Известны устройства дл  защиты электроустановок , содержаш,ие чувствительный элемент с двум  обмотками, включенными встречно. Известные устройства недостаточно надежны и завис т от параметров защищаемой электроустановки.Devices are known for protecting electrical installations, comprising a sensitive element with two windings connected in opposite. The known devices are not reliable enough and depend on the parameters of the protected electrical installation.

Предлагаемое устройство дл  защиты разр дной цепи генератора имлульсов тока, с целью устранени  этих недостатков, снабжено индуктивно св занным с разр дным током двухплечевым датч.иком-иитегратором, обмотки которого через противоположно направленные диоды .подключены к параллельно соединенным конденсаторам и обмоткам упом нутого чувствительного элемента.The proposed device for protection of the discharge circuit of the generator of current impulses, in order to eliminate these drawbacks, is supplied with a double-arm sensor connected to the discharge current by a comic and integrator, the windings of which are connected through parallel-connected diodes to the windings of the sensing element .

На чертеже показана прнициниальна  схема предлагаемого устройства.The drawing shows the practical scheme of the device.

Датчик-интегратор устройства содержит две обмотки / и 2.The sensor integrator of the device contains two windings / and 2.

Конец обмоткн 2 и начало обмотки / соединены с общ.нм выводом. К каждой обмотке У и 2 через нротивонолои но направленные дноды 3 Н 4 подключены конденсаторы 5 н 6 и обмотки пол ризоваиного реле 7.The end of the winding 2 and the beginning of the winding / connected to the common output. To each winding, U and 2, capacitors 5 and 6 and windings of the polarization relay 7 are connected via the opposite direction of the 3 H 4 bridge.

Поскольку схема настроена на срабатываннеthe contact group of the relay 7 operates at a given (or greater) ratio of the half-wave energy of the discharge current corresponding to the given (or greater) current overload. Since the circuit is set to fire
