Abstract
The utility model relates to a portable inversion and rectification dual-purpose emergency power supply. AC power is connected with the input end of a voltage regulator through an AC air switch and DC power is connected with the input end of the voltage regulator through a DC air switch. The output end of the voltage regulator is connected with a DC output branch and an AC output branch. The DC output branch is formed by a rectifier, a filter, a voltage stabilizer, and a DC air switch which are successively connected. The AC output branch is formed by an inverter, a voltage stabilizer, and an AC air switch which are successively connected. The portable inversion and rectification dual-purpose emergency power supply may quickly supply stable AC power and DC power when a transformer station is powered off, and achieves inversion from DC to AC and inversion from AC to DC. Regular checking tests and verification after faults of a protection device are guaranteed during a transformer station full cut-off period.
