Differences between DC and AC fuses
The main difference between DC and AC fuses lies in their ability to extinguish arcs. ACuses utilize the zero point of current to help extinguish the arc, while DC fuses require stronger capabilities to extinguish the arc because DC current has no zero point.
Material: The common fusible material for DC fuses is pure silver (for better conductivity and sectionalizing ability), while AC fuses mainly use oxygen-free high- copper as the fusible material. Both use high-purity silica sand to extinguish the arc.
(1) When DC output power is used, its twosided DC system does not need to operate synchronously, while AC transmission must operate synchronously. When transmitting current over long distances, there will be a significant phase difference between the two of the AC transmission system.
(2) The loss of DC transmission in the event of a fault is much smaller than that of AC transmission. If two AC systems are interconnected AC lines, then when a short circuit occurs in one system, the other side will have to transmit the short-circuit current to the fault side.
(3) In use, AC fuses cannot replace DC fuses, but DC can replace AC fuses.
Notice: Please do not replace the fuse casually when choosing it, so as to avoid more serious damage.
