[0001] This invention belongs to the field of switchgear technology, specifically relating to a switchgear group that can be arranged in parallel and its usage method. Background Technology

[0002] A switchgear is an electrical device that mainly consists of circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protection devices. It functions to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes of a power system. It is suitable for various occasions such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings.

[0003] In practical use, multiple switchgear units often need to be arranged together for combined use. However, in the existing technology, there is no easy connection structure between adjacent switchgear units, which makes the switchgear units susceptible to movement due to external forces and has poor stability. Switchgear units that can be combined and fixed are not easy to disassemble and separate after being fixed, which is not conducive to the recombination of switchgear units. Therefore, we propose a switchgear unit that can be set up in parallel. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a switch cabinet group that can be arranged in parallel and a method of use, so that several switch cabinet groups can be fixed in parallel and are also easy to disassemble and recombine.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a switch cabinet group that can be arranged in parallel, including several switch cabinet groups, a fixing plate is provided on the upper side of the switch cabinet group, a locking plate is provided at one end of the fixing plate, a connecting plate is provided at the other end of the fixing plate, and a connecting component is provided in the connecting plate to connect with the locking plate on another switch cabinet group. One group of switchgear is connected to another group of switchgear via a connecting plate and internal connecting components. Several groups of switchgear are arranged side by side in sequence.

[0006] As a preferred embodiment of the present invention, the connecting assembly includes a groove, a guide rod, a slider, a rotating rod, and a connecting rod. The groove is symmetrically opened on both sides of the connecting plate. The guide rod is disposed inside the groove and connected to the inner wall of the groove. The slider is sleeved on the guide rod. The rotating rod is disposed on one side of the slider. One end of the connecting rod is connected to the rotating rod and rotates synchronously with the rotating rod.

[0007] As a preferred embodiment of the present invention, the connecting assembly further includes a limiting spring, which is sleeved on one end of the guide rod.

[0008] As a preferred embodiment of the present invention, one end of the limiting spring is welded to one side of the slider, and the other end of the limiting spring is welded to the inner wall of the groove.

[0009] As a preferred embodiment of the present invention, a limiting groove adapted to the connecting rod is provided on one side of the locking plate, and the connecting rod is locked in the limiting groove.

[0010] As a preferred embodiment of the present invention, a pull plate is provided on one side of the connecting rod for the operator to pull, and the side of the pull plate is rounded.

[0011] As a preferred embodiment of the present invention, the surface of the pull plate is provided with a second limiting groove, which is symmetrically arranged on both sides of the pull plate.

[0012] As a preferred embodiment of the present invention, the slider has a through hole that fits with the guide rod, and the inner wall of the through hole abuts against the outer wall of the slider.

[0013] As a preferred embodiment of the present invention, the switch cabinet assembly and the fixing plate are provided with several sets of screw holes for bolt connection on one side, and the switch cabinet assembly and the fixing plate are connected by bolts and screw holes.

