Description
10.Устройство содержит также другой диод10. The device also contains another diode.
11,шунтирующий последовательно соединенные разделительный диод 3, импульсный преобразователь 4 и обмотку 2 возбуждени т гового электродвигател .11, shunting the series-connected separation diode 3, the pulse converter 4 and the excitation winding 2 of the traction motor.
Устройство работает следующим образом.The device works as follows.
Переход в режим рекуперативного торможени при последовательном возбуждении т гового электродвигател осуществл етс путем одновременного отпирани дополнительного тиристора 10 и импульсного преобразовател 4. Ток нарастает по цепи: обмотка 1 кор электродвигател , дополнительный тиристор 10, импульсный преобразователь 4, обмотка 2 возбуждени электродвигател и диод 1.1. При запирании импульсного преобразовател 4 и, следовательно, дополнительного тиристора 10 ток обмотки 1 кор протекает через источник 7 питани , ток обмотки 2 возбуждени и замыкаетс через электрический вентиль 6. Так как отпадает необходимость JB реверсировании обмотки 1 кор (или обмотки 2 возбуждени ), реализуетс бесконтактный переход в режим рекуперации . Разделение обмоток кор и возбуждени исключает возможность срыва режима импульсной рекуперации и позвол ет расширить диапазон скоростей торможени , который определ етс параметрами т гового электродвигател и напр жением источника питани . Тиристор 8 обеспечивает форсировку самовозбуждени т гового электродвигател при низких скорост х начала торможени .Switching to regenerative braking mode with sequential excitation of the traction motor is performed by unlocking an additional thyristor 10 and a pulse converter 4 at the same time. When the pulse converter 4 and, therefore, the additional thyristor 10 is locked, the current of the winding 1 core flows through the power supply 7, the current of the excitation winding 2 and closes through the electric valve 6. Since JB does not need to reverse the winding of the 1 core (or excitation winding 2), contactless transition to recovery mode. Separating the windings of the core and excitation eliminates the possibility of breaking the pulse recovery mode and allows you to expand the range of braking speeds, which is determined by the parameters of the traction motor and the voltage of the power source. The thyristor 8 provides forcing the self-excitation of the traction motor at low rates of the start of braking.
