What is the role of the box of the substation
Mar 21, 2022
Box type substation, also known as preinstalled substation or preinstalled substation. Is a kind of high voltage switch equipment, distribution transformers and low voltage power distribution equipment, according to the wiring scheme must be arranged in one of the factory indoor, outdoor compact type distribution equipment, the step-down transformer, low voltage power distribution, and other functions organically combined together, installed in a moisture, rust, dust, rat, fire prevention, guard against theft, heat insulation, fully enclosed, movable steel box, Especially suitable for urban network construction and transformation, it is a new substation after the rise of civil substation.
Box substation is a complete set of power distribution equipment which combines medium voltage switchgear, transformer and low voltage distribution equipment according to a certain wiring scheme. Compared with conventional civil engineering substation, box transformer has the advantages of small footprint, less on-site installation work, short installation cycle, free movement, reduced line loss, less investment and so on.
The main function of the box substation is a container, which houses medium voltage switchgear, transformers and low voltage distribution equipment. It is mainly composed of base, side plate, partition door and top cover.
The box is divided into high voltage chamber, transformer chamber and low voltage chamber. The coaming plates, partitions, doors and top covers above the base are connected by welding or fasteners. The base and top skeleton are generally welded with Angle steel or channel steel. Some of the boxes are covered with specially fire-resistant wooden boards to make them more compatible with modern buildings. The design of the box is very important because it is the skeleton of the substation. Therefore, we have to take into consideration in the design, where to add ventilation, where to add fans, where to add mounting beams, where to add fixed brackets and so on.
