摘要
当前国际上推出一批新一代塑壳断路器 ,和原有断路器相比 ,其体积小、分断能力大 ,这是由于采用了新的限流技术。分析了这些新技术 ,并介绍其结构上的特点。
New types of molded case circuit breakers are presented in recent years. Comparing with old type, they are with small size and high interruption capacity, which is due to new current limiting technology used. Those technologies were analysed and the other features of them were also introduced in the paper.
