The drawing shows a block diagram of a device for controlling the resistance of insulating joints,

The device for monitoring the resistance of insulating joints contains a signal generator 1, a signal receiver 2, an actuator 3, capacitors 4 and 5, connecting rails 6.1 and 6.2, 7.1 and 7.2 of each of the rail circuits 6 and 7f, insulating joints 8.1 and 8.2, key element 9 and a pulse generator 10. Moreover, the first output of the signal generator 1 is connected to the rail 6.1 of the rail circuit 6, and the adjacent rail 7.1 of the rail circuit 7 is connected to the first output terminal of the key element 9, the first output terminal

the element 9 is connected to the rail 6.2 of the rail circuit 6, and the adjacent rail 7.2 of the rail circuit 7 is connected to the first output terminal of the signal receiver 2, the second output terminal of which is connected to the second output terminal of the key element 9, the second output terminal of the signal generator 1 is connected to the second output of the input of the key element 9; the output of the pulse generator 10 is connected to the control input

key element 9 and with the synchronization input of the receiver 2 signals. An executive element 3 is connected to the output of the receiver 2 signals.

5 The proposed device operates as follows.

If the insulating joints 8.1 and 8.2 are in good condition, the frequency generated by the signal generator 1 through the rail

0 6.1, capacitor 4, rail 6.2 is fed to the input of key element 9. A controlled pulse generator 10, key element 9 generates pulses filled with the frequency of the signal of signal generator 1, which from its output through rail 7.1, capacitor 5, rail 7.2 go to the input a signal receiver 2 provided with a pulse signal selector (not shown). The presence of pulses filled with frequency

0

signals and 10 pulses synchronized by the generator 10, will cause a signal at the output of the receiver 2 to have a level sufficient to trigger the actuation element 3. When the insulating

of junction 8.1, a continuous signal from signal generator 1 through rail 6.1, insulating junction 8.1, rail 7.1, capacitor 5, rail 7.2 is constantly fed to the input of receiver 2 of the signals. At the entrance of an insulating joint

8.2 continuous1 signal from the signal generator 1 through rail 6.1, capacitor 4, rail 6.2, isolating junction 8.2, rail 7.2 is constantly supplied to the input of the receiver 2 signals,

.--.

This will lead to the disappearance of the voltage at the output of the receiver 2 signals, since a continuous signal of the frequency of the generator 1 of the signals cannot pass through

pulse signal selector of the receiver of 2 signals. The absence of a signal at the output of the signal receiver 2 is fixed by the actuating element 3. A similar situation occurs when both insulating joints meet.
