Description
Уже известно применение дл регулировани электрических машрн электрических вентилей, включаемых параллельно обмотке возбуждени машины. В предлагаемом же устройстве, кроме включенного указанным способом электрического вентил , применена еще и соединенна последовательно с ним вспомогательна батаре . При повышении числа оборотов машины и уменьшении вследствие этого напр жени на зажимах обмотки возбуждени через нее проходит дополнительный ток от батареи. При нормальной же работе, когда напр жение на зажимах этой обмотки больше, чем напр жение батареи, joS: не может проходить через последнюю вследствие дейс; тви вентил .The use for regulating electrical machines of electric valves connected in parallel with the excitation winding of a machine is already known. In the proposed device, besides the electric valve switched on by the above method, an auxiliary battery connected in series with it is also used. As the number of revolutions of the machine increases and, as a result, the voltage decreases at the terminals of the field winding, additional current from the battery passes through it. During normal operation, when the voltage at the terminals of this winding is greater than the battery voltage, joS: cannot pass through the latter due to the action; Twi Vent.
На чертеже изображена схема включени устройства.The drawing shows a diagram of the inclusion of the device.
Параллельно обмотке возбуждени 7 сериесного двигател включен источник тока 2, например, батаре , электрический вентиль 3 и регулировочное сопротивление 4, соединенные между собой последовательно. Часть сопротивлени шунтирована сигналь ным приспособлением , например электрическим звойком. При нормальной работе мотора напр жение на зажимах обмотки возбуждени Parallel to the excitation winding 7 of the serial motor, a current source 2 is switched on, for example, a battery, an electric valve 3 and an adjusting resistance 4 connected in series with each other. Part of the resistance is shunted by a signal device, such as an electric bell. During normal operation of the motor, the voltage on the terminals of the excitation winding
больше, чем напр жение батареи, но зар дный ток не может проходить через нее вследствие наличи вентил .is greater than the battery voltage, but the charging current cannot pass through it due to the presence of a valve.
При повышении числа оборотов напр жение на зажимах обмотки 1 уменьшитс и батаре начнет разр жатьс через двигатель, что вызовет увеличение противоэлектродвижущей силы и уменьшение оборотов. Одновременно электрический сигнал привлечет внимание обслуживающего персонала.As the number of revolutions increases, the voltage at the terminals of winding 1 will decrease and the battery will begin to discharge through the engine, which will cause an increase in the counter electromotive force and a decrease in revolutions. At the same time, an electrical signal will attract the attention of service personnel.
Предмет изобретени .The subject matter of the invention.
Устройство дл ограничени оборотов сериесного двигател при сбрасывании нагрузки с применением электрического вентил , отличающеес тем, что указанный вентиль, например, сухой выпр митель , и соединенна последовательно с ним вспомогательна батаре включены параллельно обмотке возбуждени с тем, чтобы при повышении числа оборотов и уменьшении напр жени на зажимах указанной обмотки через нее протекал дополнительный ток от батареи, в то врем как при нормальной работе и при напр жении на зажимах обмотки воз-буждени , большем, чем напр жение батареи , прохождение зар дного тока через нее предотвращалось-наличием вентил A device for limiting revolutions of a serial engine when a load is shedding using an electric valve, characterized in that said valve, for example, a dry rectifier, and an auxiliary battery connected in series with it are connected in parallel to the excitation winding so that at the terminals of the indicated winding an additional current from the battery flowed through it, while during normal operation and when the voltage on the terminals of the winding of the excitation is greater than April battery voltage, the charging current passing therethrough is prevented by the presence of the fan-
