Description
Technical field
The utility model relates to a kind of easy Storage battery protecting device.
Background technology
In all power supply occasions, storage battery is all indispensable equipment, in the use occasion of particularly EPS, the most important thing of storage battery system cloud gray model especially, but, that causes due to the improper use of storage battery or Rig up error in EPS also exists with electric fault simultaneously, even may burn out circuit, cause systemic breakdown.
Utility model content
In order to overcome the above problems, the utility model provides that a kind of structure is simple, simple installation, reduction electric fault, the easy Storage battery protecting device that improves Electrical Safety, improve system reliability.
The technical solution of the utility model is: described device comprises contactor one, contactor two, soft start resistance R3 and control board, described contactor one is arranged on battery positive voltage and plays disjunction effect, described contactor two is in parallel with soft start resistance R3, described control board is provided with rectifier bridge, described device also comprises resistance R1, R2, electric capacity C1, C2, C3, described rectifier bridge, resistance R1, R2 connects successively, resistance R2 is in parallel with electric capacity C1, storage battery by rectifier bridge at resistance R1, R2 place and contactor 1 trigger end form dividing potential drop, described electric capacity C2, C3 is connected in parallel on contactor two rear end.
The utility model structure is simple, simple installation, fail safe is high, the use electric fault because storage battery connection error and misoperation cause can be prevented, EPS reliability is improved greatly, the use electric fault because misoperation causes mainly is avoided in effect of the present utility model exactly when storage battery comes into operation, improve electrical safety.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
Embodiment
A kind of easy Storage battery protecting device, described device comprises contactor one, contactor two, soft start resistance R3 and control board, described contactor one is arranged on battery positive voltage and plays disjunction effect, described contactor two is in parallel with soft start resistance R3, described control board is provided with rectifier bridge, described device also comprises resistance R1, R2, electric capacity C1, C2, C3, described rectifier bridge, resistance R1, R2 connects successively, resistance R2 is in parallel with electric capacity C1, described electric capacity C2, C3 is connected in parallel on contactor two rear end, storage battery by rectifier bridge at resistance R1, R2 place and contactor 1 trigger end form dividing potential drop, make the pressure drop of contactor one trigger end just above enable voltage, simultaneously, realized the soft start of storage battery by R3 in rear end, by R3 to rear end electric capacity C2, after C3 charging, after capacitance voltage reaches certain amplitude, contactor two adhesive, realize storage battery power supply.
Contactor one conducting voltage is 100Vdc, suppose that rated direct voltage is 384Vdc, then R1 and R2 all value 3.4K, R1 connects front end a rectifier bridge KBU808, a R2 rear end filter capacitor C1 in parallel, storage battery forms dividing potential drop by rectifier bridge at R1, R2 and contactor one trigger end, and contactor one trigger end pressure reduction is about 160V, make contactor one adhesive, storage battery is powered to rear end.As storage battery because electric discharge for a long time causes electricity wretched insufficiency, then contactor one trigger end pressure reduction is less than 100Vdc, and contactor one not adhesive, storage battery and rear end disconnect, and prevent battery overdischarge.In like manner, as accumulator polarity connects instead, due to the single-phase on state characteristic of rectifier bridge, contactor one trigger end no-voltage, contactor one not adhesive, storage battery and rear end disconnect, and prevent from, because accumulator polarity connects instead, burning out rear end equipment.Contactor two conducting voltage is 300V, after contactor one adhesive, charged to rear end electric capacity C2, C3 by soft start resistance R3, R3 plays metering function at this place, prevents C2, C3 capacitance charging current too large, causes Head switches to trip, after the voltage of C2 electric capacity exceedes the conducting voltage of contactor two, contactor two adhesive, storage battery is connected with rear end equipment normally, can normal power supply.
