In this paper the temperature of the local arc propagating along a polluted dielectric-surface was measured by the method of relative intensities of spectral lines. Four spectral lines with different wave length of sodium atom were selected in measuring the arc temperature by Boltzmann's Graphical Method. In order to measure the arc tempe- rature on cross section of the arc column continuously a optical scanning system composed of 1 lens and 30 rotary flat mirrors was built up. By means of this system the temperature...

In this paper the temperature of the local arc propagating along a polluted dielectric-surface was measured by the method of relative intensities of spectral lines. Four spectral lines with different wave length of sodium atom were selected in measuring the arc temperature by Boltzmann's Graphical Method. In order to measure the arc tempe- rature on cross section of the arc column continuously a optical scanning system composed of 1 lens and 30 rotary flat mirrors was built up. By means of this system the temperature of the arc variation in time was measured. Synchronizing this system with a magnetic tape data recorder and a high speed camera, the whole process of the local arc developing along the polluted surface until flashover was recorded. The measured max. tempe-rature of the arc core reached about 12500K. It is just the temperature of complete joni-:zation of sodium atom. The results of our experiment should be aimed at the research on the mechanism of pollution flashover.

本文从热力学角度出发,用谱线相对强度法对沿染污绝缘表面延伸的局部电弧温度进行了测量。试验选用了钠原子四条不同波长的谱线,用玻耳兹曼图解法求得电弧的温度。为了连续跟踪测量电弧截面的温度变化,采用了由一个透镜和三十个平面镜组成的光学旋转扫描系统,测量了沿染污绝缘表面发展中电弧截面温度随时间的变化。该测温系统与磁带记录仪和高速摄影机联用,测得局部电弧沿染污绝缘表面发展直至闪络的全过程。在临界闪络时,电弧中心的温度高达12500K,这个数值已接近钠原子全电离温度,试验结果有助于污闪放电机理的研究。

The flashover process of electric arc propagating along a polluted dielectric surface was taken by a high speed camera, the applied voltage and leakage current were taken down in the same time. This paper described physical characteristics of contaminated flashover arc under AC voltage and polarity effect in different half cycle. The maximum arc velocity just before flashover and critical flashover voltage and arc length were measured. These parameters should be aimed at research on the mechanism of pollution...
