“小小保险丝,作用真不小。”专业电工和有一定防火常识的人不难理解此话。而现实生活中,人们往往忽视“保险丝”的作用,或图方便省事,或是不懂蛮干,用铁丝、铜丝、铝线等替代保险丝,或采用额定电流过大,直径过粗的保险丝,结果起不到保险作用。从而导致了无数起电气火灾事故。 “Small fuses are very useful.” It is not difficult for professional electricians and people with certain fire prevention knowledge to understand this. In real life, people often overlook the role of “fuses”, or they are convenient to use, or do not know how to use them. Instead of using fuses such as wire, copper wire and aluminum wire, or using fuses with excessive rated current and excessive diameter, The result will not be insured. This led to countless electrical fire accidents.
