SU106211A1 - Relay distributor - Google Patents

Description

Automatics and telemechanics are widely used for differential distribution of power and pulses. These distributors can be made on the basis of the use of relay circuits, which contain a linear relay, switching relays and a system of self-blocking counting relays, operating in order of numbers, and switching their output circuits.

To simplify the electrical circuit of the relay pulse distributors and increase the reliability of their operation, this switching circuit is proposed, in which the counting relays take part twice in one cycle. First, the incoming pulses trigger the counting relays in the sequence 1C, 2C. . . . PC, then these relays in the same sequence are unblocked following P1, with their pulses.

FIG. 1 and 2 are schematic diagrams of the proposed distributor in two versions.

The separation of the electrical impulses entering the distributor into even and odd is done by the relay P separating the pulses. The operation of this relay is controlled by the linear relay L using the discharge capacitor C. In the initial position of the circuit, the capacitor C is charged, and when the relay is lowered, it is discharged to the winding / relay P, which triggers the relay. In the excited state, the relay P blocks itself through a winding.

At the end of the impulse, the relay L is energized and re-connects the capacitor C to charge. However, since this relay is held on self-blocking, capacitor C receives a charge of the opposite sign.

On the next pulse, the capacitor is ALWAYS connected to the winding / relay P, but now the capacitor discharge forces the relay to unlock (the first and second windings will act counter to). At the end of the second pulse, the circuit comes to its initial state in order to simplify the electrical circuit and increase the reliability of operation, the enable circuit of even and odd counting relays is connected through the above switches, and the contacts to even and, respectively, odd enable buses, switched by the relay contacts

separating the pulses in such a way that during the second half of the distributor cycle all countable returns returned to their initial position in the order of their numbers, for the second time participating in the operation of the circuit.
