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 shortcircuit and overload, and on/off loading current.

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 tube2. Outer phenolic compound paper tube or epoxy glass tubeLoad 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 makesarc 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.
