They are mainly installed in the American box transformer oil, with the transformer, load switch box,  and will not produce any pollution to the transformer oil. The backup melt inside the fuse will break the short-circuit current when the short-circuit current passes through the fuse. The overload melt and backup melt are installed in series in the fuse casing inside the high voltage current limiting fuse. When the overload current exceeds the specified value for a certain time, the overload melt inside the fuse is melted and the circuit is cut off. The product is widely used in wind power generation, solar power generation, tidal power generation and other equipment distribution protection, this fuses can be equipped with fuses action trigger device, for the control system to break the circuit or send fuses and other indicating signals. The product is convenient to replace the fuse, the time current characteristic curve is stable, the error is only plus or minus 10%, the current limiting characteristic is remarkable, the minimum breaking current is 2 times of the rated melt current, the maximum breaking short-circuit current capacity can reach 50KV. 1. Working conditions :a, The ambient temperature is not higher than +40 degrees Celsius and not lower than -40 degrees Celsius.b, Elevation is more than 1000 meters .c, The relative humidity should not be more than 90% of the daily average.d, The surrounding air should be free from corrosive gas or flammable gas pollution.e, The fuse outer transformer oil is no more than 110 degrees Celsius.2.
