Gaoya dianqiGIS中盆式绝缘子表面在外施直流电压时会积聚大量电荷使得沿面闪络电压大幅降低，从而引发一系列电气设备故障。基于上述问题，文中分析了盆式绝缘子表面电荷的来源与传导途径，采用有限元仿真计算方法构建了二维轴对称仿真模型以及设定相关参数，研究了电压极性、不同电压幅值以及电压极性反转对盆式绝缘子表面电荷分布的影响。结果表明，在直流电压下，凹面主要积聚与外施直流电压极性相反的电荷，凸面主要积聚与直流电压极性相同的电荷，且凹面积聚的电荷密度更大；在极性反转后-100 kV直流电压下 ...

Gaoya dianqi, 2015 气体绝缘组合电器（gas insulated switchgear,GIS）在电力系统中占有重要地位,盆式绝缘子是GIS内部重要的部件,其表面放电是影响GIS安全运行的重要因素,文中在盆式绝缘子表面设置了典型的绝缘缺陷模型,利用紫外成像仪记录了其表面放电引起紫外光子发射的整个过程,分析了典型放电缺陷模型下的放电电压与光子数之间的关系,对绝缘子表面放电进行了探索,取得的结论:1表面放电紫外光子数随着缺陷尺寸的增大有增大趋势,但是多次重复性实验表明存在饱和特性 ...
