摘要: A power supply system for arc furnace is described. The power supply system includes a power converter and a polyphase transformer. The power supply system further includes first disconnecting means connecting the input of the power converter to the primary circuit, second disconnecting means connecting the output of the power converter to the primary circuit, and the power supply system further includes a control circuit configured to control the power converter to supply the electrode and to stabilize the courant and the voltage delivered by the grid to reduce reactions in the grid when the first disconnecting means are open and the second disconnecting means are closed, and to control the power converter to stabilize the courant and the voltage delivered by the grid to reduce reactions in the grid when the first disconnecting means are closed and the second disconnecting means are open.
