Every frequency converter 3 is all that power supply is converted to DC voltage by " rectifier ", is then converted to exchange by " inverter " again
Power supply is carried out at the same time pressure regulation, frequency modulation rate and then realizes that the speed-regulating function to motor is whole since each frequency converter 3 also needs to connection one
Device is flowed, it is more to also result in internal rectifier.The major defect of this motor speed control device used in now is：1) become
The circuit that frequency device uses is more, and power consumption is larger；2) multiple frequency converters and rectifier are larger to the occupancy in space in electronic box；3)
Using multiple rectifiers, cost is higher.
Utility model content
In consideration of it, the utility model provides and a kind of can reduce energy consumption, reduces space hold and reduce the application of cost
In the motor speed control device of wire drawing machine.
For this purpose, the utility model provides a kind of motor speed control device applied to wire drawing machine comprising an at least frequency conversion
Mechanism, frequency conversion mechanism include multiple frequency converters arranged side by side, and gapless is arranged between two adjacent frequency converters, frequency converter connection
Motor, motor connect drawing block, and frequency converter is also connected to by first line on DC bus, and it is whole that DC bus is connected to one
It flows on device, rectifier connects power supply.
Further, above-mentioned multiple frequency converters are connected in parallel to a DC bus.
Further, there is shell, shell to seal multiple frequency converters simultaneously for above-mentioned frequency conversion mechanism.
Further, above-mentioned rectifier passes through 380V connection power supplys.
Further, above-mentioned power supply is three phase mains.
A kind of motor speed control device applied to wire drawing machine provided by the utility model, is mainly utilized common DC bus
The principle of frequency converter, the principle are mainly：1 " big rectifier " carries out rectification, is converted to DC power supply, is then assigned to " more
A inverter " carries out inversion；In this way, traditional " multiple rectifiers " just merges for a big rectifier, inverter conduct
Frequency converter equally independently uses, and function and traditional frequency conversion device compare and remain unchanged；Thus, the utility model phase
It is mainly had the following advantages compared with the prior art：
1) energy consumption is saved, the motor in generating state can will use on electric energy feedback to DC bus for other motors,
It thus can be with power saving；
2) installation space is saved, since common DC bus frequency converter can be mounted side by side, while multiple rectifiers are combined into one
It is a, because without occupying more installation space；
3) purchase cost is reduced, common DC bus frequency converter is declined due to incorporating more rectifiers, cost；
Based on the above advantage, since the frequency converter quantity on wire drawing machine is more, thus the motor speed control device of the utility model
It is more suitable for the use of wire drawing machine compared to the prior art.
