Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to cabinet structure for switch cabinets and switch cabinets having the same. Background Technology

[0002] Switchgear, as a key power distribution device in power systems, is widely used in various settings such as substations, commercial buildings, and residential communities for the distribution, control, and protection of electrical energy. Switchgear may include a cabinet structure with multiple compartments and various electrical components arranged in the corresponding compartments, such as the main busbars arranged in the busbar compartment of the cabinet structure and secondary devices arranged in the secondary compartments of the cabinet structure.

[0003] However, the cabinet structure in the prior art still has at least the following defects: (1) The busbar compartment is usually arranged on the top side of the cabinet structure, which means that when installing the main busbar that extends horizontally, it is necessary to insert the main busbar into the busbar compartment of the cabinet structure one by one from the horizontal side of the cabinet structure. This results in a relatively complicated structure and complex assembly relationship, especially when the main busbar is large in size and the site space is limited; (2) The main busbar is usually connected to the distribution busbar with fasteners such as bolts. However, since the main busbar has different sizes and needs to be connected to the corresponding distribution busbar, it is necessary to open bolt connection holes of different numbers and sizes on the main busbar. This is obviously not conducive to standardization and large-scale operation, and will also lead to poor flexibility and extremely low production efficiency; (3) The secondary compartment of the cabinet structure is usually formed on the frame of the cabinet structure with partitions, and then the required secondary devices are arranged in the secondary compartment. This will also lead to the defect of low production efficiency.

[0004] Therefore, there is a demand in this field for cabinet structures that are easy to assemble and have high production efficiency within switchgear. Utility Model Content

[0005] The present invention aims to provide a cabinet structure for switchgear that can at least solve some of the above-mentioned problems.

[0006] This utility model also aims to provide a switch cabinet that applies the above-mentioned improved cabinet structure.

The system includes an upper support plate and a lower support plate arranged vertically at intervals. The lower support plate has a vertically penetrating connecting hole. The mounting component is configured to extend from below the lower support plate through the connecting hole and be detachably connected to the lower support plate. The upper support plate has an operating opening that surrounds the connecting hole of the lower support plate on a horizontal plane and leads to the connecting hole of the lower support plate vertically, allowing external operating tools to pass through the operating opening of the upper support plate from above the cabinet structure to operate the mounting component to switch between a locked and unlocked state.

[0008] Compared to existing technologies, the cabinet structure of this invention provides removable support beams relative to the rest of the cabinet frame. These support beams can be removed when the main busbar needs to be installed into the busbar compartment on the top side of the cabinet frame, allowing the lateral sides of the top support frame to be opened. This facilitates the operator's insertion of the main busbar into the busbar compartment from top to bottom. Furthermore, the mounting components for connecting the support beams to the frame body are located below the support beams, and the support beams have operating openings that allow tools to engage and control the mounting components from above. This further improves the convenience of installing and removing the support beams.

[0010] Preferably, the mounting component is configured to include two pairs of mounting structures corresponding to the pair of support beams respectively. Each mounting structure includes a mounting member fixedly mounted to the frame body and located below the corresponding support beam, and a fastener extending through a connecting hole in the lower support plate of the mounting member and the corresponding support beam to detachably connect the mounting member and the corresponding support beam together.

[0011] Preferably, the cabinet structure further includes a busbar mounting frame installed in the busbar chamber at the top of the frame body to hold the main busbar of the switch cabinet therein.

[0012] Preferably, the busbar mounting frame includes an upper busbar clamp, a busbar separator, and a lower busbar clamp arranged vertically at intervals. The upper busbar clamp and the lower busbar clamp are fixedly arranged relative to the frame body, and the busbar separator is arranged between the upper busbar clamp and the lower busbar clamp, so that the upper busbar clamp and the busbar separator can clamp a first main busbar portion of the main busbar therein, and the busbar separator and the lower busbar clamp can clamp a second main busbar portion of the main busbar therein, such that the second main busbar portion of the main busbar is arranged at intervals relative to the first main busbar portion.

[0013] Preferably, the busbar separator is movably arranged relative to the frame body to allow adjustment of the spacing between the upper busbar clamp and the busbar separator, as well as the spacing between the busbar separator and the lower busbar clamp.

[0014] Preferably, the cabinet structure further includes a secondary enclosure that is integrally installed inside the main frame body and below the busbar compartment. The secondary enclosure is arranged on the longitudinal front side of the main frame body and its longitudinal front side is provided with an installation opening.

