摘要:
针对西北地区输电线路和埋地油气管道相邻交叉,输电杆塔接地体可能在雷电冲击下对油气管道放电的情况,通过试验的方法确定了针电极对油气管道间砂质土壤的平均击穿场强,分析了临界击穿场强的影响因素,并对土壤的击穿机理进行了讨论。试验结果表明沙质土壤中针电极对管道的临界击穿场强为200~300 kV/m,土壤电阻率对土壤的临界击穿场强影响不大,为确定西北砂质土壤地区输电线路和埋地油气管道的安全距离提供了参考数据。
Abstract:
The grounding conductors of the transmission lines were likely to discharge to the oil-gas pipeline when the transmission tower was stroked by lightning as they were close to each other or cross each other in Northwest China. In this paper the critical breakdown strength of sandy soil between needle electrode and oil-gas pipeline was determined based on modeling experiments and the influence of the critical breakdown strength was analyzed. Besides, the mechanism of soil breakdown was discussed. The results of the experiment show that the critical breakdown strength is 200~300 kV/m and irrelevant to grounding resistance,which provide reference data to set the safe distance between the transmission lines and the oil-gas pipelines in sandy soil area of Northwest China.
