The invention discloses a cabinet power supply system, a power supply switching control method and a cabinet. The cabinet power supply system comprises a switching module, detection modules, a control module, a high-voltage conversion module, an energy storage module and a low-voltage conversion module, wherein each input end of the switching module is connected with a corresponding detection module; the control module is connected with the detection modules and controls operation of the switching module according to information detected by the detection module; the input end of the low-voltage conversion module is connected with the output end of the high-voltage conversion module and converts voltage output by the high-voltage conversion module into working voltage suitable for all devices on a circuit board load; the switching module and the detection modules are positioned at the input end of the cabinet; the control module, the high-voltage conversion module, the energy storage module and the low-voltage conversion module are positioned in the cabinet. According to the cabinet power supply system, the stability of operation of all the elements of the cabinet is improved.
Description
Technical field [0001] The present invention relates to the technical field of power supplies, in particular to a cabinet power supply system, a power switching control method and a cabinet. Background technique [0002] As we all know, the communication system cabinet often adopts dual power supply design to provide power redundancy protection function. The usual practice is to connect the cabinet to two power sources: one AC power source and one DC power source, or two AC power sources. However, no matter what kind of power supply mode, there is a short-term power failure when switching. Due to the sudden power failure, it is easy to damage the components, resulting in poor stability of the work of the components. Summary of the invention [0003] The main purpose of the present invention is to provide a cabinet power supply system, which aims to improve the stability of the operation of each element of the cabinet. [0004] In order to achieve the above objective, the present i...
