触头表面粗糙度对接触电阻影响的探讨

Discussing the Effects of Contact Surface Coarsenesson Contact Resistance

介绍了利用粗糙度测试仪数字化地衡量触头表面质量的方法。分析了粗糙度对电触头 ,尤其是轻负载用电触头接触电阻的影响。

The coarseness testing appearance can show digitally the surface condition of electric contact. Coarseness effects on contact resistance of electric contacts, especially, light_duty ones were analyzed.
