Description
Известны способы подавлени переменных составл ющих тока в обмотках управлени трехфазного магнитного усилител с самонасыщением , основанные па использовании дополнительных индуктпвностей s цепи обмоток управлени и П1унтировании этих обмоток селеновыми выlIp митevIЯ и и емкост ми.Methods are known for suppressing the variable components of the current in the control windings of a three-phase magnetic amplifier with self-saturation, based on the use of additional inductance s of the control winding circuit and on unwinding these windings with selenium thermal capacitances and capacitances.
Недостатком этих способов вл етс возникновение в магнитном усилителе релейного эффекта, заключающегос в скачкообразном изменении выходного тока магни,тного усилител при плавном изменении тока в обмотках управлени , что объ сн етс вли нием паразитных переменных составл ющих тока, не скомпенсированных в обмотках магнитного силител .The disadvantage of these methods is the appearance of a relay effect in a magnetic amplifier, which consists in a stepwise change in the output current of a magnesium amplifier when the current changes smoothly in the control windings, which is explained by the influence of the parasitic variable components of the current that are not compensated in the windings of the magnetic silicon.
Дл устранени релейного эффекта в описываемом способе применена трансформаторна обратна св зь между обмотками управлени магнитного усилител .To eliminate the relay effect in the described method, transformer feedback is applied between the control windings of the magnetic amplifier.
На чертеже представлена принципиальна схема соедипени обмоток управлени магнитного усилител в известной системе возбулчдени двигател клети стана непрерывного проката с гибкой отрицательной трансформаторной св зью между обмотками управлени усилител .The drawing shows a schematic diagram of the connection of the control windings of the magnetic amplifier in the known system of excitation of the engine of the stand of the continuous rolling mill with a flexible negative transformer connection between the control windings of the amplifier.
В этой системе возбуждение двигател Д осуществлено током вых от магнитного усилител с внутренней обратной св зью. Усилитель состоит из двух каскадов усилени : промежуточного ,тпого усилител ПМУ и главного магнитного усилител PAW. Кроме того, исиользуетс магнитный усилитель У /Утг возбуждени тахогенератора.In this system, the excitation of the motor D is carried out by the current output from the magnetic amplifier with internal feedback. The amplifier consists of two stages of amplification: an intermediate amplifier, a PMU amplifier, and a PAW main magnetic amplifier. In addition, a magnetic amplifier U / Utg excitation of the tachogenerator is used.
Дл осуществлени предлагаемого способа трансформатор дл соединени обмоток управлени МУ подключаетс к зажимам 1-4. Он представл ет собой обычный трансформатор с сердечником из транTo implement the proposed method, a transformer for connecting the control windings of the MC is connected to terminals 1-4. It is a conventional transformer with a trans-core.
