摘要
文章简要介绍了电力电磁场与力场的耦合计算,以及仿真系统(NASTEL)采用的输电线路周围电位和电场计算的基本方法,应用该软件计算了新乡220 kV输电线路ADSS光缆周围的电位和电场分布,重点分析了转角和跳线对电场分布的影响,揭示了断缆事故发生的原因,最后针对电力系统ADSS光缆的设计和施工提出了一些建议。
The coupling calculation of electric electromagnetism field and force field, and the basic method utilized in NASTEL simulation software to calculate the voltage and electric field around a transmission line are briefly introduced in the paper. The electric potential and electric field around the ADSS optic cable on 220 kV transmission line in Xinxiang are computed with NASTEL, and the effects of comer and jumping wires upon distributing electric field are analyzed especially, and then the possible reasons of causing the accident are concluded. Finally, some suggestions are put forward in order to guide the design and construction of ADSS optical cable.
