At the transmitting end of the track circuit, voltage converter 19 is connected to source 2, and output through contact 1.2 and capacitor 20 is connected to relay 9. winding is installed at the receiving end transmitter repeater 21 with contacts 21.1 21.2, synchronization relay 22 with contact 22.1, transformer 23, pulse receiver 24 with contacts 24.1, 24.2, linear transformer 25, the primary winding of which is connected in series to the dome line 17, and the secondary connected to receiver 24, contact 24.1 of which is connected to the resistor 26 and relay 18 is connected in parallel, and one winding of relay 21 is connected to its contact 21.1, the other winding through contact 7 is connected to source 13, which is connected in parallel through contact 22.1 of relay 5. The capacitor 15 is connected to the winding of the relay 22, one output of the winding of the relay 22 is connected via contacts 8 and 21.2 to the middle output of the secondary winding of the transformer 23, another output of the winding of the relay 22 to the contact 24.2 of the receiver 24, the closing and opening contacts of which are connected to the primary winding of the transformer 23, the secondary winding of which is connected to the capacitor 16 and the switching contact 18.1 of the relay 18, the common output of which and the middle point of the primary winding of the transformer 23 are connected to different poles of the source 13. The protective blocks 27 are connected one of its conclusions to

rails own rail line, and others - to the rails adjacent rail line.

The device works as follows.

With a free track circuit, it is powered by DC pulses from voltage source 2 via terminal 1.1 of the transmitter one. Pulse track relay 18 senses these pulses from the converter via terminal 12 of the transmitter 12. AC pulses are sent to the linear circuit, which are sensed by the pulse receiver 24 by the linear transformer 25. Since the power of the pulse track relay 18 and the receiver 24 of the pulse relay is supplied through the contacts of transmitter 1, these relays work synchronously. The synchronization relay 22 will be energized only if the contacts of the pulsed traveling relay 18.1 and the receiver 24.2 are closed and open at the same time. Through contact 22.1, the synchronization relay 22 provides a control relay 5, which gives information about the freedom of the track circuit. When a pulsed traveling relay 18 is excited from any interference, the synchronization of the contacts 18.1 and 24.2 will be disturbed, which will cause the synchronization relay 22 to be set and then the relay 5.

When the current of the electrochemical effect appears in the range of the power supply of the rail circuit, the pulse track relay 18 will reliably de-energize, since a resistor 26 will be connected parallel to it in the interval via pin 24.1 of the pulse relay 24, which reduces the current passing through the track pulse pulse relay 18. Thus, protection against the current of the electrochemical effect is realized.

When the train enters the rail circuit, a pulse track relay 18 is provided, the closure and opening of its contact 18.1 is stopped, which leads to de-energizing the synchronization relay 22. Relay 5 through contact 22.1. Relay 22 is also de-energized. With its contacts 5.1, relay 5 closes the power supply circuit of the code transformer 12, and 5.2 and 5.3 interrupts the power supply circuit of the linear relay 9. Receiver 24 continues to operate from converter 19 through the emitter transmitter 1.2. The occurrence of interference caused by contact 6 of the transmitter relay causes excitation of the pulse track relay 18. But since the closure and opening of contacts 18.1 and 25.1 do not coincide, the synchronization relay 22 remains de-energized, and therefore the relay 5 remains de-energized, gives reliable information about the load on the track circuit. No coding breakdown will occur.

With the release of the track circuit in a large interval of code signals, when

pins 8 of the transmitter relay and 21.2 of the slow acting repeater 21 of the transmitter relay are closed, the synchronous operation of pins 18.1 and 24.2 is resumed, the synchronization relay 22 is energized, and then also the relay 5. The contacts 5 of the relay 5 open the power supply of the code transformer 12, stop coding, contacts 5.2 and 5.3 closes the power supply circuit of the linear relay 9.
