摘要
介绍了钢质管道的两种阴极保护系统:牺牲阳极阴极保护系统和强制电流阴极保护系统,并对两种系统的优缺点进行对比;介绍了管道阴极保护中所使用的电源类型并对各种电源适用场合及优缺点进行对比;介绍并对比了几种阴极保护电位的测量技术;统计和分析了钢质管道阴极保护的相关专利和文献的发表状况;最后提出了我国阴极保护存在的一些问题并提出未来的研究方向。
Two kinds of cathodic protection systems were described:sacrificial anode cathodic protection system and forced current cathodic protection system.The advantages and disadvantages of the two systems were compared.The types of power supply used in pipeline cathodic protection were introduced,and the advantages and disadvantages of various power supply applications were compared.Several cathodic protection potential measurement techniques were introduced and compared.The publication status of related patents and documents were counted and analyzed.Some problems of cathodic protection and the future research directions were put forward.
