Определение диапазона номинальной мощности электродвигателей при испытаниях методом динамического нагружения

Определение диапазона номинальной мощности электродвигателей при испытаниях методом динамического нагружения

Abstract

Данная статья направлена на решения проблемы испытания электрических машин после ремонта. При помощи рассматриваемого метода предполагается нагрузить асинхронный двигатель тормозным электромеханическим моментом без использования механической нагрузки на валу. Автором представлены результаты по нагружению электродвигателя данным способом, полученные при моделировании системы в программе Matlab. После получения положительных результатов при испытаниях электродвигателя небольшой мощности были проведены эксперименты на асинхронных электродвигателях серии 4А. Проведенные эксперименты позволяют сделать вывод о получении эквивалентной механической мощности на валу электродвигателя порядка 25-30% от номинальной, о возможности испытания под нагрузкой без применения нагрузочных устройств данным способом только электродвигателей небольшой мощности. Также в статье даются рекомендации по испытаниям электрических машин мощностью более 3 кВт с применением делителей частоты. Кроме того, данный метод позволяет сохранить часть запасенной энергии, но применение обратимых полупроводниковых преобразователей может быть неоправданным. После реализации способ позволит создать стенды для испытания электрических машин нового поколения.

This article is directed on solutions of the problem of test of electric machines after repair. By means of a considered method it is supposed to load the asynchronous engine with the brake electromechanical moment without use of mechanical loading on a shaft. The author presented results on electric motor loading by this way, the systems received at modeling in the Matlab. After receiving positive results at tests of the electric motor of small power, experiments on asynchronous electric motors of a series 4A were made. The made experiments allow to draw a conclusion on obtaining equivalent mechanical power on an electric motor shaft about 25-30% from nominal, on possibility of test under loading without use of load devices by this way only electric motors of small power. Also in article recommendations about tests of electric cars with power more than 3 kW with application of dividers of frequency are made. Besides, this method allows to keep part of the reserved energy, but use of reversible semiconductor converters can be unjustified. After realization the way will allow to create stands for test of electric machines of new generation.
