摘　　要：固定式直流融冰是对全线进行融冰,耗能大,融冰慢。粤北山区电力线路并非全线结冰,履冰区一般在线路的中段或中后段。文章提出交流融冰的多种模式,并将融冰装置置于履冰区,只对履冰区进行融冰,实施精准融冰。根据履冰区段的特点,选择不同的融冰模式或多模式组合搭配,能应用在110 kV、35 kV、10 kV线路融冰,且投资少、见效快。The fixed DC ice melting is to melt the whole line,which consumes a lot of energy and melts slowly.The power line in the mountainous area of northern Guangdong is not frozen in the whole line,and the ice area is generally in the middle or middle and back section of the line.In this paper,a variety of modes of AC ice melting are put forward,and the ice melting device is placed in the ice area,only the ice area is melted,and precise ice melting is implemented.According to the characteristics of ice skating section,different ice melting modes or multi-mode combination can be selected,which can be applied to the ice melting of 110 kV,35 kV and 10 kV lines,with less investment and quick effect.
