Description

Предметом изобретени   вл етс  устройство дл  автоматического управлени  т говыми двигател ми посто нного тока посредством индивидуальных электромагнитных контакторов и реле ускорени .The subject of the invention is a device for the automatic control of a direct current traction motor by means of individual electromagnetic contactors and an acceleration relay.

Недостатком схем, примен емых дл  автоматического пуска т говых двигателей посто нного тока, при индивидуальных контакторах  вл етс  многочисленность блок-контактов .The drawback of the circuits used for automatic start-up of direct current motors with individual contactors is the large number of auxiliary contacts.

В предлагаемом устройстве этот недостаток устранен включением последовательно с катушками контакторов , добавочных сопротивлений , обеспечивающих самоудержание контакторов, и блок-контактов меж,зу цепью питани  первого (по пор дку действи ) контактора и цеп ми остальных контакторов. Действие такой схемы основано на использовании низкого коэфициента возврата электромагнитных контакторов .In the proposed device, this disadvantage is eliminated by the inclusion in series with the coils of the contactors, the additional resistances ensuring the self-retention of the contactors, and the block contacts between, the power supply circuit of the first contactor (in order of operation) and the circuits of the other contactors. The operation of such a scheme is based on the use of a low return coefficient of electromagnetic contactors.

Якорь контактара / прит гиваетс , когда реле ускорени  вследствие спадани  тока в цепи двигателей отпадет и замкнет свои контакты РУ, шунтиру  тем самым сопротивление TI. При включении контактора / ток в цепи двигателей увеличитс , что вызовет прит жение  кор  РУ и размыкание его контактов. Вследствие этого контактор 2, катушка которого присоедин етс  через блокконтакты / параллельно катушке 1, не успевает включитьс . Включение контактора 2 произойдет при повторном отпадании реле ускорени  и замыкании его контактов, что будет иметь место в результате уменьшени  тока двигателей при разгоне.The anchor of the contactee / is attracted when the acceleration relay, due to the decay of the current in the motor circuit, falls off and closes its switchgear contacts, thereby shunting the resistance TI. When the contactor is turned on, the current in the motor circuit will increase, which will cause attraction of the switchgear and opening of its contacts. As a consequence, the contactor 2, the coil of which is connected through the blocking contacts / parallel to the coil 1, does not have time to turn on. The contactor 2 is turned on when the acceleration relay reappears and its contacts close, which will occur as a result of a decrease in the motor current during acceleration.

В дальнейшем вышеописанный процесс повтор етс  дл  2-го,3-го и последующих контакторов.Further, the above process is repeated for the 2nd, 3rd and subsequent contactors.
