摘　　要：利用虚拟仪器技术测量了触头模拟试验装置通断操作过程中的机电特性,包括闭合与分断过程中的电弧电流与电压、接触压力、触头位移、触头速度等。分析了闭合弹跳发生时触头所处位置和分/合速度最大值、压力最大值与位移的关系等。分析电触头通断过程的机电特性,对探寻电触头最佳工作参数和条件有积极的意义。The electromechanical characteristics of electrical contacts analog test device in on-off operations were measured with the use of virtual instrument, including, the arcing voltage and current, contact force and displacement as well as contact velocity. The location of contact bounce the relationship between the maximum value of contact velocity, force and displacement were discussed. It is useful of researching the best woking perameter and condition of elehrieal contacts.
