Summary of the invention
Technical problem to be solved by this invention is that the effect by direct current cabinet and inversion are shielded combines, and provides a kind of structure simply, to be conveniently easy to a kind of DC inverter one screen operating and monitor.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of DC inverter integrated screen, comprise the DC inverter screen in left side and the storage battery screen on right side, specifically comprise the Alternating Current Unit 9 after monitoring module, batteries, rectification module, step-down adjustment unit, Direct Current Distribution Unit, voltmeter, ammeter, inverter, inversion, above various piece is installed in a set of screen.It is characterized in that, the alternating voltage ammeter repeated in script two complete equipments is united two into one, change into shared a set of by the battery pack that two overlap, Alternating Current Unit inversion fed out to be placed on below Direct Current Distribution Unit and to paste label and formed and significantly hand over the feature of straight integration and make that maintenance personnel are open-and-shut to be distinguished friendship and directly feed out unit.The interchange end of incoming cables interchange of inverter input being connected on direct current system exchanges output direct current and receives the Alternating Current Unit integrally shielded, and the input of the direct current of inverter is connected on the positive and negative terminal of batteries.If there is exchanging situation about having a power failure, battery pack can be directly utilized to feed out loop for emergency power supply without time delay to interchange.Be integrated by two kinds of equipment and decrease the use of cabinet and components and parts, utilance greatly improves.
Compared with prior art, the invention has the beneficial effects as follows:
1, have employed new cabinet body structure and arrange function, components and parts and the cabinet that effectively can save repetition, save fund for user and decrease taking of place;
Two kinds of power consumption equipments combine by the electric circuit diagram design that 2, have employed improvement, having opened up thinking, can develop new power consumption equipment integrated technique on this basis for realizing station power consumption equipment integration;
3. share a monitoring unit.Original direct current cabinet and inversion are shielded the two kinds of monitoring made respectively unite two into one, adopt a monitoring unit, attendant can inquire about and Update Table in a monitoring.

Embodiment
Below in conjunction with Figure of description, the present invention is described in detail, but it should be noted that enforcement of the present invention is not limited to following execution mode.
Existing DC power supply panel adopts two-way to exchange inlet wire automatic switchover, Alternating Current Power Supply is carried out to a charger, a floating charge motor, charger and floating charge motor charge to battery, Non-follow control charging floating charge switching device shifter switches the operating state of charger and floating charge motor, charging and floating charge motor mutually for subsequent use.Battery is powered to control is female by voltage dropping silicon chain.Determine to shield number according to the size of battery capacity, generally at least need two sides to shield body.
Existing inversion screen exchanges inlet wire switching circuit, charging module, inverter, battery by two-way, feed out switching device shifter and illumination feeds out and forms.Two-way exchanges incoming power after switching, and wherein a road powers to charging module and inversion module, and charging module charges the battery after three-phase alternating current is converted to direct current; Three-phase alternating current feeds out loop power supply directly to illumination after inverter bypass simultaneously; When exchanging dead electricity, to be reverse into after alternating current through inverter by battery and to feed out loop power supply to illumination.Due to needs by a lot of components and parts form therefore also need two sides shield body.
A kind of DC inversion integrated screen of the present invention, in system, each data and state are gathered by each collecting unit, and give main monitoring by RS485 communication uploading data, after carrying out data analysis by main monitoring, control system is in charged state, floating charge state, fault-alarming state, cell activation state or emergency lighting state.
The operation principle of integrated screen of the present invention: input terminal in the interchange incoming power access screen of Liang Ge transformer station, rectification module 3 powers on, and has voltmeter 6 to export.Connection charge switch charges the battery and closing bus bar is powered.Inversion module receive simultaneously AC power inversion module carry out self-inspection find AC power be that interchange feeds out loop power supply.When AC power has a power failure, battery will be powered to control mother, conjunction mother and inversion module without time delay, make it keep non-stop run state.Work as system malfunctions, supervising device will be reported to the police, and fault can be inquired about on a display screen.
Exchange the ac output end sub-connection feeding out loop and inversion module; The direct-flow input end sub-connection of batteries 2 and inverter 8; Rectification module 3, batteries 2 are connected with Direct Current Distribution Unit 5; Voltmeter 6, ammeter 7 are connected with rectification module 3; Exchange the ac input end sub-connection of input terminal and inversion module 3.
The present invention has the following advantages:
Adopt function element modularized design, and can charged hot plug, this just brings facility to the breakdown maintenance of integrated screen, when one of them functional module fault, can not the work of other elements of influential system, and can the direct each element of charged for replacement.Like this, the failture evacuation difficulty of integrated screen declines, and troubleshooting time shortens, and can avoid failure propagation.
The inverter that integrated screen of the present invention adopts is inversion module, and inversion module can multiple parallel connection, can carry out System Expansion easily.The direct voltage that inversion module requires simultaneously is 220V, therefore, can share a set of battery with direct current component, the electric substation's initial investment cost greatly reduced and maintenance cost.In addition, after adopting integral structure, the communication interface RS485 of inverter can be connected to main supervising device or direct and upper machine communication.After supervising device, the intellectuality of system improves, and system is in automatic control state at ordinary times, and can with upper machine communication, complete " four is distant " function of remote measurement, remote signalling, remote control, remote regulating.Greatly reduce the maintenance workload of operations staff.
Integrated screen exchanges switching circuit original two covers and is merged into a set of interchange switching circuit, decreases Graded coordination; Also original two cover batteries are merged and share a set of battery, greatly reduce electric substation's initial investment cost and change the environmental pollution that brings of battery and have also been obtained effective control; Original two cover supervising device functions are merged, and share a set of supervising device, control system is more unified, facilitates man-machine communication and operations staff to safeguard.And greatly provide cost savings.
