Description
Technical field
The utility model relates to a kind of portable emergency supply unit adopting ferric phosphate lithium cell.
Background technology
Transformer station existing direct current emergency power supply adopts some joint 12V/100Ah(weight to be about 31Kg) lead acid accumulator forms the direct current system of corresponding 220/110V, in order to fast removal, be unified into a unit by 3 joint 12V/100Ah battery strings, form the system of corresponding 220/110V at the scene with 6/3 unit.According to the characteristic of lead acid accumulator, emergency power supply battery pack needs to carry out charge maintenance with charger at ordinary times, and to prevent the self discharge of battery, the minimizing of capacity, needs core appearance maintenance of manually discharging time necessary, to play corresponding effect in emergent occasion.But there is a lot of problem in existing plumbic acid emergency cell: 1) existing emergency power system series-connected cell quantity is many, whole system carrying inconvenience; 2) emergency power supply battery charging management is safeguarded inconvenient, needs the special charger of extra connection to carry out charge maintenance; 3) number of batteries is many, and floor space is larger; 4) there is pollution problem in the valve control closed lead acid accumulator that emergency power system uses; 5) existing emergency power system valve control closed lead acid accumulator needs regular replenishment, discharge and recharge, and maintenance workload is large.
Summary of the invention
For above the deficiencies in the prior art, the utility model provides a kind of portable emergency supply unit adopting ferric phosphate lithium cell.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable emergency supply unit adopting ferric phosphate lithium cell, this device comprises module cabinet and Battery case, described module cabinet comprises AC input cell, charging module group, monitoring unit and accordingly battery management module and boost module group, described Battery case comprises and ferric phosphate lithium cell, described AC input cell is connected with boost module group by charging module group, described charging module group and described monitoring unit and corresponding battery management module and ferric phosphate lithium cell model calling.
Described charging module group at least comprises three charging modules.
Described boost module group at least comprises two boost modules.
The external 380V alternating current of described AC input cell.
The utility model has the advantage of:
This device adopts parallel technology and ferric phosphate lithium cell configuration, changes the type of traditional battery and the connection type of system, overcomes present emergency power system number of batteries many, wiring is complicated, Heavy Weight is inconvenient to move, and floor space is excessive, increases the defect such as maintenance workload at ordinary times; Increasing boost module by changing connection type, decreasing the quantity of the series connection of battery, reducing battery floor space, make emergency power supply safer, more reliably, more stable; Use ferric phosphate lithium cell, reduce self-discharge of battery, reduce maintenance workload at ordinary times, substantially increase operating efficiency; The use of ferric phosphate lithium cell alleviates the weight of battery, and fast and easy moves, carry, and alleviates labour intensity; Ferric phosphate lithium cell does not pollute, and instead of conventional lead acid or ickel-cadmium cell configuration, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1: the utility model structure principle chart.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.This device comprises module cabinet and Battery case, described module cabinet comprises AC input cell, charging module group, monitoring unit and accordingly battery management module and boost module group, described Battery case comprises and ferric phosphate lithium cell, described AC input cell is connected with boost module by charging module, described charging module and described monitoring unit and corresponding battery management module and ferric phosphate lithium cell model calling.
As shown in Figure 1, in device, AC input cell 10 is circumscribed with three-phase alternating current input, one end of AC input cell is connected with charging module group, be connected with charging module group for boost module group, the 48V ferric phosphate lithium cell module 12 in addition connected to charging module 11 and monitoring unit and corresponding battery management module 14.
In the present embodiment, charging module group comprises three charging modules 11, and boost module group can be the boost module 13 of more than 2.AC input cell 10 connects outside three-phase alternating current, and alternating current unit connects with the input of charging module 11 simultaneously, and the output of charging module 11 is connected with energy-storage battery unit 48V ferric phosphate lithium cell and boost module 13.
When exchanging input and being normal, alternating current gives charging module 11 for alternating current by AC input cell 10, alternating voltage is transformed into direct current 48V by charging module 11, accumulators group 12 is charged on the one hand, power supply is to boost module 13 on the other hand, direct voltage 48V is changed into high direct voltage 220V/110V and exports by boost module 13, feeds out switch 18 to external dc load bussed supply by direct current.
When exchanging input dead electricity; charging module 11 quits work without interchange input; ferric phosphate lithium cell group 12 powers to boost module 13; boost module uninterruptedly exports high pressure 220V/110V; to externally fed, when ferric phosphate lithium cell group 12 discharges the final voltage arriving battery, for protection ferric phosphate lithium cell group 12 is damaged because of deep discharge; module stops exporting automatically, and reports monitoring unit.Monitoring unit is monitored battery voltage information, and when cell voltage arrives the set point of monitoring, monitoring unit issues the order that quits work to boost module, and boost module quits work, to prevent battery pack overdischarge.
Ferric phosphate lithium cell group 12 is made up of the ferric phosphate lithium cell of two groups of 24V, and two Battery packs are installed in metal box, and two Battery pack serial connections form the energy storage section of direct current 48V as system.
The composition such as charging module, boost module, alternating current unit power cabinet, two Battery packs are installed on battery case respectively, and battery case, by cable and power cabinet rapid-assembling, forms emergency power system.Bottom power cabinet and battery case, castor is housed, convenient on-the-spot mobile.Whole system is divided into 3 parts, and power supply cabinet is no more than 50kg, and battery case can be split into 2 unit, and each unit is no more than 50kg, and battery case, power cabinet be not all higher than 800mm, and fast and easy is carried, easy to carry.
Should be appreciated that above is illustrative and not restrictive by preferred embodiment to the detailed description that the technical solution of the utility model is carried out.Those of ordinary skill in the art can modify to the technical scheme described in each embodiment on the basis of reading this utility model specification, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
