低压熔断器和断路器的比较及应用

Comparison and Application of Low Voltage Fuse and Circuit Breaker

从配电线路的保护要求和保护电器发展的角度 ,分析和比较了熔断器和断路器的主要优缺点。在此基础上 ,给出了设计中有关熔断器和断路器的选型方案。指出应正确认识熔断器和断路器各自的作用和特点 。

In view of protection requirements and development of protective apparatus, the main advantages and shortcomings of fuses and circuit breakers were analyzed and compared. Based on it, the selection of design scheme of fuses and circuit breakers were given out. How to recognize role and characteristics of fuse and circuit breaker correctly and give its full play in different conditions were presented in this paper.
