SU93075A2 - Device for double-track relay semi-automatic blocking - Google Patents

Description

The main author's certificate No. 69453 describes a device for single-track semi-automatic blocking based on the use of relay dependencies.

The proposed device, using the principles underlying the device according to the author's certificate No. 69453, relates to double-track semi-automatic blocking systems.

The main difference of the proposed semi-automatic interlocking system is that in order to charge a linear circuit from extraneous currents and to block with one line wire, with a free span, the linear relays of the sending and receiving stations are energized by the current from two batteries connected in line stations, and when the line is occupied, the linear relay of the receiving station is disconnected from the line for the entire duration of the train travels.

FIG. 1 is a schematic diagram of the linear circuit of the proposed device; in fig. 2 - local circuit diagram; in fig. 3 is a schematic of the track circuit and in FIG. 4 - lamp circuit diagram.

The device for double-track relay semi-automatic blocking consists of two main parts - linear and local. The linear part of the system at each of the stations, limiting the double track distillation {Fig. 1), consists of a linear relay

type KR-1, installed at each station. The linear relays are connected to each other by a linear wire using earth as the second wire. KR-1 linear relays are designed to transfer interlocking signals between

stations and normally are under current, and at this time the sources of electricity (batteries) of both stations are switched on in series.

The local part of the system at the station that sends the trains (Fig. 2) includes the alarm relay CHUR, the anti-relay CP relay and the PIR preliminary notification relay.

The signal relay CHUR is designed to control the output traffic lights. The anti-repetitive control relay provides anti-recirculation of the output lights. The PIR preliminary notification relay automatically marks the entrance of the sent train to the camp “72 .75 5 /

The reception unit prepares a circuit at the sending station for receiving a blocking arrival signal.

The control and exit lights automatically close.

The duty officer under Art. A puts the handle of the output traffic light in the normal position and reports by telephone to Art. about the departure of the train.

The duty officer under Art. B prepares the route for receiving the train and opens the traffic light. After following the train taken by an isolated rail at st. The YAZ lamp goes out and the Ya lamp lights up.

The duty officer under Art. B closes the entrance traffic light and, having been convinced of the full complement of the received train, presses the NR button, as a result of which the PS lamps light up at both stations and the YaZh lamp at station A and the lamp Z at the station B. le PR and the isolated rail relay go out. constituting the rail circuit (Fig. 3). To monitor the condition of the haul and the position of trains at the stations, control lamps are provided (Fig. 4): PS - the stage is free, / 75 - the stage is occupied and I (at the receiving station) - the train arrived and the station. The movement of trains from the station. L to Art. 5 shall be carried out in compliance with the following procedure: Duty officer under Art. And it opens the output traffic light, as a result of which, at the stations L and B, GASNZTLA.MPA PS and light the KAZ lamps. When the train leaves for a stage, the rail pedal is activated. After that, the duty officer of art. B notifies by telephone the duty officer under Art. And about the arrival of the train.

During the above operations, the electrical circuit operates as follows.

In the normal position, the linear relays at both stations are under the current flowing through the circuit: plus batteries per station. B-4}, 42IR-12, PLR-1, 2LR-63, 61PR and 121, 122 LR-32, 5NUAR - line wire -2, SR-11, 13PIR-2}, 22PRR-23, 2 / UUR- minus plus battery na art. L-41, 43 CHUR-land at st. And the same on st. B-52; 51 IR - minus battery per st. B.

When you open the output traffic light at the station. And, when a current begins to flow through the CHUR signal relay, switching occurs in the linear and local circuits at stations L and B, namely:

a) at art. L in the linear circuit the battery poles are switched;

b) in connection with the switch to art. L contacts of the CHUR relay; both linear relays remain without current;

c) contact //, 12LR on Art. The battery is also broken at st. B is disconnected from the linear relay of the Republic of Latvia, which is connected to the ground with its contact 11, 13 of the Republic of Latvia.

At the next moment, the polarized measles of both -linear relays are transferred over the circuit: plus batteries per st. А-41, 42ЧУР-22, 21ППР-13, 11ПИР-1, 2ЛР-linear wire - 31, 32ИР-61, 63ПР and 122, 121ЛР-2, 1ЛР-11, 13ЛР-21, 95Я / СР - earth per station . B -10 at st. A-22, 21 CHUR - - Battery Minus.

At the same time at st. -b the contact 111, 112LR is broken (see Fig. 3) and the relay IR is left without current, as a result of which at st. B disconnects from the line the linear relay LR and the switching of the battery poles in the linear circuit occurs (see Fig. 1). After switching the battery poles in the linear circuit, the current of the reverse direction is established and after the deceleration of the SPR relay to st. L (see fig. 2) the latter releases measles and, by breaking contact 21, 22PRM, turns off the b & tarey on art. L

from the line (the SPR relay is left without current due to the break of the contact 121, 123ЛР when transferring the polarized core).

As a result of these switchings, the linear relay LR Art. L, on which the output traffic light is open, will flow around the current passing from the battery st. B on pepi: minus battery per st. B-51, 53IR-33, 31 IR - linear wire - 2, 1 LR-P, 13 PIR-21, 23 PPR-land at st. The same on st. B -43, 41IR, plus batteries.

After opening the traffic light duty on art. B and following the arriving train of an insulated rail through the IG relay begins to flow, causing it to switch the battery poles with its contacts and at the same time turn off the current from the linear circuit.

At this time, on art. L (see Fig. 2) is energized by a pre-notification relay preparing a circuit for receiving a "arrival" blocking signal.

When closing the duty but Art. At the entrance traffic light, he presses the supply button for the NR, in connection with which the arrival supply chains are established — local and linear.

According to the local circuit (see Fig. 3), the CRP relay is energized along the following circuit: PB-12-51, 52PR-21, 22IR-11, 12PP-CRR-MB12 relay.

The linear circuit is given a blocking signal, "arrival along the circuit: plus batteries per st. B-41, 42 IR-31, 32 PKR-21, 234-62, 61 PR-32, 31IR - linear wire - 2, 1LR - 1}, 12P IR-earth at st. L - the same at st. B-52, 51 HP - minus battery.

After the transfer of the polarized linear relay to the station L, an SPR relay is energized and the DIR turns on, which releases the measles after the set delay has elapsed, as a result of which a battery st. L.

At st. B after the transfer of polarized core linear relay

The battery is connected to the linear circuit via pins 12, 11LR and 121, 122LR. The polarized cores are transferred by pressing the button of the PP circuit: plus batteries 41, 42IR31, 32 PKR-21, 23 41, 2LR121, 123LR-52, 51IR-minus batteries .

After releasing the PP button, the PKR relay releases the measles when the deceleration time has elapsed and the circuit returns to the normal state shown in FIG. 1-4.

Thus, in the proposed semi-automatic blocking system, one KR-1 type linear relay for each main route is provided for transmitting blocking signals between stations on each of them. In this case, the linear relays of one main path are connected by a linear wire using earth as the second wire.

Normally, the linear relays of both stations are energized, with the batteries of both stations connected in series in a linear circuit.

Opening the output signal at the station sending the train is only possible when a current passes through a linear relay of a certain direction, and at the moment the output traffic light opens, the current direction in the linear relay should be reversed while disconnecting the line relay from the line of the receiving train.

Receiving a blocking signal "Arriving at the station sent by the train, is possible only if there is an auxiliary preliminary notification relay on it.
