YB -40.5 prefabricated cabin substation
Overview of development status
Prefabricated cabin-type combined equipment was studied and applied abroad at an early time. In the mid-1980s, it was applied to the overall modular 33kV substation in the United States; in the 1990s, the overall modular 66kV substation in Japan also applied prefabricated equipment cabins. The container-type electrical hut launched by ABB has been widely used in the Middle East countries.
In China, 35kV and 10kV box-type substations have been widely used in projects, and containerized SVG equipment, containerized DC ice melting equipment, and containerized photovoltaic inverters are also widely used.
In 2013, State Grid Corporation of China launched the construction of a new generation of intelligent substation demonstration project, and proposed the construction principles of "standardized design, factory processing, modular construction, and mechanized construction".
According to this principle, in the new generation of smart substations, there are almost no buildings, instead there are prefabricated cabin-type combined equipment.
In the State Grid Corporation's new generation of intelligent substation demonstration project, Chongqing Dashi 220kV substation and Hubei Future City 110kV substation are AIS substations, both of which use prefabricated cabin-type combined equipment.
The construction of the new generation of intelligent substations has accumulated valuable experience in the application of prefabricated cabin-type combined equipment, and actively guided domestic equipment manufacturing companies to carry out equipment research and technological innovation. Our company is a professional manufacturer that designs and produces special containers (functional rooms, electrical equipment boxes, water treatment equipment boxes and other equipment boxes), container mobile houses (camping houses, dormitories, office rooms), ordinary land transport containers (standard containers and non-standard containers), wing boxes and color steel plate houses, and sells accessories for containers, curtain boxes and wing boxes.
Selection principles
(1) The appearance design is beautiful and coordinated with the external environment. For example, the appearance of the container should be as simple as possible, the size and position of the air conditioner, inlet and other parts should be reasonably designed, and the color of the container should be coordinated with the surrounding transformers and high-voltage switchgear.
(2) The selection of cabin box size should take into account the equipment transportation requirements, plane layout requirements and transportation requirements.
(3) Reduce external wiring of prefabricated cabins and design a unified interface.
(4) The screen layout is reasonable and the space for operation and maintenance channels is expanded as much as possible.
(5) Engineering installation and commissioning to reduce on-site workload. The installation and wiring of equipment in the prefabricated cabin should be completed in the factory as much as possible, and only the connection between the prefabricated cabin and external equipment should be carried out on site.
Product Benefits
High reliability
The main components adopt the world's most advanced technology, which is safe and reliable, and the completely maintenance-free prefabricated cabin structure, combined with micro-positive pressure air conditioning, constant temperature and humidity, dust-free, surpassing the indoor operating environment.
Small footprint
The minimum equipment area is 340m2, and the minimum site area is 416m2.
Factory
All equipment installation and commissioning are carried out in the factory.
Fast website building
The website building cycle is 3~6 months.
Fast commissioning
The workload of on-site debugging is small, and the equipment can be put into operation 15 to 30 days after arrival.
Low noise
Use sound barrier technology to reduce transformer noise.
No radiation
Fully enclosed metal casing to reduce electromagnetic radiation.
High lifespan
The main components are completely maintenance-free, the cabin is rust-proof for 30 years, and the service life is 60 years.
Beautiful appearance
The integrated design concept of cabins and cabinets and the modular structure of building blocks are in harmony with the urban style.
Six No
No rooms, no walls, no structures, no radiation, no noise, and no one on duty.
Modularity
The building blocks have a modular structure and flexible layout.
Factory commissioning
Simulate on-site substation construction in the factory to verify the substation structural design and improve the efficiency of on-site substation construction.
The primary system joint debugging, secondary system joint debugging and overall joint debugging are completed in the factory.
Jointly conduct on-site acceptance with the customer’s acceptance department and the supervision unit.
Delivery transportation
The prefabricated cabin is transported and delivered as a whole, and hoisted as a whole, which is convenient and fast.
Prefabricated cabin modules can meet the over-limit requirements of external dimensions for road, rail and sea transportation.
Prefabricated construction
The building block construction mode minimizes the on-site construction workload.
The large cabin is constructed in modular sections in the factory and assembled in modular sections on site, which greatly shortens the construction period.
Abandoning the traditional on-site "wet method" construction, thus saving water resources and protecting the ecological environment.
The overall quality level and safe operation level of the project have been improved, and cost optimization, energy conservation and environmental protection have been achieved to the greatest extent.
