Описываемое усТЮГютво состоит и:, тех же рабочих органов, но эпектрнческа схема cio изменена так, что в период равномерного двнлсени нривода мотор-генератор работает в качестве возбудител основного асинхронного двигате.т , т. е. переводит его в синхронный режим, вследствие чего увеличиваетс жесткость характеристик нривода в неркод paBiiOMcpnoro хол.а н новынааетс коэффиниент мощности установки .The described condition is composed of and :, the same working bodies, but the cio circuitry is modified so that during a period of uniform movement of the drive, the motor-generator works as the main induction motor driver, i.e., it translates into synchronous mode, as a result The rigidity of the characteristics of the drive in nekrod paBiiOMcpnoro cold. It is newly adjusted installation power factor.
На чертеже приведена э.чектрическа схема устройства.The drawing shows the electrical circuit of the device.
Асинхронный мотор / с помощью шестерен 2 жестко св зан с тормозны:- , генератором 3 посто нного тока , облготка возбуж.аени которого ннтаетс от генератора -4. ,;-генератор 54 leзaвиcи.ь;.i возбужД:чн1 (м, осуществл емым через электромаин1нный усилитель , в мо .мент ра.згона основного двигател рабо1.ает вхолостую. При достижении мотором / номинальной скорости генератор 4 возбу сдаетс и с номонл,ью контакторов ФО и СХ включаетс в день ротора асинхронного двигагеч . При этом сопротивлени , вк.чючеиные в цепь ротора, отключаютс с по.мощью контакторов СХО.The asynchronous motor / with the help of gears 2 is rigidly connected to the brakes: -, by the generator 3 of direct current, which is excited by the generator -4. ,; - generator 54 lezavisi.b; .i excitation: pn1 (m, carried out through an electromagnet amplifier, can be idle in the driving power of the main engine. When it reaches the motor / nominal speed, the generator 4 is expelled and During the operation of the FD and CX contactors, the rotor of the asynchronous motor is switched on the day. In this case, the resistors connected to the rotor circuit are disconnected with the help of the CXO contactors.
Получив возбуждение от генератора 4, мотор / синхронизируетс и привод начинает работать со строго посто нным числом оборотов.After receiving the excitation from the generator 4, the motor / is synchronized and the drive starts to work at a strictly constant number of revolutions.
При уменьщении чиста оборотов двигател отк.пючаютс контакторыWhen the engine speed is reduced, the contactors are disconnected.
