Description

Дл  регулировани  силы тормозного тока на электрических локомотивах при торможении посредством замыкани т говых электродвигателей на электрическое сопротивление, примен ютс  устройства , снабженные реле, включенным в I цепь тормозного тока и воздействующим тем или иным путем на возбуждение электродвигателей.To regulate the braking current on electric locomotives during braking by closing the traction motors to electrical resistance, devices equipped with a relay connected to the I braking current circuit and acting in one way or another on the excitation of the motors are used.

Предлагаемое изобретение касаетс  подобного устройства и состоит в особой форме его выполнени .The present invention relates to such a device and consists in a special form of its implementation.

На чертеже изображена схема устройства .The drawing shows a diagram of the device.

В цепь обмотки 75 возбуждени  т гового электродвигател  шунтируемого при торможении сопротивлением /5, включены источник тока 12 и реостат 77, подвижный контакт Ю которогр св зан черв чной передачей 8 с валом сервомотора 7. Сервомотор снабжен двум  чэбмотками возбуждени  2 н 3, включаемыми порознь, с целью сообщени   корю правого или левого хода посредством переключател  J6 и контактов 4 и 5. В цепь обмотки 2, предназначенной дл  сообщени   корю сервомотора 7 такого направлени  вращени , при котором ;опротивление реостата выводитс  из цепи возбуждени  электродвигател  М, включены контакты реле 6, упом нутого в начале описани . Реле 6 имеет двеIn the circuit of the excitation winding 75 of the traction motor shunt when braking with resistance / 5, a current source 12 and a rheostat 77 are included, the moving contact U is connected by a worm gear 8 with the servo motor shaft 7. The servomotor is equipped with two exciter chabmots 2 n 3 that are switched on, for the purpose of communicating the right or left stroke to the bore by means of the switch J6 and contacts 4 and 5. In the circuit of the winding 2, intended to bore the servo motor 7 of the direction of rotation in which; The motor is waiting, the contacts of the relay 6, mentioned at the beginning of the description, are switched on. Relay 6 has two

обмотки, из которых обмотка J9 присоединена к зажимам сопротивлени  75 в цепи электродвигател  f4, а обмотка 77 включена непосредственно в цепь его возбуждени .the windings, of which winding J9 is connected to the resistance terminals 75 in the motor circuit f4, and winding 77 is connected directly to its drive circuit.

Дл  торможени  т гового электродвигател  J4 переключатель J6 устанавливаетс  на контакт 4, вследствие чего сервомотор 7 включаетс  в цепь питани  7 и начинает врйщать через посредство черв чной передачи 8 подвижной контакт 70 реостата 77 вправо, постепенно вывод  сопротивление из цепи обмотки возбуждени  75. При этом сила тока в цепи возбуждени , а, равный образом, и в цепи электродвигател  /4, работающего в это врем  на сопротивление как генератор, будет соответственно возрастать.For braking the traction motor J4, the switch J6 is set to pin 4, as a result of which the servomotor 7 is included in the power supply circuit 7 and starts to vibrate through the worm gear 8 the moving contact 70 of the rheostat 77 to the right, gradually withdrawing the resistance from the excitation winding circuit 75. the current in the excitation circuit, a, in the same way, and in the motor circuit / 4, operating at this time on the resistance as a generator, will increase accordingly.

При превышении силы тормозного тока (или тормозного момента) некоторой определенной величины реле 6 приходит в действие и размыкает цепь обмотки 2 возбуждени  сервомотора. Этот пос-чедний останавливаетс  и прекращает дальнейшее выключение реостата 77, вследствие чего сила тока в обмотке возбуждени  75 и сила тока в тормозной цепи больше не измен етс , и торможение происходит норм ально.When the braking current (or braking torque) exceeds a certain value, relay 6 comes into action and opens the servo excitation winding circuit 2. This latter stops and stops further shutdown of the rheostat 77, as a result of which the current in the excitation winding 75 and the current in the brake circuit no longer change, and the braking occurs normally.
