摘　　要：以哈尔滨—大连电气化铁路和东北输油管网为研究对象,通过实际测试分析,阐述了电气化铁路对临近输油管道产生交流干扰的基本规律,提出以钳位式排流为主的方法对东北输油管网进行综合防护,并对排流效果进行了客观分析,总的结果表明,排流装置发挥了应有的作用。另外,在交流干扰排流效果传统评价指标——持续干扰指标的基础上,提出了间歇干扰补充评价指标——干扰频率的概念。Taking Ha-Da Electrified Railway and Northeast Oil Pipeline as a research object This paper describes the basic rules of AC interference with oil pipeline from electrified railway in vicinity based on the tests and analysis applies the clamping current drainage method as a main method to comprehensively protect Northeast Oil Pipeline and analyses the good current drainage effects.Furthermore on the basis of traditional evaluation specification of AC interference current drainage effects i.e.sustained interference specification it puts forward the concept of the intermittent interference complementary evaluation specification — interference frequency.
