It organically combines transformer voltage reduction and low-voltage power distribution functions, making it particularly suitable for urban power grid construction and renovation. It represents a new type of substation that has emerged after traditional civil engineering substations. Prefabricated substations are suitable for mines, factories, oil and gas fields, and wind power stations, replacing traditional civil engineering substations and becoming a new type of complete power distribution system.

[0003] Chinese Patent No. CN109586177B discloses a portable high- and low-voltage transformer substation with protective functions, including a transformer substation cabinet, a transformer, and a mobile vehicle.
