Description

Предметом насто щего авторского свидетельства  вл етс  устройство дл  возбуждени  синхронного генератора переменной частоты, например, служащего дл  питани  короткозамкнутых двигателей индивидуального привода роликов рольгангов.The subject of this author's certificate is a device for driving a synchronous variable frequency generator, for example, which is used to power short-circuited motors for the individual drive of the rolls of the roller tables.

В предлагаемом устройстве, согласно изобретению, применен, кроме обычного главного возбудител , вспомогательный возбудитель в виде индукционной машины, сид щей на одном с генератором валу и включенной первичной обмоткой на сеть с посто нной частотой, а вторичной, через выпр мители, - в цепь обмотки возбуждени  генератора. Такой вспомогательный возбудитель создает в генераторе дополнительное подмагничивание , количественно обратно пропорциональное частоте.In the proposed device according to the invention, besides the usual main exciter, an auxiliary exciter is applied in the form of an induction machine, sitting on the same shaft with the generator and the primary winding on the network at a constant frequency, and secondary, through rectifiers, in the winding circuit excitation of the generator. Such auxiliary pathogen creates additional bias in the generator, quantitatively inversely proportional to the frequency.

Сущность изобретени  по сн етс  чертежом, на фиг, 1 - 3 которого изображены три варианта электрической схемы предлагаемого устройства.The invention is illustrated in the drawing, FIGS. 1 to 3 of which show three variants of the electric circuit of the device proposed.

На чертеже имеютс  следующие обозначени : / - синхронный генератор переменной частоты, 2 - его основна  обмотка возбуждени , 3 - дополнительна  обмотка возбуждени , 4 - вспомогательный возбудитель в виде индукционной машины, первичной обмоткой приключенной к сети посто нной частоты, 5 - трехфазный выпр митель, к которому подводитс  ток от возбудител  4. 6- установочный реостат в цепи выпр мленного тока, 7-основной возбудитель генератора /, 5-его основна  обмотка возбуждени , 9 - дополнительна  обмотка возбуждени .The drawing contains the following designations: / - synchronous variable frequency generator, 2 - its main field winding, 3 - additional field winding, 4 - auxiliary agent in the form of an induction machine, the primary winding connected to a fixed frequency network, 5 - a three-phase rectifier, to which the current from the exciter 4 is supplied. 6 is the installation resistor in the rectified current circuit, the 7-main generator exciter /, the 5th main excitation winding, 9 the additional excitation winding.

В схеме по фиг. 1 возбудитель 4 (ноомальна  асинхронна  машина с фазовым ротором) питает через выпр митель 5 дополнительную обмотку возбуждени  3 генератора /.In the circuit of FIG. 1, a pathogen 4 (an ohm asynchronous machine with a phase rotor) feeds, through rectifier 5, an additional excitation winding 3 of the generator /.

В схеме по фиг. 2 имеет место бустерное (т. е. последовательное с каким-либо источником посто нного тока) включение выпр мител  5 возбудител  в цепь обмотки возбуждени  2 генератора 1. На схеме а, б- зажимы источника посто нного тока.In the circuit of FIG. 2, a booster (i.e., sequential with any DC source) switching-on of the exciter 5 of the exciter into the circuit of the excitation winding 2 of the generator 1 takes place. In diagram a, b are the terminals of the DC source.

В схеме по фиг. 3 возбудитель 4 питает (в отличие от схемы по фиг. 1) дополнительную обмотку возбуждени  9 основного возбудител  7 генератора 1.In the circuit of FIG. 3, the exciter 4 feeds (in contrast to the circuit in FIG. 1) an additional excitation winding 9 of the main exciter 7 of the generator 1.
