Abstract
Изобретение относитс к электротехнике и может быть использовано в электроустановках , в которых необходим определенный пор док чередовани фаз трехфазной сети переменного тока. Цель изобретени - исключение самопроизвольного срабатывани устройства после устранени аварийного режима сети. Срабатывание устройства возможно только после замыкани управл емого ключа 13, в результате чего импульсе выхода формировател 3 импульсов поступает на второй вход элемента ИЛИ 8. При по влении импульса на выходе формировател 1 импульсов по вл етс импульс на выходе элемента И 4, обеспечивающий по вление импульсов на выходах элементов И 5-7, поступающих на входы элемента ИЛИ 12, на выходе которого формируетс сигнал логической единицы , соответствующий срабатыванию устройства. 3 ил.The invention relates to electrical engineering and can be used in electrical installations that require a certain order of phase alternation of a three-phase AC network. The purpose of the invention is the elimination of spontaneous operation of the device after eliminating the emergency mode of the network. The operation of the device is possible only after closing the controlled key 13, as a result of which the output pulse of the driver 3 of the pulses arrives at the second input of the element OR 8. When a pulse appears at the output of the driver of the pulse 1, a pulse appears at the output of the element 4, which ensures the appearance of pulses at the outputs of the elements And 5-7, arriving at the inputs of the element OR 12, at the output of which a signal of the logical unit is formed, corresponding to the operation of the device. 3 il.
