输电线路短路电流对埋地管道电位抬升及抑制方法研究
Research of the short-circuit current of transmission line on potential rise of buried pipeline and its suppression method
摘要
Abstract
Aiming at the problem of the proximity of transmission lines and buried pipelines in cities,through the estab-lishment of a line-tower-grounding-buried pipeline integrated model,comprehensive consideration is given to the process that the shunt of adjacent towers and lightning conductors and the fault current entering the ground via the tower grounding grid.Based on this model,the effect laws of soil resistivity,proximity distance,pipeline parameters,crossover angles,and different current supply methods on the potential of metal pipelines and corrosion resistance voltage are studied.Re-search on the suppression method of pipeline potential rise can also be carried out for transmission lines,which provides guidance on the safety protection of adjacent fuel(gas)pipelines when a ground short circuit fault occurs.关键词
