Изобретение относитс к области электротехники.This invention relates to the field of electrical engineering.
Известна лини электропередачи с расщепленными на п проводов фазами, в которой благодар расщеплению фаз достигаетс увеличение номинального тока ЛЭП и увеличиваетс ее пропт ск - на способность 1 .The known transmission line with phases split into p wires, in which, due to the splitting of the phases, an increase in the nominal current of the power transmission lines is achieved and its proptic speed increases to capacity 1.
В такой ЛЭП недостаточно используетс сечение проводов.In such power lines, the wire section is not sufficiently used.
Иэвестна также ЛЭП сверхвысокого напр жени с ращепленными на п проводов фазами Г23. Использование расщеплени фаз на ЛЭП сверхвысокого на пр жени обеспечивает передачу электрической мошрности на сверхдальние рассто ни . На работу такой ЛЭП существенное вли ние оказывает волновое сопротивление.Ievesta are also superhigh voltage power lines with G23 phases split on wires. The use of phase splitting on ultrahigh-voltage power lines to the yarn ensures the transmission of electrical moshrnosti to super-long distances. The work of such a transmission line is significantly affected by wave resistance.
В режимах, близких к холостому ходу (при нагрузке, меньшей натуральной мощности), в случае, когда на ЛЭП возникают перенапр жени , а проводимость короны, увеличиваетс , волновое сопротивление имеет неблагопри тную характеристику. Кроме того большое индуктивное сопротивление ЛЭП ограничивает их пропускную способность , ведет к. недостаточному использованию сечени провЬдов.In modes close to idle (with a load less than natural power), when overvoltages occur on power lines and the corona conductivity increases, the characteristic impedance has an unfavorable characteristic. In addition, the large inductive resistance of power lines limits their carrying capacity and leads to insufficient use of wire cross-sections.
Наиболее близкой к изобретению вл етс электропередача, содержаща ЛЭП с расщеплен ии на п проводов фазами и установку продольной компен10 сации с шунтирующим выключателем f3. Така электропередача увеличивает пропускную способность ЛЭП в расчете на каждый провод, однако установка продольной компенсации не улучшает харак15 теристику волнового сопротивлени в режимах меньше натуральной мощности.Closest to the invention is the power transmission, which contains power lines with a split on the p wire phases and the installation of longitudinal compensation with a shunt switch f3. Such transmission increases the transmission capacity of transmission lines per wire, however, the installation of longitudinal compensation does not improve the characteristic of wave resistance in modes less than the natural power.
Целью изобретени вл етс увеличение пропускной способности.The aim of the invention is to increase throughput.
