Description

Technical field [0001] The invention relates to the integrated construction technology of substations, in particular to a pre-installed intelligent traction substation. Background technique [0002] The traditional traction substation is mainly composed of high-voltage switch, main transformer equipment, low-voltage side primary equipment, low-voltage side secondary equipment, and uses products from different manufacturers, which brings great inconvenience to system integration. The substation does not adopt an integrated method to handle the low-voltage side primary equipment and the low-voltage side secondary equipment. The wiring between the equipment is complicated, signal transmission interference occurs from time to time, and the construction period of the entire substation is long. It needs to go through several stages, equipment procurement stage, system connection In the design stage, the system debugging stage, especially the incompatibility between the equipment, the d...

Problems solved by technology

[0002] Traditional traction substations are mainly composed of high-voltage switches, main transformer equipment, primary equipment on the low-voltage side, and secondary equipment on the low-voltage side, and products from different manufacturers are used, which brings great inconvenience to system integration. The substation does not adopt an integrated method to deal with the low-voltage side primary equipment and the low-voltage side secondary equipment. The connection between the equipment is complicated, and signal transmission interference occurs from time to time. Moreover, the construction period of the entire substation is long, and it needs to go through several stages, the equipment procurement stage, the system connection In the design phase, system debugging phase, especially the incompatibility between equipments, the difficulty of debugging increases, therefore, the construction period of the entire substation is extremely long

[0003] In order to solve the problems of long construction period, large floor area and inconsistent process installation standards of traditional substations, we need to design a substation with standardized design, factory processing, and assembly construction to realize the miniaturization of substations and greatly improve the efficiency of engineering construction and quality, effectively reducing the life cycle cost
