- Inquiry
Drop-out fuses and composite drop-out fuses are outdoor high-voltage protective appliances.
They are installed on the high-voltage side of the distribution transformer or on the branch line of the distribution line, and are used for short-circuit, overload protection and load current separation and combination of transformers and lines.
The drop-out fuse consists of two parts: an insulating bracket and a fuse tube. The static contact is installed at both ends of the insulating bracket, and the moving contact is installed at both ends of the fuse tube. The fuse tube consists of an inner arc-extinguishing tube and an outer phenolic straight tube or epoxy glass cloth tube.
The composite drop-out fuse has enhanced elastic auxiliary contacts and extinguishing shields to separate and combine current.
2. Application
35KV50HZ>2000
3. Use conditions
Applicable to the upper limit of ambient temperature °, the lower limit of Celsius
Altitude does not exceed the wind speed of no more than 3.

5. Model description
6. Installation instructions
During installation, the fuse should be tightened so that the fuse is subjected to a tensile force of about 100%, otherwise it is easy to cause the contact to heat up.
The fuse should be installed firmly and reliably on the cross arm frame without any shaking or swaying.
The fuse tube should have a downward inclination of °±°, so that the fuse tube can fall quickly by its own weight when the fuse is blown.
The fuse should be installed on a cross arm frame with a vertical distance of not less than 1000m from the ground. If it is installed above the distribution transformer, it should maintain a horizontal distance of more than 1000m from the outer contour boundary of the distribution transformer to prevent other accidents caused by the fuse tube falling.
The length of the fuse tube should be adjusted appropriately, and the duckbill tongue should be able to hold more than two-thirds of the contact length after closing the switch to avoid the false operation of falling by itself during operation. The fuse tube should not be blocked by the duckbill to prevent the fuse tube from falling in time after the fuse is blown.
