TONAL RAIL CIRCUIT DESIGN WITH ISOLATING JOINTS

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to railway automatic control-and-telemetry systems to be used in railway traffic spacing control systems built around tonal rail circuits (TRS) with isolating joints on railway sections equipped with DC and AC propulsion systems. Proposed device comprises TRS receiver and transmitter connected with rail circuit. Additionally, units to transmit propulsion current from given rail circuit into rail circuit of adjacent track are mounted arranged on nonmagnetic material frame. Said units are made up of steel wires with their ends connected to rails at connections with rail circuit of TRS receiver and transmitter. ^ EFFECT: higher noise immunity and reliability in carrying back propulsion current. ^ 1 dwg
