摘　　要：断路器是保障电力网络安全和可靠的重要设备,气体断路器开断电流时产生开关电弧,燃弧过程是一个时间尺度毫秒级且伴有复杂物理、化学反应的高温暂态过程。受其高温、瞬态特性的制约,在对开断过程气体电弧的研究中,可成熟应用于关键参数测量的方法相对有限。为构建更为精准可靠的电弧模型并开展相关计算,需要获得电弧等离子体在不同条件下的行为机理和关键微观参数,因此需对气体电弧微观参数的测试技术进行进一步的研究。该研究基于XIHARI气体电弧关键参数测试平台,介绍了纹影法和发射光谱法在电弧测试装置上的应用,对比了不同测试方法的原理和适用范围并搭建了相应的光学测试平台,为光学诊断方法在气体断路器开断过程燃弧机理和行为模式研究的应用提供了参考与支撑。Circuit breaker is a significant equipment to ensure the safety and reliability of the power grid.Gas circuit breakers generate arc when switching currents,which is a high-temperature transient process accompanied by complex physical and chemical reactions in milliseconds.Constrained by this,relatively limited methods can be used in the study of the breaking process,especially the testing of key parameters.In order to construct accurate and reliable arc models and carry out relevant calculations,it is necessary to obtain the behavior mechanism and key microscopic parameters of arc plasma under different conditions.Therefore,it is necessary to discuss the testing techniques of microscopic parameters of the gas arc.Based on the test platform of key parameters of gas arc in XIHARI,this paper discussed the application of schlieren method and emission spectroscopy on arc testing device,introduced the principles and application scope of different test methods and built the corresponding optical test platform.It also provided reference and support for the application of optical testing methods in the study of the arc behavior mechanism in the switching process of gas circuit breaker.
