 | Product Feature | | | to be connected with incoming feeder of distribution transformer of 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 insulator support and moving contact is installed on two ends of fuse tube. fuse tube,static contactor 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 inforced elastic auxiliary contacts and arc-extinguishing tube, contact and arc-extinguishing enclosure for switching on/off loading current.at normally working via fuse link tightened the fuse tube is fixed to form up of close positon. in case system occur faults, faults current result in fuse melt immediately and take place electric arc,which let arc-extinguishing tube being heated and explode a lot of gas, this willreproduce 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 drop out. cutout now is in open position. when it needs to switch off during cutout loading, operator shall viainsulation operating bar pull the moving contact is contacted still. when it needs to switch off during cutout loading, operator shall viainsulation operating bar pull the moving contact is contacted still. whiling pulling the auxiliary contact is separated between auxiliary contacts there occour electric arc and the arc will be lengthened in arc-extinguishing enclosure gap and mean-while arc-extinguishing explode gas to blow off the arc during current passing zero |
