которому преобразователь 5 измен ет напр - .жепие, приложенное к обмоткам 6 т говых двиг ателей. При этом ток обмоток т говых двигателей, измеренный датчиком 7, сравни- заетс с порогом порогового элемента 8. Вели нри пуске или торможении ток.вьпне юрога, то на выходе норогового элемента 8 по вл етс сигнал, который через преобразователь 5 измен е напр жение на т говых двигател х до тех нор, пока ток не снизитс до порога элемента 8, соответствующег о пре- .дельпым по сцеплению усили м электровоза. При нагреве обмоток т говых двигателей выше порога ограничени ограничителей 9 и 11 напр жение с датчика 10 нагрева через ограничитель 9 подаетс на уп- paв.Jl юн ий вход порогового элемента 8, снижа его порог и тем самым умепьп а ток т говых двигателей пропорционально темпе- |)атуре нагрева. Этим обеепечиваетс защита двигате.ей от перегрева в режимах пуска и гор.можени , когда ток двигателей близок к порогу элемента 8. Одновременно напр жение с датчика 10 пагрева через ограничитель 11 подаетс на вход формировател 2 заданной скорости, снижа заданную скорость пропорционально температуре нагрева. Этим обеепечиваетс защита двигателей от перегрева и заклипивание ротора двигател 3 режимах устаповивп:егос движе}1и , когда ток двигателей пиже порога элемента 8.

In this case, the current of the windings of the thrust motors, measured by the sensor 7, is compared with the threshold of the threshold element 8. When started or braked by the current, then at the output of the normal element 8, a signal appears through the converter 5 on traction motors until the current drops to the threshold of element 8, corresponding to the maximum coupling force of the locomotive. When the windings of the traction motors are heated above the threshold of limiting the limiters 9 and 11, the voltage from the heating sensor 10 through the limiter 9 is applied to the control Jl and the young input of the threshold element 8, reducing its threshold and thereby reducing the current of the motors in proportion to the temperature - |) heating ature. This protects the motor protection from overheating in start-up and deceleration modes when the current of the motors is close to the threshold of element 8. At the same time, the voltage from sensor 10 is supplied through limiter 11 to the input of the forming unit 2 of the set speed, reducing the set speed proportional to the heating temperature. This ensures the protection of motors from overheating and sticking of the rotor of the engine in 3 modes: setting the motor} 1, when the current of the engines is below the threshold of element 8. Decreasing the current and speed of movement leads to cooling of the engines to a temperature determined by my limit. 9 and II, after which the set speed becomes the command command and is restored to the G1) threshold and 1, 1a threshold of element 8.
