Description
Technical field
The utility model belongs to the small-power uninterrupted power supply in the transformer station, is specifically related to a kind of two-way direct current output uninterrupted power supply of charged pool management.
Background technology
Along with the continuous development of power industry, in some small-sized transformer stations or the small-sized box type transformer station, the small-power uninterrupted power supply demand that charged pool is patrolled and examined constantly increases.In the power technology field, the mode that solves this type demand mainly contains two kinds at present: a kind of is to adopt small-sized electric power operation DC power supply, and another kind is to adopt the UPS power supply.But there is following defective in this dual mode: small-sized electric power operation DC power supply is too huge; Ups power belongs to the business level product, does not fit into the demand of power industry technical grade, and ups power do not have the battery management function, has a strong impact on the useful life of battery.
Summary of the invention
In order to solve the problems referred to above that the prior art field exists; The purpose of the utility model is; A kind of two-way direct current output uninterrupted power supply of charged pool management is provided; It is too huge to solve existing small-sized electric power operation DC power supply, and ups power does not have the battery management function, has a strong impact on the problem in the useful life of battery.
The two-way direct current output uninterrupted power supply of the charged pool management that the utility model provides; It comprises external ac power source, first rectification filtering module, second rectification filtering module, exports intelligent handover module, battery management module, boost module, Voltage stabilizing module, CPU control module; The input termination external communication input 1 of said first rectification filtering module; Its output is connected with the input of the intelligent handover module of output, and the output of exporting intelligent handover module is connected with power consumption equipment, the input termination external communication input 2 of said second rectification filtering module; Its output is connected with the input of Voltage stabilizing module; The output of said Voltage stabilizing module is connected with input, the power consumption equipment of the intelligent handover module of output respectively, and the input of said boost module is connected with battery management module, and its output is connected with the input of Voltage stabilizing module; Said external communication input 2 is connected with storage battery through battery management module, and the CPU control module is passed through circuit and is connected with above-mentioned all modules.
The two-way direct current output uninterrupted power supply of the charged pool management that the utility model provides, its beneficial effect are that this power supply is a two-way direct current output uninterrupted power supply; Integrated level is high, and volume is little, exchanges input and imports stepless switching with powered battery; Have the battery management function; Can realize the equal floating charge conversion of battery automatically, regularly battery carried out activation, prolong the useful life of battery.
