Description
Предметом изобретени вл етс трехфазный высоковольтный синхронный генератор, в котором кажда фаза обмотки статора состоит из нескольких частей, расположенных и соединенных между собой так, чтобы результирующие высших гармонических были уменьшены.The subject of the invention is a three-phase high-voltage synchronous generator, in which each phase of the stator winding consists of several parts arranged and interconnected so that the resulting higher harmonics are reduced.
На фиг. 1 и 2 иоказаны два различных варианта схем соединени обмоток генератора.FIG. 1 and 2, two different versions of the generator winding connection diagrams are shown.
Как видно из фиг. 1, фазна обмотка состоит из двух последовательно соединенных частей, из которых расположена на зубце, а втора - на рме. Указанному способу соединени обмоток ЛВС при наличии общей нулевой точки трех фаз соответствует диаграмма напр жений, в которой фазна э.д.с. представл ет собой геометрическую сумму двух э.д.с. взаимно сдвинутых (дл первой гармонической) на 30°. Коэффициент распределени такой обмотки дл первой гармонической , следовательно, равен „ cosAs can be seen from FIG. 1, the phase winding consists of two series-connected parts, of which is located on the tooth, and the second - on the rome. This method of connecting the windings of a LAN in the presence of a common zero point of the three phases corresponds to a voltage diagram in which the phase emf. is the geometric sum of two emf. mutually shifted (for the first harmonic) by 30 °. The distribution coefficient of such a winding for the first harmonic is therefore equal to
,965., 965.
Дл п той гармонической коэффициент распределени равен /С cosFor the fifth harmonic distribution coefficient is equal to / C cos
75° 0,258 и дл седьмой rapMoiHческой ,258.75 ° 0,258 and for the seventh rapMoiHical, 258.
Относительна величина результирующих п той и седьмой гармонических может быть еще более снижена прнменелием схемы, показанной на фиг. 2, где фазна обмотка состоит не из двух, а из четырех последователыю соединенных частей.The relative magnitude of the resulting fifth and seventh harmonics can be further reduced by the application of the circuit shown in FIG. 2, where the phase winding consists not of two, but of four consecutive connected parts.
