Description
Technical field
The utility model belongs to technical field of electric equipment, particularly a kind of electric power DC operation power source system.
Background technology
Electric power DC operation power source system is the operating power of transformer station as control, signal, relaying protection, is also emergency power supply and the emergency lighting power supply of visual plant.Monitor and safeguard that the safe and reliable operation of the integrity of DC equipment to transformer station and whole electric power system is very important.
Storage battery is the important component part of electric power DC operation power source system; when Alternating Current Power Supply interrupts; storage battery provides reliable protection power source, on/off switch power supply; when electric power system is broken down; protective device just can send guard signal in time; disengagement failure circuit, ensures the safe operation of electric power system, so the quality of battery service is directly connected to the safe operation of electric power system.In battery operation, large multi-state is that low discharging current uses, and charges, so only fills and put less, only fill and do not put, make storage battery generally have the existence of " sulfuration " phenomenon, reduce battery capacity when all filling by larger current.Therefore, electric power DC operation power source system regulation quarterly will once activate in the property checked discharge and recharge, solves " sulfuration " problem.Will disconnect cell switch when carrying out activation act, battery pack and charging module be thrown off, and connects load at battery pack two ends, one time activation experiments takes two day time, and the operating time is long, and manual operation intensity is large.During activation experiments, storage battery is that detachment system runs, if but now AC interruptions, direct current system can not provide operating power, brings harm to the operation of transformer station.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of electric power DC operation power source system that can activate storage battery and can not bring harm to the operation of transformer station.
For this reason, the technical solution of the utility model is: a kind of electric power DC operation power source system, comprises rectification module, batteries and reserve battery, and described rectification module input connects external communication electricity, and output connects DC bus; Described batteries is made up of multiple battery module, and each battery module series connection is on DC bus; It is characterized in that: also comprise cell activation module, cell activation module is made up of control unit, cell activation functional unit, boost function unit and step-down charge function unit; Described cell activation module is connected on DC bus, and reserve battery is connected in cell activation module.
When the utility model normally works, rectification module provides working power on the one hand the DC load of transformer station, and accumulators group charging on the other hand, reserve battery is also operated in charge mode.When external ac power source disappears, DC load, by storage battery power supply, ensures transforming plant DC load supplying continuity.When external ac power source disappears, and batteries is when also breaking down, the boost function module of cell activation module can convert reserve battery 12V direct voltage to 220V direct voltage, powers to the DC load of transformer station, thus ensures the continuity of operating power.The utility model utilizes the boost function unit of cell activation module to convert the 12V direct voltage of reserve battery to 220V direct voltage, to transforming plant DC load supplying; And external dc 220V voltage can be reduced to 12V voltage by step-down charge function unit, for charging to reserve battery; Cell activation functional unit, then for activating batteries and reserve battery, prevents battery from occurring sulfuration problem.
Accompanying drawing explanation
Be described in further details below in conjunction with accompanying drawing and execution mode of the present utility model.
Fig. 1 is principle schematic of the present utility model.
Embodiment
See accompanying drawing.The present embodiment comprises rectification module 1, batteries 2 and reserve battery 3, and described rectification module 1 input connects external communication electricity 4, and output connects DC bus 5; Described batteries 2 is made up of multiple battery module, and each battery module series connection is on DC bus 5; Also comprise cell activation module 6, cell activation module 6 is made up of control unit, cell activation functional unit, boost function unit and step-down charge function unit; Described cell activation module 6 is connected on DC bus 5, and reserve battery 3 is connected in cell activation module 6.
Battery module in the batteries 2 of the present embodiment and reserve battery 3 include storage battery, control switch and binding post, connected storage battery can be made to enter different operating state by the difference of control switch upper terminal.
The present embodiment is by the multiple battery module series connections in batteries 2 on DC bus, and rectification module 1 is to its charging, and simultaneously outside has during Large Copacity impact load and powered by batteries 2; Reserve battery 3 is also operated in charge mode, and voltage is become 12V by the step-down charhing unit of cell activation module 6 by direct current 220V voltage, charges to reserve battery.
Storage battery is in normal work, and will activate at set intervals, when carrying out activation act, the both positive and negative polarity that need activate single battery module connects with the both positive and negative polarity of cell activation functional unit in cell activation module 6 respectively; The both positive and negative polarity of reserve battery 3 connects DC bus 5, and the cell activation functional unit of cell activation module starts activation work.Be now to be connected in cell activation module 6 by the interface of cell activation functional unit by active cell, cell activation module activates it.To cell activation simultaneously, normally run for not affecting direct current system, reserve battery 3 is sealed in battery pack.
Direct current system duration of work, when reserve battery 3 needs to activate, the both positive and negative polarity of reserve battery 3 connects with the both positive and negative polarity of cell activation functional unit in cell activation module 6 respectively; The cell activation functional unit of cell activation module 6 starts activation work.Be now to be connected in cell activation module 6 by the interface of cell activation functional unit by reserve battery 3, cell activation module 6 activates it.
Direct current system duration of work, when external ac power source 4 occurring and disappearing, DC load is powered by batteries 2, ensures transforming plant DC load supplying continuity.When batteries also breaks down simultaneously, the both positive and negative polarity of reserve battery 3 is connected with the both positive and negative polarity of boost function unit in cell activation module 6 respectively, control unit starts boost function cell operation, the voltage of reserve battery 3 raises as direct current 220V from direct current 12V by cell activation module 6, power to external loading, ensure the continuity of operating power.
The wiring of the storage battery in the present embodiment in batteries 2 and reserve battery 3, control switch, binding post, and the wiring of various standard interface all completes in factory, when direct current system is installed at the scene, only each battery module need be put on a mounting board as requested, by standard interface and each module wiring terminal grafting, just can the wiring of completion system, the whole wiring course of work, time is short, easy to operate, safety.When certain battery module needs to change, only it need be connected with standard interface and unplug, just can realize the replacing of battery module.
