Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and more specifically to a switch cabinet structure. Background Technology

[0002] Currently, the cabinet structure of existing switchgear is still consistent with the old-fashioned traditional cabinets. The traditional cabinet layout has a lot of space redundancy. Firstly, this is because the older electronic components are technologically inferior, resulting in larger components and poorer insulation, thus requiring additional space inside the switchgear for safety clearance. Secondly, part of the reason is to accommodate the uncertainties of early power grid upgrades, reserving space for backup and expansion.

[0003] However, with the technological improvement of electronic components, the electronic components inside the cabinet can be made smaller and have better insulation. The power grid system is also standardized and modularized, and various functions are perfected, reducing the uncertainty of adapting to power grid transformation. Therefore, the cabinet of the switch cabinet gradually no longer needs so much space redundancy. At the same time, the demand for cabinet miniaturization is gradually increasing. If the old cabinet structure is still used, it will not only waste space, but also make it difficult to meet the miniaturization requirements. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a cabinet structure for a switch cabinet. By rationally adjusting the internal space layout of the cabinet, the cabinet becomes more compact and smaller, and has a wider range of applications.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a switch cabinet structure, comprising a cabinet body, the cabinet body including a main busbar compartment, the main busbar compartment being provided with a plurality of busbars arranged in an inverted L-shape, and branch lines extending from the concave corners of the inverted L-shaped busbars, the branch lines being arranged vertically.

[0006] The present invention is further configured such that: the cabinet includes a handcart compartment, and a contact device is provided below the branch row and at the inner end of the handcart compartment, the contact device being used to connect with the handcart inside the handcart compartment.

[0007] The present invention is further configured such that the contact device comprises an integrated contact box and a current transformer.

[0008] The present invention is further configured such that: a grounding knife device is provided at the lower part of the cabinet, and the grounding knife device is located on the front side of the cabinet near the cabinet door along the center line of the cabinet.

[0009] The present invention is further configured such that: the lower part of the cabinet is provided with a cable chamber, which is located on the rear side of the center line of the cabinet away from the cabinet door.

[0010] The present invention is further configured such that: a small busbar terminal is provided inside the cabinet, and the small busbar terminal is located in the cavity of the cabinet located in front of the main busbar compartment.

[0011] The present invention is further configured such that a metal partition is provided on the periphery of the main busbar chamber.

[0012] The present invention is further configured such that the edges of the busbar are chamfered.

[0013] In summary, this utility model has the following beneficial effects:

[0014] This invention adjusts the layout of the main busbar indoor busbars to an inverted L-shape, making the main busbar compartment smaller and more compact than traditional designs. Simultaneously, branch lines extend from the concave corners of the L-shape, ensuring a safe distance between the branch lines and each busbar while maintaining a small footprint, thus guaranteeing safety. Furthermore, the vertical arrangement of the branch line seats effectively reduces the size of the switchgear, especially in the width direction, resulting in a smaller cabinet structure that better adapts to different sizes of external spaces, broadening its applicability.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This embodiment discloses a cabinet structure for a switchgear, such as... Figure 1-2As shown, the device includes a cabinet 1, which includes a main busbar compartment 2. The main busbar compartment 2 contains several busbars 3 arranged in an inverted L-shape. Traditional busbars are mostly arranged linearly, such as horizontally or vertically, but this method occupies more space. Therefore, this invention uses an inverted L-shape layout, which makes more reasonable use of the space in the main busbar compartment and can effectively reduce the cabinet depth. At the same time, branch lines 4 are extended from the concave corners of the inverted L-shaped busbars 3. The branch lines 4 are positioned at this location to maintain a safe distance from the three busbars 3, which is reasonable. Furthermore, the branch lines 4 are arranged vertically. When designed vertically, the adjacent conductors are staggered vertically, and the electric field lines are distributed longitudinally, which will not cause the electric field to superimpose, thus achieving a smaller safe distance. Similarly, to further optimize space utilization, the main busbar compartment 2 is equipped with metal partitions around its perimeter. Because this reduces the overall cabinet depth, aluminum partitions can be installed around the main busbar compartment 2, or aluminum partitions can be inserted between the phases of the busbars for protection. Furthermore, the edges of the busbar copper busbars can be chamfered to prevent point discharge and ensure safety. Through this structure, the space of the main busbar compartment is effectively compressed, avoiding wasted space and reducing the cabinet depth, making it suitable for miniaturization requirements.

[0020] Furthermore, the cabinet 1 includes a handcart compartment 5, and a contact device 6 is provided below the branch row 4 and located at the inner end of the handcart compartment 5. The contact device 6 is used to connect with the handcart inside the handcart compartment 5. Due to the compression of the overall cabinet depth, placing the contact device 6 below the branch row 4 can ensure a safe distance. At the same time, the contact device 6 adopts an integrated contact box and current transformer, and its specific structure is the same as that in the prior art, such as the contact box type current transformer disclosed in CN206003620U. The advantage of the integrated design is that it is smaller in size and more suitable for the miniaturization purpose of this utility model.

[0021] Furthermore, to coordinate with the reduction in cabinet depth, a grounding device 8 is provided at the lower part of the cabinet 1. The grounding device 8 is located on the front side of the cabinet 1 near the cabinet door along the centerline. A cable compartment 7 is also provided at the lower part of the cabinet 1. The cable compartment 7 is located on the rear side of the cabinet 1 away from the cabinet door along the centerline. In traditional switchgear, the grounding device 8 is generally located at the rear of the lower part of the cabinet. However, when the cabinet depth is reduced, this utility model readjusts the layout of the grounding device 8 to release and expand the space of the cable compartment 7. While reducing the cabinet depth, it does not affect the convenience of cable installation and maintenance. At the same time, the larger cable compartment space is conducive to the dissipation of cable heat.

[0022] Furthermore, as a preferred embodiment, a small busbar terminal 9 is provided inside the cabinet 1, located in the chamber of the cabinet 1 on the front side of the main busbar compartment 2. Traditionally, the small busbar terminal 9 is located outside the cabinet for secondary wiring. With the standardization of power grid systems, secondary wiring is an essential component. Therefore, moving the small busbar terminal 9 inside the cabinet allows secondary wiring operations to be performed inside a more protected and organized space, making wiring easier for operators and reducing the difficulty and time required. Simultaneously, being located inside provides better dustproof, moisture-proof, and impact-resistant capabilities than being outside the cabinet, reducing the risk of terminals being exposed to the external environment. Furthermore, integrating the small busbar terminal 9 internally also makes the wiring simpler and more aesthetically pleasing.

[0023] In summary, by adjusting the layout of the overall cabinet structure, this utility model significantly reduces the size of the cabinet, making better use of the internal space. It can achieve a size of 550×1100×2000 mm (width, height, and depth), which greatly meets the need for miniaturization of the cabinet and significantly reduces the space requirements of the area.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
