Drop-out fuse cutout and load switching fuse
cutouts are outdoor high voltage protection devices. They are
connected with the incoming feeder of the distribution transformer
or distribution lines. These are primarily used to protect
transformers or lines from short circuits and overloads and
switching currents. The drop-out fuse unit is composed of insulator
supports and a fuse tube, static contacts are fixed on two sides of
the insulator support and moving contact is installed on two ends
of fuse tube. The interior of the fuse tube is the extinguishing
tube. the exterior is made of the phenolic compound paper tube or
epoxy glass. Load switching cutout fuse provides stretch auxiliary
contacts and arc-extinguish exclosure for switching on/off loading
current. In normal operation, the fuse
link is tightened to form tho closed position. In the fault current
situation, the fuse link melts and an electrical arc is formed. The
arc-extinguishing tube is as occurs. This causes high pressure
inside the tube and causes the tube to separate from the contacts.
The strength of the contact is relaxed once the fuse elements melt.
The cutouts now in the open position, the operator needs to switch
the current off. Then with an insulated operating bar, the moving
contact can be pulled off. The main contact and auxiliary contact
is connected.The technical parameters of the form are for reference
only.Customized products can consult online customer
