摘　　要：开断能力是考核低压断路器性能的关键指标。对于利用空气等流体作为灭弧介质的断路器来说,气吹灭弧在很大程度上影响电弧的运动情况,成为影响整个开断过程的主要物理过程之一。由于气吹灭弧过程的复杂性,目前对于其数学模型的建立仍有许多问题尚未解决,特别是与低压断路器开断过程的其他场域相耦合的问题,一直是相关领域研究的热点和难点。围绕低压断路器气吹灭弧的研究历程及其发展现状进行全面分析。The breaking capacity is the key performance index of the low voltage circuit breaker. For circuit breakers using fluid media（for example, air） as arc-extinguishing dielectrics, the air-blast process affects the arc movement to a great extent, and consequently becomes one of the most important physical processes in the interruption process of the circuit breaker. Due to the complexity of the air-blast arc extinguishing process, there are still many problems unsolved in the field of its mathematic modeling, especially the coupling with other component processes that exist in the breaker＇s interruption process has always been a research hotspot and difficulty in related field. A comprehensive analysis on the research progress and development status of the air-blast arc extinguishing of the low voltage circuit breaker is carried out.
