PriceList for 630a Switch Fuse Isolator - 10KV,15KV, 25KV, 27KV, 33KV, 38KV IEC&ANSI Standard Medium And High Voltage Porcelain Dropout Fuse Cutout – EC Insulators Detail:
Description
Drop fuse cutouts and load switching fuse cutouts are for outdoor used high voltage protective device. To be connected with in coming feeder of distributing transformer lines it mainly protect transformers or lines from short circuit and overload, and on/off loading current.
Drop out fuse cutout is composed 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-extinguishing tube,outer phenolic compound paper tube or epoxy glass tube.
At normally working via fuse link tightened the fuse tube is fixed to form up of close position. In case system current faults, faults current result in fuse melt immediately and take place electric arc, which let arc-extinguishing tube being heated and explode a lot of gas. This will produce high pressure and blow off the arc along the tube. After fuse link melt, moving contact has no lightened strength again, mechanism is locked and fuse tube drop out.cutout now is open position.
