor assembly includes a capacitor mounting assembly 100 positioned between the bottoms of the electrical cabinet and capacitor cabinet and the container floor inner wall 210. The high-voltage capacitor assembly 300 engages with the container 200 or the containerized floor via the capacitor mounting assembly 100, forming a movable connection along the longitudinal direction X of the container 200, particularly along the container floor inner wall 210. Consequently, the containerized high-voltage capacitor assembly can be directly transported to an outdoor power source in a containerized or compact, integrated configuration, simplifying transportation and avoiding secondary installation at the outdoor power source.

[0045] See attached Figure 5 , which specifically shows a non-limiting structure of the installation assembly for the container-type high-voltage capacitor assembly according to the utility model, and especially shows the state of the first assembly and the second assembly before installation. Each electrical cabinet and / or high-voltage capacitor cabinet, such as the attached Figure 1 The first electrical cabinet 310, the first capacitor group 320, and the second capacitor group 330 are each configured with a cabinet bottom indentation 110 along the longitudinal width direction Y of the high-voltage capacitor at the bottom of the cabinet. The cabinet bottom indentation 110 extends along the longitudinal direction X and passes through the cabinet bottom of each electrical cabinet and / or high-voltage capacitor cabinet. Preferably, the cabinet bottom indentation 110 can be, for example, formed by an attached Figure 5 The cabinet steel structure 111 shown reduces its width along the longitudinal direction Y toward the longitudinal centerline Y' to provide space for the capacitor mounting assembly 100. More preferably, the cabinet bottom indentation 110 can be configured to be symmetrical with respect to the longitudinal centerline Y' of the high-voltage capacitor, and furthermore, the cabinet bottom indentation 110 can have the same longitudinal length, width, and height dimensions. This facilitates the design, manufacture, and processing of the electrical cabinet and / or high-voltage capacitor cabinet, particularly the cabinet bottom indentation 110, and effectively reduces the costs of the corresponding design, manufacturing, and processing processes. Furthermore, the cabinet bottom indentation 110 can also be customized into a standardized configuration based on the power or model standard of the electrical cabinet or capacitor assembly, such as a standardized cabinet bottom indentation 110 suitable for 1500 kvar and 3000 kvar capacitors.

[0046] In a non-limiting embodiment of the mounting assembly for the container-type high-voltage capacitor assembly according to the present invention, the capacitor mounting assembly 100 is constructed to have at least one set of first mounting assemblies mechanically engaged with the cabinet bottom indentation 110 and at least one set of second mounting assemblies mechanically engaged with the container bottom inner wall 210, each of the first mounting assemblies is arranged above the corresponding second mounting assembly and can be snapped together with the second mounting assembly to form a detachable connection, and can move linearly relative to the second mounting assembly along the longitudinal direction X of the cabinet.

[0047] See attached Figure 5-6 The first mounting assembly is constructed to include a first steel structure 112 and a second steel structure 113 symmetrically arranged relative to the longitudinal centerline Y' of the high-voltage capacitor, as well as at least one set of roller assemblies 120 and a flexible gasket 123 housed in the cabinet bottom indentation 110. The first steel structure 112 is spaced a certain distance from the longitudinal centerline Y' relative to the cabinet steel structure 111 along the longitudinal direction Y, and is preferably configured to align with the outermost edges of each cabinet in the longitudinal direction Y and with the bottom edges of each cabinet in the longitudinal direction Z. More preferably, the first steel structure 112 can be, for example, a flat steel structure or a channel steel structure, so as to define, together with the cabinet steel structure 111, the cabinet bottom indentation 110 for accommodating multiple sets of roller assemblies 120.

[0048] Furthermore, the second steel structure 113 is preferably arranged in a symmetrical manner below the cabinet bottom indentation 110 defined by the cabinet steel structure 111 and the first steel structure 112, and its height side edge 1131 faces the cabinet steel structure 111 and the first steel structure 112. Thus, the height side edge 1131 of the second steel structure 113 can be connected to the bottom ends of the first steel structure 112 and the cabinet steel structure 111 along the longitudinal direction X in a mechanical manner known to those skilled in the art. Preferably, the height side edge 1131 of the second steel structure 113 is joined to the cabinet steel structure 111 and the first steel structure 112 in an integrated manner by metal fusion such as welding. More preferably, the second steel structure 113 can be a channel steel structure or an I-beam structure, and the concave opening of the second steel structure 113, such as a channel steel structure or an I-beam structure, faces the bottom inner wall 210 of the container to provide a sliding installation portion for the first mounting assembly relative to the second mounting assembly.

