Description

Известны электромагнитные корректоры напр жени  синхронных генераторов, содержащие измерительный элемент, выполненный в виде линейного и нелинейного дросселей, выходы которых через выпр мители включены на обмотки управлени  трехфазного магнитного усилител  с внутренней обратной св зью.Electromagnetic voltage corrections for synchronous generators are known, containing a measuring element made in the form of linear and nonlinear chokes, the outputs of which are connected via rectifiers to the control windings of a three-phase magnetic amplifier with internal feedback.

Предложенное изобретение позвол ет уменьшить габариты и одновременно увеличить чувствительность электромагнитного корректора напр жени  путем выполнени  измерительной и усилительной частей корректора в одном устройстве.The proposed invention allows to reduce the dimensions and at the same time increase the sensitivity of the electromagnetic voltage corrector by performing measurement and amplifying parts of the corrector in one device.

Это достигаетс  тем, что на магнитопровод магнитного усилител  укладываютс  две дополнительные трехфазные обмотки, одна из которых соедин етс  открытым треугольником и работает в качестве нелинейного элемента, а втора  соедин етс  звездой и работает как линейный элемент. Выходы указанных дополнительных обмоток через выпр мители присоединены к входам обмоток управлени  магнитного усилител , намагничивающие силы которых направлены встречно.This is achieved by stacking two additional three-phase windings on the magnetic core of the magnetic amplifier, one of which is connected by an open triangle and works as a nonlinear element, and the second is connected by a star and works as a linear element. The outputs of these additional windings through the rectifiers are connected to the inputs of the control windings of the magnetic amplifier, the magnetizing forces of which are directed oppositely.

На чертеже изображена схема предлагаемого корректора, который выполн етс  на базе трехфазного магнитного усилител  с внутренней обратной св зью. Вход корректора /, 2, 3 подключаетс  на регулируемое напр жение генератора, а выход 4, 5, 6-через выпр митель 7 включен на обмотку 8 управлени  магнитного усилител . На каждую фазу магнитного усилител  уложены две дополнительные обмотки 9 к 10 переменного тока. Обмотки эти эквивалентны линейному и нелинейному элементам и соединены соответственно в звезду и открытый треугольник.The drawing shows a diagram of the proposed equalizer, which is performed on the basis of a three-phase magnetic amplifier with internal feedback. The input of the corrector, 2, 3 is connected to an adjustable voltage generator, and the output 4, 5, 6 through rectifier 7 is connected to the winding 8 of the control of the magnetic amplifier. For each phase of the magnetic amplifier, two additional windings of 9 to 10 AC currents are laid. These windings are equivalent to linear and non-linear elements and are connected, respectively, into a star and an open triangle.

При изменении напр жени  питани  магнитного усилител , т. е.When the voltage of the magnetic amplifier is changed, i.e.

при изменении напр жени  генератора и неизменном подмагничиванииwhen the generator voltage changes and the bias is constant

усилител , выходной ток обмотки .9, включенной на эквивалентную наamplifier, the output current of the winding .9 included on the equivalent on
