Description
Насто щее предложение представл ет собой устройство дл питани посто нным током нескольких синхронизированных асинхронных двигателей от одного возбудител . Устройство позвол ет с одной стороны применить возбудитель нормального напр жени (например, 220 вольт) при малых сопротивлени х обмоток роторов, последовательно включаемых в цепь посто нного тока. С другой стороны устройство позвол ет отключать обмотку ротора любого двигател без разрыва его цепи возбуждени This proposal is a device for direct current supplying several synchronized asynchronous motors from one exciter. The device allows, on the one hand, to apply a normal voltage exciter (e.g., 220 volts) with low resistances of the rotor windings connected in series in the DC circuit. On the other hand, the device allows to turn off the rotor winding of any engine without breaking its field circuit.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Обмотки 2, 2 роторов асинхронных двигателей питаютс от одного возбудител 8. Кажда из указанных обмоток при синхронизировании двигател присоедин етс параллельно сопротивлению 5, последовательно включенному с. другими подобными же сопротивлени ми 5 в цепь возбудител 8. Дл перевода двигател с асинхронного режима на синхронный служат двусторонние переклю-. чатели 4. Величины сопротивлени 5 и сопротивлений обмоток роторов не должны сильно отличатьс друг от друга во избежание сильных колебаний тока возбуждени при отключений отдельных двигателей. В этом случае, ток возбуждени благодар закорачиванию шунтовых сопротивлений возрастает. Дл умень- шени тока до требуемой величины служит реостат 9 в цепи возбуждени генератора . Дл сигнализировани о предельных отклонени х в обе стороны тока возбуждени служат реле тока 6 и 7, замыкающие сигнальную цепь JO.The windings 2, 2 of the rotors of the asynchronous motors are fed from one exciter 8. Each of these windings is connected in parallel with the resistance 5 connected in series with the synchronization of the engine. other similar resistances 5 to the driver circuit 8. To transfer the engine from asynchronous mode to synchronous mode, there are two-way switches. The values of the resistances 5 and the resistances of the rotor windings should not differ much from each other in order to avoid strong oscillations of the excitation current during disconnections of individual motors. In this case, the excitation current increases due to the shunting of the shunt resistances. To reduce the current to the required value, a rheostat 9 in the excitation circuit of the generator serves. For signaling the maximum deviations to both sides of the excitation current, current relays 6 and 7, which close the signal circuit JO, serve.
