DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The ring network switch cabinet provided by the embodiment of the present invention is as follows: Figures 1 to 3 As shown, it includes: an air box 2, a cabinet 14, a first switch 8, a second switch 10, a first switch power input mechanism 1, a second switch power input mechanism 3, a busbar 9, a first inlet and outlet bushing 7 and a second inlet and outlet bushing;

[0036] The gas box 2 is installed in the cabinet 14. The structure of the gas box 2 can be seen in FIG. Figure 5 As shown; the first switch 8 and the second switch 10 are respectively installed in the air box 2 and are overlapped by the busbar 9; the first switch power input mechanism 1 is installed outside the air box 2, and its output end is transmission connected with the first switch 8; the second switch power input mechanism 3 is installed outside the air box 2, and its output end is transmission connected with the second switch 10; the first input and output line bushing 7 is penetrated through the box wall of the air box 2, and its inner end is electrically connected with the first switch 8, and the outer end is located in the cabinet 14; the second input and output line bushing is penetrated through the box wall of the air box 2, and its inner end is electrically connected with the second switch 10, and the outer end is located in the cabinet 14.

[0037] It should be noted that if Figure 4 As shown, the two inlet and outlet bushings of this solution are both three-phase inlet and outlet bushings. In addition, this solution transmits the opening and closing triggering action to the switch through the switch power input mechanism to trigger the opening and closing of the switch, and the two switch power input mechanisms are both located in the cabinet 14. In addition, this solution configures two switches in one gas box 2, and two switch power input mechanisms and two inlet and outlet bushings are correspondingly provided for the two switches, so as to meet the customer's multi-scheme overlap requirements. In other words, this solution optimizes the design concept of the ring network switch cabinet and configures it with two sets of switch mechanisms to form a new ring network switch cabinet, fill the gap in the ring network switch cabinet, improve the scope of application of the ring network switch cabinet, and improve the versatility of the ring network switch cabinet. Of course, the design of the ring network switch cabinet of this solution meets the technical requirements of the State Grid.

[0038] It can be seen from the above technical solution that the ring network switch cabinet provided by the embodiment of the present invention is equipped with two switches in one gas box, and each switch is provided with a switch power input mechanism and an inlet and outlet wire bushing to form two groups of switch mechanisms, which can not only meet the needs of matching customers' different combination solutions, but also help to improve the space utilization of the open ring network switch cabinet.

[0039] In this solution, in order to realize the quick connection of the second inlet and outlet bushings, Figure 4 As shown, the second inlet and outlet sleeve is a quick-insert sleeve 6.

[0040] Specifically, if Figure 1 As shown, the gas box 2 is installed on the top of the cabinet 14; the quick-insert sleeve 6 is provided through the lower box wall of the gas box 2, and its outer end is close to the rear side wall of the cabinet 14;

[0041] like Figure 6 As shown, the ring network switch cabinet also includes:

[0042] The rear door panel 6.13, which is provided on the rear side wall of the cabinet body 14, can be opened and closed. The rear door panel 6.13 has a first wire hole 6.11. This design not only facilitates the wiring of the quick-connect sleeve 6, but also prevents people from accidentally approaching the quick-connect sleeve 6, thereby ensuring the safety of the ring network switch cabinet.

[0043] Furthermore, if Figure 6 As shown, the rear door panel 6.13 is hinged to the rear side wall of the cabinet body 14 and is opened and closed with the rear side wall of the cabinet body 14 by the electromagnetic lock 6.12 with handle. This design not only facilitates the rapid opening and closing of the rear door panel 6.13, but also helps to ensure the safety of opening and closing the rear door panel 6.13. In addition, the unlocking instructions of the electromagnetic lock 6.12 with handle of the rear door panel 6.13 can be referred to as follows Figure 11 Instructions shown.

