Description
Technical field
The present invention relates to the technical field of battery protection, specifically a kind of emergency power supply storage battery under-voltage protection
Circuit.
Background technology
Along with the development of society, improving constantly of Building technology level, the building in city trends towards on a large scale,
High stratification development is more and more higher to the power reguirements of building thereupon, the informationization of society, the modern times of building
Changing, make building the most increasing to the dependence of power supply, especially some important public buildings, once interrupt
Power supply, will result in great political fallout or economic loss, if breaking out of fire, consequence the most more can't bear to set
Think.
Emergency power supply is had no progeny in mains-supplied and is played a big part, emergency power supply include charger, inverter,
Accumulator, isolating transformer, it is possible to become alternating current for load, but emergency power supply DC inverter
When emergency, the electric energy of meeting battery consumption, when the voltage of accumulator reaches under-voltage value DC180V,
Inverter can be automatically stopped work, protects accumulator, but meanwhile, panel is also in continual work
Making, accumulator also to be powered to panel, and now, accumulator is at deep discharge process, can cause storage
Battery pole plates is acidified, thus reduces the normal service life of accumulator.
Summary of the invention

Accompanying drawing explanation
For the ease of it will be appreciated by those skilled in the art that the present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is one emergency power supply storage battery under-voltage protection circuit figure of the present invention.
Detailed description of the invention
A kind of emergency power supply storage battery under-voltage protection circuit, as it is shown in figure 1, include charger, panel,
Accumulator, pressure knob SK2, relay J 4, diode FD1, diode FD2.
Charger connects diode FD1 and the anode of diode FD2, the negative electrode of diode FD1 and control respectively
The power supply of making sheet connects, and the negative electrode of diode FD2 is connected with the power supply of panel by connecting relay J 4,
Accumulator is connected with forcing knob SK2, forces knob SK2 to be connected in parallel on the two ends of relay J 4.
Wherein, charger is when civil power is normal, for powering to panel；
Wherein, accumulator is when emergency, for powering to panel.
Wherein, panel includes transformator, relay, program board, sample circuit, and panel is by sampling
Circuit gathers the information of voltage in accumulator, and the DSP process in program board, and then can control relay
J4 opens or disconnected.
Wherein, force knob SK2, be connected with accumulator, press pressure knob SK2, enter emergency rating,
Accumulator is powered to panel by forcing knob.
When civil power is normal, charger is powered to panel through diode FD1, when civil power power-off or charger
During damage, being manually pressed by forcing knob SK2, accumulator, through forcing knob SK2 to power to panel, is being forced
While knob SK2 presses down, relay J 4 closes, when the voltage drop as little as DC180V of accumulator, electric power storage
Pond reaches under-voltage value, forces knob SK2 to disconnect, and owing to panel is also working on, accumulator can be passed through
Relay J 4 continues to power to panel so that the electricity of accumulator continues to consume, and reaches accumulator overvoltage/undervoltage
State.In this process, the Acquisition Circuit in panel can gather the information of voltage of accumulator the moment, work as storage
When the voltage of battery is down to overvoltage/undervoltage, the DSP in program board can send signal control relay J4 and disconnect, from
But panel quits work, reach the under-voltage protection to accumulator.
Above content is only the design example to the present invention and explanation, the skill of affiliated the art
Described specific embodiment is made various amendment or supplements or use similar mode to replace by art personnel
In generation, without departing from the design of invention or surmount scope defined in the claims, this all should be belonged to
The protection domain of invention.
