摘要
防晕材料的电阻率具有非线性特性，此特性能改善电力变压器绕组端部绝缘结构的电场分布。通过实验发现，防晕材料的电阻率及非线性系数在一定范围内时，可以明显提高端部的起始放电电压和熄灭电压。
The resistivity of anti-halo material has non-linear property which can improves the field distribution of insulation structure at winding end of power transformer. By experiments, it is found that the resistivity and non-linear coefficient of anti-halo material can help to raise the starting discharge voltage and extinction voltage obviously as their values are in a certain range.
