Brief description
Fig. 1 is the circuit diagram of accumulator automatic charge control unit.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of accumulator automatic charge control unit, including rectifier bridge t, electric capacity c1, audion v1 and unidirectional
The port 1 of IGCT q1, described rectifier bridge t connects resistance r1 and electric capacity c1, and the other end of electric capacity c1 connects 220v alternating current, whole
Flow the port 2 connection electric capacity c3 of bridge t, the dynamic of the contact k-1 of the colelctor electrode of audion v1, the negative electrode of diode d2 and relay k
End, the base stage of audion v1 connects potentiometer rp1, and the other end of potentiometer rp1 connects the anode of diode d2, audion v1's
Emitter stage connects resistance r2, the negative electrode of diode d1 and relay k, and the other end of resistance r2 connects resistance r3 and unidirectional thyristor
The control pole of q1, the other end of resistance r3 connects the negative pole of accumulator e, the other end of electric capacity c3, the negative electrode of unidirectional thyristor q1
With the port 4 of rectifier bridge t, not moved end 1 of the contact k-1 of anode connection relay k of diode d1, the other end of relay k
Connect loudspeaker b, the other end of loudspeaker b connects the anode of unidirectional thyristor q1, the not moved end 2 of the contact k-1 of relay k connects storage
The other end of battery e.
Diode d1 is light emitting diode, and diode d2 is Zener diode.
Operation principle of the present utility model is: under original state, the contact k-1 of relay k connects not moved end 2,220v city
Piezoelectric voltage, after the capacitance-resistance voltage reduction circuit blood pressure lowering of resistance r1 and electric capacity c1 composition, is carrying out rectification, electric capacity c3 through rectifier bridge t
For filter capacitor, it is added in accumulator e from the voltage of the port 2 of the rectifier bridge t output contact k-1 through maximum current relay k and carries out
Charge, now, because the voltage of e is relatively low, therefore its undertension is not led with puncturing Zener diode d2, audion v1 cut-off
Logical, do not have electric current to flow through relay, with the carrying out charged, the voltage of e constantly raises, after e is fully charged, its voltage be enough to hit
So that the base stage of audion v1 obtains trigger voltage after wearing diode d2, therefore audion v1 turns on, and now voltage is through resistance
After r2, r3 partial pressure, IGCT q1 is made to turn on, electric current flows through relay k so as to contact k-1 connects not moved end 1, now voltage warp
Equally it is able to maintain that the conducting of unidirectional thyristor q1 and relay k, light emitting diode d1 lights, and loudspeaker b sends out after crossing diode d1
Go out chimes of doom, remind user battery to fill with electricity.
