SF₆电弧宏微观模型研究进展

Development of Macroscopic and Microscopic Model of SF₆ Arc

摘要: SF₆断路器是电力系统中的重要开断设备，断路器的稳定性与可靠性事关电力系统的安全运行。但是SF₆电弧是电场、磁场、温度场以及气流场等多场耦合互相影响不断变化的复杂过程，因此虽然国内外已有很多研究者对SF₆电弧进行了多方位的研究，但是已有的研究都是建立在假设和实验室设定的条件下的。本文基于国内外研究者对SF₆的研究现状以及方向进行了整理归纳，介绍了SF₆研究中宏观和微观模型，并对SF₆电弧的未来研究方向以及亟待解决的问题进行了探讨。

Abstract: SF₆ circuit breaker is important breaking equipment in power system; the operation of the circuit breaker is related to the stability and reliability of the power system. SF₆ arc is a complex multi-field coupling process evolving electric field, magnetic field, temperature field and flow field. Although there are a lot of domestic and foreign researchers conducting studies of SF₆ arc, those previous studies are all based on the assumptions and under the conditions of the specific laboratory setting. Based on the research status of SF₆ arc, this paper introduces the development of macroscopic and microscopic models in SF₆ arc and discusses the future research directions and problems to be solved in SF₆ arc.
