Description

Technical Field

[0001] This utility model belongs to the field of switch cabinet technology, specifically relating to a bottom-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 the drawer-type switchgear is a single piece. Because the secondary plug-in of the drawer and the upper surface of the vertical channel are not on the same horizontal plane, and the height of the secondary plug-in is higher than the upper surface of the vertical channel, it is difficult for the compartment to meet the IP20 requirement (the equipment is protective against objects with a diameter greater than 12.5 mm and can prevent fingers from touching the internal parts). Due to the height difference between the top surface of the channel and the busbar compartment partition, some vertical copper busbars are exposed, posing a safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bottom-out drawer-type switch cabinet partition and switch cabinet that can completely seal all exposed parts of the live copper busbars and has good protection effect between the compartments inside the cabinet, in order to address the shortcomings of the existing technology.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A bottom-outlet drawer-type switchgear partition includes: a cable compartment top sealing plate, a passage top sealing plate, and a secondary plug-in top sealing plate. The cable compartment top sealing plate, the passage top sealing plate, and the secondary plug-in top sealing plate are all horizontally arranged. The passage top sealing plate and the secondary plug-in top sealing plate are respectively connected to one side of the cable compartment top sealing plate. The bottom surface of the passage top sealing plate is lower than the bottom surfaces of the cable compartment top sealing plate and the secondary plug-in top sealing plate. The bottom surface of the passage top sealing plate is provided with vertical clearance holes.

[0007] Furthermore, the cable compartment top sealing plate, the channel top sealing plate, and the secondary plug-in top sealing plate are all integrally bent from steel plates.

[0008] Furthermore, both the cable compartment top sealing plate and the channel top sealing plate are bent upwards around the bottom surface to form side edges.

[0009] Furthermore, the secondary plug-in top sealing plate is bent upward on three sides of the bottom surface to form side edges, and the bottom edge of the unbent side abuts against the upper edge of one side of the channel top sealing plate.

[0010] Furthermore, one side of the channel top sealing plate and the secondary plug-in top sealing plate are respectively connected to one side of the cable chamber top sealing plate by self-tapping screws, and self-tapping screw holes are respectively opened on the side of the cable chamber top sealing plate, the channel top sealing plate, the secondary plug-in top sealing plate, and the bottom surface of the channel top sealing plate.

[0011] Furthermore, the cable compartment top sealing plate has a zero-row through hole, and an insulating partition with the through hole can be detachably installed on the cable compartment top sealing plate. The zero-row through hole is an elongated hole, and two insulating partitions with the through hole are provided and are located side by side below the zero-row through hole.

[0012] Furthermore, the cable compartment top sealing plate has a wire passage hole, and a protective coil is installed in the wire passage hole.

[0013] 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.

[0014] A switch cabinet includes a main busbar compartment, a vertical enclosed channel, a cable compartment, and a bottom-outlet unit drawer mounted on a cabinet frame. The main busbar compartment and the cable compartment are connected by the aforementioned bottom-outlet drawer-type switch cabinet partition. The bottom surface of the channel top sealing plate is fixedly connected to the upper surface of the vertical enclosed channel.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] The bottom-outlet drawer-type switchgear partition and switchgear disclosed in this utility model are assembled into a whole by connecting the cable compartment top sealing plate, the channel top sealing plate and the secondary plug-in top sealing plate, which completely separates the upper and lower parts. Since the bottom surface of the channel top sealing plate is low, it can be fixedly connected to the upper surface of the vertical row closed channel of the switchgear, which can completely seal all exposed parts of the live copper busbars, solve the problem of exposed vertical copper busbars, and fully meet the 3B requirements and the IP20 protection level requirements of the compartments inside the cabinet.

[0017] In this utility model, the cable compartment top 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.

[0018] 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.

[0019] In this utility model, since the zero-row is installed at the front and the zero-row is installed at the back of different manufacturers, the zero-row through hole is set as an elongated hole for uniformity. The process is simple. In order to facilitate the manufacturer to make the hole, the second insulating plate is made into two pieces. Only one piece needs to be removed when using it. It has strong versatility and is easy to use. Attached Figure Description

[0028] Example 1:

[0029] like Figure 1 As shown, a bottom-outlet drawer-type switchgear partition 1 includes: a cable compartment top sealing plate 11, a passage top sealing plate 12, and a secondary plug-in top sealing plate 13. The cable compartment top sealing plate 11, the passage top sealing plate 12, and the secondary plug-in top sealing plate 13 are all horizontally arranged. The passage top sealing plate 12 and the secondary plug-in top sealing plate 13 are respectively connected to one side of the cable compartment top sealing plate 11. The cable compartment top sealing plate 11, the passage top sealing plate 12, and the secondary plug-in top sealing plate 13 are interconnected and assembled into a whole, completely separating the upper and lower parts.

[0030] The bottom surface of the channel top sealing plate 12 is lower than the bottom surface of the cable compartment top sealing plate 11 and the secondary plug-in top sealing plate 13. 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.

