摘要
随着超高压电网的发展出现了大功率的电力枢纽,其特点是在这些电力枢纽附近短路电流值非常大,需要计算地线热稳定,本文对纯钢绞线地线、钢绞线地线与 OPGW、良导体与 OPGW 之间的配合计算加以研究,本文提出计算方法对该类工程的计算有一定的指导意义。
Along with the development of EHV electric power network the great power hinges have appeared,one of its featuresis with very high short circuit current value nearby it,so that the thermal stabilization of the grounding cable has to be calculated.Inthis paper,the cooperate-calculations about pure steel twist wire grounding cable,steel twist wire grounding cable and OPGW,andgood-conductor and OPGW has been discussed.The calculation method presented in this paper would be with certain instructionsense to this kind of engineering.