[0015] Preferably, the main frame includes multiple vertically extending columns arranged at intervals relative to each other and multiple connecting beams extending transversely to the multiple columns.

[0016] Preferably, the cabinet structure further includes a tee connector that connects one of the multiple uprights to two of the multiple connecting beams, and a two-way connector that connects one of the multiple uprights to one of the multiple connecting beams.

[0032] The schematic scheme of the switch cabinet structure disclosed in this utility model is now described in detail with reference to the accompanying drawings. Although the drawings are provided to illustrate some embodiments of this utility model, the drawings are not necessarily drawn to the dimensions of the specific embodiments, and certain features may be enlarged, removed, or partially cut to better illustrate and explain the disclosure of this utility model. Some components in the drawings may be repositioned according to actual needs without affecting the technical effect. The phrase "in the drawings" or similar terms appearing in the specification do not necessarily refer to all drawings or examples.

[0033] Certain directional terms used in the description of the accompanying drawings below, such as “inner,” “outer,” “above,” “below,” and other directional terms, will be understood to have their normal meaning and refer to those directions as normally viewed in the accompanying drawings. Unless otherwise specified, the directional terms used in this specification are generally in accordance with the conventional directions understood by those skilled in the art.

[0034] The terms “first,” “first,” “second,” “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.

[0035] The terms "joining", "connection" and similar terms used in this utility model include both indirect connection of two components with the aid of an intermediate layer such as an adhesive or welding agent or an intermediate component such as a connector or transition piece, and direct connection of two components without the aid of any intermediate layer such as an adhesive or welding agent or an intermediate component such as a connector or transition piece.

[0036] Figures 1 to 8b The cabinet structure 100 of a switchgear is illustrated by way of example. In this example, the busbar compartment of the cabinet structure 100 is located on the top side of the cabinet structure 100, and the top busbar frame of the busbar compartment can be partially removed without affecting other structures. This facilitates the installation of the desired main busbar into the busbar compartment of the cabinet structure 100 from above, thereby greatly improving the main busbar assembly efficiency and significantly reducing the installation space required by the installers. As shown in the figure, the cabinet structure 100 may include a cabinet frame 10 and mounting components 20.

[0037] Specifically, such as Figure 1 As shown, the cabinet frame 10 can be arranged vertically and is generally rectangular in shape, with its top space serving as a busbar compartment for accommodating the main busbars. The cabinet frame 10 may include a frame body 11 and a top support frame. The frame body 11 is placed vertically, and the top support frame can be arranged generally horizontally at the top of the frame body 11 and supported by the frame body 11. Thus, the busbar compartment of the cabinet structure 100 occupies the top space of the frame body 11, and the top support frame located at the top of the frame body 11 can serve as a top busbar frame for installing a busbar compartment cover plate (not shown).

[0038] The top side support frame may include a top side support body and a pair of support beams 12. The support beams 12 may extend longitudinally, and the pair of support beams 12 may be arranged laterally opposite to each other and spaced apart, so that they can be respectively installed to the lateral ends of the top side support body. With the support beams 12 detachably connected to the frame body 11 by means of mounting components 20 below them, an operator can unlock the mounting components 20 using external tools, thereby allowing the support beams 12 located at the lateral ends of the top side support body to be removed from the top side support body. Figure 2 As shown, the operator can thus place the desired main busbar from top to bottom into the busbar compartment of the cabinet structure 100 from above.

[0039] The important thing is to combine Figure 3As shown, the support beam 12 may include an upper support plate 121 and a lower support plate 122. Both the upper support plate 121 and the lower support plate 122 extend longitudinally and are arranged vertically at intervals relative to each other. The upper support plate 121 may be provided with an operating opening 124 that extends vertically through it, and the lower support plate 122 may be provided with a connecting hole 123 that extends vertically through it. The cross-sectional shape of the operating opening 124 on a horizontal plane perpendicular to the vertical may surround the shape of the connecting hole 123, and the operating opening 124 may extend vertically to the connecting hole 123.

