Description
Technical field
The present invention relates to the technical fields of battery protection, are specifically a kind of emergency power supply storage battery under-voltage protection circuit.
Background technology
With the development of society, the continuous improvement of Building technology level, the building in city is intended on a large scale, high stratification hair
Exhibition higher and higher to the power reguirements of building, social informationization thereupon, the modernization of building, make building to power supply according to
Rely also increasing, especially some important public buildings, once interruption of power supply, will cause great political impact or economy
Loss, if fire occurs, consequence is just more hardly imaginable.
Emergency power supply plays a big part after mains-supplied interruption, and emergency power supply includes charger, inverter, electric power storage
Pond, isolating transformer can use DC inverter for load into alternating current, however emergency power supply is in emergency, meeting
The electric energy of battery consumption, when the voltage of accumulator reaches under-voltage value DC180V, inverter can be automatically stopped work, and protection stores
Battery, but at the same time, also in continual work, accumulator will also power control panel to control panel, at this point, accumulator is just
In deep discharge process, accumulator plate can be caused to be acidified, so as to reduce the normal service life of accumulator.
The content of the invention
A kind of emergency power supply storage battery under-voltage protection circuit provided by the invention, solves emergency power supply accumulator and is using
During due to the damage problem of accumulator caused by under-voltage.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of emergency power supply storage battery under-voltage protects circuit, including charger, control panel, accumulator, force knob SK2,
Relay J4, diode FD1, diode FD2；
The charger connects the anode of the diode FD1 and the diode FD2 respectively, the diode FD1's
Cathode is connected with the power supply of the control panel, and the cathode of the diode FD2 passes through the relay J4 and the control panel
Power supply connects, and the accumulator is connected with the pressure knob SK2, and the pressure knob SK2 is connected in parallel on the relay J4's
Both ends.
When alternating current is normal, the charger is powered through the diode FD1 to the control panel.
When the voltage drop of the accumulator is down to DC180V, reach under-voltage value, the pressure knob SK2 is disconnected, the storage
Battery continues to power to control panel by the relay J4, when the voltage of the accumulator is down to overvoltage/undervoltage, in program board
DSP send signal the relay J4 controlled to disconnect, the control panel is stopped, and reaches the under-voltage guarantor to the accumulator
Shield.
Beneficial effects of the present invention：The present invention controls the break-make of relay by control panel, realizes emergency power supply accumulator
Under-voltage protection, be not only simple in structure, be at low cost, and the service life of accumulator can be extended.
Description of the drawings
In order to facilitate the understanding of those skilled in the art, the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 protects circuit diagram for a kind of emergency power supply storage battery under-voltage of the present invention.
Specific embodiment
A kind of emergency power supply storage battery under-voltage protects circuit, as shown in Figure 1, including charger, control panel, accumulator, by force
Knob SK2 processed, relay J4, diode FD1, diode FD2.
Charger connects the anode of diode FD1 and diode FD2, the cathode of diode FD1 and the electricity of control panel respectively
Source connects, and the cathode of diode FD2 is connected by the power supply of relay J4 and control panel, and accumulator is connected with pressure knob SK2,
Knob SK2 is forced to be connected in parallel on the both ends of relay J4.
Wherein, charger is when alternating current is normal, for powering to control panel；
Wherein, accumulator is in emergency, for powering to control panel.
Wherein, control panel includes transformer, relay, program board, sample circuit, and control panel is gathered by sample circuit to be stored
Information of voltage on battery, and through the DSP processing in program board, and then opening or breaking for relay J4 can be controlled.
Wherein, knob SK2 is forced, is connected with accumulator, presses and forces knob SK2, into emergency rating, accumulator passes through
Knob is forced to be powered to control panel.
When alternating current is normal, charger is powered through diode FD1 to control panel, when alternating current power-off or charger damage,
It is manually pressed by forcing knob SK2, accumulator is same knob SK2 is forced to press down through knob SK2 is forced to power to control panel
When, relay J4 is closed, and when the voltage drop of accumulator is down to DC180V, accumulator reaches under-voltage value, and knob SK2 is forced to disconnect,
Since control panel is also working on, accumulator can continue to power to control panel by relay J4 so that the electricity of accumulator
Continue to consume, reach the state of accumulator overvoltage/undervoltage.Acquisition Circuit in this process, control panel can gather accumulator at the moment
Information of voltage, when the voltage of accumulator is down to overvoltage/undervoltage, the DSP in program board can send signal control relay J4 disconnections,
So as to be that control panel is stopped, reach the under-voltage protection to accumulator.
More than content is only to design example and explanation of the invention, affiliated those skilled in the art
Various modifications or additions are done to described specific embodiment or are substituted in a similar way, without departing from invention
Design or surmount scope defined in the claims, be within the scope of protection of the invention.
