Description
Изобретение относитс к электроизмерительной технике и может быть использовано при определении качест - ва неэлектропроводных покрытий, преимущественно электрической изол ции на электропроводной основе.The invention relates to electrical measuring equipment and can be used in determining the quality of non-conductive coatings, mainly electrical insulation on an electrically conductive basis.
Целью изобретени вл етс повышение точности определени качества неэлектррпроводного покрыти , наход щегос на электропроводной основе. The aim of the invention is to improve the accuracy of determining the quality of a non-conductive coating based on an electrically conductive coating.
На чертеже представлена блок-схем варианта устройства дл реализации предлагаемого способа.The drawing shows a block diagram of a variant of the device for the implementation of the proposed method.
Устройство содержит источник 1 высокого напр жени , вольтметр 2, ка меру 3, электрод 4, электропроводную основу 5, неэлектропроводное покрытие 6, кольцевой емкостный датчик 7 тока ионов, усилитель 8 тока ионов индикатор 9 и вентил тор 10. The device contains a high voltage source 1, a voltmeter 2, a chamber 3, an electrode 4, an electrically conductive base 5, a non-conductive coating 6, an annular capacitive ion current sensor 7, an ion current amplifier 8 indicator 9, and a fan 10.
Устройство работает следующим образоМоThe device works as follows
Под действием пол источника 1 высокого напр жени , приложенного между электропроводной основой 5 и элekтpoдoм 4, происходит выход электронов через дефекты неэлектропроводного покрыти 6.Under the action of the floor of the high voltage source 1, applied between the conductive base 5 and the electrode 4, electrons escape through the defects of the non-conductive coating 6.
Эти электроны, проника в среду газа, заполн ющего камеру 3, вызывают ионизацию газа, например, водорода . Чем больше дефектов в неэлектропроводном покрытии, тем больше образовываетс ионов. Под действием вентил тора 10 ионы газа достигают кольцевого емкостного датчика 7 тока ионов, к электродам которого подведено низкое напр жение и измер ютс им.These electrons, penetrating the gas medium filling chamber 3, cause the ionization of a gas, for example, hydrogen. The more defects in a non-conductive coating, the more ions are formed. Under the action of the fan 10, the gas ions reach the annular capacitive sensor 7 of the ion current, to whose electrodes a low voltage is applied and measured.
Ток ионов газа, выделенный кольцевым емкостным датчиком 7 тока ионов , усиливаетс усилителем 8 тока ионов и отображаетс индикатором 9. Вольтметр 2 позвол ет измер ть напр жени источника 1 высокого напр жени .The gas ion current detected by the annular capacitive ion current sensor 7 is amplified by the ion current amplifier 8 and displayed by the indicator 9. The voltmeter 2 allows the voltage of the high voltage source 1 to be measured.
Использование предлагаемого способа определени качества неэлектропроводных покрытий на электропроводной основе позвол ет повысить точность определени качества неэлектропроводных покрытий, так как используетс количественна величина ток ионов газа, непосредственно св занна с наличием дефектов в неэлектропроводном покрытии; производить исследование старени неэлектропроводных покрытий, работающих в среде какого-либо газа, а также непрерывный контроль сопротивлени изол ции электрических машин с водородным охлаждением, например турбогенераторов , в процессе их работы.The use of the proposed method of determining the quality of non-conductive coatings on an electrically conductive basis improves the accuracy of determining the quality of non-conductive coatings, since a quantitative value of the current of gas ions directly related to the presence of defects in the non-conductive coating is used; to carry out a study on the aging of non-conductive coatings operating in the medium of any gas, as well as continuous monitoring of the insulation resistance of hydrogen-cooled electric machines, such as turbo-generators, during their operation.
