摘要

通过工频电弧试验

模拟了与输电线路接近的埋地金属管道在雷击下可能遭受的烧蚀。通过多组实验的对比

分析了电弧对PE防护层管道烧蚀过程中影响最大的参数

并进行了其与电弧烧蚀深度、烧蚀体积之间关系的拟合分析。最后通过对比空气中及砂土中的试验

证明了空气与砂土中电弧烧蚀规律的一致性。试验结果为埋地管道的防雷设计提供了依据。

Abstract

Through the power frequency arcs tests

the ablation of the buried metal pipes close to the transmission lines in the lightning strikes is simulated.By comparison of multi-group tests

the important factor to the ablation degree is found

and it’s relation to the ablation depth & volume is conducted regression analysis.By contrasting the test data in air and sand

the coherence of arcs ablation rules in air and sand is proved at last.The result of the tests provides valuable reference materials to the lightning protection of the buried metal pipes.
