摘　　要：利用电光分析天平、扫描电镜与能谱仪,测量并分析了CAgCdO与AgSnO2In2O3触头材料在交流50/400 Hz和小电流通断试验的重量、表面形貌及组分的变化,探讨了两种频率下AgMeO触头侵蚀机理。结论指出,在设计时可适当减少中频开关电器体积。By electronic analytical balance,SEM and EDS, the changes of CAgCdO and AgSnO2 In2O3 contacts material＇s weight ,surface profile and constituent during the test process of AC 50 Hz/400 Hz in small current were observed and analyzed. The mechanism of AgMeO contact erosion under the conditions of two frequency was discussed. The results showe that the size of medium frequency switching device can be reduced.
