10KV outdoor high voltage drop fuse ceramic fuse switch with arc extinguishing cover

Drop-out fuse cutout

Description:
Drop-out fuse cutout and load switching fuse cutouts are outdoor high voltage protection devices. They are connected with the incoming feeder of the distribution transformer or distribution lines. These are primarily used to protect transformers or lines from short circuits and overloads and switching currents. The drop-out fuse unit is composed of insulator supports and a fuse tube, static contacts are fixed on two sides of the insulator support and moving contact is installed on two ends of fuse tube. The interior of the fuse tube is the extinguishing tube. the exterior is made of the phenolic compound paper tube or epoxy glass. Load switching cutout fuse provides stretch auxiliary contacts and arc-extinguish exclosure for switching on/off loading current.
In normal operation, the fuse link is tightened to form tho closed position. In the fault current situation, the fuse link melts and an electrical arc is formed. The arc-extinguishing tube is as occurs. This causes high pressure inside the tube and causes the tube to separate from the contacts. The strength of the contact is relaxed once the fuse elements melt. The cutouts now in the open position, the operator needs to switch the current off. Then with an insulated operating bar, the moving contact can be pulled off. The main contact and auxiliary contact is connected.
