The device works as follows.

In the initial position, the position of the arrow is monitored and, if the receiving-signal unit 4 is turned on, on the arrow the warning signals are received: the control, if the arrow is not in the route, and the danger signal

when the arrow enters the route after the route relay is de-energized.

The control, for example, of the plus position of the arrow, is carried out as follows. The alternating current voltage from the control circuit 7 is fed to the winding of the polarized control relay 6 and then through the three-dimensional contacts 2.3 and .2.4 of the switch start relay and the communication line 5 to the directional electric drive 3, where the secondary valve shunts a negative, half-wave alternating current. A polarized control relay 6 from an uncoupled positive half-wave of an alternating current is triggered, and the pollenized measles takes the position corresponding to the positive position of the arrow. In this case, in the starting block 1, a positive control relay is activated, which ensures the control of the positive position of the arrow.

Simultaneously with the control of the position of the arrow, the passage of warning signals is ensured. If the arrow is not in the route, the arrow relay routing is energized from the warning signal transmission unit 16 via the contact 13.5 of the blocking relay 13 to the input of the transition unit 17 and then from its output through the rear contacts 2.3 and 2.4 of the switch start relay and the communication link 5 the control signal enters the receiving-signaling unit 4, where it is detected and converted into light and sound signals. If the arrow is in the route, then the de-energized route relay switches (replaces) the control signal to the danger signal.

When translating the arrow in the starting block 1, the switch start relay is activated and through its front contacts 2.1. and 2.2. the starting current from the start-up unit 1 passes through the link 5 to the electric drive 2 arrows and translates it into a minus position. When the switch is turned, the polarity of the rectifying valve that shunts the already positive half-wave of the alternating current shifts one-time, temporarily, and as a result, the control relay 6 moves its polarized contacts to the minus position. In this case, instead of the arrow plus control relay, the switch minus control relay works, providing control of the negative position of the arrow.

Conversion from negative to positive is done similarly.

When locking the switch section, the station duty officer on his console presses the lock button 8. In this case, contact 8.2 of button 8 breaks the circuit of the first high-resistance winding of the blocking relay 13, and it lowers the measles, its contacts 13.1, 13.2 and 13.5 open, and contacts 13.3, 13.4 and 13.6 close. Through contact 8.3 of the button 8 and contact 13.3 of the blocking relay 13, the auxiliary relay 14 is energized on the second winding, while the polarized switch is shifted to the locked position, contact 14.1 is opened, contact 14.2 is closed. The signal lamp 11 is formed through the second low-resistance winding of the blocking relay 13. The warning lamp 11 lights up ... Although the current through the second low-volume winding of the blocking relay 13 flows, it is not sufficient in magnitude to operate. A signal lamp 9 is ignited through contact 13.4. Contact 13.7 breaks the winding circuit of the switch track turnips and it fails to operate, and therefore no train routes can be assigned to this section. By contact 13.8 of the blocking relay 13, the winding circuit of the starting switch of the security arrow is broken. Before unlocking the track, the security arrow cannot be transferred. In addition, switching contacts 13.5 and 13.6 of the blocking relay 13 switch: the signal transmission unit 16 from the input of the transition unit 17 is turned off and the additional signal transmission unit 18 is connected instead. At the same time, through a block 17, into a two-wire line 5 and further into a receiving-signaling unit 4, a blocking signal is received, which is reproduced in the form of light and sound signals.

The station attendant on a burning lamp 9 on one of his console makes sure that the switch section is blocked. After blocking the duty officer, the station cannot unblock the turnout station without a share

If it is out of button 8 on its console, then the circuit of the second winding of the auxiliary relay 14 is de-energized, but the polarized contacts remain in the same position, no changes in the circuit occur.

The work supervisor convinces of blocking by three signals: by the burning lamp 11, by the light and sound signals of blocking. reproducible receiving-signal unit 4, located on the arrow.

When unlocking, the station attendant pulls out button 8, and the work supervisor presses button 10 and releases. When the button 10 is pressed, a resistor 12 is introduced into the circuit instead of the lamp 11, which has a much smaller (several times) electrical resistance. The current of the second low-resistance winding of the blocking relay 13 will have several times greater current, from which the blocking relay 13 triggers and with its contact 13.T restores the high-resistance winding circuit, which remains energized even after releasing the unlocking button 10. The blocking relay 13, having turned on the current, switches its contacts 13.1, 13.2, 13.5, 13.7 and 13.8, which close, and contacts 13.3, 13.4 and 13 6 open. Auxiliary relay 14 becomes energized on the first winding and the polarized terminal. Lines 1.4.1 and 14.2 are moved to the unlocked position. The circuit returns to its original position.

The station attendant is convinced about the unblocking of the arrow section by turning off the lamp 9 (on his console), and the work supervisor is convinced by turning off the lamp 11 when the button 10 is released and according to the blocking signal for warning signals.

The rear contact 15 of the positive control relay of the security arrows serves so that the repaired switch section can be blocked only in the positive position of the security arrows. The polarized contact 14.1 of the auxiliary relay 14 protects the circuit from an arbitrary blocking in case of a short-term loss of the power supply voltage.
