Description
Technical field
The utility model relates to charging device technical field, is specifically related to a kind of auto-breaking quick charger.
Background technology
Current, the user having electro-tricycle and electric household automobile is many especially, and charging battery jar is absolutely necessary key component, but the quick charger of existing commercially all simple types does not all have storage battery to be full of the function of auto-breaking after electricity.Charging can be continued after current quick charger is full of electricity, can only manually power-off, when be full of electricity constantly conductance cause that to reconcile charging current gear incorrect, not low to the damage ratio of storage battery, storage battery scraps that rear discharged acid pickle is current also cannot well be processed, and can cause larger infringement to environment.There is the charger of some frequency conversions or microcomputer-controlled in the market, during the charging of these chargers, floating charge state can be entered when being about to be full of, effectively storage battery can be protected under floating charge state, but for the product of this heavy-current discharge of motor vehicle, add that the mileage of the many races of the electricity of floating charge is very limited, moreover storage battery can only cut off the charge power supply of storage battery after being full of when charging, the own power source of charger can not be cut off, that is this kind of charger is all that storage battery is filled with, broken electricity, charger is still always in stand-by operation (except non-manual power-off), and this kind of charger is expensive, market receptance is lower.
Utility model content
The utility model provides a kind of auto-breaking quick charger, overcharges damage storage battery and the high problem of production cost with what solve that prior art exists.
The utility model solves the technical scheme that its technical problem adopts:
A kind of auto-breaking quick charger, comprise housing, housing arranges ammeter, power initiation push-button switch, fast charge switch at a slow speed, ventilating fan, D. C. output plug line, power input plug line and grounding terminal, the built-in annular shaped charge transformer of housing, charging rectifier bridge, current transformer and circuit board, circuit board is arranged current rectifying and wave filtering circuit and control relay, current transformer and current rectifying and wave filtering circuit form auto-breaking unit, power initiation push-button switch is connected with circuit board with current transformer respectively with power input plug line, auto-breaking unit and annular shaped charge transformer, charging rectifier bridge series connection after again with ammeter, fast charge switch at a slow speed, ventilating fan, D. C. output plug line is connected, charging rectifier bridge, current transformer, electric capacity and relay composition control circuit unit, the input of charging rectifier bridge is connected in the secondary coil two ends of current transformer in parallel, and the output both positive and negative polarity of charging rectifier bridge is in parallel with the positive and negative terminal of electric capacity and the actuating coil of relay respectively.
Above-mentioned housing is arranged handle-concealed and insurance.
Above-mentioned power initiation push-button switch is double-throw duplex reset button switch.
Above-mentioned fast charge switch is at a slow speed for singly to throw duplex rocker type switch.
Above-mentioned current transformer is F type silicon steel sheet core instrument transformer or ferrite bead instrument transformer.
Operation principle of the present utility model is: first charger and storage battery must be linked together, during circuit start, press power initiation push-button switch, charger is started working, when 220V alternating current passes through the primary coil of the current transformer of auto-breaking unit simultaneously, a low-voltage ac voltage is produced at secondary coil, the actuating coil of relay is supplied after rectifying and wave-filtering, make relay power adhesive, connect normally opened contact, after unclamping power initiation push-button switch, due to normally opened contact self-locking, charging part gets electricity, when charger starts to charge, charging current is very large, after relay adhesive, the voltage at actuating coil two ends remains on direct current about 6V, when storage battery is close to when being full of, charging current diminishes, the voltage that the actuating coil of relay obtains also diminishes, when storage battery is full of, charging current continues to diminish, the voltage that the actuating coil of relay obtains continues to diminish until can not adhesive, at this moment relay normally open contact disconnects, thus cut off the input power of charger, storage battery charging is terminated.
Mutual matching effect between the electric current that the utility model utilizes current transformer and load to work; reach power-off object; while storage battery do not overcharged in protection, it also avoid charger and to work long hours caused infringement, there is the advantage that structure is simple, reliable and stable and cost is low.
