Gaoya dianqi, 2022 根据导线风阻力的计算原理推导了覆冰导线风荷载增大系数。基于覆冰导线的气动力系数风洞试验结果，分别计算了不同覆冰厚度、不同覆冰种类的圆截面覆冰导线、新月形覆冰导线和D形覆冰导线的风荷载增大系数，给出了便于工程设计和校核使用的覆冰导线风荷载增大系数的取值用表。结果表明，3种覆冰形状导线的风荷载增大系数均受实际覆冰厚度与覆冰种类的影响，其值随覆冰厚度的增大而增大、随覆冰密度的增大而减小。理想圆截面覆冰导线的风荷载增大系数在覆冰密度较小时的部分工况大于规范取值，在覆冰密度较大时均小于规范取值 ...

Gaoya dianqi, 2022 输电线路运行时导线表面的电场强度是影响导线覆冰及其电晕放电过程的重要因素，但现有文献的研究对象多为交流输电线路。为适应中国直流输电线路的建设浪潮，文中在电晕笼中采用人工带电模拟覆冰的方法研究了覆冰电场强度对导线雨凇覆冰形态以及电晕损失特性的影响规律。研究表明：覆冰电场强度对导线雨淞覆冰形态具有显著的影响，覆冰时导线表面电场强度越高，形成的雨淞覆冰导线的覆冰重量和冰凌长度越小、冰凌间距越大、覆冰厚度呈先增大后减小的规律。高覆冰电场强度下形成的雨淞覆冰导线的电晕损失更小，此外 ...

Dianci bileiqi, 2016 四川西部多山,地形、气候复杂,电网覆冰呈现多样化的特点。针对这一现象,选取了大箐梁子、牦牛山、二郎山等典型覆冰地区,对电网的覆冰状况、类型进行了研究。结果发现,地形对覆冰类型具有较大的影响,牦牛山覆冰以雾凇为主,大箐梁子覆冰为硬雾凇和雨凇为主的混合凇,二郎山为软雾凇为主的混合凇。混合凇可完全覆盖绝缘子下表面棱缘,且混合凇覆冰绝缘子串往往存在冰棱。混合凇覆冰情况下,也发现类似雨凇带电覆冰时绝缘子串两侧存在空气间隙的情况。受电场影响,以软雾凇为主的混合凇覆冰绝缘子串两端覆冰明显多于中间 ...

Gaoya dianqi, 2010 输电线路覆冰严重威胁了电力系统的运行安全。在总结中国输电线路典型覆冰事故的基础上,对中国输电线路覆冰事故特点、事故原因及防治技术措施进行了总结分析。分析结果表明:中国输电线路覆冰事故具有覆盖面积大、机械故障和电气故障并存等特点;严重覆冰引起过荷载、不平衡张力、覆冰闪络及导线舞动是造成覆冰事故的主要原因;防冰除冰、防覆冰闪络及防覆冰舞动是防治输电线路覆冰事故的主要技术方向。
