High-voltage Transmission Lines On Buried Pipelines Coupling Disturbance Study

With the rapid development of the national economy, the energy industry has become one of the most important for the transmission of electricity and the erection of high voltage transmission line and the laying of oil and gas and more and more of the many buried pipeline. Current high-voltage transmission lines in the frequency of radiation on the electromagnetic field near a buried pipeline induced voltage communicate and cause corrosion. This problem has become increasingly serious importance for the people. How protection, try to avoid stray current corrosion of the pipeline, as well as the protection of pipelines, as well as the corresponding surrounding work, and the safety of civilian facilities to become more and more our concern. In this paper, some aspects of the following research and analysis:(1)Analysis of high-voltage transmission lines on buried pipelines coupled mathematical model of interference from the impact of extraction of buried pipeline induced voltage interference factors, to conduct an independent calculation and analysis, to determine the various interfering factors on the impact of voltage sensor channels that focus on the interference factor for the project provide a theoretical basis for practical application.(2)To carry out laboratory experiments at the basis of theoretical calculations, experimental aircraft interior set up for each of the interfering factors in the laboratory to conduct an independent test, analysis of the actual situation, the induced voltage on the impact of pipeline, in order to interfere with the practical application of the law, as well as summary to provide experimental basis.(3) Preparation software, as well as in the theoretical mathematical model based on laboratory experiments, for sending along the East Sichuan Gas paragraphs soil conditions, establishment of Chuan East gas pipeline sections to send along with the adjacent high-voltage transmission line sensor prediction software. Sichuan Gas to East Pipeline to send laying drainage, as well as future reference.
