L&R  10kV~24kV Porcelain Drop-out fuse cutout

Product 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.

Drop-out fused cut out is com-posed 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

 arc-estinguishing tube, outer phenolic compound paper tube or epoxy glass tube,Load switching fuse cutout 

provides enforced elastic auxiliary contacts and arcextinguishing enclosure for switchinon/off loading current.

 At normally working via fuselink 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 ex-plode a lot of gas. This will produce high pressure and blow off the arc along with tube.
After fuselink 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 sill.
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.
