Intelligent compartment centralized multi-backup LED power supply and use method thereof

Abstract

The invention discloses an intelligent compartment centralized multi-backup LED power supply and a using method thereof.The intelligent compartment centralized multi-backup LED power supply comprises a bottom plate, an annular groove, supporting columns, an annular plate and a fixed folded plate, the annular groove is formed in the top of the bottom plate, four sets of evenly-distributed supporting columns are installed on the bottom wall of the annular groove, and the annular plate is installed on the tops of the supporting columns; the top of the annular plate is provided with two sets of circular plates arranged inside and outside, four sets of flat plates arranged at equal intervals are evenly installed at the tops of the circular plates, two sets of N-shaped plates arranged front and back are installed at the bottoms of the flat plates, a power box is installed at the tops of the flat plates, and a containing box is installed on the outer wall of one side of the power box; and a multimeter is mounted on the bottom wall of the placement box. According to the invention, the electric quantity can be monitored in real time through the multimeter, so that another group of power supplies can be replaced in time, the power supply box has autonomy and is convenient to replace during replacement, the interior of the power supply box has a real-time heat dissipation function, and the power supply box is convenient to disassemble when being combined with other parts.

Description

A centralized multi-backup LED power supply for intelligent carriages and using method thereof technical field The present invention relates to the technical field of power supply, in particular to a kind of centralized multi-backup LED power supply for intelligent carriage and use thereof method. Background technique LED power is a power converter that converts the power supply into a specific voltage and current to drive LED light, usually Under normal circumstances, the input of the LED power supply includes low-voltage DC, high-voltage DC, low-voltage high-frequency AC, etc., while the output of the LED power supply is large. Most of them are constant current sources that can change the voltage with the change of the LED forward voltage drop value, while in the railway smart car, it needs to be prepared. Multiple power supplies can be replaced in time to avoid the situation of no power supply. The defect that existing LED power supply exists is: 1. The compar...
