Description
Сумма токов в тросах 4 и 5 и дополнительном проводе 6, когда фазы расположены в виде треугольника и дополнительно подвешен только один провод, должна быть равна нулю , что обеспечиваетс выполнением услови The sum of the currents in the cables 4 and 5 and the additional wire 6, when the phases are arranged in the form of a triangle and only one wire is additionally suspended, must be zero, which is ensured by the fulfillment of the condition

где Zl, 22, 2з - волновые сопротивлени фаз. В случае, когда фазы расположены горизонтально и дополнительно подвешено два провода, а напр жени на фазах линии образуют симметричную систему и отличаютс взаимно на 120°, получаютwhere Zl, 22, 2h are the wave impedances of the phases. In the case when the phases are arranged horizontally and two wires are additionally suspended, and the voltages on the phases of the line form a symmetrical system and differ mutually by 120 °, they obtain

Таким образом, присоединение тросов к дополнительно подвешенным проводам (или проводу) обеспечивает уменьшение продольной э. д. с., возникаюш,ей на грозозашитных тросах и наводимой за счет тока нагрузки в средней фазе, не менее чем в 5 раз, снижение напр женности пол на поверхности тросов на 70-80%, а также уровн радиопомех на 10-15 дб. Кроме того, такое выполнение линии улучшает экранирование средней фазы и позвол ет организовать канал св зи присоедипением аппаратуры уплотнени к средней фазе линии.Thus, the attachment of cables to additionally suspended wires (or wire) provides a reduction in longitudinal e. d. p., arising, at least 5 times on thunder-resistant cables and induced due to the load current in the middle phase, reduction of the floor tension on the surface of the cables by 70-80%, as well as radio interference level by 10-15 dB . In addition, this implementation of the line improves the shielding of the middle phase and allows the communication channel to be organized by connecting the compaction equipment to the middle phase of the line.
