摘　　要：为了指导复合材料横担在重冰区的应用,本文开展了玻纤增强复合材料及复合材料绝缘横担的覆冰特性研究。结果表明:空白样品在垂直悬挂方式下的覆冰量和冰闪络电压均优于水平悬挂样品,且覆冰量均少于对应的亲水性的纯铝棒和Q345钢棒;涂覆PRTV涂料的复合材料样品覆冰量比空白样品少,对应的闪络电压大幅提升,且对应样品的冰面粘附力值最小,为纯铝棒冰面粘附力值的19%,而空白样品的冰面粘附力值为纯铝棒的78%。硅橡胶复合绝缘横担的覆冰特性正好和复合材料试样相反,水平悬挂方式下复合绝缘横担覆冰量相比垂直悬挂的同规格复合绝缘子减少了30%,闪络电压提高了51%。In order to guide the application of composite cross arms in heavy ice areas,we investigated the icing characteristics of glass fiber reinforced composite material and composite insulated crossarms in this paper.The results show that the icing amount and ice flashover voltage of blank sample under vertical suspension are better than that of horizontal suspension,and its icing amount is less than that of pure aluminum rod and Q345 steel rod with the corresponding hydrophilic.The icing amount of the composite material coated with PRTV coating is less than that of the blank sample,its flashover voltage increases sharply;the ice surface adhesion value is the least,which is 19%of ice surface adhesion value of pure aluminum rod,while the ice surface adhesion value of the blank sample is 78%of pure aluminum rod.The ice coating characteristics of the silicone rubber composite insulated crossarm are just the opposite of that of the composite material sample.Compared with vertical suspending the same composite insulator,when the insulators are horizontal suspending,the icing amount of composite insulated crossarm suspension reduces by 30%,and the flashover voltage increases by 51%.
