Structural characteristics of large-capacity DC filter reactor for metal smelting furnace

The filter reactor of the metal smelting furnace is very important to the solid power supply, and it has two functions. First, make the output current of the rectifier smooth and stable. Second, when the inverter thyristor is short-circuited, the growth rate of the short-circuit current and the size of the maximum short-circuit current are limited. If the parameter design of the filter reactor is unreasonable, the core material is not good or the manufacturing process is not good enough, it will have a great impact on the working reliability of the metal smelting furnace.
