ЧТО ОЗНАЧАЕТ СЛОВО THREE-PHASE
Трехфазный
В электротехнике трехфазные системы электропитания имеют по меньшей мере три проводника, несущих напряжения переменного тока, которые смещены во времени на одну треть периода. Трехфазная система может быть расположена в треугольнике или звезде. Система затвора позволяет использовать два разных напряжения из всех трех фаз, таких как система 230/400 В, которая обеспечивает 230 В между нейтральной и любой из фаз и 400 В на любых двух фазах. Устройство с треугольной системой обеспечивает только одно значение напряжения, однако оно имеет большую избыточность, так как оно может продолжать нормально работать с одной из трех обмотки питания в автономном режиме, хотя и на 57,7% от общей емкости. Гармонические токи в нейтрали могут стать очень большими, если подключены нелинейные нагрузки.
Значение слова three-phase в словаре английский языка
Определение трехфазного словаря состоит в наличии, генерации или использовании трех переменных напряжений одной и той же частоты, смещенных по фазе на 120 °.
