Product Description

Description
Drop-out fused cut out and load Switching fuse cutout are of outdoor used high voltage protective device.
To be connected with incoming feeder of distribution line it mainly protect transformer or lines from short
circuit and overload, and on/off loading current.

Standard: IEC 60282-2
 
Components
Drop-out fused cut out is composed of insulator supports and fuse tube. Static contacts is fixed on insulator
support and moving contact is installed on two ends of fuse tube.
Fuse tube is composed of:
1. Inside arc estinguishing tube
2. 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.
 
Operating Principle
1. When working normally, fuse link tightened the fuse tube to be close position.
2. If system occur faults, big fault current melts fuse immediately and take place electric arc, which makes
arc extinguishing tube being heated and explode a lot of gases. This will produce high pressure and blow off
the arc along with tube.
3. After fuselink melt moving contact has no tightened strength, mechanism is locked and fuse tube dropout.
4. Cutout now is in open position. Operator shall use insulating Link Rod to pull the moving contact.
