Раскрытие изобретения Disclosure of invention
Генератор полупериода содержит трехфазную катушку индуктивности со сталью 1, нагрузку 2, тиристоры 3 и конденсаторы, причем конденсаторы, соединенные треугольником 4, подключены параллельно трехфазному источнику переменного тока, к которому, также параллельно, через тиристоры 3, подключены трехфазная катушка индуктивности со сталью 1, другие конденсаторы, соединенные треугольником 6, конденсаторы, соединенные в звезду 5, и нагрузка 2. The half-cycle generator contains a three-phase inductor with steel 1, a load 2, thyristors 3 and capacitors, and the capacitors connected by a triangle 4 are connected in parallel to a three-phase AC source, to which, also in parallel, through thyristors 3, a three-phase inductor with steel 1 is connected, other capacitors in delta 6, capacitors in star 5 and load 2.
Генератор полупериода работает следующим образом. Напряжение трехфазного источника переменного тока однополупериодно выпрямляется тиристорами 3 и подается на комбинированный колебательный конур, состоящий из соединенных параллельно между собой трехфазной катушки индуктивности со сталью 1 , конденсаторов, соединенных в звезду 5 и конденсаторов, соединенных треугольником 6. Протекающий по обмоткам катушки индуктивности 1 однополупериодный ток, индуцирует в них синусоидальную ЭДС, которая создает в колебательном контуре и нагрузке 2 синусоидальные токи. Конденсаторы, соединенные в звезду 5, составляют фазную, а конденсаторы, соединенные треугольником 6, линейную части комбинированного колебательного контура. Конденсаторы, соединенные треугольником 4, компенсируют реактивную мощность индуктивного характера. The half-cycle generator works as follows. The voltage of a three-phase AC source is half-wave rectified by thyristors 3 and fed to a combined oscillatory circuit consisting of a three-phase inductor with steel 1 connected in parallel to each other, capacitors connected in a star 5 and capacitors connected by a triangle 6. Half-wave current flowing through the windings of the inductor 1 , induces a sinusoidal EMF in them, which creates sinusoidal currents in the oscillatory circuit and the load 2. Capacitors connected in a star 5 make up the phase, and the capacitors connected by a triangle 6, the linear part of the combined oscillatory circuit. The capacitors connected by a triangle 4 compensate for the reactive power of an inductive nature.
На временных диаграммах, изображенных на фиг. 2, показаны напряжения и токи силовой части схемы. In the timing charts shown in FIG. 2, the voltages and currents of the power section of the circuit are shown.
