Overview

Electric furnace transformers are mainly used in resistance furnaces and salt bath furnaces for heat treatment of mechanical parts, powder metallurgy sintering, nonferrou metal smelting, etc. , and can also be used as power transformers for steel making electric arc furnaces. The capacity of electric furnace transformers is configured according to the size of the electric arc furnace and the smelting process. It meets the requirements of the smelting process by means of voltage regulation.

There are two types of voltage regulation:on-load voltage regulation and non-excitation voltage regulation. Large-scale electric furnace transformers with on-load voltage regulation do not have series reactors, and small and medium-sized electric furnace transformers without excitation voltage regulation can be divided into two types with series reactors and those without reactors. The former relies on the input and removal of the series reactor to change the impedance. The latter changes the winding impedance by changing the connection method of the high-voltage winding of the furnace transformer itself.
