Abstract
The utility model discloses a novel portable direct-current power supply. A transformer and a rectifying device are fixed on a dolly body. The top part of the dolly body is provided with a control panel. Four corners of the bottom part of the dolly body are provided with universal wheels. The transformer is provided with an input interface through an alternating-current air switch. The transformer is connected with the rectifying device. The rectifying device is provided with an output interface through a direct-current air switch. The alternating-current air switch and the direct-current air switch are installed on the control panel. According to the utility model, the portable direct-current power supply drives direct-current loads in a direct-current screen replacing process, so that transferring of the direct-current loads between a new direct-current screen and an old direct-current screen is avoided, the load transferring time is reduced, the time for direct-current screen replacing is further shortened, and the reliability of the transformer station direct-current power supply is improved at the same time.
