Description

It is a kind of can execute-in-place speed governing frequency converter automatic control system
Technical field
It the utility model is related to the design field of motor automatic electric drive control system.
Background technology
Frequency converter is to control the electric control appliance of ac motor by changing motor working power Frequency Patterns. This present industrial production speed progressively accelerates, required in higher and higher society that the use of frequency converter is also more and more frequent, existing The demand of field speed governing is also more and more.For the production environment that is relatively poor, floating dust is more, frequency converter is placed on existing , the use function of frequency converter is not only have impact on, and the service life of frequency converter is substantially reduced, in this case, remotely The mode of operation is just quite necessary.Automatically control and refer in the case where nobody directly participates in, utilize additional equipment Or device, some working condition or parameter for making machine, equipment or production process are automatically run according to predetermined rule.Production In activity, mechanical automatically controlling can reduce artificial use, reduce production cost, can also improve operating efficiency, increase Output, increase income;Automated condtrol adapts to the social current of modern society's rapid development.Manufacturer to production activity from The demand of dynamicization control is also increasingly fervent.
Utility model content
The utility model purpose is to be directed to problem above, there is provided one kind can execute-in-place, speed governing, can avoid frequency conversion Device installation influence at the scene its service efficiency, service life problem can execute-in-place speed governing frequency converter automatic control system.
The utility model includes major loop and control loop;The major loop includes three-phase breaker, potential regulator, change Frequency device, electrothermal relay, motor;The output end connection motor of the three-phase breaker;In the output end and motor of three-phase breaker Between be sequentially connected in series frequency converter, electrothermal relay;The inverter input accesses 380V power supplys by three-phase breaker;The electricity Position adjuster is serially connected in the given port of foreign frequency and the public port of analog input circuit of frequency converter;The electrothermal relay connects It is connected on the output end of frequency converter;
The control loop includes breaker, three selecting switch, hand switch knob, PLC automatic switch, KM contactors Coil, KA contactor coils, operation display lamp;Three selecting switch include the first make break contact, the second make break contact, the Three make break contacts;The output end of first make break contact is sequentially connected in series hand switch knob and KM contactor coils;Described The output end of two make break contacts is sequentially connected in series PLC automatic switch and operation display lamp;The output end string of 3rd make break contact Connect KA contactor coils;Electrically connected between the output end of the hand switch knob and the output end of PLC automatic switch;PLC is certainly Dynamic switch connects host computer and frequency converter by signal wire;The input of three selecting switch is connected with breaker;It is described The input connection 220V power supplys of breaker;
The output end of the three-phase breaker is also associated with variable frequency motor fan;The three-phase breaker output end with Fuse is set between variable frequency motor fan.
The utility model PLC automatically controls frequency converter drive motor start and stop after programming, by PLC, and Speed-regulating function is realized, in motor operation course, PLC can monitor the working condition of frequency converter, when a failure occurs, PLC in real time Being capable of output feedback signal, prompting fault message and motor out of service.The utility model can execute-in-place, speed governing, can keep away Exempt from frequency converter installation influenceing its service efficiency, service life at the scene.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
