Feedback system of aluminum foil last-stage formation electrolysis power supply and feedback method thereof

Abstract

The invention discloses a feedback system and a feedback method of an aluminum foil last-stage formation electrolysis power supply. The system comprises a cell end voltmeter, a cell end voltage electric quantity isolation sensor, a machine end voltmeter, a machine end voltage electric quantity isolation sensor, a relay, a circuit unit adjusting unit, a change-over switch SB, an electrolytic cell A and an electrolytic cell B, when in use, the cell end voltage is connected to the cell end voltmeter and the cell end electric quantity isolation sensor and then is connected with the relay, a high-voltage direct-current voltage signal of the cell end voltage is converted into a direct-current low-voltage signal of 0-10V through the cell end electric quantity isolation sensor, and the direct-current low-voltage signal is input into the circuit unit of the electrolytic power supply for processing; and then the voltage is transmitted to the adjusting unit for comparison processing, the feedback voltage value is compared with the given voltage of the electrolytic power supply, and the adjusting control system of the electrolytic power supply adjusts the magnitude of the pulse trigger signal of the electrolytic power supply according to the compared data, so that the voltage-stabilized or current-stabilized operation of the electrolytic power supply is realized.

Description

technical field [0001] The invention belongs to the technical field of electrolytic formation of aluminum foil, and in particular relates to a feedback system and a feedback method of an electrolytic power supply for final-stage formation of aluminum foil.
