电气化铁道对油气管道电磁干扰的计算及防护措施

Calculation on Electromagnetic Interference of Electrified Railway to Oil and Gas Pipeline and Prevention Measure

就电气化铁道牵引供电系统的不对称高压输电线路,主要通过阻性耦合对其附近的油气管道及油库产生电磁干扰,危及设备和人身安全、干扰设备正常工作的问题,简单介绍了电气化铁道牵引供电系统,给出了电气化铁道对油气管道的阻性耦合地电位表达式,并从电气化铁道和油气管道两个方面,总结了减小电气化铁道对油气管道电磁干扰的防护措施,以及电气化区段油库铁路专用线电火花的防护措施。

As a special type of asymmetric high voltage transmission line,traction power supply system could bring electromagnetic interference to oil and gas pipeline and depot near the electrified railway by resistance coupling,which endanger the safety of equipment and human and disturb the normal operation of equipments.The traction power supply system of electrified railway was introduced,and the expressions for the resistance coupling potential of electrified railway to oil and gas pipeline were obtained.The prevention measures to reduce electromagnetic interference of electrified railway to oil and gas pipeline and measures to prevent electric spark of special line of oil depot railway in electrified section were presented from the aspects of electrified railway and oil and gas pipeline.
