Outdoor Pole Mounted High Voltage Porcelain Drop-out Fuse Cutout with Arc Distinguisher

Introduction:
Dropout Fuse Cutout is a kind of outdoor used high voltage
protective device. To be connected with incoming feeder
of distribution transformer or distribution line it mainly
protect transformer or lines from short circuit and overload,
and on/off loading current.
Dropout 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 extinguishing 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 form 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 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 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.
