摘要
直流接触器在控制直流电路开关中起到重要作用。基于Eindhoven模型计算氢氮混合介质电弧物性参数,基于磁流体动力学原理进行电弧仿真,对氢氮灭弧介质进行分断试验,为直流接触器的设计提供参考。
DC contactors play an important role in the control of DC circuit switches.The physical parameters of hydrogen nitrogen mixed medium arc are calculated based on Eindhoven model,the arc is simulated based on the principle of MHD,and the breaking test of hydrogen nitrogen arc extinguishing medium is carried out,which provides a reference for the design of DC contactor.
