Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a semi-indoor substation cable laying system based on earthquake-resistant design. Background Art

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. The cables of substations are usually laid in cable trenches or cable shafts. The existing cable trenches and cable shafts are mostly made of bricks and have weak earthquake resistance. During an earthquake, cable trenches and cable shafts are prone to collapse, causing serious consequences such as short circuit fires and paralysis of secondary communication equipment. In addition, the cleanup work after the collapse of brick cable trenches and cable shafts is arduous, which is not conducive to rapid recovery after the disaster.

[0003] To this end, we design a semi-indoor substation cable laying system based on earthquake-resistant design. Utility Model Content

The indoor cable trench and the equipment foundation slab of the distribution device building are cast as one piece. Precast concrete conduits are laid at the outdoor primary cable location and the location where the outdoor secondary cable crosses the road. Precast ground grooves are laid at the remaining outdoor secondary cable locations. Steel wall cabinets are installed at the cable shaft location in the distribution device building.

[0006] Preferably, the prefabricated ground trench comprises a concrete trench, and a plurality of concrete support frames distributed at equal intervals are cast inside the concrete trench.

[0007] Preferably, the steel wall cabinet is composed of several vertically distributed wall cabinet units, and the wall cabinet unit includes a steel frame, the steel frame is in the shape of a rectangular parallelepiped, a first steel plate is fixedly installed on the back of the steel frame by screws, and a second steel plate is installed on the front and left and right sides of the steel frame by hinges.

The steel frames of two adjacent wall cabinet units are connected by nuts and bolts, and the second steel plate can be fixed to the steel frame by screws.

[0009] Compared with the existing technology, the present invention provides a semi-indoor substation cable laying system based on earthquake-resistant design, which has the following beneficial effects:

[0010] 1. This semi-indoor substation cable laying system, designed for earthquake resistance, integrates the indoor cable trench with the equipment foundation slab to enhance its structural strength, enabling it to more effectively withstand the impact of earthquake waves. Furthermore, this integrated casting simplifies the construction process and improves overall project quality.

[0011] 2. This semi-indoor substation cable laying system, designed with earthquake resistance in mind, uses prefabricated ground trenches to lay outdoor secondary cables. Compared to traditional brick-built cable trenches, this system offers better integrity, better earthquake resistance, and reduced risk of cable damage.

[0012] 3. This semi-indoor substation cable laying system, based on earthquake-resistant design, uses steel wall cabinets as cable shafts. It not only has excellent load-bearing capacity and earthquake-resistant performance, but also can effectively isolate the cables from the erosion of the external environment and extend the service life of the cables.
