Description
(5А) АСИНХРОННЫЙ ВЕНТИЛЬНЫЙ КАСКАД(5A) ASYNCHRONOUS VENTILARY CASCADE
II
Изобретение относитс к электротехнике и может быть использовано дл регулировани частоты вращени различных производственных механизмов .The invention relates to electrical engineering and can be used to control the rotational speed of various production mechanisms.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс асинхронный вентильный каскад, содержащий асинхронный электродвигатель с трехфазным мостовым выпр мителем в цепи ротора, который через сглаживающий дроссель соединен с инвертором, выход которого соединен с одними выводами трехфазного согласующего трансформатора l.Closest to the invention, the technical essence and the achieved result is an asynchronous valve cascade containing an asynchronous motor with a three-phase bridge rectifier in the rotor circuit, which is connected to an inverter through a smoothing choke, which is connected to one of the three-phase matching transformer l terminals.
Однако известное устройство обладает низкой надежностью за счет того , что индуктивность сглаживающего дроссел составл ет трех-п тикратную величину от индуктивности асинхронного двигател .However, the known device has low reliability due to the fact that the inductance of the smoothing throttle is three to five times the value of the induction of an induction motor.
Целью изобретени вл етс повышение надежности асинхронного вентильного каскада.The aim of the invention is to increase the reliability of the asynchronous valve cascade.
Указанна цель достигаетс тем, что в асинхронном вентильном каскаде вторична обмотка согласующего трансформатора снабжена средними выводами и в каскад введены два тиристорных ключевыхблока, блок управлени и датчик частоты вращени This goal is achieved by the fact that in the asynchronous valve cascade the secondary winding of the matching transformer is equipped with average leads and two thyristor key blocks are inserted in the cascade, the control unit and the rotational speed sensor
to электродвигател , установленный на одном валу с электродвигателем, причем выход датчика частоты вращени электродвигател соединен с входом блока управлени , выходы которого motor mounted on the same shaft with the electric motor, and the output of the rotational speed sensor of the electric motor is connected to the input of the control unit, the outputs of which
