- 摘要:
随着中国西部大开发战略的实施,中国西南地区的油气管道建设取得了突飞猛进的发展,但与这些油气管道并行敷设的高压输电线路也越来越多,两者之间产生了难以避免的相互干扰和影响。为保证两者的安全运行,通过对西南地区两段典型的山地天然气管道所遭受的交流杂散干扰电流进行检测和分析,并根据管道所处地区的地形地貌特点,结合现场实际情况,制定了交流干扰防护措施,最后通过对交流干扰防护措施实施后的有效性进行测试分析。比较分析得出：西南山地油气管道遭受交流干扰时,可采用排流井的形式进行交流杂散干扰电流的排流；该种排流方案占地面积小,现场施工简单,排流效果显著,特别适合于环境条件类似的西南山地油气管道交流干扰杂散电流的排流。研究结果为类似条件的山地油气管道交流干扰治理提供了借鉴措施,具有一定参考意义。
With the implementation of the western development strategy in China, the construction of oil and gas pipelines in southwest China has made rapid progress, but there are more and more high-voltage transmission lines laid in parallel with these oil and gas pipelines, which have unavoidable interference and influence on each other.In order to ensure the safe operation of the pipeline and high-voltage transmission lines, the detection and analysis of the AC stray current interference suffered by two typical mountain pipelines in southwest China have been introduced in this paper,and the stray current drainage scheme and measures are formulated according to the special landform characteristics of the mountain pipeline andthe actual situation of the site.Finally, through the test and analysis of the stray current drainage measures after the actual implementation,it is concluded that when the ground pipeline in southwest mountain areas suffers the AC stray current interference, the form of stray current drainage well can be used to carry out the AC stray current interference.This scheme is suitable for the drainage of AC interference current in the southwest mountainous pipeline due to its small land occupation, and it is a way of simple site construction and remarkable drainage effect. The result provides reference for the disposal of AC interference in mountainous pipeline of similar conditions.
