How fuse works when meet abnormal circuit?

Physical process of fuse operation

When the short-circuit fault current passes through, the fuse heats up, the circuit is disconnected after the gap gasification, the voltage between the breakpoints increases, the gap is broken down again, an arc is generated, and finally the arc is extinguished. Therefore, over-voltage may also be generated in the process of fuse cut-off. The amplitude of this over-voltage is related to the cut-off condition of line circuit and the length of the broken gap. Therefore, in operation, it is necessary to summarize the abnormal phenomenon and occurrence probability of fuse cut-off over-voltage, as well as the ability to cut off small fault current, and accumulate data to improve its performance.
