Abstract

The invention provides a tunnel redundant DC power supply system and a power supply method. The power includes a parallel DC power supply rectifier device, a wire inlet end of the DC power supply rectifier device is connected to an AC bus, a wire outlet end of the DC power supply rectifier device is connected to a DC busbar, the DC power supply rectifier device rectifies 380V AC power into 400V high-voltage DC power, the DC busbar supplies power to an LED lamp, and the LED lamp includes a DC / DC power supply and an LED lamp. According to a minimum system of the invention, an AC / DC rectifies the380V AC power into the 400V high-voltage DC power. An AC lightning arrester function is lightning protection grounding, and a circuit is protected, an AC contactor is responsible for controlling thestarting and stopping of the device, and the emergency lighting of a first-level load can be satisfied.

Description

technical field [0001] The present disclosure relates to the technical field of power supply, in particular to a tunnel redundant DC power supply system and a power supply method. Background technique [0002] At present, tunnel lighting still adopts the traditional AC power distribution mode in the power distribution link, that is, each LED lamp is equipped with an AC-DC power module to drive the LED light source. [0003] There are two shortcomings in the above power distribution method. One is that the life of the AC-DC power supply module cannot keep up with the life of the LED light source. During the life cycle of the LED light source, the power supply is generally replaced two to three times; the other is the loss of power distribution lines. very big. [0004] At the same time, the transformer of the power supply system is the key link of the power supply system and the heart of the tunnel power supply. Once the transformer is damaged, the power supply system will b...
