[0020] The features and performances of the utility model are further described in detail in combination with the embodiments.

[0021] The utility model aims at providing a kind of GIS with closed wire slot assembly, to solve the problem that the main transition wiring piece of the wiring assembly of existing GIS cannot adapt to the GIS of control cabinet suspension type arrangement.

[0022] As a kind of basic scheme, as Figure 1As shown, the GIS with the closed wire duct assembly includes a circuit breaker cylinder 1, a circuit breaker mechanism box 2, a grounding switch 3, a grounding switch mechanism box 4, a current transformer 5, a control cabinet 6 and a closed wire duct assembly. The closed wire duct assembly includes a main wire duct 7 and a branch wire duct 8. The main wire duct 7 is the main part of the entire closed wire duct assembly. The main wire duct 7 is used to accommodate and transmit a large number of wires and cables, and provides necessary power and control signals for the GIS and the control cabinet 6. The main wire duct 7 is connected to the control cabinet 6 wire duct. The cables in the main wire duct 7 are introduced into the control cabinet 6 through the control cabinet wire duct 9. The control cabinet wire duct 9 receives the cables from the main wire duct 7 and introduces them into the control cabinet 6. The control cabinet wire duct 9 is the interface between the control cabinet 6 and the main wire duct 7, which ensures that the power and control signals can smoothly enter the control cabinet 6. The floor wire duct 10 connects the control cabinet 6 and the power station ground main cable trench, and transmits the cables between the control cabinet 6 and the external power station main cable trench. The interface between the control cabinet wire duct 9 and the main wire duct 7 is usually designed to be standardized, such as a flange, a buckle, etc., so as to quickly and accurately connect the two. The GIS with the closed wire duct assembly of the utility model realizes effective management and protection of the wires and cables through reasonable layout and design, and improves the safety and reliability of the GIS and the control cabinet 6. The modular design of the closed wire duct assembly makes it more convenient and fast to maintain and replace the cables. The compact design of the closed wire duct assembly improves the space utilization, which is beneficial to reduce the occupied area and reduce the cost.

[0023] As a preferred embodiment, as shown in Figure 3 As shown, the floor wire duct 10 is arranged on the side of the control cabinet 6. By arranging the floor wire duct 10 on the side of the control cabinet 6, the cable crossing and confusion can be minimized, the smooth flow of the cables and the overall beauty of the system are ensured, the influence of the main wire duct 7 on the introduction of the cables into the control cabinet 6 through the control cabinet wire duct 9 is avoided, and the overall efficiency and reliability of the wire duct system are improved. The floor wire duct 10 is arranged along the side of the control cabinet 6, which ensures that the cables can directly enter the control cabinet 6 from the main cable trench through the floor wire duct 10. In other optional embodiments, the floor wire duct 10 can also be arranged on the back of the control cabinet 6, as shown in Figure 2 As shown, one end of the main wire duct 7 is arranged on the back of the control cabinet 6, and enters the control cabinet wire duct 9 through the back of the control cabinet 6. When the floor wire duct 10 is arranged on the back of the control cabinet 6, attention should be paid to avoid the main wire duct 7 and the control cabinet wire duct 9.

[0024] As a preferred embodiment, the control cabinet wire slot 9 is arranged at the bottom of the control cabinet 6, which ensures the smooth transition of the cable from the main row wire slot 7 to the inside of the control cabinet 6, avoids interference with other components of the control cabinet 6, and helps to improve the overall reliability and maintainability of the GIS system. The bottom of the control cabinet 6 is usually designed with openings for installing the wire slot of the control cabinet 6, and the position and size of these openings can be set according to actual needs to ensure that the cable can enter smoothly.

[0025] As a preferred embodiment, the cable should be arranged in order in the main row wire slot 7 and the control cabinet wire slot 9, avoiding confusion and entanglement, and setting the main row wire slot 7 and the control cabinet wire slot 9 that leads the cable into the control cabinet 6 at the same height, which facilitates the arrangement and fixation of the cable and reduces the risk of movement and damage of the cable. The main row wire slot 7 and the control cabinet wire slot 9 are at the same height, which allows the cable to transition from the main row wire slot 7 to the control cabinet 6 more directly and compactly, reducing the bending and crossing of the cable and thus reducing the loss and failure rate of the cable. The same height of the main row wire slot 7 and the control cabinet wire slot 9 also facilitates the fixation and disassembly of the interface for later maintenance and troubleshooting to replace or repair the cable, saving maintenance time and cost. In other embodiments, the main row wire slot 7 and the control cabinet wire slot 9 are at different heights, and an interface needs to be added between the main row wire slot 7 and the control cabinet wire slot 9 to allow the cable in the main row wire slot 7 to enter the control cabinet wire slot 9.

[0026] As a preferred embodiment, the main row wire slot 7 is connected to the branch wire slot 8, which is used to connect the main row wire slot 7 with the breaker cylinder 1, the breaker mechanism box 2, the grounding switch 3, the grounding switch mechanism box 4, and the current transformer 5 of the GIS. The branch wire slot 8 installs and accommodates the cables of the breaker cylinder 1, the breaker mechanism box 2, the grounding switch 3, the grounding switch mechanism box 4, and the current transformer 5 of the GIS, ensuring accurate transmission of current signals, with one end connected to the main row wire slot 7 and the other end connected to the mechanism box and the current transformer 5 of the GIS; the cables from different elements are distributed in order to ensure that each cable can be accurately and orderly merged into the main row wire slot 7.

[0027] In a preferred embodiment, at least two branch cable trays 8 are connected to the main cable tray 7. Depending on the scale and component distribution of the GIS system, at least two branch cable trays 8 are provided. The branch cable trays 8 should be located as close as possible to the component distribution area to reduce cable length and crossings. The branch cable trays 8 systematically distribute cables from different components, ensuring that each cable accurately and orderly merges into the main cable tray 7. By setting multiple branch cable trays 8, cables can be managed more effectively, reducing cable crossings and clutter, improving cabling efficiency, and lowering the failure rate caused by improper cable management. The number of branch cable trays 8 can be flexibly adjusted according to the actual layout and component distribution of the GIS system, optimizing the cable layout to make it more compact and orderly, improving the overall aesthetics of the system, protecting cables from external interference, and enhancing the overall reliability and stability of the GIS.

[0028] In a preferred embodiment, the branch cable tray 8 is connected to the side wall of the main cable tray 7 along its extension direction. Placing the branch cable tray 8 on the side wall of the main cable tray 7 allows for more efficient use of space, simplifies the wiring process, and avoids excessive cable accumulation and crossing. This design makes the cable routing clearer, helps reduce wiring difficulty and improve wiring efficiency, and also enhances the overall aesthetics and neatness of the GIS. The side wall placement of the branch cable tray 8 also facilitates cable connection and management for staff, making it easier to identify and distinguish cables for different components and accurately connect them to the main cable tray 7. Clear cable layout and labeling make later maintenance and troubleshooting simpler and more efficient, allowing staff to more easily find and repair damaged cables or connection problems.

[0029] The specific implementation process of this embodiment is as follows: the cables of various GIS devices from the branch cable trays 8 are arranged in the main cable tray 7, and the cables are connected into the control cabinet 6 through the control cabinet cable tray 9 at the bottom of the control cabinet 6. The cables in the control cabinet 6 are finally connected into the main cable trench through the ground cable tray 10.
