Portable AC/DC system for transformer substation

The invention relates to a portable AC/DC system for a transformer substation. The system adopts a digital-analog structure, and comprises a plurality of function module cabins, wherein the function module cabins are arranged in pull rod boxes; the function module cabins comprise a charging cabin, a battery cabin, a control cabin, a feeder line cabin, an inverter cabin and a solar power generation cabin respectively; each pull rod box forms a single module; each module can work independently; and the modules are connected by adopting high-capacity quick connectors to form a perfect AC/DC system. The portable AC/DC system has high independence and integration and good motility and anti-seismic property, and has certain waterproof function, the efficiency and safety performance under field work are improved, a solar power generation module can provide power supply guarantee to the maximum extent, direct economic benefit can be brought, and the system has extremely high popularization and application prospects.
