Abstract
The utility model relates to a PTC bidirectional silicon controllable starter for refrigeration compressor, comprising two PTC and a bidirectional thyristor. The two PTC are connected with each other in parellel and are connected with the bidirectional thyristor. One of the two PTC is connected with a triggering terminal of the bidirectional thyristor. The other PTC is connected with a lead-through terminal of the bidirectional thyristor. Compared with a general PTC starter, the utility model mainly solves the problem of a large loss of a PTC. Thus, the starter can enhance the power-efficiency ratio of the compressor.
Description
(1) technical field: the utility model relates to the refrigerant compression machine technology, is a kind of PTC bidirectional triode thyristor starter that is used for refrigeration compressor.
(2) background technique: at present, the small-power Piston Refrigerant Compreessor generally starts with heavy hammer started device and positive temperature coefficient thermistor PTC starter.But have electrical spark to produce during the work of the heavy hammer started device of Yin Putong, can not be used in the compressor of inflammable matter such as R600a, PTC starter contactless switch has overcome the above-mentioned shortcoming of heavy hammer type starter, so R600a working medium compressor generally starts with the PTC starter.But common PTC starter is to be made of single PTC, be installed in the operation that PTC in the circuit will participate in motor for a long time, himself generate heat and to consume certain power, this starter resistance when starting beginning (normal temperature) is 9-24 ohm, and the motor secondary winding is connected, and bigger inrush current generates heat PTC rapidly, so that reach curie temperature, the sudden change of PTC resistance can increase several magnitude, makes the motor secondary winding be similar to disconnection.But in motor operation course, still there is very little electric current to exist in PTC and the secondary winding, thereby consumes power of electric motor, generally can consume more than the 3W.Electric efficiency is descended to some extent, thereby influence the Energy Efficiency Ratio of compressor, this is a fatal defective to high-efficient compressor.
(3) summary of the invention: the purpose of this utility model is to solve the big problem of existing common PTC starter consume, and a kind of energy-saving PTC bidirectional triode thyristor starter that is used for refrigeration compressor is provided.
Concrete scheme of the present utility model is: connect to form with a bidirectional triode thyristor after adopting two PTC parallel connections, one of them PTC is connected with the The Trigger of Bidirectional Triode Thyristor terminal, and another PTC then is connected with a Lead-through terminal of bidirectional triode thyristor.
The utility model has reduced the working loss of starter self in explosion-proof, be used for the Energy Efficiency Ratio that compressor can improve compressor.
(4) description of drawings:
Accompanying drawing is structure of the present utility model, fundamental diagram.
Among the figure: 1-PTC, 2-PTC, 3-bidirectional triode thyristor.
(5) embodiment:
Referring to accompanying drawing, be circuit structure of the present utility model in the dashed rectangle among the figure.The utility model is to be connected to form by the PTC1 of two parallel connections and 2 and bidirectional triode thyristors, and wherein PTC1 is connected with a Lead-through terminal of bidirectional triode thyristor 3, and PTC2 is connected with the trigger terminal of bidirectional triode thyristor 3.
The electrical connection of this starter in compressor is referring to accompanying drawing, its working principle is summarized as follows: after the K switch closure (being that compressor is connected power supply), PTC2 conducting and trigger bidirectional triode thyristor 3 conductings, thereby make the PTC1 conducting, 0.4-1.5 after second, the PTC1 resistance rises sharply, and the trigger voltage of bidirectional triode thyristor 3 is reduced and ends, and finishes the startup of compressor thus.
Internal resistance is very big during not conducting of bidirectional triode thyristor, adds the internal resistance of PTC itself, makes that the electric current that flows through PTC is minimum, and general loss can be controlled in the 0.5W.On the other hand, bidirectional triode thyristor conducting and by contactless can not produce spark, can satisfy the startup requirement of R600a compressor.
