Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of control device of the refrigeratory for transformer, is therefore beneficial to the improvement of soil and the growth of plant.
For achieving the above object, the technical scheme that the utility model is taked is: include the temperature sensor I of the Import & Export Department being arranged on refrigeratory and temperature sensor II, with the pickoff signals of temperature sensor I and temperature sensor II for according to and be the processor of output signal, the refrigeratory start-up connector that is control signal with the output signal of processor with the cooling effectiveness of this refrigeratory.
Owing to devising temperature sensor I and temperature sensor II, processor and refrigeratory start-up connector, the pickup of the temperature signal of the liquid coolant of input is exported by temperature sensor I and temperature sensor II pair of refrigeratory, based on signal, the cooling effectiveness high-low signal being exported refrigeratory by processor is control signal, carry out priority to refrigeratory according to cooling effectiveness height to open, no longer signal based on transformer oil surface temperature and winding temperature signal, therefore improves the utilization ratio of refrigeratory.
The utility model devises, processor is set to include demodulator of PM signal PM and signal processing controller, refrigeratory start-up connector is set to auxiliary reclay, the controller of A.C. contactor and refrigeratory, also include alarm, temperature sensor I and temperature sensor II are separately positioned on the Import & Export Department of refrigeratory and are set to respectively be connected with the input port of demodulator of PM signal PM, the output port of demodulator of PM signal PM is set to be connected with the input port of signal processing controller, the output port of signal processing controller is set to be connected with A.C. contactor and alarm with by auxiliary reclay respectively, A.C. contactor is set to be connected with the controller of refrigeratory.
The utility model devises, and temperature sensor I, temperature sensor II, auxiliary reclay, A.C. contactor and alarm are set to corresponding with one group of port of demodulator of PM signal PM and signal processing controller.
Technique effect of the present utility model is: temperature sensing sensor is arranged on the import and export of transformer cooler, in real time induction import and export oil temperature.The output of temperature sensing sensor links demodulator of PM signal PM by line, demodulator of PM signal PM analyzes temperature value, digital quantity signal is linked the signal receiving end of programming controller by connection, signal processor calculates the cooling effectiveness of corresponding refrigeratory, the duty of corresponding refrigeratory is judged according to cooling effectiveness, when cooling effectiveness height, preferential this refrigeratory of startup.When cooling effectiveness is low, the refrigeratory that preferential other cooling effectiveness of startup is relatively high.When cooling effectiveness is very low, controls warning auxiliary reclay and send alerting signal.The lead-out terminal of programming controller connects auxiliary reclay, and difference in functionality undertaken by different auxiliary reclay, and part auxiliary reclay controls A.C. contactor, thus passes through the start and stop of A.C. contactor controlled cooling model device; Part auxiliary reclay connects alarm, provides alerting signal.The utility model has the sensitive feature of response, the utility model is on the basis of conventional cooler switch board, add refrigeratory cooling effectiveness monitoring part, measure refrigeratory by temperature sensing sensor and import and export oil temperature calculating cooling effectiveness, according to the start and stop priority of the height setting refrigeratory of cooling effectiveness.Make refrigeratory switch board more intelligent, more efficiently.
In the technical program, the cooling effectiveness high-low signal of refrigeratory is the temperature sensor I of control signal and temperature sensor II, processor and refrigeratory start-up connector is important technical characteristic, in the technical field of the control device of the refrigeratory for transformer, there is novelty, creativeness and practicality.
Four, accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Five, embodiment
Fig. 1 is an embodiment of the present utility model, illustrates the present embodiment by reference to the accompanying drawings, includes temperature sensor I 1, temperature sensor II 2, demodulator of PM signal PM 3, signal processing controller 4, auxiliary reclay 5, A.C. contactor 6 and alarm 7,
Temperature sensor I 1 and temperature sensor II 2 are separately positioned on the Import & Export Department of refrigeratory and are set to respectively be connected with the input port of demodulator of PM signal PM 3, the output port of demodulator of PM signal PM 3 is set to be connected with the input port of signal processing controller 4, the output port of signal processing controller 4 is set to be connected with A.C. contactor 6 and alarm 7 with by auxiliary reclay 5 respectively, and A.C. contactor 6 is set to be connected with the controller of refrigeratory.
In the present embodiment, temperature sensor I 1, temperature sensor II 2, auxiliary reclay 5, A.C. contactor 6 and alarm 7 are set to corresponding with one group of port of demodulator of PM signal PM 3 and signal processing controller 4.
