[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in the power plant is a step-up substation, which boosts the electric energy generated by the generator and feeds it into the high-voltage power grid. As a type of substation, the prefabricated substation is easy to assemble and meets the needs of quickly building a substation at the place of use. The fixed structure is the installation component of the substation, which meets the needs of building and fixing the substation and ensures that the substation can be used effectively and normally.

[0003] After the site is selected, the prefabricated substation on the market is poured with concrete on the ground of the site where the prefabricated substation is to be fixedly installed. Since the prefabricated substation needs to be distributed horizontally during the assembly process, a grinding or cutting device is required to cut and grind the concrete ground to ensure that the prefabricated substation is built horizontally. This installation and fixing method is difficult to operate, which brings troubles to people who need to fine-tune the prefabricated substation. For this reason, we propose a quick fixing structure for a prefabricated substation. Utility Model Content
