24KV 27KV 100A/200A Porcelain Fuse Cutout Cut Out Fuse

Description: 

China Fuse Manufacturer Aidun Electric produce  "Solarson" brand 24KV 27KV 100A/200A Porcelain Fuse Cutout Cut Out Fuse .

The Fuse Cutout are connected with the incoming feeder of the distribution transformer or distribution lines. These are primary used to protect transformers or lines from short circuits and overloads and switching currents. The drop out fuse unit is composed of insulator supports and a fuse tube, static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube. The interior of the fuse tube is the extinguishing tube, the exterior is made of phenolic compound paper tube or epoxy glass.

Drop-out fuse cutout and load switching

Drop-out fuse cutout and load switching fuse cutouts are outdoor high voltage protection device. They are connected with the incoming feeder ofthe distribution transformer or distribution lines. These are primarly used to protect transformers or lines from short circuits and overloads and switching curents.

The drop-out fuse unit is composed of insulator supports and a fuse tube, static contacts is fxed on two sides of insulator support and moving contactis installdl on two ends of fuse tube. The interior of the fuse tube is the extinguishing tube, the exterlor is made of phenollc compound paper tube or epoxy glass. Load switching cutout fuse provides stretch auxilary contacts and arc-extinguishing exclosure for sitching on/off loading current.

In normal operation the fuse link is tightened to form the closed position. In fault current situation, the fuse link melts and an electrical arcis formed. The arc-extinguishing tube is heated and explosion of gas occurs. This causes high pressure inside the tube and cause the tube to seperate from the contacts. The strength of the contact is relaxed once the fuse elements melt,

The cutout is now in the open position, the operator needs to switch the current of. Then with an insulated operating bar, the moving contactcanbe pulled off. The main contact and auiliary contact is connected.
