摘要
进线孤立档计算是一个很繁杂的工作,其中控制工况筛选计算需要考虑诸多因素,在阐述变电站进线孤立档特点的基础上,详细分析了孤立档计算的思路和概念,并列表说明相关计算数据和设计成果。
The incoming line isolation span calculation is a very complicated job, and for the control conditions screening calculation, there are a number of problems and factors that need to be considered. Based on the characteristics of incoming line isolated span in substation, the paper elaborates the ideas and concepts of isolated span calculation in an easy-to-speak language, and lists the relevant calculation data and design results.
