Make and further specifying below in conjunction with Fig. 1,2 pairs of the utility model:
This energy-saving telesecurity electric discharge device comprises charger 10, battery module 20, intelligent inversion module 30, user load 40, local runtime monitoring module 50, long-range host computer 60, harmonic wave control module 70, the first diode D1, the second diode D2, the 3rd diode D3, charging electric switches set QF1, discharge motor switch group QF2.
Under the charging operating state, charging electric switches set QF1 is closed, and discharge motor switch group QF2 breaks off, and charger 10 is on the one hand to battery module 20 chargings, on the other hand to user load 40 power supplies.
Under the discharge operating state, battery module 20 also is that batteries has following two kinds of discharge modes to select:
First kind of discharge mode is to limit the certain value that charger 10 voltages are lower than battery module 20 ceiling voltages; And make charging electric switches set QF1 break off; Make that simultaneously discharge motor switch group QF2 is closed, then one side battery module 20 is through the electric energy feedback grid of intelligent inversion module 30 harmonic abatement modules 70 with battery module 20; The negative pole of the negative pole of the positive pole of the positive pole of battery module 20, the first diode D1, user load 40, user load 40, the second diode D2 and battery module 20 constitutes current supply circuit on the other hand, and battery module 20 is to user load 40 power supplies.This moment, though the output voltage of battery module 20 is higher than charger 10 voltages, battery module 20 was to charger 10 power supplies because anti-adverse current module is the effect of the 3rd diode D3 also; And when the output voltage of battery module 20 was lower than the voltage of charger 10, charger 10 was resumed work and is supplied power to user load 40.
Second kind of discharge mode is under the situation of the output voltage that is higher than battery module 20 of the output voltage at charger 10; Charging electric switches set QF1 is broken off; QF2 is closed for discharge motor switch group; Then battery module 20 is connected with intelligent inversion module 30 and constitutes discharge loop on the one hand, and intelligent inversion module 30 is through the electric energy feedback grid of harmonic wave control module 70 with battery module 20; Charger 10 is to user load 40 power supplies on the other hand.Because the output voltage of charger 10 is higher than the output voltage of battery module 20 at this moment; The first diode D1 and the second diode D2 can not conductings; Therefore charger 10 can not charge to battery module 20 in second kind of discharge mode, thereby has guaranteed that battery module 20 is through 70 discharges of intelligent inversion module 30 harmonic abatement modules.
