[0002] For rescue work, electricity is an indispensable forerunner, and for power workers, it is necessary to ensure that emergency power supply on site can be restored with high quality in the shortest time possible.

[0003] At present, the means adopted are "power facility emergency repair + emergency generator to ensure supply". Generally speaking, the whole process from power facility emergency repair to power restoration is time-consuming and laborious. In the early stage, emergency generators can be used to generate electricity in isolated islands to serve key users such as command centers, medical assistance points, and lighting. The existing low-voltage distribution devices have few power distribution levels and cannot match multiple load points, let alone meet the temporary electricity needs of the masses (such as mobile phone charging, temporary heating, etc.). In addition, the power generated by high-power emergency generators cannot be fully utilized.
