Description
такие же токи как и при соединении в звезду. При разомкнутом контакте роторна обмо.тка питаетс выпр млен ным током и двигатель работает в си хронном режиме с cosM 1 при номинальной нагрузке. Так как активное сопротивление -обмотки ротора достаточно мало, тре фазный мостовой выпр митель также р ботает в режиме короткого замыкани Коэффициент выпр млени по току В этом случае К 1,35. Дл полной компенсации реактивно мощности, потребл емой двигателем из сети, коэффициент трансформации ЭДС двигател должен быть Vt| где t-fff - номинальный коэффициент реактивной мсицности Дви:гател ; коэффициент выпр млени по току выпр мител . где 3л - среднее значение выпр м ,. ленного тока; действующее значение фа:з ного тока статора. Этому условию удовлетвор ет пода л ющее большинство серийно выпускаеьвдх асинхронных двигателей с фазны ротором мощностью 10 кВт и более. Если Kg то по обмотке ротора протекает выпр мленный ток, равный номинальному значению, при номинальной,нагрузке. Если Kg К, то параллельно выпр мительному устройству необходимоsame currents as when connected to a star. When the contact is open, the rotor winding is fed with rectified current and the engine is operating in synchronous mode with cosM 1 at rated load. Since the active resistance of the rotor winding is rather small, the three-phase bridge rectifier also operates in the short-circuit mode. The rectifier current ratio In this case, K 1.35. To fully compensate for the reactive power consumed by the motor from the network, the transformation ratio of the EMF of the motor must be Vt | where t-fff is the nominal coefficient of reactive power of the DVI: gatela; rectifier current rectifier. where 3L is the average value of straightening,. lex current; actual value of phase: stator current. This condition is satisfied by the overwhelming majority of mass-produced asynchronous motors with a phasic-rotor with a capacity of 10 kW and more. If Kg, then a rectified current, equal to the rated value, flows at the winding of the rotor at the rated load. If Kg K, then a parallel rectifier device is necessary
