Box-type Substation
Model: Photovoltaic(wind)power generation box substation
Application:
Photovoltaic(wind)booster box substation is a product specially designed and developed by our company for new energy power generation. The pre-installed substation is a complete set of substation products which reasonably combines auxiliary equipment such as step-up transformer, high-voltage switchgear, low-voltage switchgear and power transformer with the box. Its performance fully conforms to GB17467-
2010 High-voltage/Low-voltage Pre-installed Substation is a new type of pre-installed substation developed for the special use requirements of new energy power generation. It has the advantages of strong integrity, convenient installation, short construction period, low operating cost, high structural strength and strong anti-corrosion performance, and is completely suitable for operating environments such as beaches, grasslands and deserts with harsh natural conditions. The product has passed the type test of Shanghai Electric Power Transmission and Distribution Experimental Center, and its performance fully meets the requirements of new energy use.
Photovoltaic(wind)booster box substation is mainly used for photovoltaic and wind power generation projects. The box materials can be ordinary steel plates, colored steel plates, stainless steel, nonmetals and other materials, and the protection level can reach IP54.
Features:
Easy installation and maintenance, small floor space: box-type substation occupies a small floor space and is suitable for installation in places with limited space. Its size is generally about 3m*12m*3m, and it can be increased or decreased as required.
Good anti-corrosion and waterproof performance: the box-type substation adopts fully enclosed design, and the internal equipment and distribution system are fully protected to prevent corrosion and flooding. The manufacture and assembly of box-type substation generally
Will be completed in the factory, reducing the on-site construction time and cost, but also reduce the skill requirements for construction personnel. Maintenance time also
It can be carried out by remote monitoring, which improves the utilization rate and operation efficiency of equipment.
Convenient transportation and relocation: the box-type substation can be transported as a whole, and only simple foundation treatment is needed when it is placed, so it can greatly shorten the transportation time and reduce the transportation cost. At the same time, if necessary
If it is moved to other power plants, it can be directly moved for use.
Safe and reliable: Box-type substation is highly integrated and self-contained, and its safety and reliability can be improved through intelligent monitoring and control system.
