Description
В самоходных землеройных машинах примен ют дизель-электрические приводы с асинхронным двигателем подачи, управл емым сигналами , пропорциональными току нагрузки электродвигател рабочего органа . Однако известные приводы подобного рода не позвол ют поддерживать оптимальный режим работы дизел .Self-propelled earthmoving machines use diesel-electric drives with an asynchronous feed motor controlled by signals that are proportional to the load current of the motor of the drive element. However, the known drives of this kind do not allow to maintain the optimum mode of operation of the diesel.
Предлагаемый дизель-электрический привод более совершенен, так как он позвол ет устранить этот недостаток. Это достигаетс тем, что магнитный усилитель, управл ющий дроссел ми насыщени , включенными в статорную обмотку двигател подачи, снабжен обмоткой отрицательной обратной св зи по напр жению, подключаемой к делителю напр жени , включенному на выход усилител .The proposed diesel-electric drive is more perfect, since it eliminates this drawback. This is achieved by the fact that the magnetic amplifier controlling the saturation throttles included in the stator winding of the feed motor is provided with a negative voltage feedback winding connected to a voltage divider connected to the output of the amplifier.
На чертеже изображена принципиальна схема предлагаемого привода .The drawing shows a schematic diagram of the proposed drive.
Привод содержит два асинхронных электродвигател : двигатель / подачи и двигатель 2 рабочего органа. В статорную цепь двигател / включены дроссели 3 насыщени , управл емые с помощью магнитного усилител 4. Магнитный усилитель 4, кроме выходной обмотки 5, имеет задающую обмотку 6, обмотку 7 отрицательной обратной св зи по напр жению и обмотку 8 обратной св зи по току двигател 2.The drive contains two asynchronous electric motors: the engine / feed and the engine 2 of the working body. The motor stator circuit / includes saturation throttles 3 controlled by a magnetic amplifier 4. Magnetic amplifier 4, besides the output winding 5, has a driver winding 6, negative voltage feedback winding 7, and motor current feedback winding 8 2
Задающа обмотка б присоединена через выпр мительный мост 9 к сети переменного тока землеройной мащины. Обмотка 7 питаетс посто нным током, пропорциональным току нагрузки двигател 2. Дл этой цели она подключена через выпр мительный мост 10 к трансформатору тока 11 в статорной цепи двигател 2. Обмотка 8 подключена к делителю 12 напр жени .The driver winding b is connected via a rectifying bridge 9 to an alternating current mains network of the earthmoving equipment. The winding 7 is supplied with direct current proportional to the load current of the engine 2. For this purpose, it is connected via a rectifying bridge 10 to the current transformer 11 in the stator circuit of the engine 2. The winding 8 is connected to the voltage divider 12.
При изменении величины сопротивлени плеч делител 12 измен етс величина отрицательной обратной св зи и ток подмагничивани дроссел 3 насыщени .When the value of the resistance of the shoulders of the divider 12 varies, the magnitude of the negative feedback and the bias current of the saturation thrusts 3 change.
