Abstract：In this paper, according to the two failures of the breaker in the sectionalized connection of the single bus in the power supply system of the ATC building,it combines with the logic principle of the secondary control switching action of the power supply system. The problems of the power supply system in the two failures and the design defects of the secondary circuit of the power supply system of the ATC building are found. Two improvement schemes are proposed for the latter. It is proved by practice that the improved scheme not only solves the problem of design defect of secondary circuit,and improves the reliability of the power supply system of the ATC building.
