A kind of fire-fighting emergent multifunctional power system
Technical field
The present invention relates to emergency service technical field, is specifically related to a kind of fire-fighting emergent multifunctional power system.
Background technology
Fire emergency lampses dedicated emergency power-supply system is the generation condition of a fire or other in emergency circumstances indispensable in building
The power supplys such as few identification light, illuminating lamp.Improved as building's fire is horizontal, the especially increase of high-rise, answer urgent telegram
There is development at full speed in source.
The fire emergency lampses dedicated emergency power-supply system used at present in building is all largely self-powered independence
Type fire emergency and evacuation indication system, power-supply battery restricted lifetime, generally 2 to three years, with the increasing of usage time
Long, the capacity of battery is gradually reduced, or even failure.In addition, in order to ensure the normal work of battery, fire emergency lighting power supply one
As all provide manual detection function, it is necessary to manually be checked one by one, it is time consuming, moreover, the expense for changing battery occupy it is high not
Under, therefore, failure can not usually be found and exclusion in time by timely.Once generation disaster, illumination can not with evacuation indication system
Normal work, or illumination duration do not reach defined standard, and hidden trouble is brought to evacuating personnel and disaster relief work.Also
It is to say, there is can not detect power supply status in real time and find asking for failure for current fire emergency lampses dedicated emergency power supply
Topic, the shortcomings that causing that normal use can not be ensured in Emergency use, can not meet being actually needed for fire-fighting emergent, there is one
Fixed potential safety hazard.
The content of the invention
Present invention solves the technical problem that it is to provide the high fire-fighting emergent multifunctional power system of a kind of function admirable, reliability
System, not only with output short circuit protection, overload, overheat protector and battery over-discharge protection function, also sound fault alarm,
And fault type is indicated, and it is simple to operate, it is easy to maintenance.
In order to solve the above technical problems, the technical solution adopted in the present invention is:
A kind of fire-fighting emergent multifunctional power system, mainly includes:LCD liquid crystal displays, LCD show menu switch key,
Branch road output breaker, it is main electricity input breaker, battery pack positive/negative input breaker, force emergency starting switch, start/
SR, manual/auto button, PE line banks, output neutral conductor line bank;
Described fire-fighting emergent multifunctional power system, its installation method are:
Step 1: civil power inputs:It is directly connected at city's power source head;
Step 2: body left-hand door is opened, breaker backplate screw is unloaded;Open the right door of body, you can see branch road
Export the position of breaker, main electricity input breaker, battery pack positive/negative input breaker and the inlet-outlet line from bottom right side;
After first input, out-put supply line are penetrated by the position of the inlet-outlet line of bottom right side, then along middle standing pillar position input power
The live wire of line connects " L " end by sign, and ground wire is connected to PE line banks;After disengaging power line connects, then batteries are installed, battery
The positive pole of group connects the "+" end of branch road output breaker, and negative pole connects the "-" end of branch road output breaker;The live wire of power line and zero
Line please don't be reversed, when connecing electricity, please don't livewire work, avoid electric shock accidents;
Step 3: battery inputs:Series battery rated voltage is 192V, battery positive and negative electrode be sure not it is reversed, according to electric discharge
Electric current carries out selecting battery connecting line, and the positive pole of battery pack connects battery pack positive/negative input breaker, and the negative pole of battery pack connects
Line terminals, connection should be stayed at one, first connect the positive and negative electrode of battery, determine to reconnect after wiring is errorless at last battery pack it
Between line;
Step 4: battery altering:It is defeated first to disconnect main electricity input breaker, battery pack positive/negative input breaker and branch road
Go out breaker;Disconnect any one end line of series battery;Disconnect battery pack to battery pack positive/negative and input breaker line,
And wrap joint with insulating tape;The capacity of battery should carry out selection installation in accordance with table three;

During start, first disconnected branches export breaker, close main electricity input breaker, battery pack positive/negative input breaker, by opening
During dynamic/SR, LCD liquid crystal displays are shown and indicate to export branch-path failure, and buzzing is alarmed;Dish is shown by LCD
Single switch key, all branch trouble promptings are shown, then close branch road output breaker;Fault alarm recovers normal after disappearing, then
Menu switch key is shown by LCD, LCD liquid crystal displays show main piezoelectric voltage, cell voltage, output voltage respectively;When cut-out city
When electric, that is, emergency service is transferred to, LCD liquid crystal displays show load current, output voltage and cell voltage respectively;When in hand
" manual " position, as emergency service state are selected on dynamic/automatic button, selects " automatic " position, emergency power supply recovers master
Electricity power supply;Show that menu switch key can carry out checking the display of LCD liquid crystal displays by LCD;
When civil power is normal, emergency power supply output provides for civil power, while charger charges to battery;When civil power stops
Or during less than below 180V, emergency power supply is operated under emergency rating.
Further, the LCD liquid crystal displays can show main piezoelectric voltage, output load current, cell voltage, output
Voltage, fault type.
Further, when faulty, this emergency power system carries out audible alarm, can show menu switch key by LCD
Audible alarm is eliminated, and fault type can be checked, is easy to fix a breakdown in time;If failure is not excluded for, it is impossible to other guide is consulted,
If have new failure, buzzer pipes alarm again.
Further, emergency power system works as battery powered, loads as 120%, emergency power supply normal work, load exceedes
When 120%, automatic protection after 10s, load can be protected completely, ensure normal work when having a power failure.
Further, the power-supply system allows to connect resistive, perceptual, capacitive load various light fixtures;Resistive load light fixture
Total capacity is equal to the general power of power supply, capacitive, inductive load light fixture total capacity be equal to power supply general power be multiplied by the power of load because
Number.
Further, the power-supply system is mainly used in the public building that personnel are numerous, intensive, high-rise public building or
Hypogee etc..
Points for attention:
1st, " force emergency starting mode " and provide electric energy by battery, be operated in emergency service state." automated manner " and " hand
Flowing mode " emergency power supply is protected to battery over-discharge, forces emergency starting mode not controlled by automatic, manual switch.
If the 2, battery deposits more than 3 months when not in use, please charge more than 20 hours, to keep battery electric quantity abundance to prolong
Long battery.
3rd, main electricity was not stopped more than 3 months, it is necessary to discharged, to ensure battery pack energy reliably working.
The beneficial effects of the invention are as follows:Load can be protected completely, ensure normal work when having a power failure;Using MICROCOMPUTER PROCESSING
Device controls, and uses SPWM modulation techniques, and performance is more excellent, and reliability is high;Its control panel is LCD liquid crystal displays, can
