Abstract
The utility model is a zero-power-consumption starter for fully enclosed refrigerating compressor. The starter comprises bi-directional silicon controlled rectifier (SCR), and a thermistor connected with turn-on end of the SCR. The utility model is characterized by connecting trigger end of the SCR with a trigger branch circuit formed by connecting a thermistor or ordinary resistance with a capacitor in series. The utility model has simple structure and low cost, realizes zero power consumption of starter, and improves performance-energy ratio of compressor.
Description
(1) technical field: the utility model relates to the refrigerant compression machine technology, is a kind of Totally Closed Refrigerating Compressor Non Power Consumption Actuator.
(2) background technology: at present, the small-power Piston Refrigerant Compreessor generally uses weight starter and semistor (PTC) starter to start.But there is electric spark to produce during the work of Yin Putong weight starter, can not be used in the compressor of explosive working medium such as R600a, PTC starter noncontacting switch has overcome the above-mentioned shortcoming of Weight type starter, so R600a working medium compressor generally starts with the PTC starter.But PTC can participate in the operation of motor for a long time, himself generating heat to consume certain power, electric efficiency is descended to some extent, thereby influence the Energy Efficiency Ratio of compressor, because of existing high-efficient compressor is more and more higher to the COP requirement, so the power consumption of PTC is a fatal defective to high-efficient compressor.200420076707.2 number patent disclosure a kind of PTC bidirectional triode thyristor starter that is used for refrigerant compressor, make the power consumption of starter obtain bigger reduction, but still have the above power consumption of 0.5W.
(3) summary of the invention: the purpose of this utility model is to solve the problem that PTC bidirectional triode thyristor starter still has power consumption, and a kind of Totally Closed Refrigerating Compressor Non Power Consumption Actuator is provided.
Concrete scheme of the present utility model is the improvement to PTC bidirectional triode thyristor starter, it includes bidirectional triode thyristor, conduction terminal at bidirectional triode thyristor is connected with a thermistor, and its improvement is: the The Trigger of Bidirectional Triode Thyristor end is connected with a triggering branch road by thermistor or a conventional, electric-resistance and a capacitances in series.
Be the charging rate of speed-up capacitor, fast break, connecting in described triggering branch road in the utility model has added a diode.
In order suitably to discharge the electric weight of electric capacity, start once more helping, the utility model is in parallel with electric capacity in described triggering branch road to have inserted a resistance.
Operation principle of the present utility model is: when compressor start, the resistance and the electric capacity conducting that trigger in the branch road trigger bidirectional triode thyristor, the thermistor conducting that the bidirectional triode thyristor conduction terminal is connected, this thermistor is by bigger motor auxiliary winding starting current, and very fast heating, make the very fast rising of its resistance value, when its resistance value rises to a maximum, motor starting circuit is disconnected substantially, finish the starting of compressor.When motor moves, according to the characteristic of electric capacity, when electric capacity after being full of electricity, the triggering branch road that electric capacity and resistance constitute is equivalent to open circuit, thereby has realized no power consumption.
The utility model is simple in structure, and cost is low, has mainly solved the problem that existing compressor start device has power consumption, has realized that starter does not have power consumption work, can improve the Energy Efficiency Ratio of compressor.

Fig. 1 is the structure principle chart of one of structure of the present utility model;
Fig. 2 is two a structure principle chart of structure of the present utility model;
Fig. 3 is three a structure principle chart of structure of the present utility model.
Among the figure: 1-bidirectional triode thyristor, 2, the 3-thermistor, 4-electric capacity, 5-diode, 6-resistance, 7-resistance.
(5) embodiment:
Example 1:, be the circuit structure of one of the utility model structure in the dashed rectangle among the figure referring to Fig. 1.The utility model includes a bidirectional triode thyristor 1, be connected with a thermistor 2 with the conduction terminal of bidirectional triode thyristor 1, the trigger end of bidirectional triode thyristor 1 is connected with the quick resistance 3 of electric heating (or conventional, electric-resistance), and the triggering branch road of electric capacity 4 series connection promptly constitutes basic structure of the present utility model.
Example 2:, be two circuit structure of the utility model structure in the dashed rectangle among the figure referring to Fig. 2.It is more optimizing structure of example 1, and its basic structure is with example 1, and difference is that its triggering branch road is to be in series by a conventional, electric-resistance 6 and electric capacity 4, and series connection has inserted a diode 5 in triggering branch road, to be full of electric capacity 4 fast, quicks break.
Example 3: referring to Fig. 3, it among the figure three circuit structure of the utility model structure, it is more optimizing structure of example 1, its basic structure is with example 1, difference is in parallelly with electric capacity 4 in triggering branch road to have inserted a discharge resistance 7, with suitable release electric capacity electric weight, help starting once more.
