摘要
研究了不同情况下的变压器油和浸油绝缘纸板的电导率和介电常数,采用有限元软件计算了不同幅值、不同类型电场作用下的油纸绝缘系统内部电场分布特性,提出了混合场强下的电场分布特性。
The conductivity and permittivity of the transformer oil and insulating pressboard are researched. The electric field distribution of oil-paper insulation system under the complex electrical field is calculated by FEM software. The distribution characteristics of electric field under complex fields are presented.
