摘要
在考虑变压器油纸绝缘电阻率及相对介电常数受温度影响的基础上,对不同温度下换流变压器主绝缘电场进行了仿真研究,并得到了电场强度变化分布规律。
O n the basis of con sidering the in fluence of temperature on the resistivity and relative permittivity for transformer oil-paper insulation, the main insulation electric fields of converter transformer at different temperature are simulated, and the distribution regu larities of electric field strength are obtained.
