摘要

在中国西北的一些高海拔地区

低温持续时间较长

硅橡胶性能改变而引起沿面闪络电压的变化对电力系统有很大影响

因此

研究低温环境对硅橡胶绝缘材料沿面闪络电压的影响以及低温下硅橡胶绝缘材料的闪络电压随温度变化的规律

了解低温下硅橡胶性能改变是否是造成绝缘子闪络事故的原因具有重要意义。为此

在低温下采用恒温试验箱对复合绝缘子用硅橡胶材料进行了低温冷冻处理

在不同温度的低温条件下采用平头板电极模拟不均匀电场

对不同Al（OH）

含量的硅橡胶试样进行了沿面闪络电压的测定。实验结果表明:随着温度的降低

硅橡胶材料沿面闪络电压呈线性增加的趋势

其性能改变并不是造成低温下硅橡胶绝缘子闪络事故的原因。

Abstract

In some high altitude regions of Northwest China

because the low temperature duration is long

the change of surface flashover voltage has a great influence on the power system. So it is of great significance to study the influence of low temperature environment on the surface flashover voltage and temperature dependence of flashover voltage of silicone rubber insulation material under low temperature

to know whether the change of silicone rubber performance is the cause of insulator flashover accident

thus the constant temperature test box is used to treat the sili-cone rubber composite insulator at low temperature. The surface flashover voltage of silicone rub

ber samples with dif-ferent content of Al（OH）

is measured at different temperatures

using flat plate electrode to simulate the uneven elec-tric field. The experimental results show that the surface flashover voltage of silicone rubber increases linearly with the decrease of temperature

it is not the cause of flashover of silicone rubber insulators under low temperature.
