Изобретение относитс к преобразовательной технике и может найти применение при построении компенсационных установок.The invention relates to converter equipment and may find application in the construction of compensatory installations.
Известна схема включени источников реактивной мощности в четырехпроводную сеть переменного тока, содержаща конденсатор, параллельно которому через включенные встречно-параллельно управл емые вентили подсоединена катушка индуктивности, причем указанна последовательна цепь в виде треугольника подключена к четырехпроводной сети (11/A known circuit for switching reactive power sources into a four-wire AC network contains a capacitor, in parallel with which an inductance coil is connected through connected anti-parallel controlled valves, with the indicated triangle series connected to a four-wire network (11 /
Недостатками данной схемы включени вл ютс высокий коэффициент нелинейных искажений, вносимых в кривую напр жени сети при большой глубине регулировани , больша установленна мощность катушки индуктивности, равна номинальной мощности источника, необходимость применени управл емых вентилей на полный рабочий ток из-за установки их непосредственно в снловой цепи катушки индуктивности.The disadvantages of this switching circuit are the high non-linear distortion coefficient introduced into the network voltage curve with a large depth of regulation, the greater the installed inductance power, is equal to the rated power of the source, the need to use controlled gates for the full operating current inductor circuit.
Наиболее близкой к предлагаемому техническому решению вл етс схема включени однофазных источников реактивной мощности, содержаща соединенные в треугольник три однофазных источника реактивной мощности, каждый из которых включает трансформатор с обмотками, две одноименные из которых расположены на крайних стержн х магнито; провода, соединены последовательно и согласно и подключены через конденсатор к выводам питающей сети, и управл ющую обмотку, расположенную на центральном стержне маг10 нитопровода соединенную последовательно & снмметричным тиристором, выводы обмотки управлени подключены к питающей сети, а вывод симметричного тиристора подключен к точке соединени выводов обмоток, распоts ложенных на крайних стержн х магнитопровода 2.Closest to the proposed technical solution is a circuit for switching on single-phase sources of reactive power, containing in triangle three single-phase sources of reactive power, each of which includes a transformer with windings, two of which are located on the extreme rods of the magneto; the wires are connected in series and according to and connected through a capacitor to the terminals of the power supply network, and a control winding located on the central rod of the mag10 thread connected in series & An unloaded thyristor, the control winding leads are connected to the mains, and the symmetric thyristor lead is connected to the connection point of the winding leads located on the extreme rods of the magnetic circuit 2.
Известна схема включени источников реактивной мощности к четырехпроводной сети характеризуетс наличием высщих гармоник The known scheme of switching sources of reactive power to a four-wire network is characterized by the presence of high harmonics.
