Influence of Freezing Rain and Snow Weather on Power Transmission and Transformation Equipment in Jiangxi Power Grid and Countermeasures

摘要

In combination with the factors of formation and features of freezing rain and snow weather in Jiangxi Province,characteristics,cause and harm of typical freezing damage of power transmission and transformation equipment in Jiangxi Power Grid in recent years,such as heavy ice load,galloping of conductor and icing flashover of external insulation,was analyzed.The advantages,disadvantages and applicability of those anti-icing measures which had been carried out were discussed.Several suggestions for anti-icing work for Jiangxi Power Grid are proposed.
