Description

IaArAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA still make appealing the device for automatic svyazhennyh on the crossing of railway lines, equipped with a service provider and a track: a relay, normally energized and shunted when you are close to, moving it to your destination in order to find out what you are looking for, and you are looking for you to find out about cetei. Time relay; Usually, for TOGO, in order for the airport to move to the train, the signal circuit should be wired up - during the course of the train (a sufficient period of time is sufficient for all the train through the crossing. A kacheopve time relay in it is applied a lamp to the grid and cathode of the coach. A co-capacitor is connected to the battery, and the auxiliary relay is switched on in the aldupro circuit.

The drawing shows a diagram of the device.

The connected rails 1с, where the railroad tracks J and R located at the respective distances from the crossing, are connected to the battery circuit of the BZ relay RK and PP. Relb RR serves to halt the signaling value of the nipH train passing, and the RK-dl relay locks the control circuit of Lumina L when the wires of the PP relay break (the PE relay releases measles and closes KOHTai T 11). When the relay PP is triggered

Measles it closes the RP relay circuit & this last connects the coil of the RB relay to the battery circuit via pin 2. Relay PJ5 silences its contacts 7, as a result of which the PPi relay disconnects from the RP relay and switches to the PG relay; In addition, the RB relay is blocked by delaying via -contacts 6 and 10 tons by contact 5 and switches on the signaling lamps of the trunk lines and the calls BF installed on both sides of the crossing. With the same contact you can draw up a chain of cathode CL, to the grid of which a negative 3 is fed through the relay through the help of container 3. the potential from feiaipen B, simultaneously with the charge of the charge, and the high-capacity capacitor C, due to this, the anode circuit of the lamp is opened, the measurine of the relay RA remains released and contact 10 is closed.

If, however, for some reason, the train does not go to another route, and if it does not reach the insulated rail, it will return from section B to section A, the signal lamps at the crossings will be tracked until noica is discharged kondenalror C. Following this, in the anode value of lam11n 1, the current is on; Opens contact 10 and thereby unlocks the relay RB. Reye RB will release its measles, again crushing the chain of signal and cathode lamps by contact 5. The RB relay is then unblocked, since the circuit for 111, Yer 1V. Of it will be disconnected by contact 6. Capacitance of capacitor C is taken up with a large amount of rtyuchet, so that RA would pull its measles only when The past carriage of the train going from A to B will be passed by the nzolirovaniy rail of the section B. Pruid the isolated rail of the section

A, the train, as indicated above, using the relay of the RP and the RB © burns the driving lights at the crossings and turns on the bell. Further, the train runs along the aisle of the junction of the other section, closes the circuit of the PC relay, which blocks the first through the contact through pin 8 and runs 9 the circuit of the unloaded lamps at the crossings. With further train movement to section | y) B, capacitor C is gradually increased and, finally, the current B of the anode circuit - the KL lamp of the dosahedgash is of such a magnitude that the RA relay will start and: disconnects the contactor 10 of the RB relay circuit, and with it rel0 PC. Thus, the entire system comes to the initial use.

There are cases when, following the train, at the last transfer and, at the same time, you had a different contact on the school & The chain of Sigval l-algaes at the crossing, the distance of the buoy very close to it, the second, for example, the lagging behind, pushing locomotive, moves. Then, despite this second napoBoioiM contact of relay 1 of the PP relay, the device will not come into action and the warning signals for the crossing are, so, the C-sensor C is still not completely resolved and the RB relay, but together with mm and 1 relay PC, still blocked

To eliminate this possibility, the RP relay is equipped with pin 4, which is unlocked (1 PCB relay at the first current pulse, which causes the iHa signal lights to move again and: - acoustic signals are heard.

The operation of the device when the food moves from the B to the area A — a pattern does not differ from what has just been added.

On double-track glands, the roads may be reflected, using a simpler device consisting of only two isolated rails, respectively located on the site, x A and

B, - one on the odd, and one on the even path. However, this is a purely two-system system, which can be applied, if not

expects movement along the warlord path.

Capacitor C can be of variable capacitance, so that you can: adjust the blocking time (using the cathode plate) of the RB relay; This time is chosen in 3aBEcnifOCTH from the route profile, train speeds and train lengths. In practice, the device must be located at such a distance from the crossings, so that the train is located on an insulated rail 20-30 seconds before the actual approach to the crossing.

The cathode larshees in the device can be used with two grids to reduce the voltage of the anode batteries. In the event of a city and burnout; control lamps for new ones can be installed corresponding automata. Instead of zvodkhov and lampplates, it is possible to limit yourself only with signal lamps, but in this case it is advisable to install a detector for starting the ignition and extinguishing of two lamps on each side.

Led not fear the damage to the system from. It is possible to limit the installation of the relay to the isolated RSLs by setting the relay to the operating current, as is often done in similar devices. In this case, the insulated rails and relays PE and PP are removed, and pin 1-relay PP is simply a pedal switch.
