Figure 1 presents the scheme of protection from interference power lines, which shows a positive 1 and negative 2 pole power supply, relay match 3, front contacts of relay presence code 4, the third counter 5, the relay green fire 6, relay red-yellow fire 7, a resistor 8, a condenser 9, the contact of the impulse relay 10, the reverse pulse repeater relay 11, estrogenically diode 12, estrogenically resistor 13, the contact of the reverse repeater 14, an additional resistor 15, an additional diode 16, the first additional capacitor 17, the second additional capacitor 18, the third additional capacitor 19, fourth capacitor 20, a fifth capacitor 21, the speed gauge 22, the first 23 and second 24, third 25, 26 fourth account is you speedometer. The circuit elements are connected as follows: plutonomy pole 1 power source through front contacts of relay presence code 4, the third counter 5, the relay green fire 6 is connected to the anode of the additional diode 17 and front contact of relay red-yellow fire 7, a common contact which is connected to the first pole of the resistor 8, the first output winding of the relay line 3, the second terminal of which is connected to the minus pole of the power source 2 and the first pole of the capacitor 9, the second pole of which is connected to the second pole of the resistor 8, the cathode additional diode 17 is connected to the rear contact of the reverse pulse repeater relay 14, front contact of which through the additional resistor 15 is connected with the positive pole 1 power source, and the first findings of the first 23 and second 24, third, 25, 26 fourth contacts of the speed gauge 22 and the first pole of the first additional capacitor 17, the second pole of which is connected to the minus pole 2 power source, the first output winding of the reverse pulse repeater relay 11, the cathode isregistered diode 12 and the second poles of the second 18, 19 third, fourth 20 and 21 additional fifth capacitor, the first pole of the second 18, 19 third, fourth, 20, 21 fifth additional capacitors are connected accordingly, with the second pins PE the first 23, the second 24, third, 25, 26 fourth contacts of the speed gauge 22, the anode isregistered diode 12 is connected with the first pole isregistered resistor 13, the second pole of which is connected with the second output winding reverse repeater 11 and the rear contact of the impulse relay 10, a common contact which is connected with the positive pole 1 power source. The device operates as follows. When the excited state relay line 3 of the circuit from the positive pole 1 power supply through the relay contacts of the presence of code 4, the third counter 5, the relay green fire 6 when receiving a code green fire (or other circuits in other situations) [A.A. Leonov maintenance of automatic locomotive signaling. M.: Transport, 1982. - 256 S. (s, RES)]) has an additional circuit to generate the deceleration at occurrence of interference from power lines, which is created from charged an additional capacitor 15 through the rear contact of the reverse pulse repeater relay 14 and the additional diode 17. The charge circuit of the additional capacitors 17, 18, 19, 20 and 21 creates a front contact of the reverse pulse repeater relay 14, the first - fourth contacts 23, 24, 25, 26 speedometer 22 and an additional resistor 15 from the poles 1 and 2 of the power source. The power supply circuit of the winding of the reverse pulse repeater relay 11 is created for Shatilova contact of the impulse relay 10 from the poles 1 and 2 of the power source.

If the deceleration of the reverse pulse repeater relay 11 exceeds the pulse duration, the relay 11 is de-energized, additional capacitors 17-21 can be continuously charged. If the pulse width exceeds the deceleration relay 11, i.e. subject to interference, the relay 11 is de-energized, its rear pin 14 connects the charged capacitor 17 or more capacitors 18-21 through the diode 16 and the contact 7 to the winding of relay 3. The number of connected capacitors defines additional down time relay 3, during which the locomotive decoder does not respond to a hindrance than excludes the impact of interference on the operation of automatic locomotive signaling. Items 8 and 9 create estrogenically chain and attach relay 3 deceleration. The elements 12 and 13 create estrogenically circuit for relay 11 slow. The number of active capacitors depends on the speed of the train. The higher the speed, the smaller the number of capacitors included, the less additional is Amelina the relay match 3. When exposed to interference from power lines when the relay 11 is de-energized, the relay match 3 receives an additional slowdown [Leonov, A.A. maintenance of automatic locomotive signaling. M:. Transportation, 1982. - 256 S. (s, RES)]). To eliminate dangerous situations when ground sintering contacts reverse pulse repeater relay 11, the resistance of the additional resistor 15 cannot be less than 30,000 Ohms, to avoid holding the armature of the relay match 3 in a drawn condition.
