Drop-out fuse selection
The 10kV drop-out fuse is suitable for outdoor places where there is no conductive dust, no corrosive gas, easy to burn, explosive and other dangerous environments in the surrounding air, and the annual temperature difference ratio is within ±40 degree . The selection is based on the two parameters of rated voltage and rated current, that is, the rated voltage of the fuse must match the rated voltage of the protected equipment (line). The rated current of the fuse should be greater than or equal to the rated current of the melt (generally the rated current of the melt can be 0.3 to 0.1 times that of the fuse), and the rated current of the fuse should be 100kVA and below, taking 2 to 3 times the rated current Current, 1.5 to 2 times the rated current above 100kVA. In addition, the selected fuse should be checked according to the three-phase short-circuit capacity of the protected system. Ensure that the three-phase short-circuit capacity of the protected system is less than the upper limit of the rated breaking capacity of the fuse, but must be greater than the lower limit of the rated breaking capacity.
