Abstract

Изобретение относитс к измерительной технике и может быть использовано дл контрол пор дка чередовани Фаз трехфазной сети переменного тока. Цель изобретени - упрощение - достигаетс благодар тому, что в устройстве , содержапрм три формировател импульсов 1,2,3, входы которых соединены с трем входами 4,5,6 устройства , три элемента И 7,8,9, три элемента ИЛИ 1П,11,12, первый вход первого элемента И 7 соединен с выходом первого формиоовател импульсов 1, а выход - го орым входом первого элемента ИГО 1U, выход которого соединен со вторым входом первого элемента И 7, первый вход рторого элемента И 8 соединен с выходом третьего формировател импульсов 3, а выход - с первым входом второго элемента ИЛИ 11, второй вход которого соединен с выходом третьего элемента И 9, второй вход которого соединен с выходом второго элемента ИЛИ 11, три входа третьего элемента ИЛИ 12 соединены с выходами соответственно трех формирователей импульсов 1,2,3, а выход - с первым входом третьего элемента И 9, выход первого элемента И 7 соединен со вторым входом второго элемента И 8, а выход третьего элемента И соединен с выходом устройства. 1 ил. so tf СThe invention relates to a measurement technique and can be used to control the order of the alternation of the phases of a three-phase AC network. The purpose of the invention, a simplification, is achieved due to the fact that in the device, there are three pulse formers 1,2,3, the inputs of which are connected to three inputs 4,5,6 devices, three elements AND 7,8,9, three elements OR 1П, 11.12, the first input of the first element I 7 is connected to the output of the first pulse generator 1, and the output by the first input of the first IGO 1U element, the output of which is connected to the second input of the first element And 7, the first input of the third element And 8 is connected to the output of the third pulse driver 3, and the output - with the first input of the second element that OR 11, the second input of which is connected to the output of the third element AND 9, the second input of which is connected to the output of the second element OR 11, the three inputs of the third element OR 12 are connected to the outputs of three pulse formers 1,2,3, respectively, and the output to the first the input of the third element And 9, the output of the first element And 7 is connected to the second input of the second element And 8, and the output of the third element And is connected to the output of the device. 1 il. so tf С
