Drop-out fuse, drop the choice of the switch

10kV drop-out fuse applicable ambient air non-conductive dust, corrosive gases and flammable, explosive and other dangerous environments, the annual temperature difference within ± 40 ° C outdoor venues. Their choice is in accordance with the two parameters of the rated voltage and rated current is the rated voltage of the fuse must match the rated voltage protection device (lines). Drop-out fuse
Fuse with the rated current should be greater than or equal to the rated current of the melt. Rated current of the melt, optional 1.5 to 2 times the rated load current. In addition, should be protected three-phase short-circuit capacity, check the fuse selected. Ensure that the system is protected three-phase short-circuit capacity is less than the upper limit of the fuse rated breaking capacity, but must be greater than the lower limit of the rated breaking capacity. Rated breaking capacity of fuse (usually refers to its upper limit) is too large, is likely to be protected three-phase short-circuit capacity is less than the lower limit of the fuse rated breaking capacity, resulting in the melt fuse is difficult interrupter, the final caused by the melting tube burned, explosions and other accidents. At present, some of the power supply unit is still in the rural power grids peak in the selection of such fuses must be strict product quality, protecting the network of qualified equipment, while noting its rated disconnect the capacity limit and lower limit.
