摘要
就鹤管对储罐内电荷的泄漏速度和油面电位的影响进行了分析。将鹤管等效为储罐对称轴上的接地导体,推导了静电场边值问题的解析解。利用解析解,分析鹤管对电荷泄漏速度和油面电位影响后所得到的结论是:鹤管不能加快罐内电荷的泄漏速度,但能降低油面电位,影响程度和储罐的形状及接地导体的半径有关。
Investigated is the effect of filling pipe on the charge relaxation and the oil surface potential at the interface between vapor and oil in a cylindrical vessel.Assimilating the filling pipe to a grounded conductor at the axis of the vessel,the electrostatic boundary problem is solved analytically.By the analytical solution,such conclusion is obtained that existence of the filling pipe can't accelerate charge relaxation,but can reduce surface potential and the effect is determined by both the vessel aspect ratio and pipe radius.
