СПОСОБ РЕГИСТРАЦИИ ВНУТРЕННИХ ЧАСТИЧНЫХ РЯЗРЯДОВMETHOD OF REGISTRATION OF INTERNAL PARTIAL RYAZRIES

И КОРОНЫ В ДИЭЛЕКТРИКАХ ПРИ ПОСТОЯННОМ НАПРЯЖЕНИИ И УСТРОЙСТВО ДЛЯ ОСУЩЕСТВЛЕНИЯAND CROWNS IN DIELECTRICS UNDER CONSTANT VOLTAGE AND DEVICE FOR IMPLEMENTATION

За влено 20 окт бр  1958 г. за № 609954/24 в Комитет по делам изобретений и открытий при Совете Министров СССРIt was filed on October 20, 1958 under No. 609954/24 in the Committee for Inventions and Discoveries under the Council of Ministers of the USSR

Опубликовано в «Бюллетене изобретении ЛГ 10 за 1959 г.Published in the Bulletin of the invention of LG 10 for 1959.

Предлагаетс  способ регистрации внутренних частичных разр дов и короны в диэлектриках при посто нном напр жении, при котором в цепь испытательного тока высокого напр жени  включают последовательно сегнетоэлектрический конденсатор и сопротивление и по изменению напр жени  на последнем, обусловленному возрастанием нелинейных свойств конденсатора под действием посто нного тока, судить об интенсивности частичных разр дов и короны в образце.A method is proposed for registering internal partial discharges and corons in dielectrics with a constant voltage, in which a ferroelectric capacitor and resistance are sequentially connected to the high voltage test circuit by changing the voltage on the latter due to the increase in direct current voltage. , judge the intensity of partial discharges and corona in the sample.

На чертеже изображена принципиальна  электрическа  схема устройства дл  осуществлени  предлагаемого способа.The drawing shows a circuit diagram of a device for carrying out the proposed method.

К зажиму / высокого напр жени  присоедин етс  испытуемый образец 2 и последовательно с ним включаютс  нелинейный сегнетоэлектрический конденсатор 3 и измерительное сопротивление 4 (активное или индуктивное), шунтированные делительным сопротивлением 5.The test sample 2 is connected to the terminal / high voltage and in series with it are included a nonlinear ferroelectric capacitor 3 and a measuring resistance 4 (active or inductive), shunted by a dividing resistance 5.

Через разделительный конденсатор 6 сегнетоконденсатор 3 и сопротивление 4 получают питание от источника 7 повышенной частоты. В качестве этого источника может быть использован звуковой генератор. Параллельно измерительному сопротивлению 4 включен резонансный усилитель 8, настроенный на частоту, вдвое большую частоты источника 7. В качестве такого усилител  может быть использован анализатор гармоник, к выходу которого подключен стрелочный прибор. Дл  зашиты устройства при пробое образца в нем предусмотрен газовый разр дник 9.Through the separation capacitor 6, the ferro-capacitor 3 and the resistance 4 are powered from the high-frequency source 7. A sound generator can be used as this source. Parallel to the measuring resistance 4 is included a resonant amplifier 8, tuned to a frequency twice the frequency of source 7. As such an amplifier can be used a harmonic analyzer, to the output of which a switch device is connected. To protect the device during sample breakdown, it provides a gas discharge 9.

Делительное сопротивление 5 выбираетс  с таким расчетом, чтобы посто нна  составл юща  напр жени  на нем имела величину от нескольких дес тых вольта до нескольких вольт или дес тков вольт дл  заданного диапазона испытательных напр жений посто нного тока. В этом случае при изменении сопротивлени  изол ции различных образцов можно использовать одно и то же сопротивление 5. Переменное напр жение выбираетс  с расчетом получени  достаточного сигнала на выходе усилител  8.The separating resistance 5 is chosen so that the constant component of the voltage on it has a value of from several tenths of volts to several volts or tens of volts for a given range of test voltages of direct current. In this case, when changing the insulation resistance of different samples, the same resistance 5 can be used. AC voltage is chosen to calculate the sufficient signal at the output of amplifier 8.

Если в образце не происходит частичных разр дов, то зависимость сигнала на выходе от величины испытательного напр жени  посто нного тока (в испытательном диапазоне) имеет вид горизонтальной пр ; ЬЛЯуТЕIf no partial discharges occur in the sample, then the dependence of the output signal on the magnitude of the DC test voltage (in the test range) has the form of a horizontal voltage; LOOK
