Abstract
The invention discloses a control system that is suited for various dynamos. It includes combination switch, change over switch, stop button, start button, and intermediate relay. The combination switch has an end connecting to the middle between change over switch and stop switch, and the other end connects to the input end of PLC through intermediate relay. The invention output the field signal to PLC control system for center controlling room to make PLC control system acquire field situation and improving automatic degree. The combination switch is located in field control box to avoid the happening of accidents. It decreases the usage of cable, lowers cost, and improves accuracy.
Description
Technical field
The present invention relates to a kind of control system, be applicable to the Motor Control of various engineerings, relate in particular to and a kind of alumina producer is adopted computer-controlled control box electric-control system.
Background technology
In the existing alumina producer production technology, be that employing machine side and central control room (CCR) two places are controlled production, need staff's manual operation, control is inconvenient, and automaticity is low.Combined switch SA is arranged in the central control room (CCR), because field condition is not very understood, when motor is controlled, is easy to have an accident.And the cost of existing control system is higher.
Summary of the invention
The present invention is exactly the electric-control system that a kind of control box is provided in order to solve the problems of the technologies described above, and purpose is to reduce the cost of control system, improves automaticity, improves the degree of accuracy of system, avoids the generation of accident as far as possible.
To achieve these goals, the present invention is achieved in that a kind of electric-control system of control box, it comprises combined switch SA, switch SE, stop button SS, start button SF, auxiliary reclay KS, wherein combined switch SA also be provided with between an end and switch SE and the stop button SS be connected, circuit that the other end is connected with PLC control system input end by auxiliary reclay KA3, combined switch SA also is connected with contactor coil KM with start button SF.
Described combined switch SA is arranged in the control box.
Described auxiliary reclay KS is connected with the output terminal of PLC control system, and simultaneously, the auxiliary contact of KS auxiliary reclay is connected with the KM contactor coil.
Advantage of the present invention and effect are as follows:
The present invention combined switch SA is provided with between one group of one end and switch SE and the stop button SS be connected, circuit that the other end is connected with the PLC input end of central control room (CCR) by auxiliary reclay KA3, the signal at scene is exported to the PLC control system of central control room (CCR), make the PLC control system can understand field conditions constantly, make and produce interlock, PLC centralized control, improved the automaticity of system.The SA combined switch is arranged in the field control case, makes the other test run of staff's machine at the scene or during maintenance, the staff of main control room or computing machine all can not be controlled this TV station motor, so avoided the generation of accident, reach the order of safety in production.The present invention has reduced the use amount of cable, has improved degree of accuracy, has reduced cost.

Fig. 1 is a circuit diagram of the present invention.
Embodiment
A kind of electric-control system of control box, it comprises combined switch SA, switch SE, stop button SS, start button SF, auxiliary reclay KS, wherein combined switch SA also be provided with between an end and switch SE and the stop button SS be connected, circuit that the other end is connected with PLC control system input end by auxiliary reclay KA3, combined switch SA is arranged in the control box, and auxiliary reclay KS is connected with the output terminal of PLC control system.
Below in conjunction with Fig. 1 concrete structure of the present invention is described in detail as follows, but protection scope of the present invention is not subjected to
Embodiment limits.
As shown in Figure 1, its wiring is as follows: 1. combined switch SA is connected with 23 of start button SF, 27 of start button SF are connected with contactor KM coil, 2. combined switch SA is connected with 21 of stop button SS, 3. combined switch SA is connected with 29 of auxiliary reclay KS, 27 of auxiliary reclay KS are connected with contactor coil KM, 4. combined switch SA is connected with 19 of stop button SS, and be connected with 19 of switch SE, 17 of switch SE with electrothermal relay KH 17 are connected, 7. combined switch SA is connected with 31 of auxiliary reclay KA3, and 8. combined switch SA is connected with 19 of stop button SS, and be connected with 19 of switch SE.
Principle of work of the present invention is as follows:
As shown in Figure 1; when combined switch SA chooses a left side 45 when spending; the 1. point of combined switch SA and 2. 2 connections, in this position, the other test run of the machine that is; maintenance mode; press start button SF this moment, contactor KM coil is connected charged, and major loop contactor KM contact is by adhesive; motor is charged to be started; in the time of need shutting down after the electric motor starting running, press stop button SS, contactor KM coil blackout; major loop KM probe of contactor is opened; motor outage is shut down, if when finding that when debugging or maintenance motor or machine operation are undesired, utilizes switch SE in time to cut off the electricity supply; contactor KM coil blackout, the motor outage is shut down.
When combined switch SA chooses right 45 when spending; 3. the point of combined switch and 4. put two connections; 7. the point of combined switch and 8. put two connections; in this position; be and produce interlock or PLC centralized control; the computer controlled automatic mode, this moment, auxiliary reclay KA3 was charged, and this motor is allowed to produce interlock or PLC centralized control; computer controlled automatic mode signal has inputed to computing machine; this moment, this motor entered system, and follow procedure is worked automatically; when PLC exports; auxiliary reclay KS coil is charged, its auxiliary contact KS adhesive, and contactor KM coil is connected charged; major loop KM probe of contactor is by adhesive; motor is charged to be started, otherwise when PLC did not export, this motor outage was shut down.
