Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, describe the utility model in detail;

Fig. 1 is circuit diagram of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.

With reference to Fig. 1, this embodiment is by the following technical solutions: UPS automatic switching, divide three parts, first is that start operating part is comprised of transformer T, electric bridge DQ, the first capacitor C 1, relay K, the first diode D1, the second resistance R 2, the second diode D2, the first triode Q1, the 3rd resistance R 3, the second capacitor C 2 etc.; After restoring electricity, by transformer T step-down, electric bridge DQ rectification is powered to relay K through the first capacitor C 1 filtering; At this time the base stage of the first triode Q1 is in high potential; the first triode Q1 conducting; because the normally opened contact of the turn-on relay work of the first triode Q1 is closed; UPS start; its current circuit is that the 12V direct current through electric bridge DQ rectification, the first capacitor C 1 filtering passes through relay K; the collector electrode one of the first triode Q1 is transmitted into ground; the first diode D1, the second diode D2 are for when the relay power-off; the inverse peak voltage that can produce provides discharge path, effectively protects the not breakdown damage of the first triode Q1.

Second portion is that open and close machine signal produces, and the 4th resistance R 4, the 3rd capacitor C 3, the 4th capacitor C 4, the 3rd diode D3, consists of, and 5V stabilized voltage power supply is given the first triode Q3, electronic controller IC1 power supply, the 8th resistance R 8 again, the 9th resistance R 9, the 3rd triode Q3, the 6th resistance R 6, the 6th capacitor C 6, electronic controller IC1 forms time delay reverse circuit when civil power is normal, A point has 12V direct voltage, give the 8th resistance R 8, the 9th resistance R 9 step-downs are added to the 3rd triode Q3 base stage, the 3rd triode Q3 is therefore with regard to saturation conduction, electric charge in the 6th capacitor C 6 is bled off rapidly, like this 2 of electronic controller IC1, 6 pin are drawn as electronegative potential, the electronic controller IC1 3 pin high potentials that overturn, this high potential signal walks to the second capacitor C 2, the 3rd capacitor C 3 is given the first triode Q1 starting-up signal, time is 3 seconds, after 3 seconds, because being full of, the second capacitor C 2 electric charges no longer include electric current by the b of the first triode Q1, the e utmost point and make the first triode Q1 cut-off, combination that Here it is above described start control section has completed boot action.

Normal power supply point transfers to while having a power failure again, A point has just lost 12V voltage, the 3rd triode Q3 has lost basic current and has ended, this just makes 2 of electronic controller IC1, 6 pin are because 5V electric current of voltage regulation is given the 6th capacitor C6 charging and slowly raise by the 6th resistance R 6, when be raised to electronic controller IC1 power supply 2/3 time, electronic controller IC1 is upset just, 3 pin transfer low-voltage (0V) to by high voltage (5V), the lower jumping signal of this sudden change is exactly the b that logical the tenth resistance R 10 is added to the second triode Q2, the off signal of the e utmost point, the delay time that this device arranges is 8 minutes, delay time length depends primarily on the 6th resistance R 6, the time constant of the 6th capacitor C 6.

Third part is shutdown operating part, there is the tenth resistance R 10, the second triode Q2, the 7th resistance R 7, the 5th capacitor C 5, photoelectrical coupler IC2 forms, off signal from second portion adds to the base stage of the second triode Q2 by the tenth resistance R 10, make the second triode Q2Q2 immediately just exit saturation conduction, make C dot circuit immediately rise to the high voltage (12V) the same with B point, this voltage is given the 5th capacitor C 5 chargings, charging current forms loop through the Light-Emitting Diode of photoelectrical coupler IC2 inside, light-emitting diode makes high illuminated triode conducting and produces off signal with regard to luminous, the duration of this signal is 3 seconds, this time can make UPS shutdown, and the 5th capacitor C 5 is exactly the main element that determines time length.

This embodiment has a power failure in burst, and UPS power supply can be closed ups power after 8 minutes automatically, after electrical network incoming call, can automatically open ups power.

More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
