        摘  要:發電機斷路器具有額定電流大、開斷短路電流直流分量高、開斷瞬態恢復電壓(TRV)上升快等特點,分析了這些特點產生的原因,并闡述了目前解決這些特性問題的主要方法,即利用電弧特性避免短路電流長延時過零、斷路器兩端加裝吸收電容限制TRV上升率,為大容量發電機選型提供參考。
        關鍵詞:發電機斷路器;非周期分量;瞬態恢復電壓

        Abstract: Generator circuit breakers are with the characteristics such as large rated current, high direct current component of cut-off short-circuit current and fast rising cut-off transient recovery voltage. This paper analyzed the causes of these characteristics and described the main methods solving these characteristic problems at present. The arc characteristics were used to avoid short-circuit current long time delay zero-crossing and the absorbed capacitance limitation was added at both ends of circuit breakers to confine the rising rate of TRV, so as to provide references for large capacity generators.
        Key words: generator circuit breaker; aperiodic component; transient recovery voltage
