A lithium iron battery-based direct current power supply emergency response system for a transformer substation, constituted by portable split-body structural units, and the portable split-body structural units are connected in manner which allows quick plugging and unplugging. The portable split-body structural units comprise: a lithium iron battery unit, a distribution control switch unit consisting of two air circuit breakers (K3, and K4), an inverter unit consisting of an inverter, a charging control unit consisting of an alternating current air circuit breaker (K1), a direct current air circuit breaker (K2), a regulator, and a monitor. The present invention has a compact unit structure, allows convenient transportation and on-site assembly, meets the needs for responding to a power system emergency, and can be used as a backup power source when the direct current power source of a transformer substation undergoes on-site maintenance. |
