Product Description
Drop Out Fuse Cutout is a kind of outdoor high voltage protection device, it is connected with the incoming feeder of the distribution transformer or distribution lines and primarly used to protect transformers or lines against the impact raised by short circuit, overioad and switching curent. The drop-out fuse cutout is composed of insulator support and a fuse carier, statlc contacls that are fixed on two sides of insulator support and moving contact installed on two ends of fuse carrier, The interior of the fuse carier is the extinguishing tube while the exterior is made of phenolic compound paper tube or epoxy glass
During normal operation, the fuse link is tightened to form the closing position. in fault current situation, the fuse link melts and an electrical arc is formed. The arc-extinguishing tube is heated and explosion of gas occurs which causes high pressure inside the fuse carrier tube and makes the tube to separate from the contacts, he contact is relaxed once the fuse element melts.
The fuse cutout is now in the open positlion, the operator needs to switch the curent off. The moving contact can be pulledoff by an insulated hot sticker, The main contact and auxiliary contact are connected
