The overall structure design of the vehicle mounted mobile substation is compact, with strong mobility, and can be put into use in a short time. It also has high power supply reliability, flexible operation, simple and convenient assembly, and each component can also be operated and transported separately. The semi trailer is usually in a mobile standby state and can be dispatched upon receiving a departure command. It can be put into operation in the power grid within a few hours of reaching the designated destination, especially meeting the power supply needs of the high-voltage power grid power supply system in substation technical transformation, equipment maintenance, temporary power supply on construction sites, emergency repair, and natural disaster situations.
