Yb-12/0.4 (F. R.) Outdoor Pre-Installed Substation
Widely used in urban power grid renovation, residential communities, high-rise buildings, industrial and mining areas, hotels, shopping malls, airports, railways, oil fields, docks, highways, as well as temporary power facilities and other indoor and outdoor places.
1, Definition and Characteristics
Prefabricated substation is a factory prefabricated and integrated design power supply solution. It organically combines functions such as transformer voltage reduction and low-voltage distribution, and is installed in a moisture-proof, rust proof, dust-proof, rodent proof, fireproof, anti-theft, heat-insulating, fully enclosed, and movable steel structure box. This design not only improves the reliability and stability of the equipment, but also greatly simplifies the installation process and reduces maintenance costs.
2, Types and classifications
Prefabricated substations can be classified according to different standards:
Divided by overall structure:
European style change: High voltage switchgear, distribution transformers, and low voltage distribution equipment are arranged in three adjacent compartments and electrically connected through cables or busbars.
American style variation (pre installed substation): Place the transformer body, high-voltage load switch, fuse, and high and low voltage connections in a common packaging oil tank.
Divided by installation location: divided into indoor and outdoor types to meet different environmental requirements.
Divided by high-voltage wiring methods, including dual power supply wiring and ring network wiring, to meet different power supply reliability requirements.
According to the structure of the box, it can be divided into integral and split types to meet different installation space and layout requirements.
3, Advantages and Applications
Prefabricated substations have significant advantages over traditional substations and are widely used in multiple fields:
Highly automated: adopting intelligent design, the protection system adopts a microcomputer integrated automation device to achieve the "four remote" functions of telemetry, remote signaling, remote control, and remote adjustment.
Factory prefabrication: The equipment is installed and debugged in the factory and directly used on site, greatly shortening the project implementation cycle.
Safe and reliable: The box is made of high-strength materials and has good anti-corrosion, fireproof, and anti-theft properties. The operation of internal equipment is not affected by external factors and can adapt to various harsh environments.
Flexible combination: The structure is compact, with each box forming an independent system. The combination is flexible and versatile, and can be configured according to actual needs.
Low cost: Compared with conventional substations of the same scale, the cost is reduced by 40% to 50%, and the footprint is only 1/10 of that of substations of the same scale.
