新疆库车末站阴极保护系统优化研究

Optimization Research on Cathodic Protection System at the Last Station of Kuqa in Xinjiang

新疆库车末站自2004年采用外加电流阴极保护的方法保护站内外设备和管线,但站内各监测点阴极保护电位均不能达到设计要求。利用现有条件,通过技术手段进行电位优化分配,能够使站内外阴极保护达到平衡,有效地保护了库车末站站内外设备和管线。

Impressed current cathodic protection has been adopted at the last station of Kuqa County m Xinjiang since 2004, to protect the equipments inside and outside of the station ,but the cathodic protection potential at every monitoring point inside of the station cannot meet the design requirement.Optimized distribution of the potential can be carried out by technological means and existing conditions.It can use the wires to separately connect the cables connecting to the cathode of junction boxes,which balances the cathodic protection and protects the equipments and pipelines inside and outside the station.
