摘要
研究了直流12～60V、1～8A阻性与感性负载条件下,Ag及AgCdO触头材料分断电弧中金属相电弧转变为气相电弧的过程及转折点.在以气相电弧为主的电弧中,金属相燃弧时间趋于不变.作为评价触头的性能,不能单一地比较其燃弧时间的长短,尚应全面评价其分断电弧能量和材料侵蚀率.
In the paper, the process of metallic phase arc turns to gaseous phase arc and their turning point for Ag and AgCdO contact materials is studied at DC 12-60V l-8A and resistive load and inductive load. When the gaseous phase arc is mainly in break arc, matallic phase arc time is about constant. When we evaluate the property of contact materials, we should not only compare thier arc time, but also compare thier erosion rate of materials and arc energy.
