Description

Насто щее изобретение относитс  к способам учета вли ни  токов утечек на результаты измерений больших сопротивлений одинарным мостом посредством измерени  сопротивлений утечек элементов мостовой схемы и внесени  поправок в результаты измерений.The present invention relates to methods for taking into account the influence of leakage currents on the measurement results of high resistances by a single bridge by measuring the leakage resistances of the elements of the bridge circuit and amending the measurement results.

Предлагаемый способ отличаетс  от известных тем, что сопротивлени  утечек измер ют у каждого из трех известных плеч моста в отдельности при собранной схеме моста.The proposed method differs from the known ones in that the leakage resistances are measured at each of the three known shoulders of the bridge separately with an assembled bridge circuit.

Такой способ дает возможность повысить точность измерений больших сопротивлений одинарным мостом.This method makes it possible to improve the accuracy of measurements of large resistances with a single bridge.

На чертеже изображена схема измерений сопротивлений при использовании предлагаемого способа.The drawing shows a diagram of measurements of resistance when using the proposed method.

Измерение производитс  одинарным мостом, составленным из неизвестного сопротивлени  / и трех известных сопротивлений Ry, и Величина сопротивлений утечек Г и гз определ етс  путем измерени  сопротивлени  утечки каждого из трех известных плеч , з и в отдельности в собранной схеме моста. Дл  этой цели в конструкции моста должны быть предусмотрены две перемычки дл  отключени  плеч моста при измерении их сопротивлений утечек.The measurement is made by a single bridge composed of an unknown resistance / and three known resistances Ry, and the magnitude of the leakage resistances G and r3 is determined by measuring the leakage resistance of each of the three known arms, h and separately in the assembled bridge scheme. For this purpose, two bridges should be provided in the bridge construction to disconnect the bridge arms when measuring their leakage resistance.

При измерении больших сопротивлений всегда должна быть включена перва  декада плеча сравнени  , максимальное значение плеча отношени  и соответствующее значение сопротивлени  в зависимости от диапазона измерений (т. е. Ю л, 100 ом и максимум ЮООо ).When measuring large resistances, the first decade of the reference arm, the maximum value of the ratio shoulder, and the corresponding value of the resistance should always be included depending on the measurement range (i.e., U l, 100 ohm, and maximum OOOO).

Сопротивление утечки плеча сравнени  в принципе должно зави сеть от положени  декадного переключател , но, как показывает опыт, при значении 2 1000 ом оно практически не зависит от положени  переключател ; поэтому можно определить его дл  любого положени  переключател . Также достаточно определить сопротивление утечкиThe leakage resistance of the comparison arm in principle should depend on the network position of the decade switch, but experience shows that with a value of 2 1000 ohms it practically does not depend on the position of the switch; therefore, it can be defined for any position of the switch. It is also sufficient to determine the leakage resistance.
