FIELD: railway signalling system; signalling, interlocking and blocking devices; branched track circuits coded by ACS currents. SUBSTANCE: device has tracks 1 with insulated rail joints, rail bonds, points and crossing and branch adjoining main station track 1.1 and side station track 1.2, track circuit signals supply source 2, track circuit signals receivers 3, 4 connected to each branch of rail track with track relays 5, 6 connected at outputs. Code closing exit route relay 8 and ACS signal supply source 9 are connected to track in series with track circuit signals supply source 2 and track circuit signals receiver 3 of branch track 1.1 adjoining main station track through contact 8.1 of code closing exit route relay 8 and entrance route contacts 10.1 through filter in form of stopping capacitors 11. Introduced into circuit additionally is branch track occupancy control relay 7. Placed in supply circuit of relay 7 is front contact 6.1 of switch track relay 6 of branch track 1.2 adjoining side track. Connected in parallel with the latter is circuit with series-connected front contact 7.1 of branch track occupancy control relay 7 and resting contact 5.1 of switch track relay 5 of branch track 1.1 adjoining main station track. Placed in supply circuit of code-closing exit route relay 8 are front contacts 7.2 of branch track occupancy control relay 7. EFFECT: enhanced safety of traffic owing to prevention of possibility of connection of ACS signals to track circuit when locomotive passes from side track or shunting of track circuit by vehicle on side track in case of short circuits in insulated rail joints. 1 dwg |
