Prefabricated modular substation usually adopts the mode of “whole station” equipment prefabrication, i.e. high-voltage switching and distribution device, transformer, medium-voltage switching and distribution device, compensation device, comprehensive automation system, AC and DC power supply system, environmental control system and cabin for integrated design, all the station equipment prefabrication and installation in the factory is completed, and after commissioning, the modules are transported to the site for docking, installation and commissioning to be put into operation. All station equipments are prefabricated and installed in the factory, and after being qualified, they are transported to the site in modules for docking, installation and commissioning to be put into operation.
Jiangsu Yawei Transformer has the technical ability to provide “whole station” construction solutions, including: substation design, equipment procurement, construction of the corresponding facilities and equipment installation, system intermodulation, the substation into operation, and then the entire substation handed over to the user as a whole, so as to achieve the modularity of the substation function, the standardization of the construction of the station, Turnkey” project with modularized substation functions, standardized station construction and intelligent system.
Prefabricated modular substations give full play to the significant advantages of improving construction efficiency, saving building area, saving operation and maintenance costs, reducing energy consumption, reducing pollution, etc., and are widely used in the fields of electric power, petroleum, chemical industry, shipbuilding, communications, civil construction and railroad construction. At the same time, with the maturity and development of the station power equipment technology, substation equipment will tend to become more and more miniaturized and highly reliable, which will further enhance the reliability and applicability of prefabricated modular substations, and will have a broad application prospect in the field of new infrastructure.
Advantages of prefabricated cabin substations
First, saving land resources. Due to the installation mode of integrated design of the cabin and construction, the overall footprint of the prefabricated cabin is more compact, which largely saves the occupied land area, and compared with the traditional type of substation, its space occupancy rate is significantly reduced.
Second, the layout of prefabricated cabin-type substation is more flexible, according to the differences in the construction area of three-dimensional construction of the station, the reasonable distribution and layout of the various panels, so as to meet the construction needs of prefabricated cabin-type substation.
Thirdly, the emergence of prefabricated cabin technology has optimized the traditional process flow, improved the way facilities are installed and tested, and reduced the volume of work, thereby reducing the construction period and further ensuring that the project is delivered within the specified time.
