Description

Technical Field

[0001] This utility model belongs to the technical field of GIS combined electrical appliances accessories, and specifically relates to a cable tray structure for GIS combined electrical appliances. Background Technology

[0002] GIS switchgear is currently widely used in power equipment systems. To achieve the control and interlocking of each unit module of the switchgear product, electrical wiring is required. The routing and layout of secondary cables become a key process control point, which directly affects the convenience of equipment maintenance and the overall aesthetics of the GIS.

[0003] Currently, most GIS manufacturers use metal flexible conduit to connect the secondary cables to the cable trays. The secondary cables are laid inside the trays, and after the cable routing and wiring are completed, the tray body and cover are connected using rivets. However, this method has several drawbacks: rivet connections have relatively poor strength, requiring multiple rivet holes on both the tray body and cover, leading to a significant workload during cover installation; additionally, rivets may scratch the secondary cables during cover installation, posing a quality risk; furthermore, the cover is extremely difficult to disassemble for later maintenance and rewiring, causing considerable inconvenience.

[0004] When designing cable trays, GIS manufacturers face challenges due to varying project configurations, requiring individual designs for each location. This results in a wide variety of cable tray types and a higher risk of design errors. Furthermore, the lack of standardization in cable tray design makes production organization difficult, increasing processing time and ultimately impacting the overall GIS production and assembly schedule. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a cable tray structure for GIS combined electrical appliances.

[0006] This utility model is achieved through the following technical solution:

[0007] A cable tray structure for GIS combined electrical appliances includes a cable tray body, characterized in that: a cable tray cover plate is provided on the cable tray body, the cable tray body and the cable tray cover plate are connected and fixed by several pairs of fasteners, several small knock-out holes are provided on the side of the cable tray body, and several large knock-out holes are provided on the cable tray cover plate.

[0008] The buckles are in three pairs, located at both ends and the middle of the cable tray body and the cable tray cover plate, respectively.

[0009] The beneficial effects of this utility model are: the connection between the cable tray body and the cover plate adopts a snap-on form, and the snap-on is installed with pre-set holes, eliminating the need for manual drilling and greatly reducing the amount of installation work in the factory and on-site. The cable tray body and cover plate are equipped with knock-out holes, so one type of cable tray can be used in multiple locations, reducing design errors and facilitating production organization. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Appendix Figure 1 This is a schematic diagram of the main structure of this utility model;

[0012] Appendix Figure 2 This is a side view of the structure of this utility model;

[0013] In the diagram, 1 is the cable tray body, 2 is the cable tray cover, 3 is the buckle, 4 is the small knock-out hole, and 5 is the large knock-out hole. Detailed Implementation

[0014] The attached figure shows a specific embodiment of this utility model. This embodiment includes a cable tray body 1, with a cable tray cover plate 2 mounted on the cable tray body 1. The cable tray body 1 and the cable tray cover plate 2 are connected and fixed by several pairs of fasteners 3. The side of the cable tray body 1 has several small knock-out holes 4, and the cable tray cover plate 2 has several large knock-out holes 5. There are three pairs of fasteners 3, located at both ends and the middle of the cable tray body 1 and the cable tray cover plate 2, respectively.

[0015] Using the cable tray structure of this utility model for GIS combined electrical appliances, after the installation of each standard unit module of the GIS body is completed, the secondary wiring work begins. The cable tray body 1 is installed, and the secondary cables are laid in the base frame and the cable tray body 1. According to the specific cable outlet positions of the mechanism box, terminal box, and junction box, the appropriate cable tray knock-out holes are selected and knocked out. Metal flexible tubing and metal connectors are used to connect to the cable tray to complete the secondary wiring. The cable tray cover plate 2 is installed to the cable tray body 1 through the buckle 3. When the secondary wiring is changed or secondary cables are added in the future, the cable tray cover plate 2 can be opened through the buckle 3 for easy disassembly.

[0016] The design drawings for the cable tray body 1 and cable tray cover 2 include the design of the buckle mounting holes. The number and arrangement of the buckle holes take into account the actual length of the cable tray. After the cable tray body 1 and cable tray cover 2 are processed, the assembly personnel will fix and install the buckles 3. After the cable tray body 1 is in place and the secondary cable wiring is completed, the cable tray cover 2 is fixedly connected using the buckles 3. If there is an error in the secondary wiring, the cable tray cover 2 can be opened simply by using the buckles 3.

[0017] The connection between the cable tray body 1 and the cable tray cover plate 2 is achieved using a latch 3. A latch 3 of suitable size is selected, and mounting holes are designed at appropriate locations within the cable tray. The latch 3 facilitates the installation and removal of the cable tray body 1 and the cable tray cover plate 2. The cable tray drawings are standardized to suit different application scenarios, optimizing the types of cable trays and incorporating knock-out holes. Assembly personnel in the workshop can then select the appropriate type based on actual needs.

[0018] The cable tray design accommodates small knock-out holes 4 and large knock-out holes 5 for different applications, reducing the variety of cable tray designs. During actual use, assemblers can selectively knock out the appropriate holes according to the specific installation location for connecting metal flexible hoses and secondary wiring.

[0019] The cable tray structure for GIS combined electrical appliances, as described in this utility model, features a simple structure, reliable performance, and improved workshop production and assembly efficiency, greatly facilitating subsequent inspection and maintenance. Furthermore, the pre-fabricated knockout holes simplify workshop production organization and reduce the procurement cycle for spare parts.
