线性阳极在阳曲压气站区域性阴极保护中的应用

摘要

陕京三线阳曲压气站新建装置区的区域性阴极保护设计采用了线性阳极地床方式。针对线性阳极电流及电位分布特征，采用闭合回路安装，并设置阳极接线箱。现场测试表明，使用线性阳极克服了站内区域性阴极保护的干扰与屏蔽。%A linear anode ground bed is applied to the regional cathodic protection of Yangqu compressor station in Shanxi-Beijing Gas Pipeline Ⅲ. losed-loop installation and a set of anode junction box are used according to the linear anode current and potential distribution characteristics. Field tests show that the usage of linear anode overcomes the interference and shielding of regional cathodic protection in the compressor station.
