Abstract
The utility model relates to a monitoring device for the production of a COREX slag vertical mill, in particular to a monitoring device for the operation state of a high-power motor of a COREX slag vertical mill, comprising a high-power motor (1) and a DCS control system (7), wherein the high-power motor (1) is connected in a current transformer (3) by a high- voltage cable (5) and the DCS control system (7) is input by a current transducer (4); a direct current (DC) signal converted by the current transducer (4) is 4-20mA; and the output information of the DCS control system (7) is displayed on the interface of a center control computer. After the technical scheme is adopted, an operator can directly monitor the operation condition of the high-power motor without going to a site and can go to the site to check and find problems if the current and the power have unusual fluctuations so that a small hidden trouble is effectively prevented from being turned into a large fault due to non-timely detection.
Description
(1) technical field
The utility model relates to the supervising device that a kind of COREX of being used for slag Vertical Mill is produced, particularly to the supervising device of COREX slag Vertical Mill heavy-duty motor running status.
(2) background technology
At present, the operation of COREX slag Vertical Mill the time be large power high voltage motor with 3550KW as main driving motor, in a single day powerful motor like this breaks down, it is extremely inconvenient to repair, and maintenance time is long, and output is had very big influence.Central control room and COREX slag Vertical Mill equipment distance are far away, the monitor mode of prior art is to have the special messenger that field apparatus is patrolled and examined in per 2 hours, the content that the scene is patrolled and examined is that the big motor of spot check is as good as sound or peculiar smell, can not see the situation of big motor internal, when having found that big motor has peculiar smell or different sound, also be late, need big motor has been keeped in repair.Prior art can not in time be found fault to COREX slag Vertical Mill heavy-duty motor monitor mode, especially can not find the operation conditions of big motor internal, and influence is in time handled and got rid of, and influence is produced.
(3) summary of the invention
The purpose of this utility model provides a kind of device that can monitor COREX slag Vertical Mill large power high voltage motor running status, before big motor breaks down, just can find in time that the abnormal conditions of big motor monitor.
For achieving the above object, the utility model is achieved by the following technical programs:
A kind of COREX slag Vertical Mill heavy-duty motor supervising device comprises heavy-duty motor and DCS control system, it is characterized in that, inserts current transformer on the high-tension cable of heavy-duty motor, through current transducer, and input DCS control system.
Further, the direct current signal that converts to of described current transducer is 4～20mA.
Further, the output information of described DCS control system is presented on the interface of central controlling computer.
Adopt the technical program, the direct current signal of 4～20mA that the induced current of the current transformer on the high-tension cable of big motor is converted to through current transducer is connected in the DCS control system, the DCS control system converts the direct current signal of 4～20mA to the ampere number, and this parameter is presented on the interface of central controlling computer.The DCS control system can also be carried out the current data that obtains the calculating of motor actual motion power, and this parameter is shown on the computer interface equally.
The DCS control system has been a comparative maturity, perfect computer control means, select with the relevant system parameters of input can obtain efficient system control and demonstration in requisition for information, but, this control system does not apply to the present technique field at home and abroad so far as yet, it is above-mentioned by artificial round production scene and periodically certain hour observation at interval of control room to remain employing, judge, notice, the mode of control, still there are many drawbacks, the utility model has adopted the DCS control system in the monitoring to COREX slag Vertical Mill heavy-duty motor first, filled up blank, brought obvious superiority in this field.
The beneficial effects of the utility model are that the employing the technical program makes operating personnel not spend the on-the-spot ruuning situation that just can monitor heavy-duty motor very intuitively.As find that electric current and power have unusual fluctuations, and can in time go to the scene to check, pinpoint the problems.Can effectively avoid like this allowing little hidden danger become the situation generation of major break down, improve production efficiency because patrol and examine untimely.
(4) description of drawings
Fig. 1 is the overall arrangement figure of the utility model COREX slag Vertical Mill heavy-duty motor supervising device.
Among the figure: 1, heavy-duty motor; 2, big motor high-voltage board; 3, current transformer; 4, current transducer; 5, high-tension cable; 6, central controlling computer; 7, DCS control system.
(5) embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed, complete explanation:
As shown in Figure 1:
A kind of COREX slag Vertical Mill heavy-duty motor supervising device comprises heavy-duty motor 1 and DCS control system 7, and heavy-duty motor 1 inserts current transformer 3 through high-tension cable 5, through current transducer 4, and input DCS control system 7.
The direct current signal that described current transducer 4 converts to is 4～20mA.
The output information of described DCS control system 7 is presented on the interface of central controlling computer 6.
Present embodiment is used for the device of COREX slag Vertical Mill large power high voltage motor running state monitoring, and by high-tension current inductor 3, current transducer 4, DCS control system 7 and central controlling computer 6 are formed.
During heavy-duty motor 1 operation, current transformer 3 on its high-tension cable 5 is sensed induced current, convert the direct current signal of 4～20mA to by current transducer 4, direct current signal transmits DCS control system 7, DCS control system 7 converts the direct current signal of 4～20mA to amperage again, and go out the power of large power high voltage motor by internal calculation, electric current and power number are presented on the interface of central controlling computer 6, operating personnel are monitored big motor easily, the discovery fault is in time got rid of, guarantee that equipment normally moves, effectively avoided allowing little hidden danger become the situation generation of major break down because patrol and examine untimely.
