摘要
针对熔断器在电路正常负载下发生熔断这一误动作现象 ,通过理论分析认为造成熔断器误动作的原因是过大的接触电阻 ,提出了识别这种误动作现象及排除误动作故障的方法。
Through analyzing the theory,it deals with that fuse in circuit with normal load melts wrongly is because of high touch resistance,and explains how to identify fuse melting wrongly, and how to exclude the fault. Therefore we cannot add fuse radius when fuse in circuit melts wrongly.
