Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switch cabinet technology, specifically relating to a top-outlet drawer-type switch cabinet partition. Background Technology
[0002] With market changes, customers now have increasingly higher requirements for complete switchgear, especially the safety protection level of switchgear. Many projects require the internal compartments of the cabinet to meet the 3B requirement, especially drawer cabinets, which require the main busbar compartment and the lower cable compartment to be separated.
[0003] Currently, the partition between the main busbar compartment and the lower cable compartment of drawer-type switchgear is a single piece. Because the secondary components of the drawer are not on the same horizontal plane as the upper surface of the vertical passage, and the height of the secondary components is higher than the upper surface of the vertical passage, it is difficult to meet the IP20 requirement (the equipment provides protection against objects with a diameter greater than 12.5 mm and prevents fingers from touching internal parts). Due to the height difference between the top surface of the passage and the busbar compartment partition, some vertical copper busbars are exposed, posing a safety hazard. Furthermore, for switchgear with top-outlet drawer circuits, the cables for the primary components in the unit drawer are led out from the top of the switchgear, passing through the busbar compartment partition and sharing the same compartment as the main busbar, posing a safety hazard and making cable routing difficult. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a top-outlet drawer-type switch cabinet partition and switch cabinet in view of the shortcomings of the existing technology. The primary cable in the unit drawer can be led out from the top of the switch cabinet through the cable compartment, so that the primary cable is isolated from the main bus, reducing safety hazards and operation difficulty.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] A top-outlet drawer-type switchgear partition includes: a busbar compartment rear sealing plate, a passageway top sealing plate, and a secondary plug-in top sealing plate. The busbar compartment rear sealing plate is vertically arranged, and the passageway top sealing plate and the secondary plug-in top sealing plate are horizontally arranged. The passageway top sealing plate and the secondary plug-in top sealing plate are respectively connected to the lower side of the front part of the busbar compartment rear sealing plate.
[0007] Furthermore, the bottom surface of the channel top sealing plate is lower than the bottom surface of the busbar chamber rear sealing plate, and the bottom surface of the channel top sealing plate is provided with vertical clearance holes.
[0008] Furthermore, the busbar chamber rear sealing plate, the channel top sealing plate, and the secondary plug-in top sealing plate are all integrally bent from steel plates.
[0009] Furthermore, the edge of the busbar chamber rear sealing plate is bent forward to form a side, and the edges of the channel top sealing plate and the secondary plug-in top sealing plate are both bent upward to form a side.
[0010] Furthermore, the four sides of the channel top sealing plate are all bent upwards, and the side closest to the secondary plug-in top sealing plate is lower than the other sides. The secondary plug-in top sealing plate is bent upwards on three sides of the bottom surface to form sides, and the bottom edge of the unbent side abuts against the upper edge of the lower side of the channel top sealing plate.
[0011] Furthermore, top plate supports for connecting to the top plate of the switchgear are respectively provided on both sides of the upper end of the busbar compartment rear cover plate.
[0012] Furthermore, the busbar compartment rear sealing plate is provided with a zero-row through hole, and a through hole insulating partition can be detachably installed on the busbar compartment rear sealing plate. There are two zero-row through holes, and two corresponding through hole insulating partitions are provided, each located behind the two zero-row plug-in clearance holes.
[0013] Furthermore, the busbar chamber rear sealing plate has a wire-passing hole, and a protective coil is installed in the wire-passing hole.
[0014] Furthermore, the secondary plug-in top sealing plate has a wiring clearance hole, and a clearance hole insulating partition is detachably installed on the secondary plug-in top sealing plate, the clearance hole insulating partition being located below the wiring clearance hole.
[0015] A switch cabinet includes a main busbar compartment, a vertical enclosed passage, a cable compartment, and a top-outlet unit drawer mounted on a cabinet frame. The main busbar compartment and the cable compartment are separated by the aforementioned top-outlet drawer-type switch cabinet partition.
[0016] After adopting the above technical solution, the beneficial effects of this utility model are:
[0017] The utility model discloses a top-outlet drawer-type switchgear partition and switchgear in which the busbar compartment rear sealing plate, the passage top sealing plate and the secondary plug-in top sealing plate are connected and assembled into a whole, completely separating the upper and lower and rear parts. The primary plug-in cable in the unit drawer can be led out from the top of the switchgear through the cable compartment, so that the primary cable is isolated from the main busbar, reducing safety hazards and operational difficulties.
[0018] In this invention, because the bottom surface of the channel top sealing plate is low, it can be fixedly connected to the upper surface of the vertical row enclosed channel of the switch cabinet, thereby sealing off all exposed parts of the live copper busbars, solving the problem of exposed vertical copper busbars, and fully meeting the 3B requirements and the IP20 protection level requirements of the compartments inside the cabinet.
