摘　　要：通过分析2002～2005年间约400多份型式试验报告、原始记录及试验波形,并且跟踪一台合成试验用辅助断路器单极近一年的开断情况,得出目前在制造工艺和技术水平方面,真空断路器的开断潜力还远远没被认识到。The conclusion is obtained that the potential of breaking capacity for vacuum circuit breaker has not been recognized yet, according to the manufacturing processing and technology level at present through analyzing four hundred type test reports from 2002-2005, while tracking an assistant circuit breaker used in synthetic test for nearly one year.