[0040] In this manner, the mounting component 20 can be fixedly mounted to the frame body 11 and extends upward from the lower support plate 122 through the connection hole 123 of the lower support plate 122. The mounting component 20 is thus detachably connected to the connection hole 123 of the lower support plate 122, thereby detachably connecting the support beam 12 to the frame body 11 via the mounting component 20. When it is necessary to unlock the mounting component 20, the operator can pass an external operating tool through the operating opening 124 of the upper support plate 121 from above the cabinet structure 100, i.e., above the support beam 12, to approach the connection hole 123 of the lower support plate 122. The external operating tool can then access the portion of the mounting component 20 extending upward from the lower support plate 122, thereby allowing the mounting component 20 to be unlocked.

[0041] Optionally, combined Figure 3 As shown, the support beam 12 may further include a connecting plate 125. The connecting plate 125 may extend longitudinally and be arranged substantially perpendicular to the upper support plate 121 and the lower support plate 122 between the upper support plate 121 and the lower support plate 122, thereby cooperating with the upper support plate 121 and the lower support plate 122 to form a C-shaped cross-section. Exemplarily, the support beam 12 may be designed as a C-shaped profile bent into shape, that is, the upper support plate 121, the connecting plate 125, and the lower support plate 122 of the support beam 12 may be integrally manufactured for ease of production. In embodiments not shown, the support beam 12 may also be designed as an I-shaped profile or a tubular profile, etc., as needed, as long as the above functions are achieved.

[0042] Optionally, combined Figure 4As shown, the mounting component 20 can be configured to include two pairs of mounting structures 21 corresponding to a pair of support beams 12, i.e., each pair of mounting structures 21 is fixed to the frame body 11 below the longitudinal ends of the corresponding support beam 12, thereby detachably connecting the corresponding support beam 12 to the frame body 11. Specifically, the mounting structure 21 may include mounting members 211 and fasteners (not shown). Mounting component 211 can be constructed as a bent sheet metal part, for example, it may include a first mounting plate 211a extending in a plane perpendicular to the vertical, a second mounting plate 211b extending in a plane perpendicular to the longitudinal direction, and a third mounting plate 211c extending in a plane perpendicular to the longitudinal direction. The first mounting plate 211a is arranged below the lower support plate 122 of the support beam 12 and is provided with a mating connection hole 211d corresponding to the connection hole 123 of the lower support plate 122. The second mounting plate 211b and the third mounting plate 211c can be fitted together to form a column shape adapted to the frame body 11. The third mounting plate 211c may be provided with mounting holes, on which bolts and other connecting parts can pass through and be fastened to the column of the frame body 11, thereby fixing the mounting component 211 to the frame body 11.

[0043] Fasteners extend from below the first mounting plate 211a, passing through the mating connection hole 211d on the first mounting plate 211a and the connection hole 123 of the lower support plate 122 of the support beam 12, and fasten the first mounting plate 211a and the support beam 12 together. Thus, the mounting member 211, fixedly mounted to the frame body 11, can be detachably connected to the support beam 12 via fasteners, thereby detachably connecting the support beam 12 to the frame body 11. Exemplarily, the fasteners can be bolts extending through the first mounting plate 211a and the lower support plate 122 of the support beam 12, with bolts extending above the lower support plate 122 of the support beam 12 engaging corresponding nuts. Tightening the nuts fastens the support beam 12 and the mounting member 211 together. When the support beam 12 needs to be removed from the top support body, an operating tool can engage the nut to remove it from the bolt, switching to an unlocked state, thereby allowing the removal of the support beam 12 for easier placement of the desired main busbar.

[0044] Optionally, combined Figure 5 As shown, the cabinet structure 100 may also include a busbar mounting frame 30. The busbar mounting frame 30 can be fixed generally longitudinally to the top space of the frame body 11, thereby clamping the main busbar extending laterally within it. When a pair of support beams 12 are removed from the lateral ends of the top support body, the operator can first install the main busbar into the busbar mounting frame 30, then install the busbar mounting frame 30 with the main busbar installed onto the top of the frame body 11. After installation is completed, the pair of support beams 12 can then be installed back onto the top support body.

