In today's society with the rapid development of science and technology, convenience has become an important criterion for people to choose things. The box-type substation designed in this paper is the most time-saving and cost-saving facility in the substation. Box-type substation can meet the design requirements of high-voltage power receiving, transformer voltage-reducing and low-voltage power distribution. At the same time, the box-type substation has a series of advantages, such as easy to move, small size, less investment, short production cycle and complete functions. In this paper, the current situation of box substation is deeply studied and analyzed, on the basis of which, the design of box substation is carried out, and the technical features, system composition and problems to be avoided are discussed in detail.
