It organically combines the functions of transformer step-down and low-voltage power distribution. Together, it is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, movable steel structure box. It is especially suitable for the construction and transformation of urban power grids. It is a new type of steel structure box that has emerged after civil engineering substations. A brand-new substation, the box-type transformer foundation is the architectural foundation of the box-type transformer. By embedding steel plates on the box-type transformer foundation, it provides a balanced and stable foundation for the installation of inverters and box-type transformers. There is a passage for passing cables at the base of the box-type transformer, providing a hidden passage from the combiner box outlet to the inverter incoming line and a passage from the inverter outlet to the low-voltage side incoming line of the box-type transformer.

The existing box transformer foundation is usually made of cement. When installing the box transformer, it needs to be poured on site according to the size of the box transformer. Not only does the construction time take a long time but the labor cost is high. The prefabricated foundation needs to be customized in advance, and the size is not easy to change. , poor versatility, and during use, the fixed box transformer uses an expansion screw to connect the box and the foundation. After the box or the foundation is damaged, it is difficult to disassemble, which brings certain difficulties to replacement and maintenance.

Therefore, it is necessary to propose a box-type substation installation support to solve the above problems.
