Abstract

The utility model relates to an intelligent monitoring controller for motor operation, belonging to a protector or a controller of three-phase asynchronous motor, an electrical parameters sensor 2, a computer 6 and an optoelectronic isolation 7 are fixed in the case 1, a display 3, a manual operation button 4 and three pairs of output terminal 5 are arranged on the the case 1, a computer 6 is connected with a sensor 2, a display 3, a manual operation button 4 and an optoelectronic isolation 7 respectively, the computer 6 is connected with three pairs of output terminal 5 through optoelectronic isolation 7. The utility model sufficiently utilizes operation and control function of single chip computer, especially digital display function for preset current and existing current on site, therefore, the operator can learn whether the controlled motor overloads very intuitively, program prepated by single chip microcomputer can be used to generate an adjustable delay time easily for delayed start of the motor. The distribution box assembled by the the utility model can be very simple.

Description

Motor operation intellectual monitoring controller
One, technical field:
The utility model belongs to a kind of protector or controller of threephase asynchronous, especially a kind of motor operation intellectual monitoring controller.
Two, background technology:
Three-phase asynchronous motor protector only has one road output control terminal in the known technology; it can only be cut off the electricity supply when motor work is undesired; function singleness; the distribution box that is used to start, control threephase asynchronous that is assembled into; also needing to assemble all multicomponents such as current transformer, ammeter, the time relay, push-button switch, A.C. contactor and decompressing unit assembles by lead; structure and complex circuit, easy break-down and inconvenience are safeguarded.
Three, summary of the invention:
Technical problem to be solved in the utility model is to propose a kind ofly have two-way or three road output control terminals to realize startup to motor with direct driving A.C. contactor, operation, stop, fault is met an urgent need and is stopped to wait operation, and with electric current, the collection of voltage and demonstration, phase shortage, the judgement of overload fault, start the generation of delay time, manually " startup " " stop " acceptance of operational order, multinomial functions such as the generation of output signal are in one, and use monolithic computer to carry out co-ordination by execution of program instructions, promptly a kind of motor operation intellectual monitoring controller.
The measure that overcomes the above problems is that the housing internal fixation has electrical quantity transducer, computer and photoelectricity to isolate, display is installed on the housing, manual operation button and three pairs of outputs, computer is isolated with transducer, display, manual operation button and photoelectricity respectively and is connected, and computer and isolate by photoelectricity is connected with three pairs of outputs.
Advantage of the present utility model is, the computing and the controlled function of monolithic computer have fully been used, particularly to the digital display function of preset current and on-the-spot current electric current, whether the operator is got information about by controlled motor transships very much, the program of utilizing single-chip microcomputer to compile, can produce an adjustable delay time very easily, for the delayed firing of motor.Because 2 road or 3 road outputs are arranged, so the distribution box with its assembling is comparatively easy, use the distribution box that is used to start, control threephase asynchronous of the utility model assembling, only need increase exchanges contactor and decompressing unit get final product with a spot of lead connection again.
Four, description of drawings:
Fig. 1 is the utility model structural principle schematic block diagram
Fig. 2 is the circuit theory diagrams that embodiment 2 is used for the auto coupling decompression start threephase asynchronous
Fig. 3 is the circuit theory diagrams that embodiment 3 is used for reactor decompression starting threephase asynchronous
Five, body execution mode:
Embodiment 1: the utility model housing 1 internal fixation has electrical quantity transducer 2, computer 6 and photoelectricity to isolate 7, display 3 is installed on the housing 1, manual operation button 4 and output 5, computer 6 is isolated 7 with transducer 2, display 3, manual operation button 4 and photoelectricity respectively and is connected, and computer 6 is also isolated 7 by photoelectricity and is connected with output 5.Three-phase alternating current voltage is through the transducer input amplifier carries out the rectification amplification to signal after, become the corresponding digital amount through electrical quantity transducer 2 analog-to-digital conversion, computer 6 with its digital data acquisition after, send display 3 on the one hand, show parameters such as current electric current, voltage, the current parameters that presets of on the other hand 4 manual operations of manual operation button being imported and deposited in computer 6 compares, judge whether motor work is normal, and isolate 7 signals that send work or stop to output stage output 5 by photoelectricity.Output stage output 5 is provided with the logical interlock control circuit, prevent because of the front-end computer 6 accidental also mistakes of unstart Third Road of the first via or the second tunnel that cause with regard to starting, manual operation knob 4 can order computer 6 preferentially to start the output that stops, also can starting delay time preset and the motor rated current presets.Computer 6 is the monolithic computer control unit.
Embodiment 2: when the utility model was used for auto coupling decompression start threephase asynchronous 8, three pairs of outputs directly drove KM1.KM2.KM3 for 5 mouthfuls and finish starting, the operation of motor 8 and the overall process that stops.K1, K2 output 5 have voltage signal output simultaneously, KM1, KM2 adhesive, power supply passes through single-circuit transformer ZOB reduced-voltage starting motor 8, after being determined to start successfully by time-delay, the inspection of computer 6, K2 output 5 voltage signals disappear, K3 output 5 has voltage signal output simultaneously, and KM2 discharges, the KM3 adhesive, full voltage puts on motor 8, at this moment K1 output 5 voltage signals disappear, and KM1 discharges, and circuit enters normal operating condition.
Embodiment 3: when the utility model was used for reactor decompression starting threephase asynchronous 8, three pairs of outputs directly drove KM1.KM2.KM3 for 5 mouthfuls and finish starting, the operation of motor 8 and the overall process that stops.Output 5K1, K3 meet A.C. contactor KM1, KM3 respectively, when K1 has voltage signal output, the KM1 adhesive, power supply passes through reactor L reduced-voltage starting motor 8, after being determined to start successfully by time-delay, the detection of computer 6, K3 output 5 has voltage signal output, KM3 adhesive, full voltage put on motor 8, and at this moment K1 output 5 voltage signals disappear, KM1 discharges, and circuit enters normal operating condition.