[0019] In this utility model, the busbar chamber rear sealing plate, the channel top sealing plate, and the secondary plug-in top sealing plate are all formed by bending steel plates in one piece. The top sealing plates are connected to each other through the side edges, which enhances the overall strength.
[0020] In this invention, the secondary plug-in top sealing plate has side edges on only three sides. The bottom edge of the side without side edges abuts against the upper edge of one side of the channel top sealing plate. This avoids the vertical copper busbars extending from the vertical busbar avoidance holes, ensuring the electrical safety distance between the large-size vertical copper busbars and the secondary plug-in top sealing plate.

[0028] In the description of this specification, unless otherwise expressly defined, the terms "setting", "installation", "connection", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.
[0029] Example 1:
[0030] like Figure 1 As shown, a top-outlet drawer-type switchgear partition 1 includes: a busbar compartment rear sealing plate 11, a passageway top sealing plate 12, and a secondary plug-in top sealing plate 13. The busbar compartment rear sealing plate 11 is vertically arranged, while the passageway top sealing plate 12 and the secondary plug-in top sealing plate 13 are horizontally arranged. The passageway top sealing plate 12 and the secondary plug-in top sealing plate 13 are respectively connected to the lower side of the front part of the busbar compartment rear sealing plate 11 (in this application, "front part" refers to...). Figure 3 The side where the unit drawer 25 is installed on the switchgear 2 ("rear" refers to the side away from the unit drawer 25). The busbar compartment rear sealing plate 11, the passage top sealing plate 12, and the secondary plug-in top sealing plate 13 are connected and assembled into a whole, completely separating the upper, lower, and rear parts. The cables of the primary plug-in in the unit drawer can be led out from the top of the switchgear through the cable compartment, so that the primary cables are isolated from the main busbar, reducing safety hazards and operational difficulties.
[0031] Furthermore, the bottom surface of the channel top sealing plate 12 is lower than the bottom surface of the busbar compartment rear sealing plate 11 and the secondary plug-in top sealing plate 13, and the bottom surface of the channel top sealing plate 12 is provided with vertical row clearance holes 121. When the partition 1 is installed on the switch cabinet 2, the bottom surface of the channel top sealing plate 12 can be fixedly connected to the upper surface of the vertical row enclosed channel 23 of the switch cabinet 2, thereby solving the problem of exposed vertical copper busbars 231.
[0032] like Figure 2 As shown, the busbar compartment rear cover plate 11, the passageway top cover plate 12, and the secondary plug-in top cover plate 13 are all integrally bent from steel plates. Specifically, the edge of the busbar compartment rear cover plate 11 is bent forward to form a side, and the edges of the passageway top cover plate 12 and the secondary plug-in top cover plate 13 are bent upward to form a side, for connecting with each other and for structural connection and fixation to the switchgear 2. After the busbar compartment rear cover plate 11, the passageway top cover plate 12, and the secondary plug-in top cover plate 13 are connected and assembled into a whole, they have high overall strength.
[0033] To better illustrate the inventive concept of this application, the structure of each top sealing plate is described below.
[0034] like Figure 1 and Figure 2As shown in the figure, in this utility model, only the upper and left and right edges of the busbar compartment rear cover plate 11 are bent forward, and the upper side of the busbar compartment rear cover plate 11 is formed by bending twice, which has a better electrical isolation effect. The upper side and bottom surface of the busbar compartment rear cover plate 11 have self-tapping screw holes for connecting and fixing to the cabinet frame 21 of the switch cabinet 2.
[0035] The busbar compartment rear cover plate 11 has top plate brackets 115 on both sides of its upper end for connecting to the top plate of the switchgear. The top plate brackets 115 are located on the rear side of the busbar compartment rear cover plate 11.
[0036] The busbar compartment rear cover plate 11 has a neutral row through hole 111. A through hole insulating partition 112 is detachably installed on the busbar compartment rear cover plate 11. Two neutral row through holes 111 are spaced apart on the left and right sides, and two corresponding through hole insulating partitions 112 are located behind each of the two neutral row through holes 111. The through hole insulating partitions 112 provide electrical isolation. The manufacturer can choose to remove one of the through hole insulating partitions 112 depending on whether the neutral row is positioned to the left or right.
[0037] Furthermore, a cable passage hole 113 is also provided on the bottom surface of the busbar compartment rear sealing plate 11. The cable passage hole 113 is specifically located at the corner of the bottom surface. There can be one or more, and the technician can decide the number to be provided as needed. In this embodiment, two are used as an example for illustration. A protective coil 114 is provided in the cable passage hole 113. The protective coil 114 is generally a rubber ring, which is used to protect the passing cables and reduce wear.
