Description
ность конденсатора 1 св зи, к которой припа Ны провод 12, соедин ющий верхний зажим 13 раз|р дни«а 5 и один вывод первичной обмотки 2 согласующего трансформ-атора. Вторые выводы первичной и вторичной обмоток 2 и 3 согласующего трансформатора и нижний зажи)м 14 разр дника 5 соединены с земл ным зажим 15 устройства. Первый вывод обмотки 3 согласующего траисформатора вл етс высокочастотны зажимом 16 устройства .The capacitor of the coupling 1, to which the wire 12 is attached, connects the upper terminal 13 times | p days 5 and one output of the primary winding 2 of the matching transformer. The second terminals of the primary and secondary windings 2 and 3 of the matching transformer and the lower terminal) m 14 of the bit 5 are connected to the earth terminal 15 of the device. The first terminal of the winding 3 of the matching transformer is a high frequency terminal 16 of the device.
Элементы иаст ройни выбирают с учетом емкости конден1сатора св зи в зависимости от требуемой полосы пропускани и условий согласовани с высоковольтной кабельной сетью и с высокочастотной аппаратурой ов зи и телемеханики. Конденсатор св зи изолирует элементы настройки от высокого напр жени кабельной сети.The elements of the astronomical circuit are chosen taking into account the capacitance of the coupling capacitor depending on the required bandwidth and the conditions of matching with the high-voltage cable network and with high-frequency over-voltage equipment and telemechanics. The coupling capacitor isolates the setting elements from the high voltage of the cable network.
В нор;мальном рабочем режиме при подключении высочсовольтного зажима 11 устройства к сети 6-10 кВ токи промышленной частоты не проход т к зажиму 16, в то же врем дри подключений зажима 16 к источнику токов высокой частоты (передатчи ку) устройство ,не преп тствует прохождению токов высокой частоты в рабочей полосе. Рабочее затухание высокочастотного сигнала в полосе пропускани не превышает 1,7 дБ. В аварийном режиме при пробое радиотехнического конденсатора 1 св зи разр дник 5 срабатывает , шунтиру элементы настройки, и предохран ет их от высокого напр жени .In normal operation, when the high-voltage terminal 11 of the device is connected to the 6-10 kV network, industrial frequency currents do not pass to the terminal 16, while the device does not interfere with the connection of the terminal 16 to the source of high-frequency currents (transmitter) the passage of high frequency currents in the working lane. The working attenuation of the high-frequency signal in the passband does not exceed 1.7 dB. In emergency mode, when the radio capacitor 1 is broken through, the arrester 5 is triggered by shunting the setting elements, and it prevents them from high voltage.
Использование описываемой конструкции позвол ет значительно снизить габаритыThe use of the described design allows to significantly reduce the size
