- 摘要:
- 在长输油气管道与高压输电线路的公共走廊内,当输电系统遭受雷击或发生工频故障时,强电流通过输电铁塔接地极会对附近埋地管道形成电弧冲击危害。采用裸铜屏蔽线与去耦合设施相结合的防护措施是最近10年来国际上比较通行的做法,既可以防护强电冲击,又可以防止交流腐蚀。
In the common corridor of long-distance pipeline and high voltage electrical transmission line,when the electrical transmission system is struck by lightning or has power frequency default, the heavy current will pass through the grounding electrode of electrical transmission steel tower and cause arc impulse harm to nearby pipeline. The protective measure using bare copper shielding wire together with decoupling device is commonly applied in the recent decade, which is able to protect pipeline against heavy current impulse and alternating current corrosion.2010,S1(S1): 70-73 收稿日期：2010-11-18分类号：TE43作者简介：黄留群（1966-），男，高级工程师，工程硕士，主要从事油气储运工程防腐与阴极保护设计、研究工作参考文献：