[0014] The present invention also provides a technical solution, a method for using a switchgear group that can be arranged in parallel, the specific steps of which are as follows: A. Prepare several sets of switchgear; B. Adjust the position of the switchgear groups so that several switchgear groups are arranged side by side in sequence; C. Several groups of switchgear cabinets arranged in a fixed parallel configuration; C1. Prepare several sets of fixing plates; C2. Place the fixing plate on the upper side of the switch cabinet assembly, adjust the position of the fixing plate, and fix the fixing plate to the switch cabinet assembly with bolts; C3. Adjust the connecting component inside the connecting plate on one set of fixing plates, and connect and fix the connecting plate to the locking plate on the other set of fixing plates through the connecting component; C4. Flip the connecting rod in one of the connecting components and rotate the connecting rod through the rotating rod on the side of the slider towards the locking plate on the other set of fixing plates, so that the connecting rod is close to the locking plate on the other set of fixing plates. C5. Pull the connecting rod through the limiting groove in the pull plate. The connecting rod drives the slider through the rotating rod. Under the guidance of the guide rod, it squeezes the limiting spring. The limiting spring deforms under force, causing the connecting rod to move away from the locking plate. C6. Repeat steps C4 until the connecting rod is rotated 180° and facing the side of the locking plate. C7. Then release the pull on the connecting rod. Using the return action of the limit spring, the limit spring pushes the slider, and the slider drives the connecting rod connected to the rotating rod to move closer to the locking plate until the connecting rod moves into the limit groove one in the locking plate. C8. Complete the connecting plate on one set of fixing plates and connect and fix it to the snap-fit ​​plate on the other set of fixing plates; C9. Repeat steps C3-C8 sequentially for the fixing plates on several sets of switchgear. D. Complete the parallel fixing of several sets of switchgear; E. Disassemble the parallel and fixed switchgear assembly; E1. Pull the connecting rod through the second limiting groove in the pull plate away from the locking plate. The connecting rod drives the slider through the rotating rod. Under the guidance of the guide rod, the limiting spring is squeezed. The limiting spring is deformed by the force, causing the connecting rod to move out of the first limiting groove in the locking plate. E2. Then rotate the connecting rod 180° in the opposite direction, turning the connecting rod from one side of the connecting plate to the other side; E3. Release the pull on the connecting rod, and use the restoring property of the limit spring to push the slider, which in turn drives the connecting rod connected to the rotating rod to return to its original position. E4. For the switch cabinet groups that need to be disassembled, repeat the steps of E1-E3. F. Complete the disassembly of the parallel fixed switchgear group.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. In this invention, a group of switch cabinets is connected to a locking plate on another group of switch cabinets through a connecting plate and internal connecting components. Several groups of switch cabinets are arranged side by side in sequence.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: like Figure 1-5 As shown in the figure, this embodiment proposes a switch cabinet group that can be arranged in parallel, including several switch cabinet groups 1. A fixing plate 2 is provided on the upper side of the switch cabinet group 1. A locking plate 3 is provided at one end of the fixing plate 2, and a connecting plate 4 is provided at the other end of the fixing plate 2. A connecting component 5 is provided inside the connecting plate 4 to connect with the locking plate 3 on another switch cabinet group 1. One switch cabinet group 1 is connected to the locking plate 3 on another switch cabinet group 1 through the connecting plate 4 and the internal connecting component 5. Several switch cabinet groups 1 are arranged in parallel in sequence. Conversely, by adjusting the connecting component 5, the connection plate 4 and the locking plate 3 can be disassembled, so that several switch cabinet groups 1 can be fixed in parallel and can also be easily disassembled and recombined.

[0022] The connecting assembly 5 includes a groove 51, a guide rod 52, a slider 53, a rotating rod 54, and a connecting rod 55. The groove 51 is symmetrically opened on both sides of the connecting plate 4. The guide rod 52 is disposed inside the groove 51 and connected to the inner wall of the groove 51. The slider 53 is sleeved on the guide rod 52. The rotating rod 54 is disposed on one side of the slider 53. One end of the connecting rod 55 is connected to the rotating rod 54 and rotates synchronously with the rotating rod 54. The connecting assembly 5 also includes a limiting spring 56, which is sleeved on one end of the guide rod 52. When fixed, flip the connecting rod 55 in one of the connecting components 5, and rotate the connecting rod 55 towards the locking plate 3 on the other set of fixing plates 2 via the rotating rod 54 on one side of the slider 53. This brings the connecting rod 55 closer to the locking plate 3 on the other set of fixing plates 2. Then pull the connecting rod 55, which drives the slider 53 via the rotating rod 54. Under the guidance of the guide rod 52, the connecting rod 55 compresses the limiting spring 56. The limiting spring 56 deforms under the force, causing the connecting rod 55 to move away from the locking plate 3. Move in the direction and continue to rotate the connecting rod 55 until the connecting rod 55 is rotated 180° to face the side of the locking plate 3. Release the pull on the connecting rod 55, and use the return shape of the limit spring 56 to push the slider 53. The slider 53 drives the connecting rod 55 connected to the rotating rod 54 to move closer to the locking plate 3 until the connecting rod 55 touches the locking plate 3. This completes the connection and fixation between the connecting plate 4 on one set of fixing plates 2 and the locking plate 3 on another set of fixing plates 2. During disassembly, pull the connecting rod 55 away from the locking plate 3. This causes the connecting rod 55 to drive the slider 53 via the rotating rod 54. Guided by the guide rod 52, the slider 55 is compressed and the limiting spring 56 is deformed. This causes the connecting rod 55 to move away from the locking plate 3. Then, release the pull on the connecting rod 55. Using the restoring property of the limiting spring 56, the limiting spring 56 pushes the slider 53. The slider 53 then drives the connecting rod 55 connected to the rotating rod 54 to return to its original position, thus completing the disassembly.

