Description

Предлагаетс  новый способ возбуждени  синхронных машин, при котором в качестве возбудител  вместо машины посто нного тока используетс  бесколлекторна  многофазна  машина переменного тока. Якорь возбудител  л естко св зан с валом синхронной машины, а его обмотка соедин етс  с обмоткой возбуждени  синхронной машины через твердые выпр мители (селеновые, купроксные и другие), смонтированные на валу агрегата и вращающиес  вместе с ним.A new method of exciting synchronous machines is proposed, in which a brushless multiphase AC machine is used as an exciter instead of a direct current machine. The driver's anchor is rigidly connected to the shaft of the synchronous machine, and its winding is connected to the excitation winding of the synchronous machine through solid rectifiers (selenium, cuprox, etc.) mounted on the shaft of the unit and rotating with it.

Преимуществом предлагаемой системы  вл етс  отсутствие коллектора и контактных колец, а также возможность использовани  в системе возбуждени  весьма низких напр жений.The advantage of the proposed system is the absence of a collector and contact rings, as well as the possibility of using very low voltages in the excitation system.

На чертеже изображена одна из возможных схем предлагаемого способа возбуждени  синхронных машин.The drawing shows one of the possible schemes of the proposed method for driving synchronous machines.

Обмотка возбуждени  синхронной машины / св зана через твердые выпр мители 2 с многофазной обмоткой 3  кор  возбудител . Обмотка возбуждени  4 возбудител  питаетс  любым известным способом.The excitation winding of the synchronous machine / is connected via solid rectifier 2 with a multiphase winding 3 core of the exciter. The field winding 4 of the driver is powered by any known method.

При низком напр жении число фаз обмотки 3 может быть значительно увеличено и, в частности, может быть сделано равным числу пазов  кор  возбудител .At low voltage, the number of phases of the winding 3 can be significantly increased and, in particular, can be made equal to the number of slots of the exciter core.

Предмет изобретени Subject invention

Синхронна  машина, в которой расположенна  на роторе обмотка возбуждени  питаетс  через укрепленные на враи ающейс  части машины твердые выпр мители (купроксные, селеновые и другие) от низковольтной многофазной обмотки переменного тока, также укрепленной на валу машины, отличающа с  тем, что означенна  обмотка переменного тока выполнена как  корна  обмотка отдельной мащины переменного тока-возбудител , сид щего на валу синхронной машины.A synchronous machine in which the field winding is located on the rotor is powered by solid rectifiers (cuprox, selenium and others) mounted on the rotating parts of the machine from the low-voltage multi-phase AC winding, also mounted on the machine shaft, which is marked as AC winding A separate winding of an alternating-current exciter, sitting on the shaft of a synchronous machine, is designed as a root winding.
