Description

Technical Field

[0001] This utility model relates to the field of power equipment, and in particular to a cable trough. Background Technology

[0002] Cables are indispensable basic components in the construction of modern power, communication, automation, and information networks—all systems requiring energy transmission or information transfer. Their performance and quality directly affect the safety, reliability, efficiency, and service life of the entire system. Cable trays are commonly used structural components in complete sets of power distribution equipment, their main function being to protect cables from damage caused by the external environment. Cables are needed to connect independent compartments (such as high-voltage and low-voltage compartments) and electrical components within complete sets of equipment to meet communication and control functions, requiring cable trays for cable protection. Outdoor complete sets of equipment have higher requirements for the protection of cable trays. Improper cable tray design can easily lead to dust accumulation, water ingress, or small animals, which can reduce the insulation performance of the cables, cause short circuits, or damage to the insulation layer by animals, resulting in equipment failure. Utility Model Content

[0003] The technical problem to be solved by this utility model embodiment is to provide a cable trough that can effectively prevent dust accumulation, outdoor rain water ingress, and the entry of small animals, thereby effectively protecting the cable.

[0004] To solve the above-mentioned technical problems, this utility model provides a cable trough, including a cable trough module, a cable trough flange, and an interface sealing gasket. The cable trough module includes a cable trough, a cover plate, and a cover plate sealing gasket. The cable trough has openings at the front and rear, and the cover plate is sealed on the cable trough by the cover plate sealing gasket. There are multiple cable trough modules, which are connected end to end in sequence by cable trough flanges. The cable trough modules and the cable trough flanges are sealed by interface sealing gaskets.

[0005] Furthermore, cable supports are installed inside the cable tray.

[0006] Furthermore, a cable tray support is provided at the bottom of the cable tray.

[0007] Furthermore, drainage holes are provided at the bottom of the cable tray.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0028] This invention can be directly applied to different independent compartments in a prefabricated substation. Please refer to... Figures 1-4 A prefabricated substation includes a prefabricated base and high-voltage and low-voltage rooms located on the prefabricated base.

[0029] Please refer to Figures 1-12 The cable trough of this utility model embodiment includes a cable trough module, a cable trough flange, and an interface sealing gasket. Screw holes are provided on the cable trough flange.

[0030] The cable tray module includes a cable tray, a cover plate, and a cover plate sealing gasket. The cable tray has openings at the front and back. The cover plate is sealed to the cable tray by the cover plate sealing gasket; that is, a cover plate sealing gasket is placed between the upper part of the cable tray and the cover plate, and the cover plate presses against the cover plate sealing gasket, and is fixed to the cable tray with bolts. The cable tray has a U-shaped cross-section. The cable tray and cover plate can be formed by cutting, bending, and welding thin steel plates. A cover plate sealing gasket is placed at the joint between the cable tray cover plate and the cable tray to prevent gaps from easily forming in the physical connection, effectively preventing dust and water. The cover plate is sealed in sections to avoid problems with the installation and maintenance of large components. In specific implementations, the cover plate can be equipped with reinforcing ribs to improve the overall strength of the cable tray module.

[0031] There may be one or more cable tray modules. When there is one, each end of a single cable tray module is connected to different independent compartments (e.g., a high-pressure compartment and a low-pressure compartment) via a cable tray flange, and the independent compartments are sealed to the cable tray flanges via interface gaskets. When there are multiple cable tray modules (the number depends on the distance between two independent compartments) are connected end-to-end via cable tray flanges, and the cable tray modules are sealed to the cable tray flanges via interface gaskets. The front end of the first cable tray module and the rear end of the last cable tray module are each connected to different independent compartments (e.g., a high-pressure compartment and a low-pressure compartment) via cable tray flanges, and the independent compartments are sealed to the cable tray flanges via interface gaskets. This invention uses identical cable tray flanges at appropriate locations between two independent compartments where cable trays are installed. The form of the cable tray flanges is standardized; please refer to [reference needed]. Figure 3 and Figure 4 This utility model can be divided into several sections for splicing according to the length of the entire cable tray. The size and interface of the splicing sections are standardized to facilitate rapid splicing of multiple sections. Interface sealing gaskets are installed between the cable tray modules to prevent gaps from easily forming in the physical connection, effectively preventing dust and water damage.

[0032] As one implementation method, a cable support is provided inside the cable tray. The height of the cable support is higher than the horizontal plane of the lowest point of the interface to prevent the cable from being submerged in water when liquid accumulates inside the cable tray.

[0033] As one implementation method, a cable tray support is provided at the bottom of the cable tray. The cable tray support raises the overall height of the cable tray, preventing moisture and water immersion.

[0034] As one implementation method, drainage holes are provided at the bottom of the cable tray. These drainage holes are preferably located near the interface to effectively guide rainwater or accumulated liquid flowing down the gaps between the cover plates.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
