Launch pad of radio and television stations belongs to the important power load custom.The original single-channel power supply system worked with a greater security risk,and could not meet the requirements of normal broadcast transmitting station signal.In this paper, an instance of the transformation of the low voltage distribution systems on a dual power automatic switching system works to control the functions and working principle. Practice has proved that after the completion of the design： Dual power method of Maln-Backup Power Automatic Transfer System achieves functional of electricity users, with a good application and promotion of value.
