fuse wire 作保險絲用的金屬絲;保險絲,熔絲,熔(斷)線。

fuse-link

When circuitry malfunction happens , the current is so strong that the fuse wire melts and breaks , and the active joint is released , as a result , the fuse tube falls and the electrical circuit is shut off 當線路發生故障時,故障電流使熔絲熔斷,活動關節被釋放,熔管迅速跌落,將電路切斷。

When running normally , a high - voltage explosion fuse is in series with the electrical circuit , the fuse wire is strained and the active joint is locked 跌落式高壓熔斷器又稱噴射式熔斷器,正常運行時串聯在電力線路中,熔絲處于拉緊狀態,活動關節被鎖緊。
