摘 要:管道或输电线路路由不当时,输电线路将会对附近埋地管道产生较强的电磁干扰。通过分析输电线路与管线的交叉角度、并行长度及并行间距等因素变化时对管道电磁干扰影响的规律,在输电线路与管道路由选择过程中,应尽量增加输电线路与管线的交叉时,应尽量增加其交叉角度,交叉角度一般应≥35°,避免交叉角度≤10°,严禁出现3°左右的交叉角度;当输电线路和管线无法避开,并行长度≤10km时,应尽早避开,以减小交流干扰;管线与高压输电线路并行时,一般间距应≥200m;当并行间距较小时,应尽量≥100m;严禁管线与输电线路的并行间距接近平均线高。Improper selection of the route of pipeline or power transmission line will make power transmission line produce stronger electromagnetic interference on neighboring buried pipeline. In light of the law of electromagnetic interference on the pipeline produced by factor changes such as cross angle of power transmission line with pipeline and their parallel length and spacing, it is necessary to increase their cross time and make cross angle larger than or equal to 35 degrees, to avoid as early as possible the parallel of power transmission line with pipeline so as to de- crease AC interference if their parallel length is less than or equal to 10 kilometers and never allow their parallel spac- ing to be close to average line height, generally larger than or equal to 200 meters if they are parallel.
