Abstract
Устройство симметрирования напряжений трехфазной сети, отличающееся тем, что не содержит коммутационных аппаратов и иных элементов, кроме индуктивных, и компенсирует несимметрию напряжений величиной до 100% за счет геометрического вычитания выделенного напряжения нулевой последовательности из напряжений всех трех фаз, для чего три группы последовательно соединенных вторичных обмоток трех понижающих однофазных четырехобмоточных трансформаторов с коэффициентом трансформации, равным трем, последовательно включаются каждая в провод соответствующей фазы так, чтобы происходило геометрическое вычитание выделенного на группах последовательно соединенных указанных вторичных обмоток напряжения нулевой последовательности из напряжений соответствующих фаз, а первичные обмотки данных трансформаторов соединяются в звезду и подключаются на фазное напряжение.A device for balancing the voltages of a three-phase network, characterized in that it does not contain switching devices and other elements other than inductive, and compensates for the asymmetry of voltages up to 100% due to the geometric subtraction of the selected zero-sequence voltage from the voltages of all three phases, for which three groups of series-connected secondary windings of three step-down single-phase four-winding transformers with a transformation coefficient of three are each connected in series to the wire with Resp phase so that subtraction occurred geometric allocated to groups of serially connected secondary windings of said zero sequence voltage of the respective phase voltages, and the transformer primary windings are connected in star data and connected to the phase voltage.
