Novel DC power supply system

Abstract

A novel DC power supply system relates to the technical field of a DC system power supply pack screen cabinet. The novel DC power supply system is characterized in that the novel DC power supply system comprises an AC power distribution unit, a charging unit, a lead acid storage battery, a voltage reduction unit, a switch and an output unit. The AC power distribution unit, the charging unit, the lead acid storage battery, the switch and the output unit are connected in series in sequence; and the voltage reduction unit is connected in parallel with the lead acid storage battery. The charging unit comprises a first charging unit, a second charging unit, a third charging unit and a fourth charging unit, wherein the charging units are connected in parallel with each other. The lead acid storage battery comprises a first lead acid storage battery, a second lead acid storage battery, a third lead acid storage battery and a fourth lead acid storage battery, wherein the lead acid storage batteries are connected in parallel with each other. The novel DC power supply system is simple in structure and can provide a DC power supply which is high in anti-interference performance.

Description

technical field [0001] The invention relates to the technical field of DC system power supply panel cabinets, in particular to a novel DC power supply system. Background technique [0002] In recent years, the degree of automation of electrical equipment has become higher and higher. At the same time, the requirements for the operation accuracy and response time of the equipment have become higher and higher, that is, there are higher requirements for the control power supply of the equipment. The AC power supply control operation circuit has been eliminated and began to use The main advantage of the DC system power supply is that the DC power has strong anti-interference ability. The AC power may have unstable waveforms, spikes, and jitters in a complete cycle. It cannot meet the requirements of high-precision control equipment, which may cause equipment malfunctions, or Delayed action will cause equipment failure and more likely cause personal safety accidents.
