| Abstract: | Starting from the electro-magnetic principles, this paper makes a theoretical study of the operation of the low-voltage-large-current transformer for turning three phases into a single phase, obtains the electromagnetic relation of this transformer and the method to ensure the three-phase side current balance. A prototype is developed and used for a electroslag remelter. It has been proved in practice that the unbalance degree of the three-phase side current of this transformer can meet the requirements of the related regulations. |
