摘要
基于尘土颗粒周围电场与其在电接触表面沉积的密切联系导致电接触可靠性下降甚至接触故障,分析了电连接器自身及外加电场对尘土颗粒运动产生影响的过程和机理,提出了衡量电连接器对颗粒吸引能力的判据和计算方法。仿真实验表明,该吸引能力与电连接器两端电压和距离有关,颗粒运动趋势与其进入电场时间有关,而与其所带电荷极性无关。
Based on close relation between electric field around dust particles and their deposition on electric contact surface,which results in contact reliability decline and contact fault,the process and principle,which electric connector itself and external electric fields influence the motion of particles,were analyzed.The criterion and calculation method to evaluate connector attracting particles were proposed.Simulation test shows that the attracting ability is relative to two terminals voltage and distance of...
