Influence of mitigating wire parameters on mitigation effect of AC interference in long-distance pipelines
As a drainage ground bed,the mitigating wire is an important part of the solid state decoupler+mitigating wire drainage mode.The different grounding materials,forms,and embedded manners of the mitigating wire will have a great impact on the drainage effect.In this paper,the influence of different mitigating wire materials,forms,and embedded manners on the drainage effect was studied,and factors such as the grounding material and size of the mitigating wire,the distance between the mitigating wire and the pipeline,the length of the mitigating wire,and the location of the mitigating wire on the AC interference drainage effect were determined.The zinc strip is determined to be the optimal drainage grounding material.When the distance between the mitigating wire and the pipeline decreases,the overall AC voltage of the pipeline drops and the drainage effect gets better.When the length of the mitigating wire increases,the AC voltage of the pipeline decreases.When the mitigating wire is longer than 1 000 m,the drainage effect is not significantly improved.When the radius of the zinc strip of the same volume is 0.006 m,the mitigation effect is the best.When laying the mitigating wire,it is best to put its center in the place with the highest AC interference voltage.If conditions do not permit,the mitigating wire needs to be moved to the parallel area to the greatest extent,and its center should be as close to the peak voltage position as possible.
