Description

Оп)еделенце индуктивных сопротивлений асиихрониой двухфазной ,1ашины с полым ротором ироизводитс  в большинстве случаев путем вычислений на основаини результатов опыта холостого хода.(I) The inductive impedance element of the two-phase asychrony, a hollow-rotor machine, is produced in most cases by calculating the results of the no-load test based on the results of the idle cycle.

Предлагаемый способ более совертиенен, так как он позвол ет существенно упростить определение индуктивных сопротивлений.The proposed method is more sophisticated, since it makes it possible to significantly simplify the determination of inductive resistances.

Это достигаетс  тем, что при испытани х одну из статорпых обмоток машины присоедин ют к питающей сети, вторую замыкают на вольтметр и производ т измереии  при двух опытах. При первом опыте ротор раскручивают посторонним двигате.гем до скорости не ниже 0,4 синхронной, а при втором опыте до скорости, лежащей у верхней границы диапазона рабочих скоростей машины.This is achieved by testing one of the stator windings of the machine connected to the mains, the second is closed by a voltmeter and measured in two experiments. In the first experiment, the rotor is unwound with an extraneous engine. The speed of the motor is not lower than 0.4 synchronous, and with the second experiment, the speed lies at the upper limit of the working speed range of the machine.

Па фиг. 1 и 2 изображены схемы измерени  индуктивных сопротивлений асинхронной двухфазной машины по предлагаемому способу.Pa figs. Figures 1 and 2 depict a circuit for measuring inductive resistances of an asynchronous two-phase machine according to the proposed method.

Ротор / испытуемой асинхронной машины механически соедии етс  с регулируемым приводным двигателем 2 и измеретелем скоростн вращени  3. Параметры испытываемой .машины определ ютс  на основе двух опытов: опыта холостого хода, при котором одна из об моток 4 машины подключена к сети пе)еменного тока, втора  обмотка 5 включена на вольтметр 6 (фиг. 1),а ротор врашаетс  ео скоростью не ниже 40% от синхронной, и такого же опыта, но при скоростн вращени  ротора, лежаохей у верхней границы дианазона рабочих скоростей машины.The rotor / asynchronous machine under test is mechanically connected with the adjustable drive motor 2 and the rotational speed meter 3. The parameters of the test machine are determined on the basis of two experiments: an idling experience in which one of the windings 4 of the machine is connected to a network of continuous current, The second winding 5 is connected to a voltmeter 6 (Fig. 1), and the rotor rises at a speed not lower than 40% of the synchronous, and the same experience, but at the speed of rotation of the rotor, lying at the upper boundary of the machine's working speed.

Ползченные при проведении этих опытов результаты измерени  тока в обмотке 4, присоединенной к сети, и нанр жени  иа обмотке 5, замкнутой на вольтметр, позвол ют вычнстить искомые реактивные сопротивлени .The results of current measurements in a winding 4 connected to the network and in a winding 5 closed to a voltmeter, crawled during these experiments, make it possible to find the required reactances.

С целью контрол  полученных результатов нронзводитс  трети опыт, при котород-г обмотка 4 за.мыкаетс  иа вольтметр, а обмотка 5 присоедин етс  к питающей сети (фиг. 2). Ротор раскручиваетс  при этом до скорости, лежащей в диапазоне ))абочих скоростей машины.In order to control the obtained results, one-third of the experience is established, in which the coil 4 is closed by a voltmeter and the coil 5 is connected to the mains (Fig. 2). The rotor is unwound with this up to a speed lying in the range)) of the working speeds of the machine.
