摘要
以典型的电气事故为引子,从保护的需求和保护装置的发展角度,介绍了熔断器的不同分类方法和主要优缺点。结合熔断器在电路中所扮演的角色和动作特征,介绍了它的选用方法,以期为使用者安全使用熔断器提供参考。
Taking the typical electrical accidents as an example,also in view of protection requirement and development of protective apparatus,the main advantages and disadvantages of fuses and fuse classification were analyzed and compared.Based on it,the selection of design scheme of fuses was given out.How to recognize role and characteristics of fuse and give its full play in different conditions were presented.It could provide references for the people how to safely use the fuse.
