SU1572895A1 - Apparatus for transmitting signals of automatic locomotive signalling - Google Patents

Abstract

This invention relates to automatic locomotive signaling devices. The purpose of the invention is to increase reliability. The goal is achieved by the fact that the device contains time-delay relays 4 and 5, the supply transformer 7, the sectional secondary winding of which is connected to the track rail through contacts 4.1 and 5.1 of relay 4 and 5 and through limiting resistors 8, 9 and 10. The primary winding of the transformer 7 is connected to the alternating current source via terminal 3.1 of the transmitter relay 3. When the train enters the track section, red-yellow light codes are received through the limiting resistor 8 through the limiting resistor 8, after releasing the relay 4 times the signal goes to the rail line the overvoltage resistor 9, when the time relay 5 is released, the codes enter the rail line through the resistor 10, which implements the train movement program along the track section. 1 il.

Description

Personal contact 4.2. Relay 5 time delay 25 speed at any point connected to the power source through contact 4.3 relay 4 and its own contact 5.2. The switch-on code 2 is connected to the power source via the contacts 11–12 of the signal relay (not shown) and the contacts 13 and 14 of the warning relay about 30 meters (shown).

The primary winding of the track transformer 15 is connected to an alternating current source via pin 16 of the signal relay, pin 17 of the approach indication relay, pin 6.1 of the signal relay repeater and pin 18 of the transmitter relay (not shown).

The drawing also shows traffic lights 19 and 20.

The device works as follows. .

When burning at the entrance track of the red light and when the train enters the rail line, the approximation alert relay is turned off and, at 13 p. 14, connects the supply poles to the control box and the red-yellow code fails because the time relay has not yet failed. and the codes will not be submitted from the next control point, which will eventually lead to emergency braking of the train.
