交流电气化铁路对埋地金属管道的电磁干扰及防护研究

Research on Electromagnetic Interference of AC Electrified Railway to Buried Metal Pipeline and Its Protection

由于中国基础建设的快速发展,在铁路建设过程中,电气化铁路与埋地金属油气管道的交叉时有发生,因此引起了一系列埋地金属管道的电磁干扰问题。本文结合工程实例,通过建模、实地勘测等手段,对电气化铁路引起的埋地金属管道电磁干扰进行了评估,为交流电气化铁路对埋地金属油气管道的电磁干扰防护提供了参考依据。

According to the rapid development of China's infrastructure,the crossing of electrified railways and buried metal oil and gas pipelines occurs oftenlyduring the construction of railways,causing a series of electromagnetic interference problems for buried metal pipelines.Based on engineering examples,this paper evaluates the electromagnetic interference of buried metal pipelines caused by electrified railways by methods of modeling and field surveys,and provides a reference basis for the protection of electromagnetic interference of buried metal oil and gas pipelines by AC electrified railways.
