Development of Macroscopic and Microscopic Model of SF6 Arc

Abstract

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。 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.
