"the drop fuse is disconnected by the fuse in the fuse, so that the dynamic contact above and below the fuse tube loses the tension of the fuse, so the upper and lower static contact springs and their own weight are under the weight of the fuse., the fuse tube will quickly drop, and the drop fuse will disconnect, thereby interrupting the faulty circuit or faulty equipment to protect them from short circuit or overload damage."
1. the operating sequence of the three-phase high-voltage drop-out fuse. during power failure operation, the middle phase should be pulled first, and the two sides should be pulled later. When the power is transmitted, the two sides are first combined, and then the middle phase is combined. The reason for pulling the middle phase first during a power failure is mainly to consider that the current when the middle phase is cut off is smaller than that of the side phase (a part of the circuit load is transferred to two phases), so the arc is small and there is no danger to both sides....
2. Operation sequence for power outage of distribution transformer: in general, when power outage, the low-voltage switch on the load side should be opened first, and then the high-voltage drop-out fuse on the power supply side should be opened. in the case of multiple power sources, power outages in the above order can prevent the transformer from being reversed.
