中文摘要：

采用原位反应合成法制备CuO含量分别为10%、12%、15%的AgCuO电触头材料，在不同电流条件下对这3种触头材料的燃弧时间、燃弧能量、熔焊力、接触电阻等电接触性能进行了测试分析。结果表明：AgCuO电触头材料的分断燃弧时间随CuO含量的增加而增大；CuO含量为10%的样品（AgCuO（10））分断燃弧时间最为稳定；随电流的增大，AgCuO电触头材料的熔焊力不同程度地增加；电流小于20A时，CuO含量为12%的AgCuO（12）抗熔焊性较好；电流大于20A后，CuO含量为10%的AgCuO（10）抗熔焊性较好。原位反应合成法制备的AgCuO电触头材料的接触电阻随电流增大呈现出下降的趋势。

英文摘要：

AgCuO electrical contact material was prepared by in-situ reaction synthesis method, in which CuO content were 10%, 12%, 15%. Under different current conditions, the three kinds of contact materials properties of arc duration, arc energy, welding force, contact resistance were investigated. The results show that, with the increase of CuO content, the breaking arc duration of AgCuO electrical contact material increases. AgCuO （10） is more stable than the other samples of breaking arc duration. With the increase of current, the welding force of AgCuO electrical contact materials increases in different degrees. When the current is less than 20A, AgCuO （12） in the fusion welding performance is better than others. When the current is greater than 20A, AgCuO （10） in the fusion welding performance is more excellent. The contact resistance of in-situ reaction synthesis of AgCuO electrical contact material decreases with the increase of current.