[0044] Furthermore, a second wire hole is provided on the lower wall of the cabinet 14;

[0045] The ring network switch cabinet also includes: a first quick-connect sleeve connecting busbar 6.1 and a second plug-in sleeve connecting busbar 6.2; Figure 7 As shown, one end of the first quick-connect sleeve connecting busbar 6.1 is connected to the outer end of the quick-connect sleeve 6, and the other end passes through the first wire hole 6.11 to the rear of the cabinet 14; one end of the second quick-connect sleeve connecting busbar 6.2 is connected to the outer end of the quick-connect sleeve 6, and the other end passes through the second wire hole to the bottom of the cabinet 14. This solution is designed in this way to facilitate the extension of the quick-connect sleeve 6 for wiring, which not only improves the convenience of wiring the quick-connect sleeve 6, but also expands the applicable wiring scenarios of the quick-connect sleeve 6. In addition, as Figure 7 As shown, the inner end of the first quick-insert sleeve connecting busbar 6.1 and the inner end of the second plug-in sleeve connecting busbar 6.2 are essentially first connected to the outer end of the quick-insert sleeve 6. Figure 7 As shown, the top extension busbar 4.1 can extend to the left and right sides of the top extension bushing 4. The first inlet and outlet bushing 7 can be connected through the first inlet and outlet bushing connecting busbar 7.1, and can also be connected to the electrical device 7.21 through the second inlet and outlet bushing connecting busbar 7.2.

[0046] In this solution, in order to ensure that the electrical safety distance between the two switches meets the requirements, the first switch 8 and the second switch 10 are diagonally distributed in the gas box 2.

[0047] Specifically, if Figure 2 As shown, one of the first switch 8 and the second switch 10 is located at the upper left corner of the air box 2, and the other is located at the lower right corner of the air box 2. This arrangement of the two switches in this solution facilitates the front-mounted design of the power input mechanisms of the two switches, facilitating operator operation and facilitating the placement of other electrical components. This arrangement is characterized by a reasonable layout and convenient operation.

[0048] In this solution, the air box 2 is provided with a hoisting structure so that the assembled air box 2 can be hoisted to a suitable position and then assembled and connected with the cabinet 14. Figure 9 and Figure 10 shown.

[0049] Specifically, the hanging structure includes: two hanging plates 5, the structure of which can refer to Figure 4 As shown;

[0050] Two lifting plates 5 are located on the left and right sides of the top of the air box 2, each with a lifting hole. Specifically, the air box 2 is lifted to the desired location using the lifting holes of the lifting plates 5, then lowered vertically to the top of the cabinet 14 for assembly and connection. The corresponding mounting holes on the two plates are connected via bolts. Of course, other lifting structures, such as lifting rings and lugs, can also be used in this solution, and these will not be discussed here.

[0051] In addition, if Figure 12 As shown, the ring network switch cabinet of this solution needs to fully consider the interface size when designing, reserve the positions of connection holes and wire holes, and also make a unified design for the external dimensions to ensure product consistency and improve the versatility of components.

[0052] In summary, the ring network switch cabinet provided by the embodiment of the present invention fully utilizes the overall space of the cabinet body, rationally arranges and configures two sets of switch mechanisms, forms a new ring network switch cabinet, fills the gap in ring network switch cabinets, improves the scope of product application, facilitates on-site installation and subsequent maintenance, and improves product versatility. In addition, it has a simple structure, high versatility of parts, high space utilization, a wide range of product applications, and a high degree of standardization, which can meet the requirements of different customer solutions. The product has good consistency, simple assembly and high production efficiency, high material utilization, low production cost, and less resource waste. In other words, the ring network switch cabinet provided by the embodiment of the present invention, by forming two sets of switch mechanisms, can meet the needs of matching different combination solutions of customers, improve the internal space utilization of the ring network switch cabinet, and reduce the land area occupied by the cabinet body; it can also effectively save production and manufacturing costs, reduce use and maintenance costs, and bring considerable economic benefits; at the same time, it can realize the temporary power supply function to meet the temporary power demand of users and is suitable for temporary power supply scenarios.
