Description
(54) УСТЮЙСГВО ДЛЯ ПУСКА АСИНХРОННОГО КОРОТКОЗАМКНУТОГО ЭЛЕКТРОДВИГАТЕЛЯ(54) ACCESS FOR STARTING ASYNCHRONOUS SHORT CAMERA ELECTRIC MOTOR
Такое решение обеспечивает высокую стабилизацию напр жени , так как емкостной ток нагрузки генератора способствует повышению напр жени , чем компенсируетс падение напр жени на сопротивлении Хс.This solution provides a high voltage stabilization, since the capacitive load current of the generator contributes to an increase in voltage, which compensates for the voltage drop across the resistance Xc.
На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит синхронный генератор 1, последовательно в цепь с которым включены реле 2 реактивной мощности, ступени статических конденсаторов 3 и асинхронньш двигатель 4. Параллельно ступен м конденсаторов включено переключающее устройство 5. Переключающее устройство 5 подключено к выходу реле 2 реактивной мощности.The device contains a synchronous generator 1, sequentially in the circuit with which the relay 2 of reactive power is connected, the stages of static capacitors 3 and the asynchronous motor 4. Parallel to the stages of the capacitors switching device 5 is switched. Switching device 5 is connected to the output of relay 2 of reactive power.
В момент включени асинхронного двигател все ступени 1$)нденсаторов 3 включены в цепь двигател , по мере -его разгона и уменьшени индуктивной составл ющей мощности, когда в цепи начи нает преобладать емкостна составл юща мощности , сраб тьшает реле 2 реактивной мощности и вьщает сигнал в переключающее устройство 5, которое saMbtKaeT одну из ступеней конденсаторов 3. Постепенно в процессе пуска замыкаютс все ступени конденсаторов. Реле реактивной мощности отстраиваетс на срабатьша1ше при величинеAt the moment the induction motor is turned on, all stages 1 $) of the capacitors 3 are included in the motor circuit, as it accelerates and decreases the inductive component of power, when the capacitive component of the circuit begins to dominate, clears the relay 2 of reactive power and increases the signal switching device 5, which saMbtKaeT is one of the stages of the capacitors 3. Gradually, in the process of starting, all the stages of the capacitors are closed. The reactive power relay is tuned to the operating system when the
емкостной мощности пор дка 1-3% от полной мощности генератора. Переключающее устройство может быть выполнено как на релейно-контактных , так и полупроводниковых элементах.capacitive power is in the order of 1-3% of the total generator power. The switching device can be made on the relay-contact and semiconductor elements.
Предлагаемое устройство позвол ет обеспечить более высокую степень стабилизации напр жени в момент запуска двигател , так как в процессе пуска осуществл етс непосредственный контроль реактивной мощности, что позвол ет отключать ступени конденсаторов в тот момент, когда в цепи преобладает емкостна мощность.The proposed device allows for a higher degree of voltage stabilization at the time of engine start, since during the start-up process, reactive power is directly controlled, which allows disconnecting the capacitor stages at the moment when capacitive power prevails in the circuit.