[0023] One end of the limiting spring 56 is welded to one side of the slider 53, and the other end of the limiting spring 56 is welded to the inner wall of the groove 51. This allows for the limiting and fixing of both ends of the limiting spring 56, which helps improve the stability of the deformation of the limiting spring 56. The slider 53 has a through hole 9 that fits onto the guide rod 52. The inner wall of the through hole 9 abuts against the outer wall of the slider 53, allowing the slider 53 to fit onto the guide rod 52 through the through hole 9. This better limits the slider 53 and further improves the stability of use. Both the switch cabinet assembly 1 and the fixing plate 2 have several sets of screw holes on one side for bolt connection. The switch cabinet assembly 1 and the fixing plate 2 are connected by bolts and the threads of the screw holes. This makes it convenient to remove the fixing plate 2 for maintenance of the connection assembly 5 later.

[0024] One side of the locking plate 3 has a limiting groove 6 that matches the connecting rod 55. The connecting rod 55 is engaged in the limiting groove 6, which can be sleeved on the limiting groove 6 on one side of the locking plate 3 to limit the connecting rod 55 and improve the stability of the connecting rod 55 on one side of the locking plate 3. One side of the connecting rod 55 is provided with a pull plate 7 for the operator to pull, so that the operator can pull the pull plate 7 to drive the connecting rod 55. The side of the pull plate 7 is rounded to improve the comfort of the operator to pull. The surface of the pull plate 7 has a limiting groove 8, which is symmetrically arranged on both sides of the pull plate 7. The limiting groove 8 provides a pulling point for the operator to pull the pull plate 7, making it easier to pull the pull plate 7.

[0025] A method for using a switchgear group that can be arranged in parallel, the specific steps are as follows: A. Prepare several sets of switchgear group 1; B. Adjust the position of switchgear group 1 so that several switchgear groups 1 are arranged side by side in sequence; C. Several groups of switch cabinets arranged in a fixed parallel configuration; C1. Prepare several sets of fixing plates 2; C2. Place the fixing plate 2 on the upper side of the switch cabinet assembly 1, adjust the position of the fixing plate 2, and fix the fixing plate 2 to the switch cabinet assembly 1 with bolts; C3. Adjust the connecting component 5 inside the connecting plate 4 on one set of fixed plates 2, and connect and fix the connecting plate 4 to the snap-fit ​​plate 3 on the other set of fixed plates 2 through the connecting component 5. C4. Flip the connecting rod 55 in one of the connecting components 5, and rotate the connecting rod 55 towards the locking plate 3 on the other set of fixing plates 2 via the rotating rod 54 on one side of the slider 53, so that the connecting rod 55 is close to the locking plate 3 on the other set of fixing plates 2. C5. Pull the connecting rod 55 through the limiting groove 8 in the pull plate 7. The connecting rod 55 drives the slider 53 through the rotating rod 54. Under the guidance of the guide rod 52, it squeezes the limiting spring 56. The limiting spring 56 deforms under the force, causing the connecting rod 55 to move away from the locking plate 3. C6. Repeat steps C4 until the connecting rod 55 is rotated 180° and faces the side of the locking plate 3. C7. Then release the pull on the connecting rod 55. Using the reset shape of the limit spring 56, the limit spring 56 pushes the slider 53. The slider 53 drives the connecting rod 55 connected to the rotating rod 54 to move closer to the locking plate 3 until the connecting rod 55 moves into the limit groove 6 in the locking plate 3. C8. Complete the connection plate 4 on one set of fixing plates 2 and connect and fix it to the snap-fit ​​plate 3 on the other set of fixing plates 2; C9. Repeat steps C3-C8 sequentially for the fixing plates 2 on several sets of switch cabinet groups 1. D. Complete the parallel fixing of several groups of switch cabinets, group 1; E. Disassemble the parallel and fixed switchgear group 1; E1. Pull the connecting rod 55 away from the locking plate 3 by passing it through the limiting groove 2 8 in the pull plate 7. This causes the connecting rod 55 to drive the slider 53 through the rotating rod 54. Under the guidance of the guide rod 52, the slider 53 is squeezed and the limiting spring 56 is deformed by the force, causing the connecting rod 55 to move out of the limiting groove 1 6 in the locking plate 3. E2. Then rotate the connecting rod 55 180° in the opposite direction, and rotate the connecting rod 55 from one side of the connecting plate 4 to the other side. E3. Release the pull on the connecting rod 55, and use the restoring property of the limit spring 56 to push the slider 53. The slider 53 drives the connecting rod 55 connected to the rotating rod 54 to return to its original position. E4. For switch cabinet group 1 among the several groups that need to be disassembled, repeat the steps of E1-E3. F. Complete the disassembly of the parallel fixed switchgear group 1.
