Claims (1)

Формула изобретенияClaim Устройство для пуска однофазного автоматического повторного включения линий электропередачи переменного тока, содержащее блок задержки и блок включения в цепи управления каждой фазой выключателя, отличающееся тем, что, с целью уменьшения качаний и ограничений перенапряжений, в него введены три логических элемента И, последовательно соединенные блок измерения заданной симметричной составляющей тока линии и блок сравнения измеренного значения с заданным, выход которого подключен ко вторым входам трех логических элементов И, первые входы каждого из которых соединены с соответствующим блоком задержки, а выходы подключены к соответствующим блокам включения.A device for starting a single-phase automatic reclosing of AC power lines, containing a delay unit and a switch-on unit in the control circuit of each phase of the switch, characterized in that, in order to reduce oscillations and overvoltage limitations, three AND logic elements are introduced into it a given symmetrical component of the line current and a unit for comparison of the measured value with the set one, the output of which is connected to the second inputs of three logical elements AND, the first I rows each of which is connected to the corresponding delay block and outputs connected to respective switching units.
