Abstract
The invention relates to a portable dual-purpose emergency power supply used for inversion and rectification. According to the structure of the portable dual-purpose emergency power supply, an alternating-current power source and a direct-current power source are connected with the input end of a voltage adjuster through an alternating-current air switch and a direct-current air switch respectively; the output end of the voltage adjuster is connected with a direct-current output branch and an alternating-current output branch. The direct-current output branch is formed by connecting a rectifier, a filter, a voltage stabilizer and a direct-current air switch in sequence. The alternating-current output branch is formed by connecting an inverter, a voltage stabilizer and an alternating-current air switch in sequence. When power failure happens to a substation, the portable dual-purpose emergency power supply used for inversion and rectification can rapidly provide the stable alternating-current power source and the stable direct-current power source and achieve not only inversion from direct current to alternating current but also inversion from alternating current to direct current. It is guaranteed that during full power failure of the substation, regular checking tests and fault post-checking of a protective device can be conducted.
