摘要
气体火花开关在大电流工作情形下 ,会因为开关电极受到高能量、大电流电弧的烧蚀作用而影响其工作性能和寿命。本文根据电极电弧的烧蚀模型 ,通过热传导的计算 ,推导出了几个实用的公式 ,指出了选择耐烧蚀电极材料的原则和减少气体火花开关电极烧蚀的方法。
The electrode erosion of gas spark switch caused by high current,high energy arc influences the feature and lifetime of the switch.According to the model of electrode erosion,authors induce seve- ral formula on the basis of solution for the heat conduction equation.The principle of choosing electrode material and feasible methods of reducing electrode erosion are also presented.
