Abstract

The invention belongs to the technical field of emergency power supplies, and particularly relates to a modular high-reliability emergency power supply capable of realizing fault diagnosis and life prediction. The modular high-reliability emergency power supply comprises a central control unit, a direct-current switching device, a battery, a plurality of battery charging modules and a plurality ofalternating-current to direct-current modules, wherein the plurality of battery charging modules are connected in parallel and then connected between the alternating current power supply and the input end of the battery; the plurality of alternating-current to direct-current modules are connected in parallel and then are connected between the alternating current power supply and the first input end of the direct current switching device. The output end of the battery is connected with the second input end of the direct current switching device; the central control unit is connected with the alternating current power supply, the direct current switching device, the battery, the battery charging module and the alternating current-to-direct current module respectively; and the output end ofthe direct current switching device is connected with a load. Alternating current-to-direct current and battery charging adopt modular design, a plurality of modules are connected in parallel, charging is not influenced by failure of a single module, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of emergency power supplies, and in particular relates to a modular high-reliability emergency power supply that can realize fault diagnosis and life prediction. Background technique [0002] With the continuous progress of society and the gradual advancement of urbanization, people's dependence on power supply is also increasing. Emergency power supply is a device that can provide short-term power supply when the normal power supply is interrupted. Its reliability and intelligence directly determine the emergency power supply situation when the normal power supply is interrupted. The biggest difference between emergency power supply and UPS and traditional power supply is that the power supply requires compulsory certification, which shows the high requirements for reliability. [0003] However, the existing emergency power supply has the problems of low system reliability and intelligence: 1. Once the AC ...
