Abrégé

The present invention relates to the technical field of aluminum electrolytic tank power supply. Provided is a power supply apparatus in which a distributed photovoltaic direct current is connected to a direct-current bus of an aluminum electrolytic tank, which power supply apparatus aims to directly supply a direct current to the aluminum electrolytic tank by means of photovoltaic power generation. The power supply apparatus comprises multiple photovoltaic strings, eight photovoltaic combiner boxes, four electric energy router PET modules, four feed-in protection modules, two feed-out circuit breaker modules and two electrolytic aluminum bus protection modules, wherein the multiple photovoltaic strings are gathered and connected to the photovoltaic combiner boxes, and every two photovoltaic combiner boxes are jointly connected to one electric energy router PET module; each electric energy router PET module is respectively connected to one feed-in protection module; every two feed-in protection modules are jointly connected to one feed-out circuit breaker module; the two feed-out circuit breaker modules are respectively connected to one electrolytic aluminum bus protection module by means of one bridge aluminum bar; and the electrolytic aluminum bus protection modules are directly connected to an electrolytic tank bus. The present invention has the advantages of direct photovoltaic power supply, stability, and low energy consumption.
