Gaoya dianqi, 2016 随着特高压电网的建设,复合绝缘子以其优异的性能已被大量采用,然而表面电荷积聚将导致其沿面闪络电压下降,影响电网运行的稳定性。为了研究表面电荷的积聚效应,建立了复合绝缘子二维轴对称模型,并使用COMSOL软件对该模型进行了研究。研究表明:伞群表面是电荷积聚的主要位置,当其积聚电荷的极性不同时,对原电场分布的影响也不同。分析认为,负极性电荷积聚为电子越过伞群向前发展创造了有利条件,缩短了爬电距离,这可能是导致复合绝缘子闪络电压下降的原因;又对表面电荷积聚情况进行了实验测量 ...

, 2012 本发明涉及一种脉冲放电冷轧辊表面造型的方法。该方法利用脉冲放电能量在轧辊表面形成熔池，同时产生高电弧压力，在高电弧压力、电极和轧辊一定的作用距离下，轧辊表面的熔化物被吹起，熔化物经自淬火冷却后在轧辊表面形成具有凹坑和凸起的造型点，其中凸起具有高硬度。对于不能通过快速熔凝获得高硬度的冷轧辊材料，通过对轧辊表面的熔池添加合金元素进行合金化，保证凸起的高硬度。通过控制加工参数可以调整造型点的分布，使造型点相互分开，保留原始表面。与其他制作表面粗糙元的方法相比，冷轧方法加工速度快，生产效率高 ...
