Description

The invention relates to electrical engineering and can be used to measure various electrical signals.

The purpose of the invention is to increase the speed and increase the reliability of the device :.

The drawing shows the proposed device.

The device includes 1-3 input and 4-6 output buses, switches 7-9 into three positions, the purpose of which is to provide one out of three closed contacts at its output, and the closure of the switch contacts occurs strictly alternately at times the arrival of a positive differential pulse at its input. Switches, for example, can be made to install them in a certain initial state, in our case this state corresponds to the closure of the first contacts. The closing contacts can be used as reed switch contacts, electronic switch switches, trigger 10, the counting input of which is connected to the bus 11 clock pulses 5 with input 12 of the first switch 7, and outputs with inputs 13 and 14 of the second 8 and third switch 9 .

When the supply voltage is applied, the switches 7-9 are reset, in which their first contacts 7-1 8-1, 9-15 are closed and the trigger 10 is reset, in which its right output is low. potential, and on the left high, by known means (not shown).

In the initial state, contacts 7-1, 8-1, 9-1 are closed and bus 1 is connected to bus 4.2 - from 5 ,. 3 - from 6.

At the time of the occurrence of a positive voltage drop on bus 11, the first switch 7 is activated, and therefore contact 7-1 is opened, and contact 7-2 is closed, trigger 10 is triggered and a positive voltage difference appears at input 13 triggers the second switch. S, in connection with which the contact 8-1 is opened and the contact 8-2 is closed.

Thus, bus 1 is connected to bus 5, bus 2 bus 4, bus 3 bus 6.

F

At the time of the appearance of the second differential voltage of positive polarity, the trigger 10 returns to its original state, and the first 7 and third 9 switches operate, while bus 1 is connected to bus 6, bus 2, bus 4, bus 3 bus 5.

After the third drop, bus 1 is connected to bus 4, bus 2, bus 6, bus 3, bus 5.

After the fourth differential, bus 1 is connected to bus 5, bus 2 bus 6, bus 3 bus 4.

After the first fall, tire 1 is unoedin bus 6, bus 2 bus 5, bus 3 bus 4.

In the event of a voltage drop, a three-tire bulkhead will return to the initial state, i.e. , 1-4, 2-5, 3-6.

Thus, for the neck of the voltage drops on the bus 11, the UT provides all possible combinations of three tires.
