Description
Предметом насто щего авторского свидетельства вл етс схема рекуперативного торможени группы т говых двигателей с возбудителем в виде машины типа „Метадин. Одна из обмоток этого возбудител в предлагаемой схеме подключаетс к сети последовательно с корной обмоткой одного из т говых двигателей, а друга -низковольтна обмотка используетс дл питани обмотки возбуждени т говых двигателей. Така схема имеет целью обеспечить получение необходимой при т ге и рекуперации автоматической характеристики.The subject of this author's certificate is the regenerative braking scheme of a group of traction engines with a causative agent in the form of a machine of the type “Metadine. One of the windings of this exciter in the proposed scheme is connected to the network in series with the core winding of one of the traction motors, and the other, the low-voltage winding is used to power the excitation winding of the traction motors. Such a scheme is intended to ensure that the automatic characteristics required for traction and recovery are obtained.
Сущность изобретени по сн етс чертежом, на фиг. 1 которого изображена принципиальна четырехмоторна электрическа схема предлагаемого устройства при последовательном соединении групп т говых двигателей, а на фиг. 2-при параллельном соединении.The invention is illustrated in the drawing; in FIG. 1 of which a schematic four-motor electrical diagram of the proposed device is depicted in series connection of groups of traction engines, and FIG. 2-in parallel connection.
Принцип работы схемы заключаетс в следующем.The principle of operation of the circuit is as follows.
Обмотки возбуждени 7, 2, 3, 4 т говых двигателей М, М, М и M подключены к щеткам 6 и 7 метадина 5, приводимого во вращение шунтовым двигателем 12. Метадин 5 имеет дваThe excitation windings 7, 2, 3, 4 of the thrust engines M, M, M and M are connected to brushes 6 and 7 of methadine 5, driven by the rotation of the shunt motor 12. Metadin 5 has two
коллектора и две обмотки-одна дл напр жени в контактном проводе со щетками 8 и 9, а друга -низкого напр жени дл питани обмоток возбуждени т говых двигателей.a collector and two windings, one for the voltage in the contact wire with brushes 8 and 9, and the other for a low voltage for supplying the excitation windings of the traction motors.
При моторном режиме первична щетка S метадина подключена к сети, а щетка 9-к точке 75. При пуске двигателей М, /W,, Ж,, и УИ в начале приключаетс к сети метадин-возбудитель 5, по первичной цепи которого через щетки 8, 9 потечет ток /j, создающий магнитный поток 0i по оси щетки 8, 9.In motoring mode, the primary methadine brush S is connected to the network, and the brush 9 is located at point 75. When the M, / W ,, F ,, engines start up, at the beginning, the methadine-pathogen 5 comes to the network, through the primary circuit through brushes 8 , 9 current / j will flow, creating a magnetic flux 0i along the axis of the brush 8, 9.
Поток Фь в свою очередь, будет наводить Э.Д.С., а следовательно, и ток /2 во вторичной цепи, протекающий по щеткам б, 7 и по обмоткам возбуждени т говых двигателей.The flow Fj, in turn, will induce an electric current, and, consequently, a current / 2 in the secondary circuit flowing through brushes b, 7 and through the excitation windings of the traction motors.
Так как подведенное к щеткам 8,9 напр жение посто нно, то и ток 4 будет посто нным и максимальным по своей величине. В дальнейшем, при вращении двигателей (при увеличении оборотов) THj, /Из, Жз и М противоэлектродвижуща сила двигател УИ будет возрастать и уменьшать напр жение на щетках 8, 9 метадина-возбудител , а следовательно, будет уменьшать ток /, в обмотках возбужSince the voltage applied to the brushes 8.9 is constant, the current 4 will be constant and maximum in magnitude. In the future, when the engines rotate (as the engine speed increases) THj, / From, Zhz and M, the anti-propulsive force of the engine UI will increase and decrease the voltage on the brushes 8, 9 of the exciter methadine, and therefore will decrease the current /, in the windings will excite
