摘　　要：针对在不同海拔环境中,塑壳断路器的分断能力会受到大气压等因素影响的情况,研究了不同海拔高度下塑壳断路器的分断能力与工作电压的关系。通过理论分析大气压等因素给塑壳断路器的介电性能带来的影响,以及塑壳断路器工作电压与分断能力之间的关系,得出塑壳断路器的工作电压与海拔高度之间的关系,以及工作电压不变的情况下不同海拔高度下塑壳断路器分断能力的修正曲线。In view of the different altitude environment,the breaking capacity of moulded case circuit breaker（ MCCB） is affected by the atmospheric pressure and other factors. The relationship between the breaking capacity and the working voltage of MCCB at different altitude was researched. The influence of atmospheric pressure and other factors on dielectric properties of MCCB and the relationship between the working voltage and breaking capacity of MCCB were analyzed theoretically. And the relationship between the working voltage of MCCB and the altitude,and the correction curve of the breaking capacity of MCCB at different altitude in constant working voltage were obtained.
