Abstract
A high-voltage frequency converter multimachine synchronization control device comprises a host frequency converter and at least one slave machine frequency converter. The host frequency converter and the slave machine frequency converter send torque currents of motors arranged on the host frequency converter and the slave machine frequency converter to master control equipment. The master control equipment sends a given frequency value to the host frequency converter. The host frequency converter sends the received given frequency value and the torque current of the host frequency converter to the slave machine frequency converter. By using the technical scheme, a principle is simple; fault shutdown of any frequency converter can be satisfied simultaneously; the rest of the frequency converters can be derated and belt shutdown is not caused.
Description
Technical field
The utility model relates to the synchronous control device of a kind of high voltage converter multimachine.
Background technology
At slope belt feeder application scenario, because factors such as strap length and field position restriction, cause a belt often to need a more than high-voltage motor to drag, will exist many high voltage converters to drag the situation of multiple electric motors this moment, and promptly high voltage converter need possess the multimachine synchronizing function.
At present, the synchronous many employings speed of high voltage converter multimachine, voltage, electric current are gathered simultaneously, calculate current motor torque electric current according to motor model, by guaranteeing the consistent multiple electric motors unanimity of exerting oneself that guarantees of torque current, reach synchronous purpose.But this kind method needs accurate picking rate, voltage, the magnitude of current, and the complexity of computing simultaneously needs high-end digital signal processor just can finish.In addition,, will cause the whole piece belt all to be shut down, client's output is exerted an influence if break down as the frequency converter of main frame.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, high voltage converter multimachine sync control device that synchronous effect is good.
For achieving the above object, the utility model is by the following technical solutions:
A kind of high voltage converter multimachine sync control device, it comprises a main frame frequency converter and at least one slave frequency converter, described main frame frequency converter and slave the frequency converter torque current of institute's translator separately send to main control device; Main control device sends to the main frame frequency converter with given frequency values, and given frequency values that the main frame frequency converter will receive and the torque current of self send to the slave frequency converter.
Described high voltage converter multimachine sync control device comprises two main frame frequency converters and ten slave frequency converters.
Adopt the utility model of technique scheme, principle is simple, can satisfy any frequency converter failure simultaneously and shut down, and all the other frequency converters can derate use, and can not cause belt to be shut down.
Description of drawings
Fig. 1 is a principle assumption diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of high voltage converter multimachine sync control device, it comprises a main frame frequency converter and at least one slave frequency converter, above-mentioned main frame frequency converter and slave the frequency converter torque current of institute's translator separately send to main control device; Main control device sends given frequency values to the main frame frequency converter through after judging, the main frame frequency converter according to given frequency conversion value adjustment at first do self-control; Torque current after the given frequency values that will receive then and self are regulated sends to the slave frequency converter.The slave frequency converter is regulated automatically according to the given frequency and the torque current that receive again, thereby realizes that multiple electric motors is synchronous.
Above-mentioned high voltage converter multimachine sync control device comprises two main frame frequency converters and ten slave frequency converters.
Claims (2)
1. high voltage converter multimachine sync control device, it comprises a main frame frequency converter and at least one slave frequency converter, it is characterized in that: described main frame frequency converter and slave the frequency converter torque current of institute's translator separately send to main control device; Main control device sends to the main frame frequency converter with given frequency values, and given frequency values that the main frame frequency converter will receive and the torque current of self send to the slave frequency converter.
2. high voltage converter multimachine sync control device according to claim 1 is characterized in that: described high voltage converter multimachine sync control device comprises two main frame frequency converters and ten slave frequency converters.