[0045] Furthermore, the busbar mounting frame 30 may include an upper busbar clamping member 31, a busbar separator 32, and a lower busbar clamping member 33 for clamping the main busbar, and an upper busbar support member 34, a lower busbar support member 35, and a spacer support member 36 for mounting the upper busbar clamping member 31, the busbar separator 32, and the lower busbar clamping member 33 to the frame body 11. The lower busbar clamping member 33 may extend longitudinally and be fastened to the frame body 11, and the lower side of the lower busbar clamping member 33 may be provided with a mounting groove for fitting into the lower busbar support member 35. The lower busbar support member 35 is provided with four vertically extending and longitudinally spaced spacer support members 36, the top of which is fixedly connected to the upper busbar support member 34, so that the upper busbar support member 34 is fixedly connected to the lower busbar support member 35 by means of the spacer support members 36 and is vertically spaced relative to the lower busbar support member 35. Similar to the lower busbar clamp 33, the upper side of the upper busbar clamp 31 may also be provided with a mounting groove for fitting into the upper busbar support 34. Two spacer supports 36 located on both sides of the longitudinal direction are used to restrict the longitudinal movement of the lower busbar clamp 33. The two spacer supports 36 located in the middle of the longitudinal direction can extend through the upper busbar clamp 31, the busbar separator 32 and the lower busbar clamp 33. The spacer supports 36 can be arranged vertically between the upper busbar clamp 31 and the lower busbar clamp 33 and spaced apart from the upper busbar clamp 31 and the lower busbar clamp 33.

[0046] Busbar clamping slots 37 are provided on the lower side of the upper busbar clamping member 31, the upper and lower sides of the busbar separator 32, and the upper side of the lower busbar clamping member 33. The busbar clamping slots 37 on the upper busbar clamping member 31 and the upper busbar clamping slots 37 on the busbar separator 32 can cooperate to clamp the first busbar portion of the main busbar. The busbar clamping slots 37 on the lower busbar clamping member 33 and the lower busbar clamping slots 37 on the busbar separator 32 can cooperate to clamp the second busbar portion of the main busbar. Thus, the first busbar portion and the second busbar portion of the main busbar can be arranged vertically at intervals. The gap between the first busbar portion and the second busbar portion of the main busbar can be used to arrange busbar connectors. The busbar connectors can be fastened to the distribution busbar, for example, by bolting them to the distribution busbar. This allows the main busbar to be connected to the corresponding distribution busbar by means of busbar connectors without having to drill holes in the main busbar.

[0047] Preferably, the busbar separator 32 is movably arranged relative to the frame body 11, and the spacer support 36 extending through the busbar separator 32 can be used as a guide structure for adjusting the vertical movement of the busbar separator 32. Thus, the vertical spacing between the busbar separator 32 and the upper busbar clamp 31, as well as the vertical spacing between the busbar separator 32 and the lower busbar clamp 33, can be adjusted. This allows for clamping busbar portions of different specifications between the busbar separator 32 and the upper busbar clamp 31, and between the busbar separator 32 and the lower busbar clamp 33, allowing the installation of a first part and a second part of the main busbar with different specifications.

[0048] Optionally, combined Figure 6 As shown, the cabinet structure 100 may further include a secondary enclosure 40. The secondary enclosure 40 can be integrally arranged inside the frame body 11 in the space below the busbar compartment and isolated from the busbar compartment. The internal space of the secondary enclosure 40 installed to the frame body 11 can be constructed as the secondary compartment of the switchgear for installing various secondary devices. Compared with the conventional secondary compartment formed by arranging secondary partitions inside the cabinet frame 10 of the switchgear, the secondary enclosure 40 provided by the cabinet structure 100 of this utility model allows operators to install various secondary devices into the prefabricated secondary enclosure 40 before installation to the frame body 11, and then install the secondary enclosure 40 containing various secondary devices into the frame body 11 as a whole after the secondary devices are installed. This can greatly improve production efficiency.

[0049] When the operator plans to operate from the front of the switchgear, the secondary enclosure 40 can be installed on the longitudinal front side of the frame body 11, and its longitudinal front side can be provided as an installation opening 41. The operator can place the secondary components into the secondary enclosure 40 through the installation opening 41. It is understood that, in embodiments not shown, the installation position of the secondary enclosure 40 relative to the frame body 11 can be adjusted according to actual needs. For example, if the operator plans to operate from the lateral side, the secondary enclosure 40 can be installed inside the frame body 11 on the lateral side of the frame body 11 facing the operator, and its lateral side facing the operator can be provided as an installation opening 41, which only needs to achieve the above functions.

[0050] Optionally, such as Figure 1 As shown, the main frame 11 may include multiple columns and multiple connecting beams. The columns extend vertically and are spaced apart from each other in the horizontal and / or vertical directions. The connecting beams extend in a horizontal plane perpendicular to the vertical and connect to the columns in an orientation perpendicular to the columns, such that the columns and connecting beams cooperate to form a cuboid structure. Understandably, Figure 1 For ease of illustration, the cabinet structure 100 shown omits some sections of the vertical columns.

