固态去耦隔直排流技术应用现状

Application Status of Solid State Decoupling DC Discharge Technology

埋地钢质管道在受到严重的交流干扰时,人身安全、管道设备、阴极保护有效性均会受到一定程度的影响。工程上普遍利用固态去耦合器连接管道和接地极的做法减轻交流干扰。在国内管道交流干扰排流工程中固态去耦合器得到大量的应用,突显出排流效果不理想和阴极保护存在负面影响等问题。亟待解决排流设计不合理、缺乏排流效果现场检测评价指标及方法、以及相关标准规范的不完善等问题。

When the buried steel pipeline is subjected to severe AC interference,the personal safety,pipeline equipment and cathodic protection effectiveness will be affected to some extent..In the project,solid-state decouplers are commonly used to connect pipes and grounding poles to reduce AC interference.Solid-state decouplers have been widely used in domestic pipeline AC interference drainage projects,highlighting problems such as unsatisfactory drainage effects and negative effects of cathodic protection.It is urgent to solve the problems of unreasonable drainage design,lack of on-site inspection and evaluation indicators and methods,and imperfections of relevant standard speci cations.
