Abstract

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

The invention relates to devices for signaling, centralization and blocking in railway transport, and in particular to branched station rail circuits encoded by ALS currents. The technical result achieved is to exclude the possibility of connecting ALS signals to the rail circuit when the locomotive leaves the rail circuit from the side track or when the branched rail chain is shunted by rolling stock located on the side track when the insulating joints exit (short circuit). The task of improving the safety of train traffic is solved due to the fact that the device containing rail tracks 1 with insulating joints, rail connectors, turnouts and branches that are adjacent to the main 1.1 and side 1.2 station tracks, the power supply of the signal of the rail circuit 2, receivers rail network signals 3.4, connected to each branch of the rail track, the output of which includes track relays 5 and 6, the code-including relay of the route of departure 8 and the power supply of signals A C 9 are connected to the rail track in series with the power supply of the signals of the rail circuit 2 and the receiver of the signals of the rail circuit 3 of branch 1.1, adjacent to the main station path with contacts 8.1 of the code-enabling relay of the departure route 8 and the reception route through the filter in the form of separating capacitors 11, additionally introduced branch occupation control relay 7. An occupation control relay 7 power circuit includes a front contact 6.1 of the arrow track relay 6 of branch 1.2, adjacent to the side station path. Parallel to it, a circuit is connected from the front-mounted contact 7.1 of the branch occupation control relay 7 and the rear contact 5.1 of the arrow track relay 5 of branch 1.1 adjacent to the main station path. In the power circuit of the code-enabling relay of the departure route 8, the front contacts 7.2 of the control relay for seizing the branch 7. 1 are included.
