[0034] In order to make the above-mentioned purposes, features and beneficial effects of the embodiments of the present utility model more obvious and easy to understand, the specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] The utility model provides a distributed DTU installation room for a ring network cabinet, which has a simple structure, is easy to manufacture and install.

[0036] Also refer to Figure 1 and Figure 2 , Figure 1 This is the assembly diagram of the distributed DTU installation room of the utility model ring main unit. Figure 2 This is a schematic diagram of its explosion.

[0037] The distributed DTU installation room of the ring main unit of the utility model comprises: a hexahedral frame 6 formed by bending a plate, and a door panel 2 detachably connected to the hexahedral frame 6 .

[0038] The hexahedral frame 6 includes a top surface, a bottom surface, a front surface, a back surface, a left side surface, and a right side surface, wherein the top surface and the back surface are closed structures, and the bottom surface, the front surface, the left side surface, and the right side surface are window structures.

[0039] The hexahedral frame 6 has a receiving cavity 11 for placing the distributed DTU.

[0040] Furthermore, in order to facilitate the placement of the distributed DTU, a DTU mounting plate 20 may be provided in the accommodating cavity 11. It should be noted that the DTU mounting plate 20 is independent of the hexahedral frame 6, so as to facilitate installation and removal.

[0041] Figure 3 A schematic diagram of a hexahedral frame of a distributed DTU installation room of a ring main unit of the present invention is shown.

[0042] The hexahedral frame 6 has a simple structure and can be formed by bending a sheet of material. Figure 4 yes Figure 3 Schematic diagram of the plate of the hexahedral framework shown.

[0043] The hexahedral frame 6 of this structure can greatly simplify the processing technology, and reduce the fastening connectors of the cabinet, making the distributed DTU installation room of the ring main unit of the utility model more solid and durable. Moreover, the installation room frame is basically rectangular when unfolded, and the part cut off from the original plate can be used as the processing material of other parts through reasonable arrangement, so as to reasonably utilize resources for the enterprise, reduce waste, and save material cost and processing cost.

[0044] like Figure 3 and Figure 4 As shown in FIG. 1 , one side of the plate corresponding to the front of the hexahedral frame has a protruding edge opposite to the other side, and the protruding edge is bent to form a door panel mounting portion 9. Figure 2 The door panel 2 is detachably mounted on the door panel mounting portion 9.

[0045] It should be noted that the plate may be made of metal or other suitable materials.

[0046] The distributed DTU installation room of the ring main unit provided by the utility model adopts a structure of a hexahedral frame formed by bending a plate and a door plate detachably connected to the hexahedral frame, and the top surface and the back surface are closed structures, and the bottom surface, front surface, left side surface, and right side surface are window structures; the distributed DTU is placed in the accommodating cavity of the hexahedral frame. This structure simplifies the processing technology, improves the production efficiency, and saves the plate; on the other hand, it reduces the fastening connectors, making it stronger and more durable.

[0047] Continue to refer to Figure 1 and Figure 2 In a non-limiting embodiment, the door panel 2 can be connected to the door panel mounting portion 9 in a rotatable manner through the door shaft bracket 4. For example, the door shaft bracket 4 is sleeved with the door shaft 3 and can rotate around the door shaft 3. One side of the door shaft bracket 4 is fixed to the door panel mounting portion 9 by a fastening screw 5, and the other side is fixed to the door panel 2.

[0048] The length and quantity of the door shaft support 4 and the door shaft 3 can be set arbitrarily, for example, Figure 2 The upper and lower structures are not limited to this embodiment of the utility model.

[0049] Of course, in a specific embodiment, the door axis bracket 4 may also have other structural forms, which is not limited to this.

[0050] It should be noted that Figure 2 In the illustrated embodiment, the door panel mounting portion 9 is arranged on the front left side of the hexahedral frame 6, i.e., a left outward opening door structure. In practical applications, the door panel mounting portion 9 can be designed according to the specific use environment and the layout of the surrounding ring network cabinets, etc., and can be arranged on any edge of the front of the hexahedral frame 6, for example, the door panel mounting portion 9 can be arranged on the front right side, upper side, and lower side of the hexahedral frame 6, i.e., a right outward opening door, an upper outward opening door, and a lower outward opening door structure, respectively.

[0051] When the distributed DTU installation room of the ring network cabinet provided by the utility model is used, it can usually be placed on the top plate of the ring network cabinet.

