Description
(54) УСТРОЙСТВО ТРЕХФАЗНОГО(54) THREE-PHASE DEVICE
ДЛЯ РЕГУЛИРОВАНИЯ НАПРЯЖЕНИЯFOR REGULATING VOLTAGE
ровани , включаетс тиристор 11. При вкпчении тиристора 11 тиристор 12 запираетс обратным напр жением с отводом 9 и 10. Попожитепьна попувопна выходного напр жени устройства имеет ступенчато-синусои дапьную форму. Отрицатегаьна полуволна напр жени на первичной обмотке сначала состоит из напр жени сети, прошедшего через открытый еще за счет зат жки тока тиристор 11 (участок 13 на фиг. 3a)ja затем из напр жени , наведенного магнитными потоками, созданными обмотками других стержней и проход щими через данный стержень (участок 14 на фиг. За). За.т жка тока тиристора 11 вызвана индуктив-The thyristor 11 is turned on. When thyristor 11 is inserted, thyristor 12 is locked by reverse voltage with a tap of 9 and 10. Stand on the output voltage of the device has a step-sine shape. The negative half-wave voltage on the primary winding first consists of the network voltage passing through the thyristor 11 still open due to current tightening (section 13 in Fig. 3a) ja then from the voltage induced by the magnetic fluxes created by the windings of the other rods and passing through this rod (section 14 in Fig. For). For the current thyristor 11 is caused by inductive

Несмотр на то, что ток в первичных обмотках трансформатора однопол рный, в каждом стержне сердечника трансформатора положительна и отрицательна полуволны потока приблизительно равны и его сердечник не насьпцаетс .Despite the fact that the current in the primary windings of the transformer is unipolar, in each core of the transformer core the positive and negative half-waves of the current are approximately equal and its core is not pressed.
Работа устройства возможна только при наличии трехстержневого сердечника.The operation of the device is possible only with a three-core core.
В предлагаемом устройстве исключеноIn the proposed device is excluded
короткое замыкание регулировочных отводов через тиристоры даже при неправильной подаче импульсов управлени на тирис-, торы, что существенно снижает требовани к схеме управлени , особенно при реактивной нагрузке.short-circuiting of the adjusting taps through the thyristors even if the control pulses are not correctly applied to the thyristors and tori, which significantly reduces the requirements for the control circuit, especially under reactive load.
Количество регулировочных отводов и тиристоров, присоединенных к ним, в устройстве в привдипе не ограничено.The number of adjusting taps and thyristors attached to them in the device in gear is not limited.
