Description
Дл электрического торможени тепловозов с т говыми двигател ми последовательного возбуждени примен ют устройства, осугцествл ющие переключение корей двигателей в тормозном режиме на сонротнвлепи , а их обмоток возбуждени - на независимое питание от генератора.For electric braking of diesel locomotives with a traction motor of sequential excitation, devices are used that susceptible switch the engine koreas in brake mode to sonrot, and their excitation windings to an independent power supply from the generator.
Однако эти устройства не обеспечивают получени оптимального тормозного усили при различных скорост х движени тепловоза и не позвол ют ограничить ток в кор х двигателей.However, these devices do not provide optimal braking force at various speeds of the locomotive and do not allow the current to be limited in the engine bar.
Предлагаемое устройство более совершенно, так как оно лишено указанных недостатков.The proposed device is more perfect, since it is devoid of these shortcomings.
Это достигаетс тем, что в цепь питани обмотки возбуждени генератора введена отрицательна обратна св зь по тормозному току.This is achieved by introducing negative braking current feedback into the power supply circuit of the generator excitation winding.
На чертеже изображена принципиальна схема предлагаемого устройства .The drawing shows a schematic diagram of the proposed device.
В тормозном режиме кори двигателей /, 2, 3, 4, 5, 6 переключаютс на сопротивлени 7, а обмотки возбуждени 8 на независимое питание о г генератора 9. В цепь обмотки возбуждени W включаетс часть сопротивлени 7 динамического торможени , чем создаетс жестка отрицательна обратна св зь по току динамического торможени .In the brake mode, the motor measles I, 2, 3, 4, 5, 6 are switched to resistance 7, and the excitation winding 8 is independently supplied to the generator 9. The excitation winding W includes a part of dynamic braking resistance 7, which creates a hard negative reverse dynamic braking current coupling.
