DEVICE OF RAMIFIED RAIL CHAIN WITHOUT INSULATING BUTT JOINTS Russian patent published in 2009 - IPC B61L23/16 

FIELD: transportation.

SUBSTANCE: invention is related to railway automatics and may be used in systems of interval control of subway trains movement. Device comprises track generator (6), which is electrically connected to capacitor (9), the first track receiver (7), inlet of which is connected to rails of the first ramification (2), the second track receiver (8), inlet of which is connected to rails of the second ramification (3), the second and third capacitors (10 and 11). The first capacitor (9) is connected serially to the outlet of track generator connected to rails of non-ramified end, with creation of the primary oscillating circuit. The second capacitor is connected serially to the inlet of the first track receiver with creation of the secondary oscillating circuit in the first ramification. The third capacitor is connected serially to the inlet of the second track receiver with creation of the secondary oscillating circuit in the second ramification. Values of capacitor capacitances satisfy the conditions of resonance of every out of three joined oscillating circuits at bearing frequency of rail line control signal.

EFFECT: simplification of device circuit and higher reliability of operation of ramified rail chain.
