(54) УСТРОЙСТВО ДЛЯ ОБНАРУЖЕНИЯ ОБРЫВА ЖИЛ КАБЕЛЕЙ В МЕСТАХ РАСПАЙКИ . .... 3. кабел  зар дный ток ничтожно мал, транзистор Закрыт и индикатор не горит. Устройство дает возможность обнаруживать обрыв жилы кабелей как с экранированной оболочкой , так и без нее при любом зазоре между оборванными концами жилы. . Формула изобретени  Устройство дл  обнаружени  обрыва жил кафл й , например с экранированной оболочкой, в haecrax распайки, содержащее источник напр жени  и индикатор, отличающеес  тем, что, с целью расщирени  функциональных возможнос4 тей, в него введены регулируемый резистор, )езисторы , транзистор, диод и тиристор, причем база транзистора соединена с выходом устройства, соединенным с контролируемым кабелем непосредствещю и через регулируемый резистор с одним из полюсов источника напр жени , с которым через первый резистор соединен эмиттер транзистора, коллектор которого через второй резистор соединен с другим полюсом источника напр жени  и катодом тиристора и непосредственно - с анодом днода, катод которого через третий резистор соединен с управл ющим электродом тиристора, анод которого через индикатор соединен с одним из полюсов источника напр жени .(54) DEVICE FOR DETECTION OF THE CLUTCH OF LIVES OF CABLES IN PLANE PLACES. .... 3. Cable The charging current is negligible, the transistor is closed and the indicator is off. The device makes it possible to detect cable breakage with or without shielded sheath with any gap between the broken ends of the core. . Claims A device for detecting a wire break, for example, with a shielded shell, in the wrap-up haecrax, contains a voltage source and an indicator, characterized in that, in order to expand its functionality, an adjustable resistor is inserted into it, and a thyristor, the base of the transistor connected to the output of the device, connected directly to the monitored cable and through an adjustable resistor to one of the poles of the voltage source, to which the em is connected via the first resistor ter transistor having its collector via a second resistor connected to the other pole of the voltage source and the cathode of the thyristor and directly - with the anode dnoda cathode which through a third resistor coupled to the control electrode of the thyristor, the anode of which through the LED connected to one of source voltage poles.
