Abstract
The utility model discloses a kind of barn motor monitoring system; barn AC-powered circuit connects motor through isolating switch; described isolating switch connects motor through contactor, motor protecter, and the relay K M1 controlling described contactor break-make connects with button SB2 and accesses power circuit.The utility model supervisory system decreases maintenance of equipment cost, reduces labour intensity, and reduces the economic loss brought because of device fails, adds the personnel safety factor to operator.
Description
Technical field
The utility model relates to machine field, is especially provided with a kind of system for monitoring motor.
Background technology
Need to toast in leaf tobacco production process, and motor is all installed in barn, because machine operation environment is noisy, usually cannot Timeliness coverage when motor breaks down, thus affect quality of tobacco and equipment life, specifically, there is following defect in current barn motor device: 1: in circuit phase shortage, motor overload situation, motor easily burns, and maintenance of equipment cost increases; 2: certain motor is because knowing after disorderly closedown that to cause tobacco leaf to bake bad in barn, loses huge; 3: directly close separated motor power supply low to personnel safety factor; 4: whether normally running to observe motor, the inspection of many rounds be carried out, add labour intensity.
Utility model content
Technical problem to be solved in the utility model realizes a kind of reaction electric machine operation state that can be direct, quick, sensitive, and can carry out the supervisory system of alarm when breaking down.
To achieve these goals; the technical solution adopted in the utility model is: barn motor monitoring system; barn AC-powered circuit connects motor through isolating switch; described isolating switch connects motor through contactor, motor protecter, and the relay K M1 controlling described contactor break-make connects with button SB2 and accesses power circuit.
Comprise with the circuit of button SB2 series circuit parallel connection with described relay K M1: the circuit that normally closed button SB3 connects with the relay FM controlling motor protecter break-make, and state display lamp.
The control end loop of described contactor is provided with four interlock contact-making switches, one of them normally opened contact is in parallel with button SB2, a normally opened contact is connected with state display lamp, another normally opened contact stops display lamp with normally closed scram button SB4 and urgency and connects, and normally closed contact is connected with the relay K A1 controlling warning device work.
One of them normally opened contact of described series connection, normally closed scram button SB4, with anxious stop display lamp and warning device and with one of them normally opened contact relay K A1 connected, parallel with one another, and parallel circuit access is through the DC circuit of transformer, rectifier process.
Described barn is the barn of baking tobacco leaves.
The utility model supervisory system decreases maintenance of equipment cost, reduces labour intensity, and reduces the economic loss brought because of device fails, adds the personnel safety factor to operator.
Accompanying drawing explanation
Below the content that width accompanying drawing every in the utility model instructions is expressed is briefly described:
Fig. 1 is supervisory system circuit theory diagrams.
Embodiment
Barn motor monitoring system is used for the barn of baking tobacco leaves; known see Fig. 1; barn AC-powered circuit connects motor through isolating switch, and wherein isolating switch connects motor through contactor, motor protecter, and the relay K M1 controlling above-mentioned contactor break-make connects with button SB2 and accesses power circuit.Pick out a road zero line and live wire access panel box in AC-powered circuit, the live wire circuit of access panel box is in series with normally closed button SB1.
Supply line is parallel with following device in panel box, the normally closed point of the relay K M1 of series connection, FM and button SB2, the circuit that normally closed button SB3 connects with the relay FM controlling motor protecter break-make, and state display lamp.
The control end loop of contactor is provided with four interlock contact-making switches, and one of them is normally closed contact, and other three is normally opened contact, and one of them normally opened contact is in parallel with button SB2, and another normally opened contact is connected with state display lamp.
When occur in circuit phase shortage, short circuit or motor overload time, ac contactor coil voltage is cut off in the normally closed disconnection of comprehensive protector of motor FM.Press SB2 button, contactor KM1 adhesive self-locking.State display lamp is green, represents that motor normally works when lighting.
The power supply quoted through panel box supply line is delivered to line concentrating case through transformer and rectifier, line concentrating case supply line is parallel with following device, the normally closed scram button SB4 connected, another normally opened contact and urgency stop display lamp, warning device, and the relay K A1 of the normally closed contact of series connection and the work of control warning device.
Contactor disconnects, then motor is out of service, and now red urgency is stopped display lamp and lighted, and contactor KM1 latching point disconnects, and KM1 normally closed contact is connected, and relay K A1 coil obtains telegram warning lamp HR buzzing and reports to the police.
During system works, the circuit breaker Q F1 that closes presses start button SB2 motor and brings into operation.This system cuts off AC contact electric power by motor protecter, thus reaches the effect of protection motor
Above by reference to the accompanying drawings to invention has been exemplary description; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
