摘　　要：电触头的性能直接影响着接触器的可靠运行。利用电接触触头材料综合参数测试仪对交流接触器触头材料的性能进行测试。通过试验架台模拟触头在闭合、开启过程中触头的动态变化,得到了打开、闭合时的燃弧能量、时间曲线,接触电阻、弹跳次数和熔焊力曲线。通过试验确定各种因素对交流接触器触头材料性能的影响。With the rapid development of modern industry,the higher demand of the electrical contact has been put forward.An electrical contact material parameter tester was used to test the electrical performance of the AC contactor＇s contact material.Through the equipment,the dynamic changes of the contact during making and breaking can be simulated.Arcing energy curves,arcing time curves,contact resistance curves,bounce frequency curves and welding strength curves were obtained.Through the test results,the factor influence on the AC contactor＇s contact material properties was determined.
