Description

Предметом изобретени   вл етс  индукционное реле частоты, нредназиаченное дл  применени  в устройствах автоматической разгрузки энергосистем.The subject of the invention is an induction frequency relay, which is poorly designed for use in automatic unloading of power systems.

Примен юпдиес  дл  этих целей в насто щее врем  реле частоты имеют существенные недостатки (значительна  зависимость частоты срабатывани  от величины нодведенного нанр жени . неудовлетворительна  конструкци  контактной системы, HHSKUII коэффициент возврата , отсутствие тонкой регулировки контактов и т. п.).The use of devices for this purpose at the present time has a significant frequency relay (a significant dependence of the response frequency on the magnitude of the induced voltage. The unsatisfactory design of the contact system, HHSKUII return coefficient, lack of fine adjustment of contacts, etc.).

Описываемое реле частоты лишено большинства этих недостатков. Оно вынолнено на базе индукционного барабанного реле тина ИМБ-170. Схема реле нриведена на чертеже.The described frequency relay is devoid of most of these drawbacks. It is made on the basis of an induction drum relay of the IMB-170. Relay circuit is shown in the drawing.

Магнитопровод; реле дву.м  системами обмоток. Одна система состоит из двух катушек н 2 (см. чертеж), расноложениых на средних кернах ре.те и соединенных носледовате.пьно, друга -1из четырех катушек 5, 4, 5 и 6, расиоложенных на  рме. Последовательно с первой парой катушек включено регулируемое омическое сонротив ,(ер|ие 7, последовательно со второй ценью включен конденсатор 8. Потоки, создаваемые токами, текущими по этим обмоткам, сдвинуты на тол 90°.Magnetic core; Relay two meters winding systems. One system consists of two coils n 2 (see drawing), located on the middle cores of the river and connected nosledovat.no, the other -1 of the four coils 5, 4, 5 and 6, located on the frame. Adjustable ohmic radiation resistance is connected in series with the first pair of coils, (version 7, and a capacitor 8 are connected in series with the second value. The currents generated by the currents flowing through these windings are shifted by a thickness of 90 °.

Таким образом, в реле имеютс  две цени: одна RL и друга  LC.Thus, there are two values in the relay: one RL and another LC.

Параметры этих цеией нодобраиы та1ким образом, чтобы токи в них нри частоте равновеси  совпадали по фазе. При этом токи отстают от напр жени  на угол примерно 25-35°. При изменении частоты угол вектора тока в первой цепи (RL) измен етс  незначительно , во второй цени (LC) изменение частоты вызывает знач1ительное. изменение утла отставани  тока от напр жени . Уменьшение частоты вызывает поворот вектора тока в сторону опережени .The parameters of these tsiii are normally collected so that the currents in them at the equilibrium frequency coincide in phase. In this case, the currents lag behind the voltage by an angle of about 25-35 °. As the frequency changes, the angle of the current vector in the first circuit (RL) changes slightly, and in the second value (LC), the frequency change causes a significant one. change in the current lag from voltage. Decreasing the frequency causes the current vector to turn forward.

При совладении векторов тока обеих цепей момент на ре.те равен пулю. При расхождении векторов тока могмент определ етс  гфоекцией одного вектора на пернендикул р к другому, причем направление этой проекции может иметь положительное или отрицательное значеWhen the current vectors of both chains are co-owned, the moment on the river is equal to the bullet. If the current vectors diverge, the mogment is determined by the play of one vector perpendicular to another, and the direction of this projection can be positive or negative.
