Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] See Figure 1-3 The present invention provides an integrated incoming and outgoing ring main unit 100, which includes a cabinet 10, an insulating gas box 20 disposed within the cabinet 10, and an incoming cable assembly 30 disposed on the insulating gas box 20. An outgoing cable assembly 40 is also disposed on the side of the cabinet 10 opposite to the incoming cable assembly 30. Below the incoming cable assembly 30 is an outgoing structure 50 for cables passing through the outgoing cable assembly 40 to exit the cabinet 10. The incoming cable assembly 30 and the outgoing cable assembly 40 are connected by a connecting component 60. By integrating the incoming cable assembly 30 and the outgoing cable assembly 40 within the cabinet 10 and connecting them using the connecting component 60, the number of cabinets 10 required can be significantly reduced, reducing the space occupied by the ring main unit. This is particularly suitable for space-constrained locations. Furthermore, by reducing the number of cabinets 10, manufacturing, transportation, installation, and maintenance costs can be effectively reduced, improving economic efficiency. Furthermore, the design can be customized according to the shape of the transformer 200 to achieve coordination and unity with the structure or shell of the transformer 200, enhancing the overall system integrity and aesthetics. At the same time, due to the compact structure of the cabinet 10, it can support multiple installation methods, making it easy to combine with other power distribution equipment and improve construction efficiency. In addition, by utilizing the outgoing cable structure 50, cables that pass through the incoming cable assembly 30, the connecting assembly 60 and the outgoing cable assembly 40 in sequence can pass through the outgoing cable structure 50 to exit the cabinet 10 and connect to the transformer 200, thereby effectively improving the convenience of connection operation.

[0024] like Figure 1 and Figure 2 As shown, the incoming cable assembly 30 includes several incoming cable front connectors 31 and several incoming cable sleeves 32. The incoming cable sleeves 32 are connected to the outgoing cable assembly 40 via a connecting assembly 60. In the embodiment provided by this utility model, the incoming cable assembly 30 includes three incoming cable sleeves 32, each of which is provided with an incoming cable front connector 31. The incoming cable head passes through the incoming cable front connector 31 and then into the incoming cable sleeve 32. The incoming cable front connector 31 provided by this utility model is provided with an inlet, and the incoming cable front connector 31 is rotatably connected to the incoming cable sleeve 32. By rotatably connecting the incoming cable front connector 31 to the incoming cable sleeve 32 and utilizing the inlet on the incoming cable front connector 31, top or bottom cable entry operations can be achieved, thereby meeting the usage requirements in various application scenarios.

[0025] like Figure 1 and Figure 2 As shown, the cable assembly includes several connecting copper pipes 61 and a circuit breaker 62 installed in the cabinet 10. The cables in the incoming cable assembly 30 are sequentially passed through the connecting copper pipes 61 and the circuit breaker 62, and then passed into the outgoing cable assembly 40. In the embodiment provided by this utility model, the number of connecting copper pipes 61 corresponds to the number of incoming cable sleeves 32, and the three connecting copper pipes 61 are arranged in a three-dimensional wiring design in the cabinet 10, forming ABC phase connecting copper pipes 61. By connecting the incoming cable sleeves 32 to the circuit breaker 62 using the connecting copper pipes 61, and connecting them using the outgoing cable assembly of the circuit breaker 62, the operation of the incoming and outgoing circuits can be realized in a shared compartment arrangement within a cabinet 10 unit, thereby significantly reducing the number of cabinets 10 required, reducing the space occupied by the ring main unit, and making the cabinet 10 structure compact.

[0026] like Figure 1As shown, the outgoing cable assembly 40 includes several outgoing cable front connectors 41 and outgoing cable sleeves 42, and the number of outgoing cable sleeves 42 corresponds to the number of connecting copper pipes 61. The cable head passes through the connecting copper pipe 61 and the circuit breaker 62, and then enters the outgoing cable sleeve 42 and the outgoing cable front connector 41. The outgoing cable front connector 41 provided by this invention is provided with an outgoing port, and the outgoing cable front connector 41 is rotatably connected to the outgoing cable sleeve 42. By rotatably connecting the outgoing cable front connector 41 to the outgoing cable sleeve 42 and utilizing the outgoing port on the outgoing cable front connector 41, top or bottom cable outgoing operations can be achieved, thereby meeting the usage requirements in various application scenarios. In addition, the cabinet 10 provided by this utility model is provided with a top cable hole 11 at the top and a bottom cable hole at the bottom. By using the top cable hole 11 and the bottom cable hole, the transformer 200 can be connected to the top or bottom of the cabinet 10 for cable entry or exit, thereby further meeting the needs of cable entry or exit operations in various usage scenarios and improving the convenience of cable entry or exit operations.

[0027] like Figure 1 and Figure 3 As shown, the outgoing cable structure 50 is a side-outgoing cable hole. Cables passing through the outgoing cable sleeve 42 enter the transformer 200 through the side-outgoing cable hole. By utilizing the side-outgoing cable hole, it is possible to exit the cable from the side of the cabinet 10 and connect it to the transformer 200, thereby further enriching the application requirements of the outgoing cable operation of this integrated incoming and outgoing ring main unit 100.

[0028] like Figure 1 As shown, the cabinet 10 also includes a backpack 12, a cable compartment 13, and an operating mechanism 14. The backpack 12 and the cable compartment 13 can effectively store the cables inside the cabinet 10, thereby improving the aesthetics of the cabinet 10 and enhancing cable safety. Furthermore, the operating mechanism 14 can effectively improve the convenience for operators to operate the integrated incoming and outgoing ring main unit 100.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
