Abstract

This utility model provides a power supply system for a dehumidifier in a low-voltage switchgear cabinet, comprising: an independent A-section busbar and a B-section busbar; multiple low-voltage switchgear cabinets, each housing a dehumidifier and a power terminal block for connecting the dehumidifier to a power source; a first cable connecting the power terminal block of the first low-voltage switchgear cabinet in the A-section to the B-section busbar, and the power terminal block of the first low-voltage switchgear cabinet in the B-section to the A-section busbar; and a second cable connecting the power terminal blocks of the low-voltage switchgear cabinets in the same distribution section in series. This utility model can improve the power supply reliability of the dehumidifier in the low-voltage switchgear cabinet, while avoiding the safety hazards of electrical equipment under existing power supply methods.
