摘　　要：为保证导线间和导地线间不同期脱冰的静态接近电气安全距离,通过对典型5档线路不均匀冰模型在不同工况下所要求的垂直线间距离进行计算,讨论了在不同档距情况下上层导地线覆冰状态校验条件,并给出了垂直线间距离推荐值,可为500 k V重冰区同塔双回线路塔头设计提供参考。The application of video monitoring system to the auxiliary system in smart substation is introduced , and the applica-tion situation of intelligent linkage between video monitoring system and substation supervision control system are introduced too.The main way at present adopted by video monitoring system and supervision control system in smart substation is dis -cussed , and 5 feasible intelligent linkage modes are given .The different ways are studied and analyzed as viewed from the in-put mode, the application mode, the economy, the reliability and the applicability and so on , and thus the application pros-pects of different ways of linkage are put forward .A combined linkage with good practicality for the advanced application of video linkage in smart substation is proposed , which has been successfully applied to 110 kV smart substation .
