Description

Изобретение относитс  к регулируемым электроприводам посто нного тока с ЭоПектрическим двигателем , питаемым через неуправл емые (например, полупроводниковые) вентили от многофазиого трансформатора с секционированной вторичной обмоткой, выводы которой переключаютс  коммутационными аппаратами (например, контакторами ) дл  получени  р да ступеней питающего напр жени  и, соответственно , р да скоростей привода.This invention relates to variable speed electric drives with an EoPectric motor, fed through unmanaged (e.g., semiconductor) valves from a multiphase partitioned secondary winding transformer, the outputs of which are switched by switching devices (e.g. contactors) to obtain a number of supply voltage stages accordingly, p yes drive speeds.

В предложенном приводе, с целью увеличени  числа ступеней при минимальном количестве коммутационной аппаратуры, выводы у разных фаз вторичной обмотки трансформатора расположены иесимметричио , и вентили могут подключатьс  к ним в различных комбииаци х.In the proposed drive, in order to increase the number of stages with the minimum number of switching equipment, the outputs of the different phases of the secondary winding of the transformer are located iesymmetrically, and the valves can be connected to them in various combinations.

На чертеже показана схема предложенного электропривода с включением от трехфазного трансформатора .The drawing shows a diagram of the proposed electric drive with the inclusion of a three-phase transformer.

Дл  регулировани  напр жени  двигател  Д секции вторичной обмотки трансформатора Т подключают контакторами Ке к неуправл емым вентил м В.To regulate the motor voltage, the secondary section of the transformer T is connected by contactors Ke to uncontrolled valves B.

Дл  трехфазной схемы при шести контакторах можно получить 26ступеней напр жени , что достигаетс  несимметричным расположеиием выводов у разных фаз вторичной обмотки трансформатора Т, подключаемых к вентил м в различных комбинаци х.For a three-phase circuit with six contactors, voltage stages can be obtained, which is achieved by the asymmetrical arrangement of the leads at different phases of the secondary winding of the transformer T connected to the valves in various combinations.

Предмет изобретени Subject invention

Регу.Шруемый электропривод носто ниого тока с электрическим двигателем, питаемым через неуправл емые (например, иолуироводииковые ) вентили от многофазного трансформатора с секционированной вторичнойобмоткой, выводы которой переключаютс  коммутационными аппаратами (например,контакторами ) Д.ЛЯ получени  р да ступеней питающего напр жени  и, соответственно , р да скоростей привода , отличающийс  тем, что. с целью увеличени  числа ступеней при минимальном количестве коммутациоиной аппаратуры, выводы у разных фаз вторичной обмотки трансформатора расположеиы несимметрично и вентили могут подключатьс  к ним в различных комбинаци х .An electric current driven motor with an electric motor fed through uncontrolled (for example, iLiViODiikovye) valves from a multiphase partitioned transformer with a secondary winding, the outputs of which are switched by switching devices (for example, contactors). respectively, a number of drive speeds, characterized in that. in order to increase the number of stages with a minimum amount of switching equipment, the outputs of different phases of the secondary winding of the transformer are asymmetrical and the valves can be connected to them in various combinations.
