摘要
输电线路对输气管道的电磁影响日益突出,为研究具体影响程度,通过现场试验、仿真计算得出750kV交流在输电线路正常运行、事故运行、雷击杆塔3种系统状态时油气管道的感应电压和电流,确定输电线路对输气管道的交流腐蚀强度和输气管道对地电压,评估750 kV交流输电线路对输气管道影响程度,并提出建议防护措施。
Through the field test, the simulation calculation of 750 kV AC transmission line operation accident in normal operation, the lightning induced voltage and current of three kinds of system state oil and gas pipeline, determine the transmission line strength of AC corrosion of gas pipeline and gas pipeline to the earth pressure, the evaluation of 750 kV AC transmission line for gas pipeline the degree of influence, and puts forward some suggestions and preventive measures.
