Description
Измерение подшипниковых токов в электрической машине, у которой стул подшипника изолирован от станины, осуш;ествл ют с помош,ью электроизмерительного прибора, подключаемого одним зажимом к валу машины, а другим - к станине.Measurement of bearing currents in an electric machine, in which the bearing chair is isolated from the bed, is dried, with an electrical measuring instrument connected by one clamp to the shaft of the machine, and the other to the frame.
Предлагаемый способ более совершенен, так как он позвол ет повысить точность измерени подшипниковых токов в электрических машинах и дает возможность обнаруживать поврежденные участки изол ции. Повышенна точность измерени достигаетс тем, что между основной изол цией стула подшипника и наложенной на нее дополнительной изол цией (слой лака или лакоткань) помешают токопровод шую прокладку и подключают к ней второй зажим электроизмерительного прибора.The proposed method is more perfect, as it allows to increase the accuracy of measurement of bearing currents in electric machines and makes it possible to detect damaged areas of insulation. The increased measurement accuracy is achieved by the fact that between the main insulation of the bearing chair and the additional insulation laid on it (varnish layer or varnish-cloth) will prevent the conductor gasket and connect the second clamp of the electrical measuring device to it.
Дл обнаружени поврежденных участков изол ции, примен ют несколько отдельных токопровод щих прокладок, располагаемых в различных част х изол ции и поочередно подключаемых к электроизмерительному прибору при помощи переключател .To detect damaged areas of the insulation, several separate conductive gaskets are used, which are located in different parts of the insulation and are alternately connected to an electrical measuring device using a switch.
На фиг. 1 приведена схема измерени подшипниковых токов по предлагаемому способу; на фиг. 2 -схема, позвол юща обнаружить поврежденные участки изол ции.FIG. 1 shows a scheme for measuring the bearing currents of the proposed method; in fig. 2 is a circuit allowing detection of damaged areas of the insulation.
Между основной изол цией / стула подшипника и дополнительной изол цией 2 (слой лака или лакоткань) помещают токопровод щую прокладку 3. К ней подключак5т один из зажимов амперметра 4, друЮй зажим которого подключен к валу машины 5.A conductive gasket 3 is placed between the main insulation / bearing chair and additional insulation 2 (a layer of varnish or varnished cloth). One of the terminals of the ammeter 4 is connected to it, the other clip of which is connected to the shaft of the machine 5.
Дл обнаружени поврежденных участков изол ции примен ют не-сколько таких токопровод щих прокладок 3; их располагают в различных част х между изол ционными сло ми 1 -и 2 и поочередно подклю чаЮт к амперметру 4 при помощи переключател 6.To detect damaged areas of insulation, several such conductive gaskets 3 are used; They are located in different parts between the insulating layers 1 and 2 and alternately connect to the ammeter 4 by means of the switch 6.
