[0001] This application relates to the field of vibration testing technology for disconnecting switches, and in particular to a vibration testing device for disconnecting switches. Background Technology

[0002] A control combiner cabinet is a power device used to manage and control multiple power sources or battery packs. It is commonly found in solar photovoltaic systems, wind power generation systems, uninterruptible power supply (UPS) systems, and other applications requiring multi-power source management. Its main function is to aggregate the outputs of multiple power sources and manage and control them uniformly to ensure stable system operation and efficient energy utilization.

[0003] The disconnector switch and its busbar in the control combiner cabinet serve as a bridge connecting the battery pack side and the external PCS side, requiring a series of tests and vibration verifications. To accurately represent the actual installation and operation of the disconnector switch and its busbar in the control combiner cabinet, a fixture is needed to install the disconnector switch. During vibration testing, this fixture must be mounted on a vibration test bench and vibrate along with the disconnector switch to ensure safety and reliability during power-on testing and to obtain accurate vibration test data. However, existing disconnector vibration testing fixtures typically only accommodate one model of disconnector switch, resulting in low reusability and compatibility, and high cost. Summary of the Invention

[0042] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] There are two installation methods for disconnecting switches in control combiner cabinets: vertical installation and horizontal installation. However, existing vibration testing fixtures for disconnecting switches can mostly only be adapted to one type of installation, resulting in low reusability and compatibility, and high cost. The technical concept of this application is that the frame of the disconnecting switch vibration testing device can be connected to a first support plate or a second support plate. The first support plate can be connected to a horizontally installed disconnecting switch, and the second support plate can be connected to a vertically installed disconnecting switch.

[0045] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0046] Example 1

[0047] This embodiment provides a vibration testing device for disconnecting switches, used for installing disconnecting switches. Figure 1 This is a schematic diagram of the vibration testing device for the disconnector switch with the first support plate installed according to an embodiment of this application. Figure 1 ,like Figure 1 As shown, the device includes a frame 100, which comprises a bottom frame 110, a top frame 120, and multiple support columns 130. The bottom frame 110 is located below the top frame 120, and the bottom frame 110 and the top frame 120 are connected by the multiple support columns 130. The bottom frame 110, top frame 120, and support columns 130 can be made of 40mm × 40mm rectangular tubing, serving as the main load-bearing components of the device. The top frame 120 and bottom frame 110 can be rectangular frames formed by connecting four rectangular tubing, and the top frame 120 and bottom frame 110 can be connected by four rectangular tubing serving as support columns 130.

[0048] like Figure 1 As shown, the device is equipped with diagonal braces 140 at the corners of the top frame 120 and bottom frame 110, and at the corners between the top frame 120 or bottom frame 110 and the support column 130. The frame 100 also includes a reinforcing beam 150, which is positioned between the bottom frame 110, top frame 120, and support column 130. Figure 1 As shown, the frame 100 of the device has cross-shaped reinforcing beams 150 on its side. A horizontal reinforcing beam 150 is also provided between the vertical reinforcing beam 150 and the support column 130. The top frame 120 and the bottom frame 110 are both equipped with cross-shaped reinforcing beams 150 inside. The diagonal brace 140 and the reinforcing beam 150 can be made of 30mm×30mm rectangular tubing.

[0049] Considering that the frame 100 vibrates together with the disconnect switch installed inside the device during vibration testing, the purpose of setting up the diagonal brace 140 and the reinforcing beam 150 is to further improve the structural strength of the frame 100 on the basis of the bottom frame 110, the top frame 120 and the support column 130, so that the frame 100 has good vibration resistance.

[0050] like Figure 1 As shown, a first support plate 200 is connected to the frame 100. The first support plate 200 is horizontally positioned inside the frame 100, allowing a horizontally installed disconnecting switch to be connected to it. The first support plate 200 can be used as follows: Figure 1 The reinforcing beams 150 shown are horizontally arranged on both sides of the frame 100, or are directly connected to the support columns 130.

