Under the condition of diffuse type of vacuum arcs the contacterosion rates in ac vacuum contactors are analysed.
在扩散型电弧条件下对交流真空接触器触头侵蚀的特点进行剖析。
2
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.
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。

Thereby, study on electrical contact materials which have the strong anti-electrical erosion has important significance.
