Description

 -. The invention relates to a pulse technique and can be used in switching devices of electrical circuits. The purpose of the invention is to simplify the device by reducing the number of elements (diodes and capacitors. In each of the cells. The drawing shows the basic electrical circuit of the proposed splitter. Relay distributor contains a power source with the first 1 and second 2 tires, capacitor 3, diode 4, control contact group 5, reset contact 6 and threshold element (Zener diode) 7, in each of the packs, a two-winding relay 8 with a switching contact group 9 and a thyristor 10. Termination contact of the contact group 9 p. eight This cell is connected to the switching contact of the contact group 9 of the relay 8 of the next cell. The first terminals of the switching windings 11 of the relay 8 are connected to the bus 2 and the closing contact of the control group of contacts 5 through the corresponding thyristors and connected through the capacitor 3 to bus 2, and through diode 4 to the switching contact of contact group 5, between which and the switching contact of the contact group of relay 8 of the first cell the stabilizer 7 is turned on.

532 Ristors 10 are connected with the break contact of the contact group 9 of the relay 8 of this cell. The first terminals of the switching windings 12 of the relay 8 are combined and connected via pin 6 to the supply bus 1, and the second terminals of the windings 12 are connected to the bus 2. The relay distributor operates as follows. In the initial state, the capacitor 3 is discharged, and the opening contacts of the contact group 9 of all relays 8 are closed. When the power is turned on, capacitor 3 is charged through diode 4, switching and disconnecting contacts of contact group 5. When switching switching contact of group-contacts 5 through thyristitron 7, the first cell thyristor 10 is switched on and capacitor 3 is discharged through switching thyristor 10 on winding 11 of relay 8 which is triggered, and the closing contact of the contact group 9 closes and prepares the circuit for switching on the next (second) cell. The stabilization voltage of the Zener diode 7 and the capacitance of the capacitor 3 are chosen so that when the switching contact of the control group of contacts 5 is switched once, the excitation of two relays 8 does not occur. When contact 6 is closed, the distributor is reset.