[0051] Figure 2 This is a schematic diagram of the vibration testing device for a disconnector switch with a second support plate installed, provided in an embodiment of this application. Figure 1 ,like Figure 2 As shown, a second support plate 300 is connected to the frame 100. The second support plate 300 is vertically installed inside the frame 100, allowing a vertically installed disconnecting switch to be connected to it. The second support plate 300 can be used as follows: Figure 2 The reinforcing beams 150 shown are vertically arranged on both sides of the frame 100, or are directly connected to the support columns 130.

[0052] like Figure 1 , Figure 2As shown, the frame 100 also includes an adapter plate 160, which is connected to the lower end of the support column 130. The adapter plate 160 is configured to connect to a vibration test platform. The adapter plate 160 can be a rectangular plate or a circular plate, and the number of adapter plates 160 is not limited to four; for example, there can be eight. During vibration testing, the adapter plate 160 is connected to the vibration test platform. An isolating switch is installed inside the frame 100, and the vibration test platform drives the isolating switch and the frame 100 to vibrate together. The adapter plate 160 can be connected to the vibration test platform by multiple screws, such as 24 M12 screws.

[0053] It should be noted that, Figure 1 , Figure 2 This is only used as an example to illustrate the frame 100 in this embodiment. Figure 1 , Figure 2 The specific structure of the frame 100 is not limited. For example, the top frame 120 and the bottom frame 110 can be triangular frames, and the reinforcing beams 150 on both sides of the frame 100 can be two horizontally arranged reinforcing beams 150. The mounting plates, namely the first mounting plate 200 and the second mounting plate 300, need to be connected to the frame 100 in a detachable manner, so that different mounting plates can be replaced according to different disconnector switch models. Figure 1 , Figure 2 The specific connection method between the mounting tray and the frame 100 is not limited. For example, the mounting tray can be connected to the frame 100 by bolts to make the mounting tray detachable, or a clamp can be set on the frame 100 to hold the mounting tray. The clamp can be driven to move by rotating a screw to hold or release the mounting tray.

[0054] The technical effect of this embodiment is:

[0055] The device frame 100 can be connected to a vibration test bench for vibration testing. Since the two types of trays can be connected to horizontally and vertically installed disconnect switches respectively, it can be adapted to disconnect switches with different installation methods, offering high reusability and compatibility, and lower testing costs.

[0056] Example 2

[0057] Figure 3 This is a schematic diagram of the frame provided in the embodiments of this application, such as... Figure 3 As shown, the frame 100 includes a plurality of cable tie frames 170, which are connected to one of the bottom frame 110 and the support column 130. The cable tie frames 170 are used to install electrical wires.

[0058] Figure 3The frame 100 shown includes three cable tie brackets 170. The bottom cable tie bracket 170, located at the bottom frame 110, is fixed to the bottom frame 110 by welding. The rear cable tie bracket 170, located at the rear of the frame 100, is configured to be adjustable in height on the support column 130. Optionally, such as... Figure 3 As shown, multiple through holes can be provided on the two support columns 130 at the rear of the frame 100 along the height direction of the support columns 130. The rear cable tie 170 can be fixed to the rear support column 130 by passing M8 screws through the through holes at the end of the rear cable tie 170 and the through holes on the rear support column 130. Since the two support columns 130 at the rear of the frame 100 have multiple through holes for screws to pass through along the height direction, the height position of the rear cable tie 170 on the rear support column 130 can be adjusted by connecting to different through holes. In this embodiment, each of the two rear support columns 130 can be provided with 6 through holes with a diameter of 9mm, and the through holes of the two rear support columns 130 are symmetrically arranged.

[0059] The rear support column 130 of the frame 100 can also be provided with a guide rail along the height direction. The guide rail is slidably connected to the slider, and the slider is connected to the rear cable tie 170. Thus, the height position of the rear cable tie 170 on the rear support column 130 can be adjusted by sliding. The guide rail and the slider can be locked in place by a locking mechanism to prevent the rear cable tie 170 from slipping off.

