Constant-current type multi-source DC transformer based on aluminum electrolytic bath

Abstract

The invention discloses a constant-current type multi-source DC transformer based on an aluminum electrolytic bath. The constant-current type multi-source DC transformer comprises a DC transformer, a multi-source conversion circuit and a DC constant-current circuit, wherein the DC transformer is connected with the aluminum electrolytic bath and provides a direct current to the aluminum electrolytic bath, the multi-source conversion circuit and the DC constant-current circuit are sequentially connected in series and then connected with the DC transformer, three kinds of power supplies are connected on the multi-source conversion circuit, the multi-source conversion circuit is composed of a switching circuit and a buffer circuit, and the power supplies include a solar power supply, an industrial power supply and a generator powered backup power supply. The constant-current type multi-source DC transformer based on the aluminum electrolytic bath provided by the invention can switch power supplies without shutdown, and better maintains the normal operation of equipment and normal proceeding of production.

Description

technical field [0001] The invention relates to a multi-source DC transformer, in particular to a steady-flow multi-source DC transformer based on an aluminum electrolytic cell. Background technique [0002] Aluminum electrolysis is mainly completed by the aluminum electrolytic cell. The entire electrolytic cell needs DC power supply to complete the process of heating and electrolysis. However, the DC power supply method in the prior art is relatively simple, mainly through the conversion of industrial power supply. High energy consumption greatly increases the burden on enterprises. However, when the power supply is interrupted or the power supply is switched, it is necessary to stop the equipment first and then switch the power supply, which will greatly affect the normal operation of the equipment and the normal production, and also affect the service life of the equipment, which is not conducive to promoting Business and industry development.
