High Voltage Expulsion Dropout Fuse Cutout

Drop-out fuse cutout and load switching fuse cutout are of outdoor used high voltage protective device. To be connected with incoming feeder of distribution transformer or distribution lines, it mainly protect transformer or lines from short circuit and overload, and on/off loading, current. Drop-out fuse cutout is composed of insulate insulator supports and fuse tube, static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube. Fuse tube is composed of inside arc-extinguishing tube. Outer phenolic compound paper tube or epoxy glass tube, load switching fuse cutout provides enforced elastic auxiliary contacts and arc-extinguishing enclosure switching on-off loading current.
At normally working via fuse link tightened the fuse tube is fixed to form up of close position. In case system occur faults, fault current result result in fuse melt immediately and take piece electric are, which let arc-extinguishing tube being heated and explode a lot of gas, This will produce high pressure and below of the are along with tube. After fuse link melt moving contact has no tightened strength again, mechanism is locked and fuse tube drop out, Cutout now is in open position. When it needs to switch off during cutout loading, operator shall via insulating operating bar pull the moving contact, at its beginning main contact and auxiliary static contact is contacted still, Whiling pulling the auxiliary contact is separated between auxiliary contacts there occur electric arc and the arc will be lengthened in arc-extinguishing enclosure gap and meanwhile arc-extinguishing explode gas to blow off the arc during current passing zero.
