1前言熔断器,也就是保险管,是一种安装在电路中、保证电路安全运行的电器元件。当电流异常升高到一定高度时,保险管会自身熔断切断电流,从而起到保护电路安全运行的作用。保险管广泛运用于电子电路中的保安设备,因此,如果保险管的出库合格率不够高,将会产生成本浪费,影
1 Foreword Fuse, that is, fuse, is a kind of electrical components installed in the circuit, to ensure the safe operation of the circuit. When the current abnormal increase to a certain height, the fuse will fuse itself cut off the current, which play a protective role in the safe operation of the circuit. Fuse widely used in electronic circuits in the security equipment, therefore, if the fuse out of the pass rate is not high enough, there will be a waste of cost,
