Description

Technical Field

[0001] This utility model relates to the technical field of saturated reactors, and in particular to a lower support device for a saturated reactor. Background Technology

[0002] Currently, saturated reactors, as important reactive power compensation devices in power systems, mainly consist of a reactor core assembly and copper busbars passing through the core assembly. They are widely used in rectifier transformers, electrolysis, chemical industries, and other sectors. In existing saturated reactors, the lower part of the copper busbar is typically supported by a single layer of crossbeams. The weight of the copper busbar is concentrated in a localized area of ​​this single layer, leading to uneven stress distribution and stress concentration. Furthermore, because saturated reactors are prone to vibration during transportation and operation, the lower part of the copper busbar is constantly subjected to external forces on the single layer of crossbeams. After prolonged operation, the single layer of crossbeams is prone to deformation, thus affecting the supporting effect of the copper busbar. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a lower support device for a saturated reactor. The copper busbar is supported by a first horizontal beam, and the first horizontal beam is supported by a second horizontal beam to form a nested support structure. This avoids the problem of force concentration at a single support point, thereby improving the overall stability of the copper busbar support.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A lower support device for a saturated reactor includes: a fixed frame, a first horizontal beam arranged along the height direction of the fixed frame, a plurality of first slots arranged at the upper end of the first horizontal beam, the first slots being used to install the copper busbars of the reactor, a second horizontal beam arranged below the first horizontal beam of the fixed frame, a second slot arranged at the upper end of the second horizontal beam, the lower part of the first horizontal beam cooperating with the second slot, and the first horizontal beam and the second horizontal beam being arranged perpendicularly and alternately.

[0005] Furthermore, the fixing frame includes two opposing first base plates, each first base plate having a plurality of insert rods spaced apart along its length, and the two ends of the second crossbeam having downward-facing insertion holes, with two insert rods located on the same straight line opposite each other being inserted into the insertion holes of the second crossbeam.

[0006] Furthermore, each of the first base plates is vertically connected to a side plate, and the two ends of the second crossbeam abut between the two side plates.

[0007] Furthermore, the fixing frame also includes two second base plates connected between the two first base plates. Each first base plate has multiple L-shaped plates on its upper surface, and the first crossbeam is installed between the two L-shaped plates located on the same straight line.

[0008] Furthermore, the L-shaped plate includes a horizontal plate and a vertical plate that are perpendicularly connected to each other. The lower end of the vertical plate is connected to the second base plate. The horizontal plate has mounting holes, and the first horizontal beam is connected to the mounting holes by bolts.

[0009] Furthermore, the first base plate and the second base plate are vertically welded together as one piece, and the two first base plates and the two second base plates together form a rectangular frame.

[0010] Furthermore, the fixing frame also includes four support plates, each of which is located at a corner of the rectangular frame, and the upper end of the four support plates is provided with a mounting frame for mounting the reactor.

[0011] Furthermore, it also includes four lifting lugs, which are rectangularly distributed around the outer periphery of the mounting frame.

[0012] Compared with existing technologies, this utility model has at least the following beneficial effects: In this invention, the external force generated by the gravity or vibration of the copper busbar is transmitted to the second crossbeam through the first crossbeam, and then to the fixed frame through the second crossbeam. Thus, the nested support of the first and second crossbeams forms a multi-level force transmission path, avoiding the deformation risk caused by excessive local stress in the previous single-layer crossbeam. This helps to improve the overall stability of the copper busbar support and effectively resist the vibration impact during equipment operation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] See Figures 1 to 3 A lower support device for a saturated reactor includes: a fixing frame 100, a first crossbeam 110 arranged along the height direction of the fixing frame 100, a plurality of first slots arranged at the upper end of the first crossbeam 110, the first slots being used to install the copper busbar 210 of the reactor 200, a second crossbeam 120 arranged below the first crossbeam 110 of the fixing frame 100, a second slot arranged at the upper end of the second crossbeam 120, the lower part of the first crossbeam 110 cooperating with the second slot, and the first crossbeam 110 and the second crossbeam 120 being arranged perpendicularly and alternately.

[0020] In the lower support device of the saturated reactor with the above structure, the external force generated by the gravity or vibration of the copper busbar 210 is transmitted through the first crossbeam 110 to the second crossbeam 120, and then from the second crossbeam 120 to the fixed frame 100. Thus, the nested support of the first crossbeam 110 and the second crossbeam 120 forms a multi-level force transmission path, avoiding the deformation risk caused by excessive local stress in the previous single-layer crossbeam. This helps to improve the overall stability of the copper busbar 210 support and effectively resist the vibration impact during equipment operation.