[0051] Specifically, the multiple columns may include the four corner columns forming the side edges of the cuboid structure, and the left center column 112a arranged between the left front corner column 111a and the left rear corner column 111c, and the right center column 112b arranged between the right front corner column 111b and the right rear corner column 111d. The multiple connecting beams may include a pair of bottom side crossbeams 113 and a pair of bottom side longitudinal beams 114 located on the top side of the cuboid structure and forming the bottom side support frame 11. The top side support frame includes a pair of top side crossbeams 115 and a pair of top side longitudinal beams 116, the length of the top side longitudinal beams 116 being shorter than that of the bottom side longitudinal beams 114. The left center column 112a and the right center column 112b extend upwards to connect with the front end of the corresponding top side longitudinal beam 116. The left support beam 12 can be connected to the left front corner column 111a and the left center column 112a via a pair of mounting structures 21. The right support beam 12 can be connected to the right front corner column 111b and the right center column 112b via a pair of mounting structures 21. Thus, the top of the pair of top side crossbeams 115, the pair of support beams 12, the pair of top side longitudinal beams 116, the top of the left center column 112a and the right center column 112b, and the two-way connector 50 and the three-way connector 60 described later can generally cooperate to form the top side support frame.

[0052] The multiple connecting beams may also include a front center crossbeam 117 and a supporting crossbeam 118. The front center crossbeam 117 is arranged between the left front corner column 111a and the right front corner column 111b among the four corner columns, and the supporting crossbeam 118 is arranged between the left center column 112a and the right center column 112b. The front center crossbeam 117 and the supporting crossbeam 118 can be used to arrange busbar partitions to divide the space above the busbar partitions of the frame body 11 into busbar compartments. The secondary enclosure 40 can be fixed to the area below the front center crossbeam 117 of the left front corner column 111a and the right front corner column 111b.

[0053] Optionally, the cabinet structure 100 may also include a two-way connector 50 and a three-way connector 60, both of which may be made of aluminum. This allows the cabinet structure 100 provided by the present invention to not only achieve welding-free assembly, simplify the production process, and improve the assemblability and stability of the entire cabinet, but also to cut off the magnetic closed loop, thereby effectively suppressing the eddy current effect and improving the temperature rise performance.

[0054] The two-way connector 50 is used to connect the corner posts adjacent to the support beam 12 and the corresponding connecting beams among the four corner posts. That is, the left front corner post 111a and the right front corner post 111b are both connected to the top side crossbeam 115 via the two-way connector 50. Figure 7a and Figure 7bTaking the two-way connector 50 used to connect the right front corner post 111b and the top side beam 115 as an example, the two-way connector 50 may include a two-way connector body 51 and two two-way connector segments 52 extending from different sides of the two-way connector body 51, such as the left side and the lower side. The two two-way connector segments 52 extend into the top side beam 115 and the right front post adjacent to the support beam 12, respectively, and are further fastened to the top side beam 115 and the right front post by means of bolts and other connecting accessories.

[0055] The tee connector 60 is used to connect the corner columns furthest from the supporting beam 12 to their corresponding connecting beams. Specifically, all four corner columns are connected to their corresponding bottom side crossbeams 113 and bottom side longitudinal beams 114 via the tee connector 60, and the left rear corner column 111c and right rear corner column 111d are connected to their corresponding top side crossbeams 115 and top side longitudinal beams 116 via the tee connector 60. Figure 8a and Figure 8b Taking the tee connector 60 used to connect the right rear corner post 111d to the corresponding top side crossbeam 115 and top side longitudinal beam 116 as an example, the tee connector 60 may include a tee connector body 61 and three tee connector segments 62 extending from different sides of the tee connector body 61, such as the front, left, and lower sides. The three tee connector segments 62 extend into the right rear corner post 111d and the corresponding top side crossbeam 115 and top side longitudinal beam 116, respectively, and are further fastened to the right rear corner post 111d and the corresponding top side crossbeam 115 and top side longitudinal beam 116 by means of bolts or other connecting accessories. It can be understood that... Figure 8b The longitudinal middle section of the top side longitudinal beam 116 shown is omitted for clarity.

[0056] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0057] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes, modifications, and combinations made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
