Description

Насто щее изобретение относитс  к сиособам управлени  т говыми двигател ми шестиосного электровоза посто ииого тока, основанным на использовании мостовой схемы дл  перехода двигателей с одного соединени  на другое и осуществл емым с помощью пусковых сопротивлений , подразделенных на четыре группы.The present invention relates to motor control methods for traction motors of a six-axle electric locomotive of direct current, based on the use of a bridge circuit for switching motors from one connection to another and carried out using starting resistances, divided into four groups.

Предлагаемый способ отличаетс  от известных тем, что на последовательно-параллельном « параллельном соединени х указанные группы сопротивлений св зывают при помощи уравнительных соединений по две Б параллель и одну из этих пар групп включают со стороны токоприемника , а другую - со стороны земли.The proposed method differs from the known ones in that, in series-parallel connections, the said resistance groups are connected by equalizing connections, two B each, and one of these pairs of groups is connected on the current collector side, and the other on the ground side.

Такой способ позвол ет улучшить использование пусковых сопротивлений .Such a method makes it possible to improve the use of starting resistances.

На фиг. 1 изображена схема электровоза, т говые двигатели которого управл ютс  по предлагаемому способу; на фпг. 2 - таблица замыкани  его контакторов.FIG. 1 shows a diagram of an electric locomotive, the traction engines of which are controlled by the proposed method; on phpg. 2 - the closure table of its contactors.

На схеме (фиг. 1) показана только коммутирующа  в нроцессе переходов аппаратура. Реостатные контакторы в каждой группе пусковых сопротивлений представлены условно одним контактором. Пусковые сопротивлени  R подразделены на четыре группы. В процессе пуска на последовательно-параллельном и параллельном соединени х они св зываютс  уравнительными соединени ми по две в параллель и одну из этих групп включают между токоприемником и двигател ми Mi - Да, а другую - между двигател ми Mi - Дв и землей. Така  схема пуска обеспечивает хорошее использование нусковых сопротивлений и реостатных контакторов на всех соединени х т говых двигате тей. Несмотр  на некоторое увеличение числа контакторов, зчаствующих в перегруппировках двигателей, общее их количество в предлагаемой схеме (24) значительно меньще по сравнению с другими известными схемами. Надо также отметить, что шесть контакторов, участвующих в нроцессе пе1рехода (№№ 2, 4, 5, 15, 17, 19),  вл ютс  по существу «екоммутирующими.The diagram (Fig. 1) shows only the equipment commuting in the transition process. Rheostatic contactors in each group of starting resistances are represented conventionally by one contactor. The starting resistances R are divided into four groups. In the process of starting on series-parallel and parallel connections, they are connected by equalizing connections two by two in parallel and one of these groups is connected between the current collector and the engines Mi - Yes, and the other between the engines Mi - Dv and the ground. This start-up circuit ensures good use of the starting resistors and rheostatic contactors on all connections of the traction motors. In spite of a slight increase in the number of contactors that play in the rearrangements of engines, their total number in the proposed scheme (24) is significantly smaller compared to other known schemes. It should also be noted that the six contactors involved in the transition process (Nos. 2, 4, 5, 15, 17, 19) are essentially "commuting."
