Исследование работы электротехнического комплекса с емкостным преобразователем

Abstract

Рассмотрен электротехнический комплекс с емкостным электромеханическим преобразователем энергии (ЕЭМПЭ), подвижным элементом которого является диэлектрическая жидкость. Определено взаимовлияние параметров электрического поля, создаваемого в емкостном преобразователе, и свойств жидкости, проявляющихся в возникновении в ней направленного движения. С использованием электромеханических и электрогидродинамических аналогий были получены уравнения электромеханического преобразования при различных видах приложенного напряжения: постоянного, переменного однофазного и трехфазного. Получена формула для определения коэффициента полезного действия преобразователя. Численно найдены и экспериментально подтверждены оптимальные параметры преобразователя для возникновения направленного движения в жидкости с заданной скоростью. При этом учитывались такие свойства жидкости, как вязкость, электропроводность и поляризация.

The electro technical complex with capacitive electromechanical energy transducer (CEET) having a dielectric liquid as moving element, is considered. The mutual influence of electrical field parameters, created in the capacitive transducer, and liquid properties, which are shown in occurrence of directed movement into liquid, are determined. The equations of electromechanical transformation were received at various kinds of the applied voltage: direct, variable single-phase and three-phase, at using of electromechanical and electrohydrodynamical analogies. The formula for definition of efficiency of the transducer is received. The optimum parameters of the transducer for occurrence of the directed movement in a liquid with the given speed are numerically found and experimentally confirmed. Thus such properties of a liquid, as viscosity, electro leakage and polarization were taken into account.