[0031] like Figure 2 As shown, the cable compartment top sealing plate 11, the passage top sealing plate 12, and the secondary plug-in top sealing plate 13 are all integrally bent from steel plates. Specifically, each top sealing plate has its bottom perimeter edge bent upwards to form a side, which is used for connecting with each other and for structural connection and fixation to the switch cabinet 2. After the cable compartment top 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, they have high overall strength.

[0032] To better illustrate the inventive concept of this application, the structure of each top sealing plate is described below.

[0033] like Figure 1 and Figure 2 As shown in the figure, in this utility model, the cable compartment top sealing plate 11 is bent upward around the bottom to form side edges. One side edge is connected and fixed to the channel top sealing plate 12 and the secondary plug-in top sealing plate 13 by self-tapping screws. The other two opposite side edges have self-tapping screw holes for connecting and fixing to the cabinet frame 21 of the switch cabinet 2.

[0034] The bottom surface of the cable compartment top sealing plate 11 has a zero-row through hole 111. A through-hole insulating partition 112 is detachably installed on the cable compartment top sealing plate 11. The zero-row through hole 111 is an elongated hole connecting the mounting positions of two zero rows. Two through-hole insulating partitions 112 are provided side-by-side below the zero-row through hole 111, with one through-hole insulating partition 112 corresponding to each mounting position. The through-hole insulating partitions 112 provide electrical isolation, and the manufacturer can choose to remove one of the through-hole insulating partitions 112 as needed.

[0035] Furthermore, a cable passage hole 113 is also provided on the bottom surface of the cable compartment top sealing plate 11. The cable passage hole 113 is specifically located at the corner of the bottom surface. There can be one or more holes, and the technician can decide the number of holes as needed. In this embodiment, three holes are used as an example for illustration. A protective coil 114 is provided inside the cable passage hole 113. The protective coil 114 is generally a rubber ring, which is used to protect the cable passing through and reduce wear.

[0036] In this utility model, the channel top sealing plate 12 is bent upward around the bottom to form a side. One side is connected and fixed to one side of the cable compartment top sealing plate 11 by a self-tapping screw. The other two sides have self-tapping screw holes for connection and fixation to the cabinet frame 21 of the switch cabinet 2. The side closer to the secondary plug-in top sealing plate 13 is lower in height than the other sides and does not have a self-tapping screw hole.

[0037] 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.

[0038] 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 one side edge of the cable compartment top sealing plate 11 by a self-tapping screw. The other two side edges have self-tapping screw holes for connection and fixation 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 edge of the channel top sealing plate 12.

[0039] 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.

[0040] Furthermore, the bottom surface of the secondary plug-in top sealing plate 13 is provided with a wiring avoidance hole 131 for avoiding wiring of the secondary plug-in. A avoidance hole insulating partition 132 is detachably installed on the secondary plug-in top sealing plate 13. The avoidance hole insulating partition 132 is located below the wiring avoidance hole 131, making it convenient for the manufacturer to remove it for wiring.

[0041] Example 2:

[0042] like Figure 3 and Figure 4 As shown in the figure, a switch cabinet 2 includes a cabinet frame 21 and a main busbar compartment 22, a vertical enclosed channel 23, a cable compartment 24 and a bottom-outlet unit drawer 25 disposed on the cabinet frame 21. The bottom-outlet drawer type switch cabinet partition 1 of Embodiment 1 is installed on the cabinet frame 21 between the main busbar compartment 22 and the cable compartment 24.

[0043] The unit drawer 25 has a shelf 26 above it. The front side of the shelf 1, namely the front side of the passage top sealing plate 12 and the secondary plug-in top sealing plate 13, is connected and fixed to the shelf 26 by self-tapping screws. In this application, "front" refers to the side of the switch cabinet 2 where the unit drawer 25 is installed. The left and right sides of the shelf 1 are respectively connected and fixed to the cabinet frame 21 by self-tapping screws.

[0044] The bottom surface of the channel top sealing plate 12 is fixedly connected to the upper surface of the vertical row enclosed channel 23. The vertical copper busbar 231 in the vertical row enclosed channel 23 passes through the vertical row clearance hole 121 on the channel top sealing plate 12. The wiring of the secondary plug-in 251 on the unit drawer 25 can pass through the wiring clearance hole 131 on the secondary plug-in top sealing plate 13. The neutral busbar in the cable compartment 24 passes through the neutral busbar through hole 111 on the cable compartment top sealing plate 11.

[0045] This utility model discloses a bottom-outlet drawer-type switchgear partition and switchgear. By setting up a partition composed of a cable compartment top sealing plate, a channel top sealing plate, and a secondary plug-in top sealing plate connected and assembled into an integral whole, the main busbar compartment and the cable compartment are completely separated. The bottom surface of the channel top sealing plate is fixedly connected to the upper surface of the vertical row of closed channels of the switchgear, thereby sealing off all exposed parts of the live copper busbars, meeting the 3B requirements and the IP20 protection level requirements between compartments in the cabinet, and enhancing the overall strength of the partition.

[0046] 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.
