Description
Дл получени посто нного тока с мало измен ющимс напр жением при переменном числе оборотов примен ютс обычно машины Розенберга, . которые имеют склонность искрообразовани у поперечных щеток. Предлагаемое устройство дл получени посто ннного тока с посто нным напр жением при переменном числе оборотов имеет целью устранение вышеупом нутого недостатка.To obtain direct current with a slightly varying voltage at varying speeds, Rosenberg machines are usually used. which have a tendency to sparking a transverse brush. The proposed device for obtaining a constant current with a constant voltage at a variable speed is aimed at eliminating the aforementioned drawback.
На чертеже фиг. 1 изображает схему предлагаемого устройства; фиг. 2 и 3 - видоизменениеее.In FIG. 1 depicts the scheme of the proposed device; FIG. 2 and 3 - modifications.
Предлагаемое устройство дл получени посто нного тока с посто нным напр жением при переменном числе оборотов электрическаго генератора состоит из насаженного на вал генератора А вспомогательной машины В, корь которой включен последовательно с обмоткой возбуждени С генератора, а обмотка возбуждени D которой либо присоединена .параллельно к ее корю (фиг. 1), либо включена последовательно с ним (фиг. 2), либо включeнa параллельно цепи возбуждени генератора (фиг. 3).The proposed device for producing direct current with constant voltage at a variable speed of an electric generator consists of an auxiliary machine B mounted on an alternator A shaft, the measles of which are connected in series with the exciter winding C of the generator, and the excitation winding D of which is either connected in parallel to it Koryu (Fig. 1), either connected in series with it (Fig. 2), or connected in parallel with the generator excitation circuit (Fig. 3).
Действие предлагаемого устройства состоит в следующем. При увеличении числа оборотов генератора увеличиваетс The action of the proposed device is as follows. Increasing the number of revolutions of the generator increases
также число оборотов вспомогательной машины, работающей как двигатель, вследствие чего возрастает ее противоэлектродвижуща сила, действующа навстречу приложенному напр жению генератора . Напр жение, приход щеес на обмотки возбуждени генератора, а следовательно , и поток уменьшаютс . При этом важно, чтобы возрастание противоэлектродвижущей силы двигател от увеличени числа оборотов происходило быстрее, нежели возрастание напр жени генератора, что достигаетс соответству. ющим расчетом генератора и двигател Предмет изобретени .also, the number of revolutions of the auxiliary machine operating as an engine, as a result of which its counter electromotive force increases, acting against the applied voltage of the generator. The voltage coming to the generator windings of the generator, and consequently the flow, is reduced. It is important that the increase in the counter-electromotive force of the engine from an increase in the number of revolutions occurs faster than the increase in generator voltage, which is achieved accordingly. The calculation of the generator and engine The subject invention.
1. Устройство дл получени посто нного тока с посто нным напр жением при переменном числе оборотов, электрического генератора, отличающеес применением насаженной на вал генератора вспомогательной машины, предназначенной давать электродвижущую силу, обратную напр жению генератора, корь каковой машины включен с обмоткой возбуждени генератора и обмотка возбуждени которой присоединена параллельно к корю ее (фиг. 1).1. An apparatus for producing direct current with constant voltage at a variable speed, an electric generator, characterized by the use of an auxiliary machine mounted on the generator shaft, intended to give an electromotive force that is inverse to the voltage of the generator, which machine is connected to the generator winding and winding the excitation of which is connected in parallel to its core (Fig. 1).
