Description

Technical Field

[0001] This utility model relates to the field of electrical equipment accessories technology, and in particular to an indoor top cable tray for an integrated substation unit. Background Technology

[0002] In the electrical assembly of substation integrated units, cable trays are key components used to organize and protect primary and secondary cables. Their reasonable design directly affects the safety, ease of maintenance, and space utilization of the equipment.

[0003] Currently, primary and secondary cables in transformer substations are mostly laid at the bottom, resulting in poor rodent and moisture protection. Furthermore, separate laying of primary and secondary cables increases the number of cable trays, occupying limited internal space and complicating installation and maintenance. Additionally, existing cable trays often use snap-fit ​​connections between the tray body and cover. When installed on top of the transformer, the cover, bearing the weight of the cables, is prone to detaching from the tray body, posing a safety hazard of falling from height. This is especially problematic when cables are heavy or numerous, making cable laying difficult for a single person and reducing installation efficiency.

[0004] Therefore, there is an urgent need for a cable tray structure that can integrate primary and secondary cable laying and is easy to install, in order to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an indoor top cable tray for an integrated substation unit, thereby solving the problems mentioned in the background art.

[0006] To achieve the above technical objectives, the present invention provides a substation integrated machine indoor top cable tray, comprising: a tray bottom and a tray cover, wherein the tray bottom is provided with a plurality of mounting holes, the sides of the tray bottom and the tray cover are folded and interlocked with each other, a hanging plate and a plurality of connecting strips are provided between the tray bottom and the tray cover, the plurality of connecting strips are equidistantly arrayed along the length direction of the tray bottom and fixedly connected to its inner wall, the sides of the hanging plate are interlocked with the connecting strips, and a plurality of arc-shaped strips are provided on both sides of the hanging plate, the two ends of the arc-shaped strips being fixedly connected to the hanging plate.

[0007] Furthermore, the hanging plate is composed of several connecting square tubes and supporting square tubes of equal width connected end to end. The width of the connecting square tubes and supporting square tubes is less than or equal to the inner distance between the bottom of the groove and the top of the groove. The outer width of the connecting square tube is equal to the inner width of the supporting square tube. The arc-shaped strip is set on the connecting square tube. Several connecting holes are provided on the supporting square tube. The horizontal and vertical spacing of the connecting holes is equal to the horizontal and vertical spacing of the arc-shaped strip. The width of the connecting holes is equal to the width of the arc-shaped strip.

[0008] Furthermore, the two width directions and one length direction of the connecting strip are folded and fixedly connected to the bottom of the groove. The connecting strip is provided with a plurality of connecting grooves, which are equidistantly arranged along the length direction of the connecting strip. The side of the hanging plate is provided with a plurality of locking posts that cooperate with the connecting grooves, which are equidistantly arranged along the length direction of the hanging plate. The distance between two adjacent locking posts is equal to the distance between two adjacent connecting strips.

[0009] Furthermore, the outer side of the folded edge of the groove bottom is provided with a slot along its length, the inner side of the folded edge of the groove cover is provided with a locking strip that cooperates with the slot, and the folded edge of the groove cover is provided with heat dissipation holes.

[0010] Furthermore, ventilation holes are provided on both sides of the connecting square tube, and the two ends of the arc-shaped strip are fixedly connected to the two ends of the ventilation holes.

[0011] Compared with the prior art, the beneficial effects of this utility model include: 1. This utility model uses a hanging plate and connecting strip between the bottom of the trough and the trough cover. The hanging plate consists of a connecting square tube and a supporting square tube. The connecting square tube can be inserted into the supporting square tube to adjust the length of the hanging plate. The hanging plate can divide the space enclosed by the bottom of the trough and the trough cover into two parts, where primary and secondary cables are laid respectively. The laying space can be adjusted by changing the connecting groove into which the hanging plate clip is inserted, to adapt to different installation requirements. At the same time, the square tube of the hanging plate effectively isolates the primary and secondary cables, reduces the electromagnetic radiation influence of both, and ensures the stability and safety of cable operation.

[0012] 2. This utility model features ventilation holes and arc-shaped strips on the side of the connecting square tube, and connecting holes on the supporting square tube. Multiple hanging plates can be connected by the arc-shaped strips passing through the connecting holes. When installing cables, cable ties pass through the arc-shaped strips to fix the cables, preventing the cable weight from being entirely borne by the trough cover and reducing the risk of the trough cover detaching from the trough bottom. In addition, the connecting holes, ventilation holes, and heat dissipation holes on the trough cover can dissipate the heat generated by the cables inside the trough in a timely manner, preventing heat accumulation from affecting cable performance and ensuring the overall safe operation of the equipment.

