YB-12/0.4 box-type substation, also known as pre-installed substation or pre-installed substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme. It is a combination of transformer voltage reduction, low-voltage distribution and other functions, and is installed in a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulating, fully enclosed and movable steel structure box, especially suitable for urban network construction and renovation, it is a brand-new substation rising after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil power distribution room and power distribution station and becomes a new complete set of power distribution equipment.

Application Prospect Editor

Box-type substation is the main direction of the current rural power grid transformation and future substation construction, but there are still some shortcomings in some aspects, as shown in:

(1) Fire prevention: Box-type substations are generally fully sealed and unattended. Although all equipment operates without oil and is equipped with a remote smoke alarm system, there are still fire hazards in the box, such as cables, compensation capacitors, etc. Once a fire breaks out, it is not conducive to ventilation and fire fighting. Therefore, the design of automatic fire extinguishing system should be considered, but this will increase the manufacturing cost of box-type substations.

(2) Expansion problem: Due to the limitation of volume and manufacturing cost, the expansion margin of outgoing line interval is small. If it is difficult to add 1~2 outgoing line interval to the original box, it is necessary to add another box to do so.

(3) maintenance problems: due to the box-type substation in the manufacture of manufacturing costs and box volume constraints, so that the box-type substation maintenance space is small, not conducive to equipment maintenance, especially accident repair, this is the box-type substation congenital deficiencies, is unable to overcome the shortcomings.

In short, looking forward to the future, box-type substation in China's vast cities, rural areas, industrial and mining enterprises, public building facilities will be widely used, it will be used by more and more people with its advantages of high quality and low price, so that China's power grid operation level to a new level.
