真空开关触头的运动特性研究

Research on The Contact Motion of Vacuum Switches

根据理论模型和实验首先分析了真空开关触头在开断过程中的状态及其运动特性对开断能力的影响,然后描述了开关触头的关合特性。在此基础上,讨论并提出了理想的触头运动特性,在这一特性下能缩短平均燃弧时间,可望改善大电流开断后的触头表面状态。

In this paper,we analysed firstly the electrode states in process of breaking current and their effects to the breaking capacity, then the closing characteristic , based on both of the theoretical and experimental investigations, we give out the discussions about the expected movement characteristics,which can improve surface condition of electrode after breaking high current,and shorten the average arcing time in some extent.
