Description

Насто щее изобретение относитс  к устройствам дл  компенсации зависимости показаний индукционного ваттметра от температуры.The present invention relates to devices for compensating the dependence of the indications of the induction power meter on temperature.

Предлагаемое устройство отличаетс  от известных тем, что в качестве компенсирующего элемента применен контур, состо щий из не завис щего от температуры активного сопротивлени , включенного последовательно с катущкой напр жени  ваттметра, и полупроводникового термосопротивлени , щунтирующего активное сопротивление и часть обмотки катушки напр жени .The proposed device differs from the known ones in that a circuit consisting of a temperature-independent resistance, connected in series with a wattmeter voltage coil, and a semiconductor thermal resistance, shunting the resistance and part of the voltage coil, is used as a compensating element.

Такое выполнение устройства обеспечивает повышение точности показаний ваттметра.This embodiment of the device provides improved accuracy of the wattmeter.

На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

Последовательно с катушкой напр жени  W „ ваттметра включают активное сопротивление R, величина которого не зависит от температуры, а параллельно ему и части катушки W „ включено полупроводниковое термосопротивление R т - отрицательным температурным коэффициентом .Consistently with the voltage coil W „of the wattmeter include active resistance R, the value of which does not depend on temperature, and parallel to it and part of the coil W„ the semiconductor thermal resistance R t is switched on - a negative temperature coefficient.

Подбором значений сопротивлений R, R т и числа витков AW (шунтируемой части катушки W) можно добитьс  полной компенсации температурной погрешности индукционного ваттметра.By selecting the resistance values R, R t and the number of turns AW (shunt part of the coil W), one can achieve complete compensation for the temperature error of the induction power meter.
