摘要

由于电荷迁移引起的应力增强是高压直流系统固体绝缘设计中的一个关键因素。讨论了体电流对表面和内部电荷积累的影响;并建立了预测任意构型下的稳态条件的方程,并在环氧绝缘子上给出了实验证据,证明了该分析的有效性。

Bulk charging of epoxy insulation under DC stress
Stress enhancement due to the migration of charges can be a critical factor in the design of solid insulation for high voltage DC systems. The effect of bulk currents on surface and internal charge accumulation is discussed; and equations are formulated which predict steady-state conditions in arbitrary configurations o Experimental evidence is given for the validity of this analysis in epoxy insulators.
