Physical and Chemical Analysis of Contact Points Wear of Electromagnetic Relay

, 1998
电磁继电器是各类自动化系统中重要的一种基础元件.由于它频繁工作在开关状态，外部振动或温度变化可能引起继电器触点表面氧化或磨损，从而电接触电阻增大，对电接触性能产生不良影响.借助扫描电镜（SEM）和X射线衍射仪（Xrd）对电接触表面进行观察和测量.实验结果表明，经长期连续使用后触点表面变得粗糙并发生磨损，其组分中含有C、CE、Ag等原子.最后对继电器早期失效机理进行了讨论.Electromagnetic relay is an essential element in various automatic ...
