| 摘 要： | 多电和全电化是未来飞机的发展趋势,针对这种趋势,必须研制和发展相应电压等级的供配电电器.为此,设计了3种可用于270*#V直流断路器的灭弧室模型雏形,通过实验和理论计算,研究分析了电弧运动通道对断弧效果的控制作用.试验结果表明:采用适宜的电弧运动通道,可以有效地控制电网严重故障时电路的分断过程,抑制预期故障电流峰值,减少热允通能量.理论计算分析表明,这种改善效果直接和电弧通道上的吹弧磁场分布有关.

| Abstract: | Plane parts will be powered electrically more and more in the coming future, development of aero electrical apparatus becomes the basis of this tendency. Three kinds of electrical arc quenching models were designed for uses with 270 voltage direct current network sources. Based on the experimental and calculation results, It was found that the magnetic distribution in electrical arc running channel can be used to control electrical arc interruption effect under serious network source fault. |
