Description
костными, в зависимости от расположени и транспозиции фаз.bone, depending on the location and transposition of the phases.
Устройство обеспечивает компенсацию реактивной составл ющей остаточного тока заземл ющей дуги, отключенной фазы во врем 1паузы однофазного автоматического повторного включени (ОАПВ), обусловлепную поперечными проводимост ми фаз на землю, и между фазами дл реальной несимметричной трехфазной линии с произвольным расположением проводов, при этом оно содержит 6 элементов.The device compensates for the reactive component of the residual current of the grounding arc, the disconnected phase during the single-phase auto-reclosing phase 1 (OAPO) caused by the transverse conductance of the phases to the ground, and between the phases for a real asymmetrical three-phase line with an arbitrary wire arrangement, and it contains 6 items.

Дл более точной компенсации остаточного тока с учетом вли ни распределенных емкостей вдоль линии, случайНых неодпородностей вдоль линии (лес, овраги, соседние линии и другие сопредметы) следует рекомендовать экспериментальную подстройку из параметров .In order to more accurately compensate for the residual current, taking into account the effect of distributed capacitors along the line, occasional heterogeneities along the line (forest, ravines, neighboring lines and other sub-objects), an experimental adjustment of the parameters should be recommended.
Использование описанного компенсирующего устройства обеспечивает практически полную Компенсацию остаточного тока заземл ющей дуги, отключепной фазы во врем паузы ОАПВ, при любой степени несимметрии линии. Это дает возможпость широко применить ОАПВ па лини х высщих классов напр жени , где это особенно важно дл повыщепи надежности и бесперебойности энергоснабжепи , улучшени качества электроэнергии , повышепи устойчивости параллельной работы, экономии резервов, снижени перенапр жений и улучшени технико-экономических показателей энергосистем.The use of the compensating device described above provides almost complete Compensation of the residual current of the grounding arc, the disconnected phase during the pause of the PELV, with any degree of line unbalance. This makes it possible to widely apply high-voltage power supply to high-voltage power lines, where it is especially important for increasing reliability and uninterrupted power supply, improving power quality, improving parallel operation stability, saving reserves, reducing overvoltages and improving power-economic performance.
