介绍了阴极保护系统的原理及在６００ ＭＷ 机组淡水凝汽器上的应用．该系统采用了多点分散控制的外加电流阴极保护和涂层联合保护的方法，设计新颖，有效地抑制了凝汽器管板和铜管的腐蚀．
The principle of cathodic protection system and its application in freshwater condenser of 600 MW unit are introduced. The system uses a multi-point distributed control of the applied current cathodic protection and coating joint protection method, a novel design, effectively inhibiting the condenser tube plate and copper corrosion.
