(54) RELAY DISTRIBUTOR

The invention is intended for use in automation, in particular, in telemechanics devices for power supply objects.

A relay solvent is known that contains n parallel cells with a polarized relay 1. It has large power consumption.

The closest to the invention according to the technical essence is a relay distributor, which has n parallel cells with a diode / capacitor, two-winding: polarized relays in each | Pike, the first winding of which is connected to a power source, and a switching contact 2.

This valve is quite simple, however, due to the fact that the capacitor charge current passes through the winding, hence the power consumed by the valve depends on the type of relay used in it. The purpose of the invention is to reduce power consumption.

This is achieved by the fact that in the relay distributor, containing two pairs of chains, connected between the power buses and consisting

From the series connected resistors with a torus and a key, as well as polarized relays in each channel, the point of connection of the resistor and key of the first chain is connected via a closing start button with the turn-on winding of the first polarized relay, and through a closing return button with a winding

The drums are connected to the switch-on terminals of switching on even polarized relays. In the drawing, an electrical schematic diagram of the relay distributor is shown. The distribution distributor contains resistors 1 and 2, switches 3 and 4, diodes 5-8, capacitors 9-12, polarized relays 13-15, start button 16 and return button 17, the initial state of the distributor corresponds to the diagram in the drawing. After the power is supplied and the control signals are issued, keys 3 and 4 need to be unlocked to start up; 16 until the relay, li, 11, is released (5 release the key and close the key 3 and open the key 4.
