It typically incorporates a cabinet structure, integrating multiple electrical components (such as circuit breakers, load switches, fuses, etc.) into a single cabinet to form a node in a ring-shaped power supply network. The RMU is suitable for urban power distribution, industrial, and commercial power supply systems, enabling the distribution and protection of power.

[0003] In the prior art, when two ring network cabinets are installed outdoors, the lack of a positioning structure between them leads to insufficient connection between the two ring network cabinets, which causes shaking problems in subsequent work and reduces the stability of the ring network cabinets.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1-Figure 5 As shown, the utility model provides a positioning structure of a ring network cabinet, including two ring network cabinet bodies 1, a positioning column 2 is fixedly installed on one side of the outer wall of the two ring network cabinet bodies 1, a positioning socket 3 is opened on one side of the outer wall of the two positioning columns 2, three through holes 4 are opened on one side of the outer wall of the two positioning columns 2, two strip grooves 5 are opened on one side of the outer wall of the two ring network cabinet bodies 1, the inner surface walls of the four strip grooves 5 are movably embedded with strip sliders 6, two positioning plug-ins 7 are fixedly installed between one side of the outer wall of the four strip sliders 6, and the outer surface wall of one of the positioning plug-ins 7 is movably inserted into the inside of one of the positioning sockets 3, three first fixing holes 8 are opened on one side of the outer wall of the two positioning plug-ins 7, wherein the inner surface walls of the three first fixing holes 8 are threadedly connected with first bolts 9, and the outer surfaces of the three first bolts 9 are movably inserted into the inside of three of the through holes 4.

[0025] The effect achieved by the entire embodiment 1 is that when two ring network cabinet bodies 1 need to be put together outdoors, the two ring network cabinets can be accurately put together through the corresponding holes 13 opened on one side of the outer wall of one of the ring network cabinets and the two strip columns 14 installed on the opposite side of the outer wall of the other ring network cabinet. Since two strip grooves 5 are opened on the back of the ring network cabinet, and the two strip sliders 6 installed at the bottom of the positioning plug-in plate 7 are movably embedded in the two strip grooves 5, the positioning plug-in plate 7 behind one of the ring network cabinets is moved so that it is inserted into the positioning column 2 installed on the back of the other ring network cabinet and the positioning plug-in hole 3 opened on one side of the outer wall of the positioning column 2. At this time, the three first fixing holes 8 opened on the positioning plug-in plate 7 correspond to the three through holes 4 opened on the positioning column 2, and then through the action of the three first bolts 9, it passes through the three through holes 4 and is threadedly connected to the inside of the three first fixing holes 8, thereby accurately installing the two ring network cabinets together and making them fully connected. There will be no shaking in subsequent work, thereby improving the stability of work between the ring network cabinets.

[0026] Example 2: Figure 2-Figure 5 As shown, a second fixing hole 10 is provided on one side of the outer wall of the two ring network cabinet bodies 1, and a limiting hole 11 is provided on one side of the outer wall of the two positioning plug plates 7. The inner wall of one of the second fixing holes 10 is threadedly connected with a second bolt 12, and the outer wall of the second bolt 12 is movably inserted into the inside of the limiting hole 11. Two corresponding holes 13 are provided on one side of the outer wall of the two ring network cabinet bodies 1. Two strip columns 14 are fixedly installed on the other side of the outer wall of the two ring network cabinet bodies 1, and the outer walls of the two strip columns 14 are movably inserted into the inside of two corresponding holes 13. Shock-absorbing plates 15 are fixedly installed on the top of the two ring network cabinet bodies 1, and four shock-absorbing springs 16 are fixedly installed on the top of the two shock-absorbing plates 15. Four dampers 17 are fixedly installed on the top of the two shock-absorbing plates 15. Two protective plates 18 are fixedly installed between the tops of the eight shock-absorbing springs 16, and the tops of the eight dampers 17 are fixedly connected to the bottoms of the two protective plates 18.

[0027] The effect achieved by the entire embodiment 2 is that, since there is a positioning plate 7 on the back of each ring network cabinet, when one of the positioning plates 7 is not needed, the limiting hole 11 opened on the positioning plate 7 is made to correspond to the second fixing hole 10 opened on the back of the ring network cabinet, and then through the action of the second bolt 12, it passes through the limiting hole 11 and is threadedly connected to the inside of the second fixing hole 10, thereby limiting the unused positioning plate 7 to a suitable position. Secondly, shock-absorbing plates 15 are installed on the top of the two ring network cabinet bodies 1, and four shock-absorbing springs 16 and dampers 17 are installed between the two shock-absorbing plates 15 and the two protective plates 18, thereby effectively preventing foreign objects from hitting the top of the ring network cabinet, and playing a shock-absorbing and buffering effect, further improving the working stability between the ring network cabinets.

[0028] Working principle: First, when two ring network cabinets need to be put together outdoors, the two ring network cabinets can be initially put together through the two strip columns 14 installed on the opposite sides of the two ring network cabinets and the two corresponding holes 13. At this time, the positioning plate 7 behind one of the ring network cabinets is moved through the two strip grooves 5 and the two strip sliders 6. Since a positioning hole 3 is opened on one side of the outer wall of each positioning column 2, the positioning plate 7 is inserted into the positioning hole 3. Then, through the action of three first bolts 9, it passes through three through holes 4 and is threadedly connected to the inside of the three first fixing holes 8, thereby fixing the positioning plate 7 to the other ring network cabinet. The positioning column 2 on the upper part can accurately put the two ring network cabinets together and make them fully connected, so that there will be no shaking in the subsequent work. The other positioning plug plate 7 that is not needed is limited to a suitable position by the second bolt 12, the second fixing hole 10 and the limiting hole 11. Secondly, four shock-absorbing springs 16 and damping 17 are installed between the two shock-absorbing plates 15 and the two protective plates 18, so as to effectively prevent foreign objects from hitting the top of the ring network cabinet and have a shock-absorbing and buffering effect. In general, the positioning structure between the two ring network cabinets makes the two ring network cabinets fully connected, thereby improving the working stability between the ring network cabinets.