[0052] Most ring main units include primary equipment and secondary equipment, which are relatively independent. The primary equipment is used to connect the power supply and load, and is responsible for power transmission, transformation and distribution, while the secondary equipment controls and protects the primary equipment. Usually, the primary equipment and the secondary equipment are placed in two boxes from bottom to top. For the convenience of description, the two boxes are called the primary box and the secondary box. Correspondingly, the above-mentioned distributed DTU of the ring main unit can be placed on the top plate of the secondary box.

[0053] like Figure 5 The figure shows a schematic diagram of the structure of installing the distributed DTU installation room of the ring main unit of the utility model onto the top plate of the secondary box room.

[0054] Among them, the secondary box chamber 30 is also a hexahedral structure, the secondary box chamber left side plate 32 and the secondary box chamber right side plate 33 have the same structure, and the ring main unit distributed DTU installation room 100 is placed on the secondary box top plate 31.

[0055] Furthermore, in order to enhance its stability and safety of use, fixing holes 10 can be set at the bottom of both sides of the hexahedral frame 6, and the hexahedral frame 6 can be fixed by screws passing through the fixing holes 10, so that the distributed DTU installation room of the ring network cabinet can be firmly placed on the secondary box.

[0056] It should be noted that the number of the fixing holes 10 can be set arbitrarily and they are symmetrically distributed at the bottom of the left and right sides of the hexahedral frame 6 .

[0057] Continue to refer to Figure 5 The distributed DTU 40 can be placed on the DTU mounting plate 20. The height of the DTU mounting plate 20 can be designed to be fixed or adjustable to facilitate the use of distributed DTUs 40 of different heights, which is not limited.

[0058] Figure 6 and Figure 7 The top view before the distributed DTU is placed in the distributed DTU installation room of the ring main unit of the utility model and the cross-sectional schematic diagram after the distributed DTU is placed are respectively shown.

[0059] A first connection hole 21 is provided on the DTU installation plate 20, and the DTU installation plate 20 can be fixed to the top plate of the secondary box chamber of the ring main unit by using the first connection hole 21, for example, by using self-tapping screws.

[0060] A second connection hole 22 is also provided on the DTU mounting plate 20, and the distributed DTU can be fixed on the DTU mounting plate 20 by using the second connection hole 22, for example, by using a hexagonal bolt, a flat spring washer and a nut.

[0061] In order to distinguish the two connection holes with different functions, the first connection hole 21 and the second connection hole 22 can be designed to have different shapes, such as one is circular and the other is elliptical. In addition, in order to maintain the balance and stability of the connection, the first connection hole 21 and the second connection hole 22 can be evenly distributed in the four corners of the DTU mounting plate 20.

[0062] Continue to refer to Figure 1 , Figure 2 and Figure 5The distributed DTU 40 usually has a display screen 41 to display some data or waveforms, etc. In order to facilitate viewing of the displayed information, a see-through area 8 may be provided on the door panel 2. In a specific implementation, the see-through area 8 may be an opening on the door panel 2, and the position and size of the opening may be adapted to the display screen of the distributed DTU placed in the installation room, and this is not limited.

[0063] Furthermore, in order to enhance the dustproof effect, the opening may be covered with a transparent material, which can better maintain the hygiene of the installation room and does not affect the viewing of information on the DTU display screen 41.

[0064] In another non-limiting embodiment, in order to increase the adaptability of the distributed DTU installation room of the ring main unit of the utility model to various types of distributed DTUs, the door panel 2 can also be made of transparent material. In this way, there is no need to open a hole in the door panel 2, and the information on the DTU display screen can be easily viewed.

[0065] Furthermore, in order to ensure the safety of the use of distributed DTU, a door lock 1 can be set on the door panel 2. During normal operation, the door panel 2 is closed and locked by the door lock 1 to prevent unrelated personnel from moving it and ensure its safety. When maintenance is required, the door lock 1 is opened by authorized staff to complete the maintenance work.

[0066] The door lock 1 can be a rotary door lock, which has a simple structure and is easy to install. Of course, other door locks can also be used, which is not limited to this.

[0067] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative rather than limiting, unless otherwise stated. In specific implementations, the technical features of one or more dependent claims may be combined with the technical features of the independent claim, based on actual needs and where technically feasible, and the technical features from the corresponding independent claims may be combined in any appropriate manner rather than just by the specific combinations listed in the claims.

[0068] Although the utility model is disclosed as above, the utility model is not limited thereto.
