Abstract: In this paper, a new type of solution for the connection between the busbar of the mobile generator and the low-voltage power distribution equipment is proposed. The emergency power supply quick access device quickly and efficiently connects the power supply of the emergency power generation vehicle to the low-voltage distribution cabinet to realize the non-stop operation of the distribution network. The structure and working principle of the device are expounded, the compatibility of the emergency power access device and the busbar of the low-voltage power distribution cabinet is fully considered, and the self-compensating structure ensures the current carrying capacity when accessing various specifications of the busbar. Practical application shows that the device has a simple structure and is easy to disassemble and install. There is no need to transform the original low-voltage distribution cabinet, and the investment and operation cost are low.
Key words: emergency power supply; quick access device; low-voltage distribution cabinet
