Description

A cable interlayer for substation

technical field

The utility model relates to the technical field of substations, in particular to a cable interlayer used in substations.

Background technique

In the new period when the construction of the national grid is advancing by leaps and bounds, many substations that have been in operation for many years have undergone the process of capacity expansion, expansion and transformation, which makes the cable laying that was originally ruled by rules complicated and narrow, which not only affects the appearance, but also Daily operation and maintenance and troubleshooting bring inconvenience. Once a fire breaks out, the smoke will fill the air, making it difficult for firefighters to find the ignition point and put out the fire. The substation cable interlayer is the main place for installing, placing and fixing power cables and secondary control cables. Almost all the power and control box signals in the substation are transported by the cables laid on it. Therefore, a substation cable interlayer with good grounding, firmness and reliability, strong corrosion resistance, and complete fire protection system is a necessary condition to ensure the normal operation of the power system. .

Utility model content

The technical problem to be solved by the utility model is to provide a simple structure, firm and reliable cable interlayer for substations.

In order to solve the problems of the technologies described above, the technical scheme adopted by the utility model is as follows:

A cable interlayer for substations, characterized in that it includes a hollow bracket and a cable clamping mechanism, and the cable clamping mechanism is installed in the hollow bracket; the hollow bracket is composed of an upper frame and a lower frame, and the upper frame and the lower frame Connected by several vertical rods, the cable clamping mechanism is composed of a column and at least two crossbeams, and the crossbeams are vertically intersected with the columns.

Further, the upper frame and the lower frame are both composed of four square tubes, and the upper frame and the lower frame are also provided with several longitudinal bars and horizontal bars, and the longitudinal bars and the horizontal bars are arranged crosswise.

Further, the upper and lower ends of the column on the cable clamping mechanism are provided with connection blocks, and the cable clamping mechanism is connected to the hollow support through the connection block, which is more stable than the column directly welded on the hollow support. The connection block, The columns and beams are made of steel material, which is not easy to corrode, so that the clamping mechanism is not easy to fall off from the hollow bracket due to rust.

Further, there are several cable clamping mechanisms, and the gaps between each cable clamping mechanism are set. The cable clamping mechanisms are arranged in an orderly manner with reasonable spacing, which can enhance the safety of fire prevention and fire protection in the interlayer.

Further, the upper end, the lower end, and the side of the hollow bracket are all equipped with protective plates, and according to the wiring and guidance of the cables during use, wire inlets and outlets can be provided on the protective plates.

Further, the beam in the cable clamping mechanism is in the shape of "┍", which is convenient for installation, saves materials and has strong support.

Further, there are three beams in the cable clamping mechanism.

Compared with the prior art, the utility model has the following beneficial effects: simple structure, firm and reliable, high strength, low cost, can effectively save production time and improve equipment efficiency; each cable clamping mechanism is arranged in an orderly manner, the distance is reasonable, and the fire protection system is perfect The cable interlayer provides the necessary conditions for the normal operation of the power system.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

detailed description

As shown in Figures 1-3, the preferred embodiment of the utility model is used for the substation cable interlayer, including a hollow support 1 and several cable clamping mechanisms 2; the hollow support 1 is composed of an upper frame 11 and a lower frame 12, and the upper The frame 11 and the lower frame 12 are connected by several vertical rods 13. The cable clamping mechanism 2 is composed of a column 21 and three "┍"-shaped beams 22. The beams 22 and the columns 21 are vertically intersected. The upper and lower ends of the column 21 on the clamping mechanism 2 are provided with connecting blocks 23, the cable clamping mechanism 2 is connected with the hollow support 1 through the connecting block 23, and the connecting block 23 at the upper end of the column 21 is installed on the longitudinal bar 14 or the horizontal bar 15. If the lower frame 12 does not need to be provided with longitudinal bars 14 or cross bars 15, the connecting block 23 at the lower end of the column 21 can be placed on the ground as a pad for the column 21; Enhance the safety of fire prevention and fire protection in the interlayer.

Both the upper frame 11 and the lower frame 12 are composed of four square tubes, and the upper frame 11 and the lower frame 12 are also provided with a plurality of longitudinal bars 14 and cross bars 15, and the longitudinal bars 14 and the cross bars 15 are intersected.

The upper end, the lower end, and the side of the hollow support 1 are provided with a protective plate 3, which can be provided with an inlet and an outlet on the protective plate 3 according to the cable wiring and guidance during use.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model; that is, all equivalent transformations done according to the scope of claims of the present utility model are within the scope of claims of the present utility model covered by.
