What Are The Operating Functions Of High-voltage Drop-out Fuses?
What are the operating functions of drop out fuse element?
drop out fuse in transformer consists of three parts: insulating support, moving and static contacts, and fuse tube. The static contacts are installed at both ends of the insulating support, and the fuse tube consists of an inner arc-extinguishing tube and an outer phenolic paper tube or epoxy glass fiber cloth tube.
1. Preparation: Make preparations before operation, select qualified insulating pull rods of corresponding voltage levels, wear insulating gloves and insulating shoes to ensure safety.
2. Check: Before operation, carefully check the name and number of the equipment to determine the correctness of the operation object.
3. Standing position: Choose a position that is convenient for operation. It is generally advisable to stand in front of and below the current operating phase drop out fuse price. If it is an operation on a pole tower, you should also fasten your safety belt.
4. Alignment: Align the drop out fuse set moving contact with its static contact during operation to ensure the accuracy of the closing position.
5. Closing: When closing drop out fuse unit, you need to be quick, decisive, and accurate, but when closing to the bottom, you cannot use too much force to prevent damage to the supporting insulator and other equipment.
