摘　　要：基于相同的50 Hz、400 Hz频率及试验电流条件,介绍了常用开关电器触头材料在通断过程中特性参数的统计数据和变化规律,给出了试验总方案,分析了各种触头材料的燃弧能量及时间、熔焊力、接触电阻、电弧长度等性能。试验结果表明,频率为400 Hz时触头材料耐弧侵蚀能力较50 Hz更好。Based on the same testing current with 50 & 400 Hz frequency,the statics and changing criteria of parameters in the make-break process of commonly-used contact material for switching devices were proposed.The main testing scheme was given and the properties like the arc energy,arc time,welding force,contact resistance and arc length were analyzed.The result show the contact material s erosion resistance ability of 400 Hz is better than that of 50 Hz.
