摘要
空气开关电弧是以空气为灭弧和绝缘介质的低压电器中最为复杂的物理现象。针对电弧运动过程特别是电弧背后击穿现象、电弧温度、电弧组分及其浓度等方面,综述了CCD和光纤阵列、光谱诊断技术及磁测试技术等低压空气开关电弧的现代测试技术的特点及其应用,并指出了空气开关电弧实验研究中所面临的几个问题。
Air switch arc is the most complex phenomenon in low voltage electric apparatus using air as quenching and insulation medium. With regarding to arc motion process, especially, arc back commutation phenomenon, arc temperature, arc composition and the corresponding concentration, the characteristics and application of modem measurement technologies including CCD, optical fiber array, spectrum diagnostics and magnetic diagnostics were reviewed. Finally, some important problems in the experimental studies of arc switching arc were pointed.
