Embodiment
As shown in Figure 1; non-power consumption electronic starter of the present invention; comprise: circuits for triggering 22 and electronic switching circuit 23; the output of circuits for triggering 22 is that public connecting end and the control end of electronic switching circuit 23 of bidirectional triode thyristor among the optocoupler U1 and resistance R 4 is that the control end of bidirectional triode thyristor T1 links to each other; the control end of circuits for triggering 22 be among the optocoupler U1 light-emitting diode just; negative pole is serially connected between the resistance R 1 and capacitor C 3 in the delay control circuit 21; the two ends of the light-emitting diode among the optocoupler U1 are in parallel with capacitor C 2; also be serially connected with overheating protection circuit in the output loop of described electronic switching circuit 22; in the present embodiment, this overheating protection circuit is positive temperature thermistor RT1.During actual fabrication, this non-power consumption electronic starter is provided with three terminals J1, J2, J3, the resistance R 2 among wherein terminals J1 and the J2 and connect and link to each other with positive pole, a end of resistance R 3 in the circuits for triggering 22 and the contact J4 of the positive temperature thermistor RT1 in the electronic switching circuit 23 of diode D1 in the delay control circuit 21, terminals J3 and delay control circuit 21 and the public connecting end of capacitor C 3, an end of the resistance R 4 in the circuits for triggering 22 and the cathode terminal of the bidirectional triode thyristor T1 in the electronic switching circuit 23 link to each other.During practical application, terminals J1, J2 and connect the back link to each other with zero line with the phase line of AC220V alternating current respectively with terminals J3, also be serially connected with a startup capacitor C 1 that is used for phase shift between terminals J2 and the J3, two terminals J7 of the main winding M of compressor link to each other with zero line with the phase line of AC220V alternating current respectively with J9, the end of the auxiliary winding S of compressor and terminals J9 also connect, and the other end links to each other with the cathode terminal of bidirectional triode thyristor T1 by terminals J8.
Operation principle of the present invention is: compressor start moment, and need allow its main winding M and auxiliary winding S work simultaneously, provide bigger moment of torsion to compressor; During operate as normal, auxiliary winding S quits work behind the compressor start.The course of work of above-mentioned starter is exactly how to control the process of auxiliary winding S break-make: feelings say down that before powering on to starter, the electricity among capacitor C 2 and the C3 has all been put usually; Powered on moment, at the positive half cycle of alternating current, capacitor C 2 is charged by diode D1 and resistance R 1, R2, because the Capacity Ratio of capacitor C 2 is less, capacitor C 2 is filled very soon---more much smaller than the time that mains switch closes a floodgate; And for capacitor C 3, because the Capacity Ratio of capacitor C 3 is bigger, the charging interval of capacitor C 3 is long, positive half cycle at alternating current, by diode D1, light-emitting diode among resistance R 1 and the optocoupler U1 charges to it, negative half period at alternating current, it is charged by the light-emitting diode among the optocoupler U1 by capacitor C 2, the charging interval of capacitor C 3 is exactly the time of delay of this delay control circuit 22, usually be set between 0.2～1 second, the conduction period of the light-emitting diode in optocoupler U1, the bidirectional triode thyristor conducting among the optocoupler U1 is by resistance R 3 and R4 dividing potential drop, bidirectional triode thyristor T1 control end obtains voltage, when this voltage reaches triggering level, silicon symmetrical switch T1 conducting, auxiliary winding S powers on; Silicon symmetrical switch T1 automatically shut down at the zero point of alternating current, and after the zero crossing, circuit 22 triggering and conducting once more are triggered; Arrive when the time of delay of setting, promptly after the C2 abundance, the light-emitting diode among the optocoupler U1 is by (no longer including electric current flows through), and the bidirectional triode thyristor among the optocoupler U1 also ends thereupon, and bidirectional triode thyristor T1 is automatically shutting down behind zero crossing, and auxiliary winding S quits work.At this moment, compressor has started and has begun operate as normal.At auxiliary winding S duration of work, if current anomaly (as surpassing the limiting value of setting), thermistor RT1 disconnects because of heating makes its two contacts J4 and J5, makes auxiliary winding S quit work at once, avoids auxiliary winding S to be burnt out; When at once sending a telegram here this situation again after running into unexpected power failure, owing to deposit electricity in the capacitor C 2 in the starter, guaranteed that the light-emitting diode among the optocoupler U1 can conducting, the bidirectional triode thyristor among the optocoupler U1 can conducting yet, thereby auxiliary winding S can not work; Have only when have a power failure surpassing certain hour, etc. depositing after electricity put substantially of capacitor C 2, starter just can start auxiliary winding S and work when powering on greater than 45 seconds and when the temperature of resistance R T1 (common model is PTC) is lower than Curie-point temperature the general time of setting.
The present invention cooperatively interacts by delay control circuit 21 and circuits for triggering 22, realized the function of zero cross fired and time delayed turn-off well, and this starter itself is consumed power hardly, so just reduce the loss of electric energy, strengthened the energy-saving effect of refrigerator and air-conditioning.This starter is by the conducting of bidirectional triode thyristor and the break-make of ending to come control circuit, and is simple and reliable for structure, long service life.In addition, also be serially connected with overheating protection circuit in the electronic switching circuit 23, make auxiliary winding S obtain good protection.
