Abstract

The invention relates to railway automation and telemechanics. The purpose of the invention is to increase the reliability of the device. To change the direction of motion, you need to press the change direction button at one of the stations, as a result of which the other station controls the free drive of the haul and de-energizes the directional relays, excites the additional station freewheel station relays, doubles the voltage in the line, and boosts the relay control of the direction of movement fixes the change of direction of movement. Each directional switch is triggered by the passage of a current of a certain polarity. Station directional control relays are disconnected from the line wires. 3 il. co-eaten with O5 00

The device works as follows.

In the main mode of changing the direction of motion, when prior to the beginning of the process of changing the direction of the relays 12 and 49 of station 2, the relay 7 of station 1 and the corresponding distillation relays 19 and 25 are energized, the button 16 is pressed at station 2 and the relay 18 is energized than at the opposite stations 1, standing in the “Departure” position, de-energize relays 7 and connect station relays 5 and 9 to the line wires 3 and 4.

At station 2, disconnect relays 12 and 49 simultaneously.

When de-energizing the slow-acting relay 12, a reverse power supply circuit is created from station 2 via contacts 43.2 and 43.3 of relay 43,

series-connected low-resistance windings of all distillation relays 19 and 25 and series-connected windings of station relays 5 and 9.

In this case, the station branch of station 9 of station 1 is triggered.

In this case, station relays 32 and 33 switch their polarized cores from the normal position to the translated position and fix station 1 turn from the position “Departure to the position” Reception. At the same time, the relay 17 is de-energized by connecting contacts 17.1 and 17.2 to the linear circuit of relay 11.

In this case, the voltages of the linear source 22 of station 1 and of the source 23 of station 2 of warehouses are. The magnitude of the linear current in the direction of the beginning process of changing the direction of the distillation signal systems is doubled, and the distillation relays 19 and 25 reliably record the change in direction of movement.

5 At the receiving station 2, the repeaters 43 and 44 are sequentially de-energized, and the inclusion of the reverse polarity in the linear circuit is maintained until the de-energization of the relay 43 of the station 2

reception.

When de-energized at station 2, the reception of the relay 43 to the linear circuit is connected with relays 6 and 10. By plugging in the current from the linear source 22 of the opposing station 1, the relay 10 with its contacts 10.1 and 10.2 closes the excitation circuit of the relay 47 and 48. Switching polarized Corr station relays 47 and 48 from the translated position to the normal one fixes the transfer of Station 2 from the position to the Reception to the Departure.

0 The station attendant receives on the console-panel a notification of the end of the station turning cycle in the "Departure - indicator light 53 of station 2" position and the light bulb 54 lights up.

Device to change direction

5 train movements are constructed using a two-wire cable line, in which, on the span, at each signal installation, low-ohm windings of two relays 19 and 25 are connected in series.

0 passing the current of its polarity. In order to memorize the direction of movement according to the local scheme, relay 26 is additionally turned on. When the position is tinted, relay 25 receives relay 26 directly polarity. In the de-energized or undercut state of the relay 19 and 25, the winding of the directional relay 26 is disconnected, ensuring the position of the polarized core remains unchanged and corresponds to the previously obtained current direction.

At each signal installation, the line wires 3 and 4 include the pins 20 and 21 of the track relay. With a train free train and a good circuit, the directional circuit at station 1, standing in the “Departure” position, is connected to the low-resistance winding of relay 7. The relay 5 and 9 of Station 1 is left to “Departure from the directional circuit, disconnected.

At the line 2 receiving station 2, low-impedance windings of relays 12 and 49 are connected in series. Polar relays 12 and 49 are used to increase the circuit's protection against operation of station station relays with a bipolar recharge circuit from an external power source.

In the absence of trains on the stretch, the closed output traffic lights at the departure station 1, the exclusion relay 31 is energized and, with a healthy linear circuit, the corresponding span direction relay 25 is energized, ensuring that the signal installation is activated in the set direction.

At station 1 of the sending, the relay 7 is energized, at station 2 of the receiving under current of relay 12 and 49. These relays provide optical active control on the station attendant control panel — indicator lights 41 and 56 at station 1 and receive 2 are switched on from sources 13 and 14.

When the free span and the serviceable circuit are powered, the directional circuit is supplied from the station 1 standing at the Departure.

The relays 5, 6, 9 and 10 n. Of the receiving 2 and departure 1 stations from the directional circuit are disconnected, which ensures that the established direction remains unchanged when electromagnetic lines are applied to the line.
