Description
Известны устройства дл отработки интервалов времени, обратно-пропорциональных скорости движени полосы, в системе автоматического регулировани толщины проката листопрокатного стана.Devices are known for working out time intervals, inversely proportional to the speed of movement of the strip, in the system for automatically controlling the thickness of the rolling mill of the rolling mill.
В предлагаемом устройстве дл упрощени схемы последовательна цепочка из конденсатора и сопротивлени подключена к выходным шинам тахогенератора, предназначенного дл измерени скорости проката . Обмотка выходного магнитного усилител через диод подключена параллельно конденсатору.In the proposed device, to simplify the circuit, a series of capacitors and resistors is connected to the output buses of the tachogenerator, intended for measuring the rental speed. The winding of the output magnetic amplifier through a diode is connected in parallel to the capacitor.
Принципиальна схема устройства приведена на чертеже.A schematic diagram of the device is shown in the drawing.
Напр жение от тахогенератора 1 после замыкани контакта 2 и размыкани контакта 3 прикладываетс к конденсатору 4 через сопротивление 5. Параметры сопротивлени и конденсатора выбраны так, что изменение напр жени на обкладках конденсатора от нул до напр жени , равного приложенному в точках 6-7 устройства, происходит по линейному закону. С другой стороны врем нарастани тока в обмотке 8 магнитного усилител , котора включена через диод 9 параллельно конденсатору 4, от нул до тока срабатывани во много раз меньще времени зар да конденсатора 4. При указанных услови х врем срабатывани магнитного усилител обратно-пропорционально скорости движени полосы на листопрокатном стане.The voltage from tachogenerator 1 after closing the contact 2 and opening the contact 3 is applied to the capacitor 4 through the resistance 5. The parameters of the resistance and the capacitor are chosen so that the voltage on the capacitor plates varies from zero to a voltage equal to applied at points 6-7 of the device, occurs according to a linear law. On the other hand, the rise time of the current in the winding 8 of the magnetic amplifier, which is connected through diode 9 parallel to the capacitor 4, from zero to the operation current is many times less than the charging time of the capacitor 4. Under these conditions, the response time of the magnetic amplifier is inversely proportional to the speed of movement of the strip on the sheet rolling mill.
Описанное устройство проще известных и может найти применение в технике автоматизации производства на листопрокатных станах.The described device is easier known and can be used in the automation technology of production on sheet rolling mills.