[0060] Since the electrical components of the disconnecting switch need to be installed on the cable tie 170, the purpose of making the height of the rear cable tie 170 adjustable is to accommodate different wiring methods during the power-on testing of the disconnecting switch.

[0061] like Figure 3 As shown, the frame 100 also includes a forklift bay 180, which is located at the lower end of the bottom frame 110. Figure 3 In the middle, four forklift bay openings 180 are connected to the bottom frame 110, symmetrically arranged on both sides of the bottom frame 110. During transportation, each forklift fork can pass through two of the symmetrically arranged forklift bay openings 180, thus ensuring relative stability when transporting the frame 100. The size of the forklift bay opening 180 should be adapted to the size of the forks; for example, the size of the forklift bay opening 180 can be 200mm × 800mm, and the hole spacing can be 280mm.

[0062] like Figure 3 As shown, multiple binding holes 400 may be provided on some of the reinforcing beams 150. Figure 3In the frame 100, the vertically arranged reinforcing beams 150 on both sides, the top frame 120, and part of the reinforcing beams 150 of the bottom frame 110 are provided with wire binding holes 400. By providing wire binding holes 400, cable ties can be installed for wire binding during the power-on test of the disconnect switch. In this embodiment, the diameter of the wire binding hole 400 can be 5mm.

[0063] Figure 4 This is a schematic diagram of the vibration testing device for the disconnector switch with the first support plate installed according to an embodiment of this application. Figure 2 ,like Figure 4 As shown, the first pallet 200 is connected to the horizontally arranged reinforcing beams 150 on both sides of the frame 100 via the first connector 500.

[0064] Figure 5 Schematic diagram of a vibration testing device for a disconnector switch with a second mounting plate provided in an embodiment of this application. Figure 2 ,like Figure 5 As shown, the second support plate 300 is connected to the vertically arranged reinforcing beams 150 on both sides of the frame 100. The second support plate 300 can be connected to the vertical reinforcing beams 150 through the first connector 500.

[0065] In this embodiment, the first connector 500 is an M10 bolt, such as... Figure 4 As shown, two bolt holes are provided on each of the horizontal reinforcing beams 150 on both sides of the frame 100, and the first support plate 200 is connected to the horizontal reinforcing beam 150 by M10 bolts. Figure 5 As shown, two bolt holes are provided on each of the vertical reinforcing beams 150 on both sides of the frame 100, and the second support plate 300 is connected to the vertical reinforcing beam 150 by M10 bolts.

[0066] like Figure 5 As shown, when the second support plate 300 is vertically installed inside the frame 100, two horizontal reinforcing beams 150 are provided on each side of the frame 100. On each side of the frame 100, the two horizontal reinforcing beams 150 support the second support plate 300, thereby improving the stability of the second support plate 300 during vibration testing.

[0067] like Figure 4 , Figure 5 As shown, both the first tray 200 and the second tray 300 are provided with a plurality of second connectors 600 for connecting disconnect switches.

[0068] In this embodiment, the second connector 600 has a bottom hole and can be connected to the disconnecting switch by welding a nut. By setting holes at different positions on the first support plate 200 and the second support plate 300, a single mounting plate can be adapted to different models of disconnecting switches.

[0069] Figure 6 A side view of the mounting tray provided in an embodiment of this application, such as Figure 6 As shown, the first tray 200 and the second tray 300 have bent portions at both ends. Multiple reinforcing ribs can be provided at the bottom of the first tray 200 and the second tray 300. By providing bent portions and bottom reinforcing ribs, the structural strength of the first tray 200 and the second tray 300 can be improved, and the wires can be prevented from being cut.

[0070] The bottom of the first support plate 200 is provided with a support frame 210, which is symmetrically arranged. Since the busbar of the disconnect switch is very heavy, the support frame 210 can support the busbar, making the overall structure more stable.
