Description

Устройство по основному авт. св. А 123604 содержит схему моделировани  процессов, происход щих в асинхронном двигателе при помощи двух спериалБных трансформаторов, с последующим измерением токов и напр жений выходных обмоток этпх трансформаторов.The device according to the main author. St. A 123604 contains a scheme for modeling processes occurring in an asynchronous motor using two sperial transformers, followed by measuring the currents and voltages of the output windings of these transformers.

Особенность (предложенного устройства заключаетс  в том, что дл  использовани  схемы при измерении вращающего момента на валу асинхронного двигател  применен Еаттметровьи . электрический измерительный прибор, обмотки тока и напр жени  которого подключены через выпр мители ко вторичньш обмоткам трансформаторов тока основного устройства.The peculiarity (of the proposed device is that for using the circuit to measure the torque on the shaft of the induction motor, an electric measuring device is used, the current windings and voltage of which are connected through the rectifiers to the secondary windings of the current transformers of the main device.

На чертеже изображена принципиальна  схема предложенного устройства.The drawing shows a schematic diagram of the proposed device.

Принцип действи  и эквивалентна  схема замещени  асинхронного двигател  приведены в ооновн ом авторском свидетельстве.The principle of operation and the equivalent replacement circuit for an asynchronous motor are given in the United States copyright certificate.

Испытываемый двигатель / подключен к трехфазной сети переменного тока.Test motor / connected to a three-phase AC network.

Схема состоит из двух трансформаторов 2 и 3. Трансформатор 2 имеет четыре обмотки три токовые и одну вторичную. По двум токовым обмоткам протекают фазные токи нагрузки. Эти обмотки включены встречно и их действие эквивалентно действию одной обмотки, обтекаемой линейным током. Треть  токова  обмотка обтекаетс  током величина которого осуществл етс  параметрами дроссел  4, включенного в эту цепь.The circuit consists of two transformers 2 and 3. Transformer 2 has four windings, three current and one secondary. Two current windings flow phase load currents. These windings are included counter and their action is equivalent to the action of a single winding flowed around a linear current. The third current winding is encircled by a current whose value is realized by the parameters of the throttles 4 included in this circuit.

Цепь этой обмотки подключаетс  на линейное напр жение и параметры ее выбираютс  таким образом, чтобы сопротивлени  трансформаторов 2 к 3, приведенные к этой пепи, были много меньше активного и реактивного сопротивлений, включенных и их цепь. Треть  токова  обмотка чoдключaeтc  таким образом, чтобы в цепи вторичной обмоткиThe circuit of this winding is connected to a linear voltage and its parameters are chosen in such a way that the resistances of the 2 to 3 transformers brought to this peep are much less than the active and reactive resistances included and their circuit. A third of the current winding is connected in such a way that the secondary winding
