摘　　要：通过对某电厂过滤器的运行环境、牺牲阳极种类、阳极的设计计算、阳极的安装、运行现状分析,确认其循环水系统碎屑过滤器现有阴极保护系统大体满足防腐蚀的要求。为更好地运行,建议其更换牺牲阳极种类并对不溶解的阳极进行成分分析及电化学性能测试,对采购的阳极进行抽样检测,对每只安装的新阳极测量电连接。Operating environment, type, design, installation,operation status of sacrificial anode were applied to analysis the effect of current cathodic protection system of a circulating water debris filter in the power plant,result shows that the system generally meet the requirements of anti-corrosion. In order to better operation, improvement measures, such as replacing the sacrificial anode and analysising the components and testing electrochemical performance of the insoluble anode, Sampling for testing and measuring the anode electrical connection were proposed.
