Description
Насто щее изобретение относитс к способам определени индуктивных сопротивлений, асинхронной двухфазной машины с полым р.отором путем вычислени их «а осноБ.ачии результатов опытов, проводимых с использованием постороннего двигател дл раскручивани ротора исследуемой машины.The present invention relates to methods for determining inductive impedances, an asynchronous two-phase machine with a hollow rotor by calculating them on the basis of the results of experiments carried out using an external motor to spin the rotor of the machine under investigation.
Предлагаемый способ отличаетс от известных тем, что при исследовании провод тс два опыта. При первом опыте одну из статорных обмоток оставл ют разомкнутой, а другую присоедии ют к сети последовательно с переменной емкостью, раскручивают ротор до синхронной скорости, регулируют указаннук емкость до получени резонанса напр жений и производ т за;мер напр жени сети и тока в подключенной к сети обмотке статора. При втором опыте от присоединенной к сети обмотки отключают переменную емкость, подключают ее к другой обмотке статора, раскручивают ротор до синхронной скорости , регулируют емкость до получени резонанса напр жений и производ т замер токов в обеих обмотках статора.The proposed method differs from the known ones in that two experiments are carried out in the study. In the first experiment, one of the stator windings is left open, and the other is connected to the network in series with variable capacitance, the rotor is turned up to synchronous speed, the indicated capacitance is adjusted to obtain voltage resonance and the network voltage and current connected to network winding stator. In the second test, the variable capacitance is disconnected from the connected winding, connected to another stator winding, the rotor is turned up to a synchronous speed, the capacitance is adjusted before the voltage resonance and the currents in both stator windings are measured.
Применение такого способа позвол ет упростить процесс определени -индуктивных сопротивлений.The use of such a method simplifies the process of determining -inductive resistances.
На фиг. 1 и 2 изображена схема включени исследуемой аоинхронной машины при определении индуктивных сопротивлений ее обмоток по предлагаем01му способу.FIG. Figures 1 and 2 depict the switching circuit of the investigated in-line machine when determining the inductive resistances of its windings according to the proposed method.
Определение индуктивных сопротивлений двухфазной- маш-ины осуществл етс на основа-НИИ результатов двух опытов, при которых создаетс резонанс напр жений.The determination of inductive resistances of a two-phase machine is carried out on the basis of a research institute of the results of two experiments in which a voltage resonance is created.
При -первом опыте фазова обмотка А статора подК.г Ючаетс к посто нно-му по величине -напр жению НА . а ротор Р машины рас«ручиваетс внешним двигателем D до синхронной скорости. Втора фазова обмотка В статора ма-ши-ны прИ этом размыкаетс . Измен величину емкости С А, включенной последовательно с обмоткой А, добиваютс резонанса напр лсени , который -обнаруживаетс с помощью фазометра или по максимальному отклонению амперметра в простейшем случае.In the first experiment, the phase winding A of the stator CK yuchatsa to constant in magnitude, the voltage ON. The rotor P of the machine is driven by an external motor D to a synchronous speed. The second phase winding in the stator of the engine is disconnected. By varying the capacitance C A connected in series with the winding A, a resonance of voltage is reached, which is detected by a phase meter or by the maximum deviation of the ammeter in the simplest case.