[0021] See Figures 1 to 3 Furthermore, the fixing frame 100 includes two opposing first base plates 101. Each first base plate 101 has multiple insert rods 102 spaced apart along its length. The second crossbeam 120 has downward-facing insertion holes at both ends. Two insert rods 102 located on the same straight line and facing each other are inserted into the insertion holes of the second crossbeam 120. Specifically, by utilizing the downward-facing insertion holes at both ends of the second crossbeam 120 and the corresponding insertion of the insert rods 102, the second crossbeam 120 can be quickly positioned and fixed between the two first base plates 101. The interlocking structure of the insert rods 102 and the insertion holes restricts the horizontal displacement of the second crossbeam 120, thus facilitating the subsequent installation of the first crossbeam 110 onto the second crossbeam 120. It is understood that the insert rods 102 can be fixed to the first base plate by welding, and the spaced arrangement of multiple insert rods 102 allows for adjustment of the installation position of the second crossbeam 120 according to actual needs, providing high flexibility.

[0022] See Figures 1 to 3 Furthermore, each first base plate 101 is vertically connected to a side plate 103, and the two ends of the second crossbeam 120 abut against the two side plates 103, thereby using the two side plates 103 to further restrict the lateral displacement of the second crossbeam 120 in the horizontal direction, which is beneficial to the stability of the installation of the second crossbeam 120.

[0023] See Figures 1 to 3Furthermore, the fixing frame 100 also includes two second base plates 104 connected between two first base plates 101. Each first base plate 101 has multiple L-shaped plates 105 on its upper surface, and a first crossbeam 110 is installed between two L-shaped plates 105 located on the same straight line. Specifically, placing the first crossbeam 110 between two L-shaped plates 105 allows the L-shaped plates 105 to not only raise the first crossbeam 110 but also facilitates the positioning and fixing of both ends of the first crossbeam 110, thus ensuring a reliable connection between the first crossbeam 110 and the fixing frame 100. It is understood that there are two second horizontal beams 120, with a second slot penetrating the upper part of the second horizontal beam 120. The second horizontal beam 120 is installed longitudinally between two corresponding insert rods 102. There are two first horizontal beams 110, each of which is installed laterally between two corresponding L-shaped plates 105, so that the first horizontal beam 110 is inserted downward into the second slot, thereby using the second horizontal beam 120 to support the first horizontal beam 110 upward. In some embodiments, each second horizontal beam 120 is located between two first slots, thereby using multiple second horizontal beams 120 to further evenly distribute the force on the first horizontal beam 110. The overall structure is simple and the installation is quick and convenient.

[0024] See Figures 1 to 3 Furthermore, the L-shaped plate 105 includes horizontal and vertical plates connected perpendicularly to each other. The lower end of the vertical plate is connected to the second base plate 104. The horizontal plates have mounting holes 106, and the first horizontal beam 110 is bolted to the mounting holes 106. Specifically, after the first horizontal beam 110 is placed between the two horizontal plates, the bolts are passed through the mounting holes 106 of the horizontal plates and screwed into the pre-drilled threaded holes of the first horizontal beam 110. Then, the bolts are tightened to secure the first horizontal beam 110 tightly above the horizontal plates. This facilitates easier installation and removal of the first horizontal beam 110, and also makes later maintenance and replacement easier. It is understood that the horizontal and vertical plates of the L-shaped plate 105 are connected by integral molding or welding.

[0025] See Figures 1 to 3 Furthermore, the first base plate 101 and the second base plate 104 are vertically welded together, and the two first base plates 101 and the two second base plates 104 together form a rectangular frame. Specifically, the rectangular frame has a regular shape and a stable geometric structure, which facilitates the improvement of the strength and stability of the bottom structure of the fixing frame 100, thereby facilitating the installation of other components.

[0026] See Figures 1 to 3Furthermore, the mounting bracket 100 also includes four support plates 107, each support plate 107 being located at a corner of the rectangular frame. A mounting frame 108 is provided at the upper end of the four support plates 107, and the mounting frame 108 is used to mount the reactor 200. Specifically, the support plates 107 are located at the corners of the rectangular frame, utilizing the high strength characteristics of the corners to stably support the upper mounting frame 108. The mounting frame 108 serves as the mounting carrier for the reactor 200, connecting to the bottom rectangular frame via the support plates 107, thus transferring the weight of the reactor 200 to the rectangular frame, which is beneficial for stabilizing the installation and support of the reactor 200. In some embodiments, the reactor 200 includes an iron core assembly and a copper busbar 210 passing through the iron core assembly. The iron core assembly is clamped by an upper epoxy cloth plate and a lower epoxy cloth plate. The lower epoxy cloth plate is installed inside the mounting frame 108 and fixed to the mounting frame by bolts, thereby completing the step of fixing the iron core assembly to the mounting frame 100.

[0027] See Figure 1 and Figure 2 Furthermore, it also includes four lifting lugs 109, which are rectangularly distributed around the outer perimeter of the mounting frame 108. Specifically, when it is necessary to lift and move the fixed frame 100 and the reactor 200 installed on it, the lifting force is evenly distributed on the four lifting lugs 109 through the connection between the lifting equipment and the lifting lugs 109, and then transmitted to the mounting frame 108 to achieve a smooth and safe lifting operation.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
