摘　　要：介绍了SF6 高压断路器的2种主要灭弧形式 ,对不同灭弧结构断路器的短路电流开断次数作了详细分析 ,指出一味追求高的开断短路电流次数并不可取。最后对这一指标参数的合理选择提出建议。The two forms of arc extinction of SF6 high voltage breakers are here introduced.Based on the exhaustive analysis of breaking times for different arc extinguishing breakers,it is indicated that the author consider it unwise to pursue more times of breaking short circuit current.Finally,suggestions on resonable selection for the parameters are given.
