iron core of the electric furnace transformer
Product Introduction
Transformers designed to provide power for all kinds of electric furnaces. Resistance furnace transformers are used in resistance furnaces and salt bath furnaces for mechanical parts heating, heat treatment, powder metallurgy sintering, non-ferrous metal smelting, etc.Due to varying resistance levels of the heating elements during operation, a resistance transformer is necessary between the furnace and the power grid to regulate and adjust the input voltage for the electric furnace. Small-capacity, low-voltage resistance furnace transformers and salt-bath furnace transformers are mostly dry-type transformers with box shells and natural cooling; medium-capacity (hundreds to thousands of VA) resistance furnace transformers are mostly oil-immersed self-cooling transformers;For larger capacities, forced oil circulation water-cooled transformers are utilized
Structural features
The iron core of the electric furnace transformer is made of high-quality oriented silicon steel sheets, which is processed by automatic cutting line, 45 degree full bevel seam, no punching, and no weft glass adhesive tape binding process. The coil adopts the latest international primary longitudinal insulation structure , and the structure and insulation of the winding are reasonably selected to ensure that the winding has sufficient mechanical strength.It has the characteristics of strong short-circuit ability, strong overload ability, high efficiency, low loss, safety and reliability. The capacity of the electric furnace transformer 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 pressure regulation.There are two voltage regulation modes: on load voltage regulation and non excitation voltage regulation. Large furnace transformers with on load voltage regulation do not have a series reactor, and small and medium-sized furnace transformers with non excitation voltage regulation can be divided into two types: those with a series reactor and those without a reactor. These two types of structures can change the impedance under the highest two voltages.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 windings of the furnace transformer itself.