[0049] In a specific embodiment of the present invention, the height side edge 1311 of the second steel structure 113 is further provided with a roller receiving opening that can accommodate at least two groups of roller assemblies 120, so that each of the roller assemblies 120 can partially pass through the roller receiving opening and roll in contact with the second mounting assembly. Figure 1, Attachment Figure 2 , Attachment Figure 8 -Attached Figure 10 The roller receiving opening of the second steel structure 113 may be further provided with a flexible gasket 123 that contacts the rolling component of the roller assembly 120 to relieve the load applied by the cabinet to the roller, see the attached Figure 7 .

[0050] From the attached Figure 6 and attached Figure 7 As can be seen in the figure, the roller assembly 120 comprises at least a roller shaft 121 and a roller 122, wherein the roller shaft 121 is arranged transversely between the first steel structure 112 and the cabinet steel structure 111 along the longitudinal direction X of the cabinet, and can roll relative to the first steel structure 112 and the cabinet steel structure 111. More preferably, the roller shafts 121 are evenly distributed along the longitudinal direction X of the cabinet, and can be particularly arranged near the longitudinal end edges of the cabinet, so as to achieve relative movement of the electrical cabinet and / or the high-voltage capacitor assembly 300 relative to the second mounting assembly, i.e., the bottom inner wall 210 of the container, along the longitudinal direction X, by means of the first mounting assembly. For details, see the attached figure. Figure 8 Furthermore, the roller 122 is preferably a rolling bearing.

[0051] See attached Figure 5-6 The second mounting assembly comprises a third steel structure 130 directly fixed to the inner wall 210 of the container bottom, as well as a pair of positioning devices 140 and at least one pair of fastening devices 150 disposed on the third steel structure 130. The third steel structure 130 is preferably an I-beam or channel steel structure. In a specific embodiment of the present invention, the third steel structure 130 is a channel steel structure and is arranged with its height edge 1301 facing the longitudinal width centerline Y'. This positions the load-bearing center of the third steel structure 130 closer to the center of gravity of the cabinet, thereby more effectively supporting the load of the containerized high-voltage capacitor assembly and effectively reducing stress concentration. As a result, the rollers 122 of each roller assembly 120 in the first mounting assembly partially pass through the flexible gasket 123 and the roller receiving opening, and roll in contact with the outer surface of the leg transverse to the height edge 1301 of the third steel structure 130.

[0052] See also Figure 8 and Figure 9, the positioning devices 140 are respectively arranged at both ends of the third steel structure 130, and are spaced apart from each other by the longitudinal length of an electrical cabinet and / or capacitor cabinet, so as to limit the movement of the cabinet connected to the first mounting assembly relative to the third steel structure 130 along the longitudinal direction X. The positioning device 140 also has a positioning steel structure 141 arranged along the longitudinal direction X of the cabinet and a detachable positioning fastener 142. Preferably, the positioning steel structure 141 spans the longitudinal width of the cabinet, so as to limit the position of the cabinet on the inner wall 210 of the bottom of the container. The detachable positioning fastener 142 is preferably a bolt connection arranged on the positioning steel structure 141, so that the positioning steel structure 141 is fastened together with the third steel structure 130. More preferably, in a specific embodiment according to the present invention, the positioning steel structure 141 is an angle steel structure, so that the cabinet can be thrusted along the longitudinal direction X by means of the end face of the angle steel.

