Description
Technical field
The utility model relates to a kind of coupler circuit, especially a kind of based on silicon controlled thermistor temp auto-controlled temp. controllable circuit.
Background technology
In the electrical equipment of other use controllable silicon heated for controlling temperatures such as electric chafing dish, electric oven, all adopt silicon-controlled voltage regulation module circuitry, this module need with temperature controller with the use of or external potentiometer from Row sum-equal matrix output power, when using temperature controller, cost higher volumes is comparatively large, and common external potentiometer has and cannot reach temperature automatically controlled.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of temperature automatically controlled thyristor regulating die block of low cost, and it by carrying out transforming on original thyristor regulating die block.
The technical solution of the utility model is:
A kind of based on silicon controlled thermistor temp auto-controlled temp. controllable circuit, comprise thyristor regulating die block, temperature control module, it is characterized in that: described silicon-controlled voltage regulation model calling has temperature control module, described temperature control module comprises resistance, potentiometer and thermistor, described resistance input end connects thyristor regulating die block output terminal, described resistance output terminal connects potentiometer first pin and crus secunda respectively, described potentiometer tripod connects thermistor input end, and described thermistor output terminal connects silicon-controlled voltage regulation module input.
The resistance of described resistance is 1000 ohm.
The resistance of described potentiometer is 500000 ohm.
Described thermistor is negative tempperature coefficient thermistor.
As improvement of the present utility model: described thermistor adopts posistor, thermistor and resistance transposition.
Principle of work of the present utility model:
Thyristor regulating die block, for the industry very proven technique and there is various deformation, therefore the utility model repeats no more, but it should be noted that, the thyristor regulating die block that the utility model is mentioned comprises any one disclosed thyristor regulating die block before the utility model applying date;
Temperature control module is incorporated to voltage regulating module afterpotential device when being adjusted to minimum, negative tempperature coefficient thermistor two ends intrinsic standoff ratio is larger, now controllable silicon full power exports, when raising along with load temperature, negative tempperature coefficient thermistor resistance reduces, drops is divided at thermistor two ends, controllable silicon exports and diminishes, when silicon controlled heating and the heat radiation of load reach balance, load temperature is not in rising, the resistance of adjusting resistance can set maximum temperature, and output power can be adjusted between 0-is maximum by potentiometer and adjust, thus make the temperature variation of load to process different objects, especially the load of electric chafing dish class is applicable to.
The beneficial effects of the utility model are: the utility model structure is simple, achieve temp. controllable and temperature automatically controlled by being incorporated to potentiometer and thermistor on the basis of grand master pattern block, have the advantage of low cost, small size and robotization.
