Gaoya dianqi, 2019 平行平板电容器结构简单,为了保证电容值的精度,避免外界杂散电容的干扰,常采用增加屏蔽电极的方法来减小外界干扰。文中利用Ansys进行建模仿真,对常用的电容分压器的屏蔽结构进行计算分析,并提出一种增加内部多层屏的新型屏蔽结构,经仿真验证,此方法可以有效提高分压器抗干扰效果。

Gaoya dianqi非交联绝缘材料具有优异的电气机械性能，同时生产能耗少、可回收利用，成为目前电缆绝缘料的研究热点，但与之匹配的非交联半导电屏蔽料的研究还鲜有报道。导电炭黑的分散性对屏蔽料的性能影响重大。文中选用线性低密度聚乙烯（LLDPE）为基体树脂，白油为分散剂，采用熔融共混法制备了非交联电缆屏蔽料。研究了白油含量对屏蔽料中炭黑分散、结晶性能、体积电阻率和机械性能的影响。结果表明添加白油会促进炭黑的分散，但白油含量过大会降低屏蔽料的结晶度，增加其体积电阻率并降低拉伸强度和断裂伸长率。当白油含量为2 wt%时 ...
