摘要:

通过基于绝缘窄缝灭弧原理设计的阻隔式直流快速开断装置,在直流开断冲击试验回路开展燃弧实验,研究了电弧在绝缘窄缝中的发展过程,重点分析了绝缘窄缝截面周长、宽度、高度及有效长度对电弧特性的影响规律。最终,得出了绝缘窄缝各参数对电弧特性的影响规律,为进一步发展阻隔式直流开断方法及设计改良装置提供了思路及实验依据。

Abstract:

The development of the arc in the narrow insulation gap is studied by means of the DC interrupting impulse test circuit.Meanwhile,by means of the blocking DC fast interrupting device,the influence of the section perimeter,width,height and effective length of the narrow insulation gap on the arc characteristics is analyzed.Finally,the influence law of the parameters of the insulation narrow gap on the arc characteristics is obtained,which provides ideas and experimental basis for the further development of the barrier DC interrupting method and the design of the improved device.

Key words: DC circuit breaker, insulation slit, development of arc, blocking DC interrupt
