Prefabricated Cabin-Type Substation is a new mode of rapid construction, it is on the basis of the mature manufacturing technology of outdoor box type substation products, combined with the "standardized design, factory processing, prefabricated construction" requirements. The substation primary and secondary system equipment should be installed and debugged in the factory before put into a mobile, sealed, moisture-proof, rust-proof prefabricated cabin,to achieve the "four modernizations" power station construction, namely the system integration, production industrialization, assembly modularization and construction simplification. Besides in the power system,
Prefabricated Cabin-type Substation has been well popularized and applied in the petroleum industry、chemical industry, mining、smelting、
New Energy、offshore wind booster station、data center and other fields because of its fast speed, short construction period, small covering area, high land utilization rate, low construction quantity, high safety reliability, low construction and operating cost, sound insulation shielding effect, energy conservation and environmental protection.
Performance characteristics of prefabricated cabin-type substation:
(1) Small covering area. Adopt modular design, support double-layer three-dimensional layout, save the cost of land acquisition.
(2) Flexibility of station building. Requirement of the site is not high, and the layout can be flexible according to the actual situation of the site (land shape, geology, etc.). Remote reconstruction and movable.
(3) The site construction engineering quantity is reduced. For traditional station construction mode, large amount of civil engineering, assembly、wiring and commissioning after the transportation of equipment to the site, greatly affected by climate environment, long construction period; for prefabricated cabin mode, prefabricated installation、wiring and commissioning in the factory,only assembly at the site, indirect line, less affected by climate environment and short construction period.
(4) The complexity of the site construction management is reduced. For traditional station construction mode, civil construction foundation first, second equipment installation, and then distribution room construction. Engineering cycle is long, cross operation and management is difficult; For prefabricated cabin mode, only the simple foundation construction of the prefabricated cabin need to be done at the site and the civil construction can be withdrawn after the completion, and wait the prefabricated cabin being finally in place, which can avoid cross construction and the construction management is relatively simple.
(5) Good environmental protection. For the traditional station construction mode with wet process, large civil construction quantities, much dusty and heavy dust pollution to the environment and great impact on the surrounding environment; for the prefabricated cabin mode, less civil construction quantities, little impact on the surrounding environment and good environmental protection.
(6) Exquisite in appearance and in harmony with the environment. According to the surrounding environment of the booster station, the prefabricated cabin mode is customized appearance painting, which is in harmony with the environment. At the same time, the prefabricated cabin-type substation has a good isolation of electromagnetic radiation and noise reduction function and it's easy to be accepted by the surrounding residents.
(7) The construction period is short. The construction period of the prefabricated cabin-type substation is short, the foundation construction and the production of the prefabricated cabin are synchronized and the construction period is about 3 months.
(8) Low comprehensive cost. The traditional station construction mode is relatively fixed and the cost optimization space is limited; for the prefabricated cabin-type station, the civil construction and installation costs can be reduced, the construction period shortened, power generation connected to the grid advanced, revenue advanced and the comprehensive cost reduced by about 10%.