[0038] In this utility model, the top sealing plate 12 of the channel is bent upward on all four sides of the bottom surface to form side edges. One side edge is connected and fixed to the lower edge of the busbar compartment rear sealing plate 11 by a self-tapping screw. The other two side edges have self-tapping screw holes for connecting and fixing to the cabinet frame 21 of the switch cabinet 2. The side edge closer to the secondary plug-in top sealing plate 13 is lower in height than the other side edges and does not have a self-tapping screw hole.
[0039] The bottom surface of the channel top sealing plate 12 has self-tapping holes for fixed connection with the upper surface of the vertical row enclosed channel 23 of the switch cabinet 2. The vertical row clearance hole 121 on the channel top sealing plate 12 extends to the outside through the front side for the vertical copper busbar 231 in the vertical row enclosed channel 23 to pass through.
[0040] In this utility model, the secondary plug-in top sealing plate 13 is bent upward on three sides of the bottom surface to form side edges. One side edge is connected and fixed to the lower edge of the busbar compartment rear sealing plate 11 by a self-tapping screw. The other two side edges have self-tapping screw holes for connection and fixing to the cabinet frame 21 of the switch cabinet 2. The bottom edge of the side that is not bent, that is, the side closest to the channel top sealing plate 12, abuts against the upper edge of the lower side of the channel top sealing plate 12.
[0041] The secondary plug-in top sealing plate 13 does not have a side edge on the side near the channel top sealing plate 12, which can avoid the vertical copper busbar 231 extending from the vertical busbar avoidance hole 121, ensuring the electrical safety distance between the large-size vertical copper busbar 231 and the secondary plug-in top sealing plate 13.
[0042] Furthermore, the secondary plug-in top sealing plate 13 has a wiring clearance hole 131, and a clearance hole insulating partition 132 is detachably installed on the secondary plug-in top sealing plate 13. The clearance hole insulating partition 132 is located above the wiring clearance hole 131, making it convenient for the manufacturer to remove it for wiring.
[0043] Example 2:
[0044] like Figure 3 and Figure 4 As shown, a switchgear 2 includes a cabinet frame 21 and a main busbar compartment 22, a vertical enclosed channel 23, a cable compartment 24, and a top-outlet unit drawer 25 disposed on the cabinet frame 21. A top-outlet drawer-type switchgear partition 1, as described in Embodiment 1, is installed on the cabinet frame 21 between the main busbar compartment 22 and the cable compartment 24. The primary cables in the unit drawer 25 can be led out from the top of the switchgear through the cable compartment 24, bypassing the main busbar compartment 22, thereby isolating the primary cables from the main busbar and reducing safety hazards and operational difficulties.
[0045] The bottom surface of the channel top sealing plate 12 is fixedly connected to the upper surface of the vertical busbar closed channel 23, and the vertical copper busbar 231 in the vertical busbar closed channel 23 passes through the vertical busbar clearance hole 121 on the channel top sealing plate 12. The partition 1 completely separates the upper main busbar chamber 22 from the lower vertical busbar closed channel 23 and the rear cable chamber 24.
[0046] The wiring of the secondary plug-in 251 on the unit drawer 25 can be passed through the wiring clearance hole 131 on the top cover plate 13 of the secondary plug-in. The neutral bus in the cable compartment 24 passes through the neutral bus through hole 111 on the rear cover plate 11 of the busbar compartment.
[0047] The cabinet frame 21 includes an upper mounting frame 211, which consists of an upper horizontal beam and left and right vertical beams. The three sides of the busbar compartment rear sealing plate 11 are respectively connected and fixed to the upper horizontal and vertical beams of the mounting frame 211. The unit drawer 25 has a shelf 26 above it. The front sides of the passage top sealing plate 12 and the secondary plug-in top sealing plate 13 are connected and fixed to the shelf 26 by self-tapping screws. The top plate bracket 115 of the shelf 1 is connected and fixed to the top plate of the switch cabinet 2.
[0048] The top-outlet drawer-type switchgear partition and switchgear of this utility model are assembled into a whole partition by connecting and assembling a rear sealing plate of the vertically arranged busbar compartment and a top sealing plate of the horizontally arranged passage and a top sealing plate of the secondary plug-in, which completely separates the upper, lower and rear parts. The cables of the primary plug-in in the unit drawer can be led out from the top of the switchgear through the cable compartment, so that the primary cables are isolated from the main busbar, thereby reducing safety hazards and operational difficulties.
[0049] While specific embodiments of this utility model have been described above, those skilled in the art should understand that the described embodiments are merely some, not all, embodiments of this utility model. These are merely illustrative examples, and the scope of protection of this utility model is defined by the claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model and without any inventive effort, but all such changes and modifications fall within the scope of protection of this utility model.
