摘要
采用光谱诊断方法,利用光栅光谱仪结合高速摄影机等仪器对压气式模型灭弧室中的SF_6气吹电弧进行了光谱分析,获得了开断过程中喷口喉部弧柱径向平均温度的动态特性。试验结果表明,在开断过程中,喷口电弧(电流峰值750 A)最高温度可达23000K.同时还获得了开断过程中喷口喉部弧柱径向平均温度的变化范围。试验结果都是对选取的Cu_1原子谱线进行分析后获得的。最后,在光谱分析的基础上分析了弧柱内的能量耗散。
The spootroscopic investigation of the SF6 arc in a model puffer interrupter has been made with a spectroscope and a high speed camera. The experimental results show that, for the SFe nozzle arc (peak current 750 A). the highest tempraiure would be 23 000 K. The temporal decay of average radial arc temierature at th(?)at - during the last half loop cf arc current, was in the range of 9 000-15 000 K. in his paper all the experiment results were derived from Cu spectral lines and from the results of spectroseonic investigation. The energy dissipatior. mechanism in arc column was analysed.
