摘要
目前配网线路主要采取的人工除冰方法进行融冰,无法迅速有效地实现除冰。在统计分析湖南部分地区配网线路的型号和长度的基础上,根据各种线型的最小融冰电流和最大融冰电流,经过融冰电压等计算,提出了基于调压整流的直流融冰方法。研制了相应的移动式直流融冰装置,有效地解决了冰灾发生时2km以内长度的任意线型配网线路的融冰问题,能够显著地降低电力设施受冰冻灾害破坏的损失。
Currently,the major manual de-icing methods for distribution lines can not deice quickly and effectively.Based on the statistical analysis of the type and length of partial distribution lines in Hunan power grid,and according to the minimum and maximum ice-melting current and voltage of various kinds of distribution lines,the voltage regulation rectification based DC de-icing method is proposed through the de-icing voltage calculation.Moreover,the de-icing devices based on the proposed method are also developed,which can effectively solve the ice problem of any distribution lines less than 2km.It can significantly reduce the electric power facilities damage caused by the frozen disaster.
