Description

Предлагаетс  устройство дл  возбуждени  синхронной машины, снабжеиион отдельным возбудителем. В устройстве, с ucvibfp ioBbHueinm устойчивости параллельной работы машины при внезапном повьнпении тока нагрузки и защиты  кор  возбудител  от neperjrvsoK ударпым токами возбуждени , параллельно с  корем возбудите;г  нлн обмсггкой возбуждени  синхронной ман1ины включены последовательно соединенные конденсатор и вторична  обмотка трансформатора тока, первична  обмотка которого включена в цепь тока возбуждени .A device is proposed for driving a synchronous machine, providing a separate agent. In a device with ucvibfp ioBbHueinm stability of parallel operation of the machine in case of sudden povnpenii load current and protecting the armature pathogen from neperjrvsoK udarpym current excitation, in parallel with the armature rev; g nln obmsggkoy excitation synchronous man1iny includes series connected capacitor and the secondary of a current transformer whose primary is included into the excitation circuit.

На чертеже приведена принципиальна  электрическа  схема предлагаемого устройства.The drawing shows the principal electrical circuit of the proposed device.

Обмотка I возбуждени  синхронной маспипы 2 питаетс  от возбудител  3. Параллельно возбудителю прпкл Очен конденсатор 4, соединенный последоватслы о со вторичной обмоткой 5 трансформатора тока. Первична  обмотка 6 трансформатора включена последовательно в цень возбуждени  синхронной машины. Обмотка. 7 возбуждени  возбудител  3 включена как обычно через регулируемое сопротив.тение 8.The excitation winding I of the synchronous maspipa 2 is powered by the exciter 3. In parallel with the exciter exciter capacitor 4 is connected, connected with the secondary winding 5 of the current transformer. The primary winding 6 of the transformer is connected in series to the driving value of the synchronous machine. Winding. 7 excitation of the exciter 3 is switched on as usual through adjustable resistance. 8.

При стационарном режиме через цепь конденсатора 4 ток не протекает , вследствие чего возбуждение синхронной машины происходит обычным образом. При коротких замыкани х, а также (при других резких изменени х режима работы машины в обмотке возбуждени  1 индуктируюте  токи синхронной и нулевой частоты. Эти токи имерот больпше значени  и, замыка сь через  корь возбудител  3, ухудшают коммутацию , вызыва  искрение, а также в отдельных случа х перемагничивают или размагничивают возбудитель. Токи, индуктированные в обмотке возбуждени  1, особенно токи нулевой частоты, сами посебе не вредны. Наоборот, их действие в обмотке возбун дени  еинхронной машины еоздает полезный эффект, поддержива  устойчивость параллельной работы генератора. Поэтому в предлагаемом устройстве создан другой путь замыкани  этих токов-через конденсатор 4, помимо  кор  и другихIn stationary mode, no current flows through the capacitor circuit 4, as a result of which the synchronous machine is excited in the usual way. With short circuits and also (with other abrupt changes in the mode of operation of the machine, in the excitation winding 1 induce synchronous and zero frequency currents. These currents and measurements are of greater value and short-circuited through the measles of the exciter 3, impair switching, causing sparking, as well as individual cases of magnetization reversal or demagnetize the pathogen. The currents induced in the excitation winding 1, especially the currents of zero frequency, are not harmful in themselves. On the contrary, their action in the winding of the exciter of the induction machine has a beneficial effect resistance generator parallel operation. Therefore, the proposed apparatus set another path-circuit these currents through the condenser 4, in addition to the armature and other
