电动汽车（EV）的需求和可持续发展目标一直在增加。快速充电电路是电动汽车的关键技术。为了保护该电路免受故障或事故的影响，需要快速中断由直流接触器（DCC）的切换产生的电弧。然而，DCC具有小的尺寸和相对于朝向灭弧室的电弧延伸的封闭边界。由电极产生的金属蒸汽导致电弧保持在电极之间，而不是向前拉伸，因为气体的导电性增加时，金属蒸汽的污染it.In这项研究中，电弧运动与不考虑金属蒸汽的数值模拟阐明的影响，金属蒸汽对电弧的流动。据观察，从电极产生的金属蒸汽导致再附着现象在阳极侧发生几次，这增加了电弧延伸到灭弧室中的时间。© 2021日本电气工程师协会。出版社：Wiley Periodicals LLC
The demand and sustainable development goals for electric vehicles (EVs) have been increasing. A quick charging circuit is an essential technology for EVs. To protect this circuit from faults or accidents, rapid interruption of the arc generated by the switching of direct current contactors (DCCs) is required. However, the DCCs have small sizes and close boundaries against an arc stretch toward the extinguishing chamber. The metal vapor generated by the electrodes causes the arc to remain between the electrodes instead of stretching forward, because the gas electrical conductivity increases when the metal vapor contaminates it. In this study, the arc movements with and without consideration of the metal vapor were simulated numerically to elucidate the influence of metal vapor on arc mobility. It was observed that the metal vapor generated from the electrodes causes the reattachment phenomenon to occur several times on the anode side, which increases the time of arc stretching into the extinguishing chamber. © 2021 Institute of Electrical Engineers of Japan.
