Abstract
Изобретение относитс к электротехнике и может быть использовано дл контрол качества пропитки и степени увлажнени обмоток электрических машин. Целью изобретени вл етс повышение достоверности контрол качества пропитки и степени увлажнени электрических машин. Устройство дл контрол качества изол ции электрической машины 1 содержит источник 2 переменного тока, один из выводов которого заземлен, а другой вывод через симметрирующий конденсатор 3 и первичные обмотки трансформаторов 4 и 5 тока, включенные последовательно-согласно, присоединен к исследуемой электрической машине 1. Параллельно источнику 2, конденсатору 3 и первичной обмотке трансформатора 4 тока подключен через диод 6 переменный резистор 7. Вторичные обмотки трансформаторов 4 и 5 тока через переключатель 8 режима измерени подключены к измерительному прибору 9, один из выводов переключател 8 соединен со средней точкой соединени вторичных обмоток, причем последние шунтированы резисторами 10 и 11. Введение двух резисторов, переключател режима, двух трансформаторов тока позвол ет повысить достоверность контрол качества пропитки и сушки изол ции электрических машин. 1 ил.The invention relates to electrical engineering and can be used to control the quality of impregnation and the degree of wetting of the windings of electrical machines. The aim of the invention is to increase the reliability of the quality control of the impregnation and the degree of wetting of electric machines. A device for monitoring the quality of the insulation of an electric machine 1 contains an AC source 2, one of the terminals of which is grounded, and the other terminal through a balancing capacitor 3 and the primary windings of current transformers 4 and 5, connected in series, are connected to the electrical machine 1 under study. the source 2, the capacitor 3 and the primary winding of the current transformer 4 is connected via a diode 6 variable resistor 7. The secondary windings of the current transformers 4 and 5 are connected to the measuring mode switch 8 The measuring device 9, one of the pins of the switch 8 is connected to the midpoint of connection of the secondary windings, the latter being bridged by resistors 10 and 11. The introduction of two resistors, a mode switch, two current transformers allows to increase the reliability of quality control of impregnation and drying of electrical machines insulation. 1 il.
