[0001] The invention belongs to the technical field of prefabricated cabin type substations, and in particular relates to a crawler vehicle type self-propelled prefabricated substation. Background Art

[0002] For open-pit mining (such as coal, copper, gold, diamond, etc.), or large-scale mining in special scenarios such as deserts and snowfields, it is necessary to power the mining equipment. The equipment for supplying large coal mining areas needs to be frequently moved and site changed as the mining area extends. If the site environment is harsh, mostly gravel sandstone, muddy roads or sections of snow all year round, which do not meet the conditions of conventional transportation roads, the seismic requirements of equipment transportation need to be guaranteed during the transfer process. Traditional prefabricated substation equipment is heavy, and the site often does not have the conditions for installing large lifting equipment or transporting equipment (that is, it is difficult for cranes and cars to enter the site), or the site does not have the conditions for leveling the site. In these cases, prefabricated substations are needed to realize automatic mobile site change, fast cable connection, and fast equipment power supply. Summary of the invention