Detailed Implementation

[0014] 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 only used to explain this utility model and are not intended to limit this utility model.

[0015] This utility model provides an indoor top cable tray for an integrated substation unit, such as... Figure 1 As shown, the device includes a slot bottom 1 and a slot cover 2. The outer side of the folded edge of the slot bottom 1 is provided with a slot 102 along its length direction. The inner side of the folded edge of the slot cover 2 is provided with a locking strip 201 that cooperates with the slot 102. The slot bottom 1 and the slot cover 2 are quickly connected by the engagement of the slot 102 and the locking strip 201. The folded edge of the slot cover 2 is provided with heat dissipation holes 202, which are evenly distributed along the length direction of the slot cover 2. The slot bottom 1 is provided with several mounting holes 101. The entire cable tray can be fixed in a preset position on the top of the transformer room through the mounting holes 101. The mounting holes 101 are evenly distributed along the length direction of the slot bottom 1, and the spacing is usually set to 500mm to facilitate adjustment of the fixing points according to actual installation requirements.

[0016] A hanging plate 3 and several connecting strips 4 are provided between the bottom of the tank 1 and the cover of the tank 2. The connecting strips 4 are made of metal, and their two width directions and one length direction side edges are folded over and fixed to the inner wall of the bottom of the tank 1; see reference. Figure 2 , Figure 3 The connecting strip 4 is provided with several connecting grooves 401, which are equidistantly arranged along the length of the connecting strip 4. In common settings, the distance between two adjacent connecting grooves 401 is 100mm. The side of the mounting plate 3 is provided with several locking posts 306 that cooperate with the connecting grooves 401. The locking posts 306 are cylindrical structures with a limiting block at the top. The diameter of the locking posts 306 is adapted to the width of the connecting grooves 401. The locking posts 306 are equidistantly arranged along the length of the mounting plate 3. The distance between two adjacent locking posts 306 is equal to that between two adjacent connecting strips 4, ensuring that the mounting plate 3 can be stably locked onto the connecting strip 4. This divides the space enclosed by the groove bottom 1 and the groove cover 2 into two parts, which are used for laying primary and secondary cables (control and power) respectively. By changing the connecting grooves 401 into which the locking posts 306 of the mounting plate 3 are inserted, the laying space of the primary and secondary cables can be adjusted to adapt to different installation requirements.

[0017] Reference Figure 3 , Figure 4The hanging plate 3 is composed of several connecting square tubes 301 and supporting square tubes 302 of equal width connected end to end. In practical applications, both the connecting square tubes 301 and supporting square tubes 302 can be lightweight and high-strength metal square tubes. The outer width of the connecting square tube 301 is equal to the inner width of the supporting square tube 302. This arrangement allows the connecting square tube 301 to be inserted into the supporting square tube 302 during installation, forming an integral hanging plate 3 structure. At the same time, the width of the connecting square tube 301 and supporting square tube 302 is less than or equal to the inner distance between the bottom of the groove 1 and the cover of the groove 2, ensuring that the hanging plate 3 can be smoothly installed between the bottom of the groove 1 and the cover of the groove 2.

[0018] Ventilation holes 303 are provided on both sides of the connecting square tube 301. The ventilation holes 303 are rectangular holes and are distributed along the length of the connecting square tube 301. Several arc-shaped strips 304 are also provided on both sides of the connecting square tube 301. Their two ends are fixed to the two ends of the ventilation holes 303. The arc-shaped strips 304 protrude away from the connecting square tube 301. When installing cables, cable ties pass through the arc-shaped strips 304 to fix the cables to them. In the existing cable trays, the cables are directly laid in the cable tray. When the cable tray is installed on the top, the weight of the cables is entirely borne by the tray cover, which increases the risk of the tray cover detaching from the tray bottom and causing the cables to fall off. The technical solution of this application solves the above defects.

[0019] The supporting square tube 302 is provided with several connecting holes 305. The horizontal and vertical spacing of the connecting holes 305 is equal to the horizontal and vertical spacing of the arc-shaped strips 304, and the width of the connecting holes 305 is equal to the width of the arc-shaped strips 304. When it is necessary to adjust the length of the hanging plate 3, the connecting square tube 301 is inserted into the supporting square tube 302, and the arc-shaped strips 304 pass through the connecting holes 305 from the supporting square tube 302, thereby connecting multiple hanging plates 3. At the same time, the square tube of the hanging plate 3 effectively isolates the primary and secondary cables, reducing the influence of electromagnetic radiation from both. The connecting holes 305, vent holes 303, and heat dissipation holes 202 can dissipate the heat generated by the cables inside the cable tray in a timely manner, preventing heat accumulation from affecting cable performance.