[0053] See also Figure 10 The fastening device 150 belonging to the second mounting assembly includes a pair of first fastening holes 151 arranged on the longitudinal surface of the second steel structure 113 and a pair of second fastening holes 152 arranged on the third steel structure 130, wherein after the movement of the cabinet in the longitudinal direction X is limited by the positioning device 140, the axial centers of the first fastening holes 151 and the corresponding second fastening holes 152 coincide with each other, so that the operator can use fasteners to achieve a fastened connection between the cabinet and the third steel structure 130 through the first fastening holes 151 of the second steel structure 113 and the corresponding second fastening holes 152 of the third steel structure 130, so that the electrical cabinet 300 installed in the container 200 can be stably fixed in the container.

[0054] On the other hand, the containerized high-voltage capacitor assembly according to the present invention can also be further constructed as shown in the attached figure. Figure 4 The arrangement shown is to first construct at least one pair of back-to-back capacitor combinations, such as a back-to-back combination of the first group of capacitors 320 and the second group of capacitors 330, and / or a back-to-back combination of the third group of capacitors 350 and the fourth group of capacitors 360; and an electrical cabinet combination adapted to the aforementioned capacitor combination, such as a back-to-back combination of the first electrical cabinet 310 and the second electrical cabinet 340, thereby further expanding the reactive power of the containerized high-voltage capacitor assembly to accommodate a wider range of outdoor applications of high-voltage capacitors.

[0055] In a non-limiting embodiment of the present invention, operators can first install pairs of third steel structures 130 within the container 200 or on the container floor, depending on the number of electrical cabinets and capacitor banks. The spacing between the paired third steel structures 130 should not exceed the longitudinal width of the electrical cabinets and capacitor banks. Furthermore, a positioning steel structure 141 is installed at the leftmost end of the paired third steel structures 130 and fixedly connected to the third steel structures 130 using positioning fasteners 142.

[0056] Attach Figure 1 Taking the first electrical cabinet 310 shown as an example, an operator can use a forklift to move the first electrical cabinet 310 from right to left along the longitudinal direction X onto the third steel structures 130 laid in pairs within the container 200 or on the container-type floor, so that the recess of the second steel structure 113 in the first mounting assembly of the capacitor mounting assembly 100 located at the bottom of the cabinet 310 engages with the outer surface of the leg of the third steel structure 130 transverse to the height edge 1301 of the third steel structure 130, forming a relatively removable connection that is movable along the longitudinal direction X. By pushing the first electrical cabinet 310 from right to left with the aid of an external force, the rollers 122 roll on the outer surface of the leg of the third steel structure 130, so that the bottom of the leftmost end of the first electrical cabinet 310 abuts the positioning steel structure 141, and the axial centers of the first fastening holes 151 and their corresponding second fastening holes 152 coincide with each other. The operator can then use fasteners to secure the cabinet body to the third steel structure 130 via the first fastening holes 151 of the second steel structure 113 and the corresponding second fastening holes 152 of the third steel structure 130. Finally, by further installing a positioning steel structure 141 at the rightmost end of the paired third steel structures 130 and using positioning fasteners 142 to securely connect the positioning steel structure 141 to the third steel structure 130, the position of the first electrical cabinet 310 within the container 200 or on the container-type floor can be defined, preventing relative movement of the first electrical cabinet 310 relative to the container body or container-type floor during transportation.

[0057] Given this sequence, operators can also sequentially lay multiple third steel structures 130 along the longitudinal direction X within a large container, and sequentially install and position each capacitor bank in the same manner. Thus, an integrated containerized high-voltage capacitor assembly is constructed on this installation assembly, which facilitates overall transportation and use.

[0058] In summary, the present invention provides a mounting assembly for containerized high-voltage capacitor assemblies. This assembly overcomes the significant material and cost consumption associated with the use of additional transport plates during the transport and installation of prior art capacitor assemblies, as well as the drawbacks of secondary positioning, inconvenient floor-mounted installation, and the resulting overall loss of the capacitor bank due to positioning and tightening. Furthermore, the present invention utilizes a simple and feasible steel structure to provide a stable positioning and securing structure for electrical cabinets and / or capacitor banks, making it suitable for the installation, securing, and transport of heavy-duty containerized, heavy-duty outdoor power equipment, as well as the use of the containerized high-voltage capacitor assemblies after direct connection to an outdoor power grid.
