Drop-out fuse function and working principle
RW12-10/100A, RW12-10/200A drop-out fuse and pull the load drop is outdoor high-voltage electrical fuse. It means the distribution transformer or distribution lines high side branch trunk road, as a transformer and line short-circuit, overload protection, close the load current. Drop-out fuse holder and fuse tube made ​​of insulating two parts, the static contact mounted on an insulating stand at both ends, the moving contacts mounted on both ends of fuse tube, wire tube by a layer arc tube and the outer layer of the epoxy glass composition. Pull Load drop-out fuse auxiliary contacts and increase flexibility interrupter cover, close the load current.
RW12-10/100A, RW12-10/200A drop-out fuse in normal operation, the fuse tube fuse tensioning means formed after the closed position. When the system fails, the fault current to rapidly blown fuse, and the formation of the arc, arc tube by the arc burning, decomposition of large amounts of gas, so that the formation of a high pressure tube and pipe formed along the longitudinal blow, the arc is rapidly stretched extinguished. Fuse blows, the lower movable contact lose tension and the next turn, release the locking mechanism fuse tube, fuse tube drop, form a distinct breaking position. When you need to pull the load, pull the moving contact with the insulating rod, then take the initiative, to help contact remains stationary contacts, continue to use the insulating rod pulling contacts, auxiliary contacts are separated from the auxiliary arcing between the contacts, the arc in the arc chute is elongated slit while interrupter cover the production of gas in the current zero, the arc is extinguished.
