摘要

不同温度下SF

混合气体的周围离子平均自由行程和热运动速度不同

使SF

混合气体放电过程呈现不同特性。为此

在极不均匀电场、雷电冲击电压下研究了温度对SF

混合气体放电特性的影响。在正负极性的雷电冲击电压下分别测量冲击击穿电压和预放电电流波形

并分析了不同温度下SF

混合气体的预放电现象、步长时间、电晕起始场强及击穿场强。此时试验温度范围设为-20

0℃。结果表明:步长时间、电晕起始场强、击穿场强呈现较大的随机性。负极性雷电冲击电压下步长时间均长于正极性雷电冲击电压下步长时间。负极性冲击电压下10%SF

-90%N

混合气体的电晕起始场强和击穿场强随着温度升高而增高。本研究结果对柜式气体绝缘开关设备和气体绝缘金属封闭输电线路设计具有一定的研究意义。

Abstract

The ions mean free path and the thermal motion speeds are different at different temperatures around SF

mixed gas

thus SF

mixed gas discharge exhibits a different characteristics.Therefore

under the severe non-uniform electric field and lightning impulse voltage

we studied the breakdown characteristics of SF

mixed gas along with the temperature change.Moreover

under the positive and negative polarity of lightning impulse voltage

we measured the impulse breakdown voltage and pre-discharge current waveforms

and analyzed the pre-discharge phenomenon

stepping time

corona onset el

ectric field

and breakdown strength in SF

mixed gas at different temperatures.The temperature range during experiment was set from-20 ℃ to 20 ℃.Results show that the stepping time

corona onset electric field strength

and breakdown field strength present great randomness.The stepping time under negative polarity impulse voltage is longer than that under positive polarity impulse voltage.Under the negative polarity impulse voltage

as the temperature increases

the corona onset electric field and the breakdown strength of 10%SF

-90%N

mixed gas will increase.The results are of certain research significance in the design of cubicle gas insulated switchgear and gas insulated metal-enclosed transmission line.
