摘要
随着我国经济建设的持续快速发展,管道与高压输电线交叉现象越来越普遍。通过山东某输气管道现场调研建立了管道经高压输电线的交流干扰仿真模型,研究了高压交流输电线对埋地管道的干扰规律及管道排流点设置位置对排流效果的影响规律。结果表明:管道中感应电势与高压输电线中运行电流成正比,管道与高压输电线的交叉点感应电势最大,且沿交叉点向两侧递减,且随着交叉角度减小,管道中的感应电势逐渐降低,且降低趋势渐趋平缓。在对以上规律研究的基础上,制定了某输气管道排流治理方案,优化了排流点。
With the continuous and rapid development of China’s economic construction,the crossing phenomenon of pipeline and high-voltage transmission line is becoming more and more common.The interference simulation model of high voltage transmission line was established through field investigation of Shandong transmission pipeline.The interference rule of high-voltage AC transmission line on buried pipeline and the influence law of the position of drainage point to drainage effect were studied.Results showed that the induced potential in the pipeline was proportional to the running current in the high-voltage transmission line.The maximum value of the induced potential in the pipeline appeared at the intersection.The induced potential decreased to both sides from the intersection.With the decrease of the crossing angle,the induced potential in the pipeline gradually decreased,and the decreasing trend gradually became gentle.Based on the above research,a scheme for the discharge treatment of alternating current interference was established and the drainage point was optimized.
