摘要
基于1台开有观察窗的可拆试验模型,研究了C_5F_(10)O-CO_2混合气体的自由燃弧特性,并测量了电弧电压、电流和发射光谱,通过Abel逆变换得到了电弧的二维分布特性。试验结果表明,CO_2和28%C_5F_(10)O-72%CO_2混合气体的电弧比SF6气体波动更剧烈;在CO_2气体中加入C_5F_(10)O后,气体电弧的稳定性得到改善,且能够显著降低电弧温度。
SF6 is a serious greenhouse gas,and recently,O and its mixtures attract great attention as a potential newly enviromental-friendly insulating medium. This paper experimentally studies the arcing characteristics of C5F10O-CO2 mixture,with an experimental model with viewing windows,and measures the arc voltage,current and emission spectrum. Then the two-dimensional distribution of arc is obtained and analyzed by the inverse transformation of Abel. The results show that,the C5F10O-CO2 mixture arc is more volatile than SF6 gas,and adding C5F10O into CO2 improves the stability of the arc,and significantly reduces the arc temperature.
