composite cutout insulator and load switching fuse cutour insulator are of outdoor used high voltage protective device.To be connected with incoming feeder of distribution transformer or distribution line it mainly protect transformer or line from 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 inside arc-estinguishing tube,outer phenolic compound paper tube or eposy glass tube,Load switching fuse cutout provides enforced elastic auxiliary contacts and arcing-extinguishing enclosure for switching on/off loading current.At normally working via fuslink tightened the fuse tube is fixed to from up 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 explode a lot of glass.This will produce high pressure and blow off the arc along with tube.After fuselink 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 cutout loading,operator shall via insulating operating bar pull the moving contact,at its begining main contact and auxiliary static contacted still.Whiiling pulling the auxiliary contact is separated between auxiliary contacts there occur electric arc will be lengthened in arc-extinguishing enclosure gap and meanwhile arc-extinguishing explode gas to blow off the arc during current passing zero.
Purchase notice:
1.Specification and pattern of the bothside fitting.the size of hole should specify,otherwise carry out be IEC.
2.The main dimension and rate voltage.
3.The colour of silicon rubber,usually it is red or gray.
4.Other particular requirement.
