star-delta starting
the process of starting a three-phase motor by connecting it to the supply with the primary winding initially connected in star, then reconnected in delta for the running condition

Параллельные тексты EN-RU Star-delta Y/Δ starting
Star-delta starting is the best known system and perhaps the commonest starting system at reduced voltage; it is used to start the motor reducing the mechanical stresses and limiting the current values during starting; on the other hand, it makes available a reduced inrush torque.This system can be used for motors with terminal box with 6 terminals and double supply voltage.
It is particularly suitable for no-load starting or with low and constant load torque or lightly increasing load torque, such as in the case of fans or low power centrifugal pumps.
Making reference to the diagram of Figure 6, the starting modality foresees the initial phase with star-connection of the windings to be realized through the closing of the circuit-breaker, of the line contactor KL and of the star contactor KY.
After a suitable predetermined period of time, the opening of the contactor KY and the closing of KΔ allow switching to delta-connection, which is also the configuration of normal running position.
[ABB]Пуск переключением со звезды на треугольник
Пуск переключением со звезды на треугольник является самым известным способом и, возможно, самой распространенной схемой пуска на пониженном напряжении. С одной стороны, этот способ используется для снижения механических нагрузок и ограничения пускового тока, а с другой - обеспечивает уменьшение пускового момента.Такая возможность может быть реализована в двигателях с шестью зажимами в выводной коробке, что позволяет питать его от двух напряжений.
Особенно этот способ подходит для ненагруженного пуска и пуска с низким постоянным или немного увеличивающимся вращающим моментом, например, для пуска вентиляторов или маломощных центробежных насосов.
Схема пуска переключением со звезды на треугольник представлена на рисунке 6. В начальный момент пуска обмотки статора соединяют звездой путем замыкания контактов автоматического выключателя, линейного контактора KL и контактора KY со схемой "звезда".
По истечении заданного времени контакты контактора KY размыкаются и замыкаются контакты контактора КΔ со схемой треугольник.
В результате выполняется переключение обмоток статора со схемы «звезда» на схему «треугольник».
Обе схемы соединения обмоток являются схемами нормального рабочего режима.
