强电线路下的阴极保护管道交流干扰防护措施
Protection of Alternating Current Interference to Cathodically Proteceded Pipelines under Power Transmission Lines
摘 要
在总结国内外最新交流干扰防护措施及工程实践的基础上,指出固态去耦合器接地是目前强电线路下的阴极保护管道减轻交流干扰和抗强电冲击有效措施,实践中各种排流设备因检验手段和检测标准的缺失存在的风险也是不容忽视的问题.

Abstract
Power transmission lines can cause alternating current interference corrosion of buried pipelines when they share a “public corridor” with the pipelines.On basis of summarizing the practice of alternating current interference protection at home and abroad,the article points out that solid-state decoupler earthing is the most effective measures for reducing alternating current interference and resisting strong electric shock.Nevertheless,the risks of various drainage arrangements due to the lack of testing instruments and standards can not be neglected in practice.
