摘要
详细阐述了触头金属液桥形成的物理过程,说明了金属液桥的几何形貌,并对影响触头金属液桥电压-电流特性的因素进行了论述,理论分析了触头间材料转移方向的物理机理,指出了评价材料桥式转移的方法。并从试验研究和理论分析两方面总结了金属液桥的研究现状、结论及展望。
The physical processes and geometrical morphology of molten bridge between contacts were elaborated in this paper.The factors affecting the voltage and current of molten bridge were discussed.The physical mechanism and the evaluation method of material transfer between contacts were also analyzed.Research status, conclusions and prospects of molten bridge were discussed based on experimental studies and theoretical analysis.
