A tetele, the output of which, output 1 1 of the comparison, is connected to the input b, choke 13 of the motor control terminal 14, and the other input to the sensor 15 of the current of the propulsion motor.

Block 13 drive motors consist of a regulator of current 16 and a thyristor converter .17 with a node, m 18 U11, and

Input 1cog1: o, block 12 is connected via a line to the output of sensor 15 of the current of a thruster engine, the low-power locomotive.

The device works as follows.

When the current tia of the lead locomotive 1 is set by the current setter 5, the block 10 creates a circuit with the setpoint adjuster 4 and one of the inputs of the comparison element I1 of the lead locomotive I, on the driven locomotive 2 nj) H this creates a gap between the current sensor 15 of the lead1 0 locomotive 1 and one of the inputs element 11 compare slave locomotive 2 through the communication line, according to block 12 and block 10.,.

In this case, the set of equipment of the slave locomotive 2 is a closed single-loop automatic control system (current control loop), and on the 1st locomotive 1 -o

closed two-loop current and speed control system.

When starting on the lead locomotive, the driver with knobs 5 and 8 through element 7) ee, speed controller 6 sends a signal to the minimum signal extracting unit 3. The driver sets the values of signals from current setters 5 and speeds 8 depending on the mass of the train and the specific conditions of coupling and control.

Comparison element 7 generates a signal for the mismatch between the set and true values of the speed of the locomotive, which is fed to the input of the speed controller 6, the latter automatically performs a signal proportional to the speed of movement. At the output of the block 3, the minimum signal is formed; the smallest value is formed from the two signals coming from the current setting unit 5 and the 6 speed controller | I) STI.

The output signal of the block 3 is fed to the input of the setter 4 intensity, which provides n ,. 1An increase in current to a predetermined value, which provides the required rate of increase in acceleration or deceleration. The signal from the output of the intensity driver 4 through the unit 10 nagals one of the inputs of the comparison element P. The signal from the current sensor 15 is supplied pa e) y () the input of element 11 cfr. not having a pedunter (.1 of locomotive 1 and, as the chap value of the current of the slave locomotive 2 via the shed mine, the matching unit 12 and the block 10 to one of the inputs of the comparison element 1 1 of the articulated (slave) locomogive 2,

Pa comparing elements II of each of co4, i.e. iieinij ix locomotives 1 and 2 compare the setpoint current with the corresponding values P1.31: On the other hand, the error signals are adjusted accordingly to the 16kV regulators, which automatically work out the proportional signals. 1 ny given the value of the currents of traction dvngate, tey articulated locomotives. The signals from the outputs of the current regulators 16 as control devices through the control units 18 are fed to the input of the thyristor I1) generators 17, which have a controlling effect on the corresponding traction motors 14. The effect of the motor on the traction motor 4 is accomplished by smoothly modifying the output of the TnpnjCTOpHoro converter 17, P) of movement speeds equal to or libuise (second value, automatic system, ieinin articulated locomotives) (you and 1 and 2 reduce the current engines seeking to delay an increase in speed in this case. In this case, the signal (the error at the input of the speed controller 6 is minimum. Unit 3 generates

the signal is proportional to the error signal and implements the mode of stabilization of the speed of movement by reducing the current of the traction motors.

The device is built in such a way that any locomotive can be both a master and a slave. In the absence of a signal at the input of the unit 10, which is connected to the output of the current setting device 5, locomotive locomotive, connected by an output to one of the inputs of the minimum signal selection unit, with another output of which is connected to the output of the current output motor of the traction motors, and the output. -.- input the setting unit of the intensity of the change in the current of the traction motors, another comparison element, one of whose inputs is connected to the output of the current sensor of the traction motors.
