Abstract: Taking the 660MW indirect aircooled unit in a power plant as an example, the two accidents of aircooling system occurred in system operation were analyzed. The operation characteristics and matters needing attention of the indirect aircooling system were expounded. The measures were given when the circulating pump of the indirect aircooling system had tripped or the circulating water had been cut off, and the safety of the unit operation was improved.
