Product Name: Drop-Out FuseModel Number: 12KVPlace of Origin: ChinaFeatures:
1) Drop-out fuse cutout and load switching fuse cutout are of outdoor used
high voltage protective device
2) To be connected incoming feeder of distribution transformer or
distribution lines
3) It mainly protect transformer or lines from short circuit and overload,
and on/off loading current
4) Drop-out fuse cutout is composed of insulator supports and fuse tube,
static contacts are fixed on two sides of insulator support and moving
con-tube, tact is installed on two ends of fuse tube
5) Fuse tube is composed of inside arc-extinguishing tube outer phenolic
compound paper tube or epoxy glass tact and arc-extinguishing exclosure
for switching on/off loading current
6) Under normal conditions the fuse-link is tightened within the fuse tube
to form a closed position
7) If a fault occurs, an electric arc will take place, thus heating the
arc-extinguishing tube
8) This heating action produces high pressure, which explodes, thereby
dropping the fuse tube and placing the cut-out in position
9) To switch off the cut-out, the user needs to pull the insulated
operating bar
10) This action keeps the auxiliary static contact in operation, meanwhile
opening the auxiliary contacts where the arcing is occurring, thus
extinguishing the arc
