Abstract

The utility model discloses a control circuit of a vaccine cold storage refrigeration compressor. The control circuit comprises a compressor motor M which is communicated with a three-phase supply through a circuit breaker QS, an AC contactor KM1 and a thermal relay FR; the circuit is further connected with a fuse FU and an AC contactor KM2 and is characterized by being further provided with an intelligent controller ICR; the compressor motor M is provided with a pressure sensor P and a temperature sensor C; the circuit between the circuit breaker QS and the AC contactor KM1 is further provided with a current sensor W; and the pressure sensor P, the temperature sensor C and the current sensor W are controlled by the intelligent controller ICR. The control circuit of the vaccine cold storage refrigeration compressor is smart in design and rational in layout and is capable of realizing a plurality of protections such as overload, over-temperature, over-voltage, over-current, phase failure and open circuits for the compressor.

Description

Vaccine freezer refrigerating compressor Control Cprant
Technical field
The utility model relates to a kind of control circuit, particularly a kind of vaccine freezer refrigerating compressor Control Cprant.
Background technique
After the production of vaccine of medicine is come out, need be placed in the freezer, under low temperature environment, preserve; And very strict and harsh to the requirement of storage temperature, so the reliability of freezer refrigerating system is just very important, traditional freezer refrigerating compressor adopts mechanical overload protection arrangement; Work as components and parts like this and mechanical fatigue occurs; Or after the phenomenon such as related elements is aging, can lose protective action to compressor, the situation that refrigeration compressor burns might appear; Therefore reduce the reliability of compressor, might influence the refrigeration of freezer.Therefore needs are a kind of now can result of the above problems.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology; It is ingenious to propose a kind of design; Rationally distributed, can realize overload, overtemperature, superpressure, overcurrent, the phase shortage of compressor, the vaccine freezer refrigerating compressor Control Cprant of kinds of protect such as open circuit.
The technical solution of the utility model is: a kind of vaccine freezer refrigerating compressor Control Cprant; Comprise the compressor electric motor M that is connected with three phase mains through circuit breaker Q S, A.C. contactor KM1 and thermorelay FR; In circuit, also be connected with fuse F U and A.C. contactor KM2; It is characterized in that: also be provided with intelligent controller ICR on the described circuit; Compressor electric motor M is provided with pressure transducer P and temperature transducer C, on the circuit between circuit breaker Q S and the A.C. contactor KM1, also is provided with current sensor W, and the signal that pressure transducer P, temperature transducer C and current sensor W gather is all sent into intelligent controller ICR.
The utility model is compared with existing technology, has following advantage:
The vaccine freezer refrigerating compressor Control Cprant of this kind of structural type; It is simple in structure, designs ingeniously, and currently available vaccines, existing vaccines freezer refrigerating compressor only adopts mechanical overload protection arrangement that it is protected; After this overload protection arrangement uses the long time; Wear out during can or being correlated with owing to mechanical fatigue and lose protective function, can't protect refrigeration compressor again, and traditional refrigeration compressor only has overload protection function; And can't monitor and protect other parameters of compressor, function is comparatively single.Control circuit as herein described has increased intelligent controller ICR in compressor circuit; Thereby possessed the protection of multiple functions such as overload protection, overtemperature prote, overpressure protection, overcurrent protection, open-phase protection, open circuit protection; Improved the reliability of compressor operating; Guaranteed the standard environment in vaccine workshop effectively, for the preservation of vaccine provides reliable hardware foundation.Therefore we can say that it has possessed multiple advantage, be particularly suitable for applying in the art that its market prospects are very wide.
Description of drawings
Fig. 1 is the utility model embodiment's a circuit block diagram.
Embodiment
Below with the embodiment of accompanying drawings the utility model.As shown in Figure 1: a kind of vaccine freezer refrigerating compressor Control Cprant; Comprise the compressor electric motor M that is connected with three phase mains through circuit breaker Q S, A.C. contactor KM1 and thermorelay FR; In circuit, also be connected with fuse F U and A.C. contactor KM2; On circuit, also be provided with intelligent controller ICR; On compression motor M, be connected with pressure transducer P and temperature transducer C, be used to detect the force value and the temperature value of compression motor, on the circuit between circuit breaker Q S and the A.C. contactor KM1, also be provided with current sensor W; Be used for the current value on the testing circuit, the signal that above-mentioned pressure transducer P, temperature transducer C and current sensor W gather is all sent into intelligent controller ICR.
The working procedure of the utility model embodiment's vaccine freezer refrigerating compressor Control Cprant is following: compressor electric motor M is in the process of work; The force value and the temperature value of pressure transducer P and temperature transducer C detection at any time motor; Current value in the current sensor W detection at any time circuit, and these numerical value are converted into signal feed back give intelligent controller ICR, whether the parameters in the intelligent controller ICR detection at any time circuit meets the requirements; If problem is then made corresponding adjustment.
Therefore this control circuit has possessed the protection of multiple functions such as overload protection, overtemperature prote, overpressure protection, overcurrent protection, open-phase protection, open circuit protection, has improved the reliability of compressor operating.
