Abstract
The utility model provides a zero-power-consumption starter for a small-size hermetically-sealed refrigeration compressor, which comprises a PTC (positive temperature coefficient) thermistor connected in series to a secondary winding loop of the refrigeration compressor and a PTC thermistor Rt, wherein one terminal of the PTC thermistor Rt is connected to the control electrode of a bi-directional silicon controlled rectifier, and the other terminal thereof is connected between the zero-line terminal of the power input and the M terminal of the primary winding. According to the technical scheme of the utility model, the thermistor Rt is used for controlling the bi-directional silicon controlled rectifier, wherein when the refrigeration compressor is started, the bi-directional silicon controlled rectifier is in a conducting state because the resistance of Rt is lower, and after the refrigeration compressor is started, the control electrode of the bi-directional silicon controlled rectifier is disconnected because the resistance of Rt becomes higher, the electric energy is hardly consumed by the PTC thermistor during the normal operation of the refrigeration compressor, thus achieving the significant effects of energy conservation and environmental protection.
Description
Technical field
The utility model relates to the small-sized totally-enclosed refrigerating compressor power consumption starter.
Background technology
Small-sized totally-enclosed refrigerating compressor does not need auxiliary winding to participate in work again after starting, and desirable state is that the auxiliary winding loop disconnects after compressor start, makes no longer consumed power of auxiliary winding.To this, solution commonly used at present is a serial connection PTC positive temperature coefficient thermistor in the auxiliary winding loop, it is minimum at the resistance in a flash of compressor start, and generate heat rapidly and make its resistance sharply increase, minimum by electric current, thereby after compressor start, the approximate auxiliary winding loop that disconnects.However, when compressor operating, in order to keep its temperature, the PTC positive temperature coefficient thermistor still needs to consume certain electric energy, about the about 3W of its numerical value, and long this accumulative total, waste of electric energy is also very considerable.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of small-sized totally-enclosed refrigerating compressor power consumption starter, and starter that can be more in the past is more energy-conservation.For this reason, the utility model is by the following technical solutions: it comprises the PTC positive temperature coefficient thermistor that is connected on the described compressor auxiliary winding loop, between the S of first end of described PTC positive temperature coefficient thermistor and auxiliary winding end, also be serially connected with bidirectional triode thyristor, second end of described PTC positive temperature coefficient thermistor is connected with power supply input zero line side, and described starter also is provided with positive temperature coefficient thermistor R
t, described positive temperature coefficient thermistor R
tAn end be added in the control utmost point of bidirectional triode thyristor, the other end is added between the M end of power supply input zero line side and main winding.Owing to adopt the technical solution of the utility model, can utilize thermistor R
tControl to bidirectional triode thyristor, when compressor start, because the less bidirectional triode thyristor triggering and conducting that makes of Rt resistance value, after compressor start, the Rt resistance value of being heated becomes very big, the bidirectional triode thyristor control utmost point is turn-offed, thereby make when the compressor operate as normal, the PTC positive temperature coefficient thermistor is consumed power no longer almost, has played the effect of great energy-conservation and environmental protection.
Description of drawings
Fig. 1 is the circuit diagram of embodiment that the utility model provides.
Embodiment
With reference to accompanying drawing.The utility model comprises the PTC positive temperature coefficient thermistor 11 that is connected on the described compressor start device auxiliary winding loop; the second end 11-2 of PTC positive temperature coefficient thermistor 11 connects power supply input zero line side N; between the S of the first end 11-1 of described PTC positive temperature coefficient thermistor and auxiliary winding 10 end, be serially connected with bidirectional triode thyristor 12; the C end of compressor 100 links to each other with power input L through overheat protector 14 again, and described starter also is provided with positive temperature coefficient thermistor R
t, described positive temperature coefficient thermistor R
tAn end be added in the control utmost point 3 of bidirectional triode thyristor, the other end is added between the M end of power supply input zero line N end and main winding, the first end 11-1 of described PTC positive temperature coefficient thermistor 11 links to each other with bidirectional triode thyristor 12 anodes 2, and the negative electrode 1 of bidirectional triode thyristor is connected with the S of auxiliary winding 10 end.
PTC positive temperature coefficient thermistor 11 is the thermistor of ampere level, and described ampere level can be 1～12 ampere.Positive temperature coefficient thermistor R
tBe the thermistor of milliampere level, described milliampere of level can be 1 milliampere-100 milliamperes.
After utilizing the utility model, in the moment of compressor energising starting, because R
tResistance value under the normal temperature is very little, making bidirectional triode thyristor 12 conductings, compressor auxiliary winding finish starting sequence by trigger current when by starting current, and R
tTemperature rise surpasses switch temperature (Curie temperature) point, its resistance value sharply rises, and the SCR control utmost point and power supply N (M) end be open circuit almost, thereby closes bidirectional triode thyristor, make the electric current in auxiliary winding loop almost nil, thereby be implemented in the no power consumption on the PTC positive temperature coefficient thermistor 11.
Further, between the control utmost point 3 of the S of auxiliary winding end and bidirectional triode thyristor, also be added with inductance L in parallel and resistance R.Purpose is to utilize the back-emf of inductance to close bidirectional triode thyristor 12 more reliably, makes starting winding loop electric current almost nil.In the enforcement also available line replace around equivalent resistance.
