Description

The refrigerant compressor starter circuit now widely used are the following :( a) shown in FIG. 3 with the auxiliary winding to start functioning at compressor start circuit includes a compressor ordinary PTC starter 2, in the steady operation with the main winding. 1, PTC resistor (i.e., a positive temperature coefficient thermistor) connected in series with the auxiliary winding 3, the start of the compressor due to the low temperature resistance of the PTC resistor 3 small, then there is considerable the current flowing through the PTC resistor compressor 3 through the auxiliary winding 2, with time due to generation of heat resistance 3 PTC resistance increases with increasing temperature, so that the current flowing through the auxiliary winding is reduced, but the PTC the resistance of resistor 3 is not infinitely increased, the compressor in normal operation of the circuit of the auxiliary winding is still a certain current, so that a certain power, it is unnecessary wastage. (B) shown in Figure 4 with a start saving type compressor starter circuit when the compressor starts functioning auxiliary winding 2 of the main series PTC resistor 3, 4 triac, controllable bidirectional while the control electrode G 4 in silicon (i.e., control electrode) and an end of the main PTC resistor 3 connected in parallel to the sub-PTC resistor 5, the current in the starter to start the compressor flows through the PTC resistor 5 sub-trigger triac , so that the main part of the compressor start-up current flows through the auxiliary winding. 3 PTC shunt resistor, with the increase of the extension of time such that the temperature of the PTC resistor increases the resistance of the current through the auxiliary winding decreases, the same principle because the sub PTC resistor 5 such that the increased resistance to flow through electrode G of triac current decreases, when the current is insufficient to trigger the triac triac is turned off, so that the main power of the PTC resistor does not generate power 3 consumption, but in the PTC resistor 5 and the sub compressor the auxiliary winding is still a relatively small current, so there is still some waste of power consumption.

SUMMARY

The object of The Start Relay is to overcome the drawbacks present in the prior art, to provide the normal operation after the startup phase to a compressor with virtually no power consumption of the compressor without electronic starter.

Detailed ways

The following embodiments in conjunction with embodiments of The Start Relay will be further described, the following examples only aspect of The Start Relay, The Start Relay is not limited.

Example

Electronic shown in FIG 1 PTC starter no power, it is mainly used to start the refrigeration compressor, the compressor windings Y normal operation of the main winding 1 and auxiliary winding 2, heat generated by the starter positive temperature coefficient sensitive resistors 3, 4 triac trigger circuit board consisting of P, positive temperature coefficient thermistor is connected to the auxiliary winding 2 of the compressor 4 groups 3 and triac in series, the positive temperature coefficient thermistor 3 the auxiliary winding of the compressor and the G 2 terminal is connected between the poles of the triac 4 parallel trigger circuit board P, the flip-flop circuit board P by the bridge rectifier 6, capacitors 7, 8 composed of a resistor, a rectifier bridge 6 positive, negative terminal between parallel capacitor 7, resistance 8, the AC terminal of the rectifier bridge 6 are each connected triac G electrode and a positive temperature coefficient thermistor 4 of the compressor 3 and the auxiliary winding connection terminals 2, a trigger circuit board P direct control of the triac 4 is turned on and off, so as to achieve through the secondary current of the control winding.

When the compressor 2 is turned on the power switch 10 and the thermostat 9 is closed the current through the compressor started auxiliary winding 2, the rectifier bridge to 6, the capacitor 7 triac trigger 4 is turned on, so that can be thyristor 4 in an energized state, when the current through the start portion of the compressor 4 and the triac PTC resistor flows through the auxiliary winding 23, and also starts charging capacitor 7, with the time in the start time of the compressor 7 constantly charging capacitor, the capacitor voltage rising charge current gradually decreases, when the current is reduced to below the trigger current of the thyristor 4 or less than 4 so that the holding current of the thyristor is automatically turned off, the compressor startup end, this time in a stable operation of the compressor stages, compressor current all through the main winding 1. When the thermostat is disconnected the compressor is stopped, some of the resistor 8 starts when the capacitor 7 is discharged, so that the potential difference is generated across the capacitor to the starter to start again, when the capacitor discharge is completed, the starter has been restored, wait after the thermostat closes the compressor starts again.

Briefly: When the power supply 10 to load the compressor, temperature control switch is closed to start the compressor to complete the triggering of the triac is turned on, the compressor start-up procedure implemented by the charging of the capacitor 7; when the temperature-dependent switch 9 after disconnection recovery program implemented by the discharge process of the starter resistor 8 of the capacitor 7, ready for the next start a compressor. Capacitor charging time is the start time of the starter start of the compressor, and the time of capacitive discharge resistor is the recovery time of the starter.

The capacitor charging is completed, the triac is turned off automatically after the compressor is started into the normal operation phase of the program ends, there is no way back to the auxiliary winding current flows in normal operation of the compressor stage, the starter and the compressor so that the auxiliary winding is not generating power. [0016] compared to that shown in the application of more current now, less energy-saving power starter i.e. FIG. 4, the present embodiment to a trigger circuit board 4 instead of the sub-PTC resistor 5, and a compressor startup program end into the normal operation phase, the auxiliary winding back road no current flows in the normal operation of the compressor stage, eliminating the power generated by the deputy PTC resistor 5, achieved without power in the true sense.
