摘要
电触头是高、低压电器中的关键元件,其性能直接影响到电器运行的可靠性。研究电弧对触头的能量输入和触头的响应具有非常重要的意义。对AgSnO2 和AgNi两种触头材料在不同的电压、电流等级下,进行了大量的试验,对直流分断电弧由金属相电弧向气相电弧转换的规律进行了探讨。
Contacts are the key components of electric apparatus. In order to enhance the reliability of electric apparatus, it’s important to study the arc energy impregnation and response of contacts. In this paper, a lot of experiments were conducted to study the arc transition from metallic phase to gaseous phase in the interruption of DC arc under different voltage and current for AgNi and AgSnO 2 contact materials by utilizing the developed equipment.
