| 摘 要： | 在低压、阻性、小电流负载下,用研制的小容量、可变频ASTM电触头通断测试系统获得了50Hz和400Hz下Ag基合金电触头材料的燃弧特征值和熔焊力,用电光分析天平、SEM和EDAX测量与分析了AgNi、AgC和AgW电触头材料的的质量变化、表面形貌与微区组分。研究表明,在低压、小电流条件下,400Hz时CAgC4、CAgW50和CAgNi10三种Ag基合金材料的抗熔焊性和抗烧损性均优于各自在50Hz下的性能。400Hz下,第二组元不同的Ag基合金电触头的抗电弧侵蚀能力不同。其中,CAgC4的喷溅最严重,耐电弧侵蚀能力最差,CAgNi10次之,CAgW50最好。

| Abstract: | The values of arcing characteristics and the welding force of the Ag-based electrical contact material at 50Hz and 400Hz are introduced during the electrical contact current make-and-break test under low voltage,resistive load,small current by a developed ASTM contact material experimental system of small-capacity and variable frequency. By electricity-ray analytical balance,SEM and EDAX,the changes of the contact material weighing,the surface profile and micro-area constituent of AgNi,AgC and AgW contact m... |
