Description
Измерение мощности электрических потерь в металлических объектах, расноложеи«ых з зоне магнитных полей, создаваемых токонесущими проводами электрическо линии, обычно производитс методом двойных замеров или косвенными методами.The measurement of the power of electrical losses in metal objects, located in the zone of magnetic fields created by current-carrying wires of an electrical line, is usually made by the method of double measurements or by indirect methods.
Эти методы не обеспечивают лысокой чувствительности и необходимой точности замеров.These methods do not provide bald sensitivity and the required accuracy of measurements.
Предлагаемое устройство позвол ет производить измерение потерь с большей точиостью.The proposed device allows measurement of losses with greater accuracy.
На чертеже изображено предлагаелгое устройство дл измерени мощности электрических потерь в мета.тлических объектах.The drawing shows a proposed device for measuring the power of electrical losses in meta-technical objects.
Это устройство имеет трансформаторы 1, 2, 3 и 4 напр жени . Между траисформато)ами / и 2 иахслитс контролируемый объект 5. Первичиые обмотки 6 трансформаторов напр жени подключены между токоведуихими Ироводами в трех равиоотсто щих одна от другой точках линий. Вторичные обмотки 7 всех траисформаторов включены дифференииально с таким расчетом, чтобы при отсутствии объекта в зоне сети результирующее напр жение было нулю. Эти обмотки подключены к цепи напр жени заттмет-ра 8, токова обмотка которого питаетс от той же сет;: через тран:форматор тока .9.This device has 1, 2, 3 and 4 voltage transformers. Between the transport units / and 2 and the object under control 5. The primary windings of 6 voltage transformers are connected between current-carrying Irovodes in three points of the lines apart from each other. The secondary windings of all 7 transformers are enabled differentially so that in the absence of an object in the network zone, the resulting voltage is zero. These windings are connected to the voltage circuit of the terminal 8, the current winding of which is powered from the same set ;: via the current transformer .9.
Величина потерь отсчитываетс по ваттметру после введени контролируемого объекта в ЗОНУ магиитногэ пол сети.The magnitude of the loss is measured by the wattmeter after the controlled object is introduced into the ZONE of the magic network floor.
