Cut-Out Fuse
Drop-out fused cut and load switching fuse cutout are of outdoor used high voltage protective device,to be connected with incoming feeder of distribution ransformer or distrbution lines it mainly protect transformer or lines form short circuit and overload,and on/off loading current,drop-out fuse cutout is composed of 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 insied arc-esting uishing tube,outer phenolic compound paper tube or epoxy glass tube,load switching fuse cutout provides enforced elastic auxiliary contacts and arc-extinguishing enclosure for switching on/off loading current.At normally working via fuse link tightened the fuse tube is fixed to formup of close position.In case system occur faults,fault current result in fuse melt immediately and take place electric arc,which let arc-extinguishing tube being heated and ex-plode a lot of gas.This will produce high pressure and blow off the arc along with tube,after fuse link melt moving contact has no tightened strength again,mechanism is locked and fuse tube dropout.Cutout now is in open position.When it needs to switch off during cut out 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 are and the arc will be lengthened in arcextinguishing enclosure gap and meanwhile arc-ectinguishing explode gas to blow off the arc during curing current passing zero.
