(54)(54)

ПОМЕХ HITTER

Таким образом, мешающие напр жени , наводимые контактной сетью 2 и обратным проводом 1, взаимно уничтожаютс  в линии св зи 15. -, ,Ф о р м у л .а и 3 о Р ...T.f.. Устройство дл  защиты линий св зи от помех, содержащее обратный провод, про ложенный вдоль контактной сети, трансформаторы и конденсаторы, отличающ е е с   тем, что, с целью компенсации индуктивного магнитного мешающего вли ни  контактной сети посто нного тока на линии св зи, одни из концов первичных обмоток трансформаторов подключены че°рез конденсаторы к контактной сети, а одни из концов вторичных обмоток трансформаторов - к обратному проводу, рри этом другие концы первичных и вторичных обмоток трансформаторов заземлены,Thus, the disturbing voltages induced by the contact network 2 and the return wire 1 are mutually destroyed in the communication line 15. -, ..., F o rm y la. And 3 about P ... Tf. Device for protection of communication lines from interference, containing a return wire laid along the contact network, transformers and capacitors, different from the fact that, in order to compensate for the inductive magnetic disturbance of the contact network of direct current on the communication line, one of the ends of the primary windings of the transformers are connected through ° cut capacitors to the contact network, and one of s secondary transformer windings - the opposite wire RIR that the other ends of the primary and secondary windings of the transformers are grounded,
