Description

Насто щее изобретение относитс  к устройствам дл  измерении комплексных сопротивлений, выполненным по схеме неуравновешенного моста переменного тока, на входе и на выходе которого включены измерительные приборы: один - дл  контрол  напр жени  питани  моста, а другой - дл  непосредственного отсчета величины измер емого сопротивлени .The present invention relates to devices for measuring impedances made according to the unbalanced AC bridge scheme, at the input and output of which measuring instruments are included: one to monitor the supply voltage of the bridge, and the other to directly read the value of the measured resistance.

Предлагаемое устройство отличаетс  от известных устройств .подобного рода тем, что дл  определени  знака реактивной составл ющей измеренного сопротивлени  применено дополнительное чисто реактивное (емкостное) сопротивление. Это сопротивление включаетс  после измерени  В плечо моста последовательно с измер емым сопротивлением и позвол ет определить его знак по увеличению или уменьн1ению показаний ВЫХОДНОГО измерительного прибора.The proposed device differs from the known devices of a similar kind in that an additional purely reactive (capacitive) resistance is used to determine the sign of the reactive component of the measured resistance. This resistance is switched on after measuring the shoulder of the bridge in series with the resistance being measured and allows its sign to be determined by increasing or decreasing the readings of the OUT measuring instrument.

Такое выполнение устройства позвол ет упростить схему моста.Such an embodiment of the device simplifies the bridge circuit.

На чертеже изображена принципиальна  схема предлагаемого моста.The drawing shows a schematic diagram of the proposed bridge.

Измер емое сопротивление 1 включаетс  в одно из плеч моста, остальными плечами которого служат активное 2 и комплексные сопротивлени  3 и 4. Напр жение источника 5 неременного тока, питающего мост, контролируетс  с помощью измерительного прибора 6, подключенного Параллельно входной диагонали моста. На выходе моста включен второй измерительный прибор 7, по которому отсчитываетс  значение измер емого сопротивлени .Measured resistance 1 is included in one of the bridge arms, the remaining arms of which are active 2 and impedance 3 and 4. The voltage of the source 5 of a non-random current supplying the bridge is monitored using a measuring device 6 connected in parallel to the bridge diagonal input. At the output of the bridge, a second measuring device 7 is switched on, according to which the value of the measured resistance is measured.

Дл  определени  знака реактивной составл ющей измер емого сопротивлени  последовательно с ним с помощью кнопки 8 включаетс  дополнительное известное реактивное сопротивление, например конденсатор 9. В зависимости от того, увеличиваютс  или уменьщаютс  показани  прибора 7 на выходе моста при включении конденсатора 9, определ ют характер (знак) реактивной составл ющей измер емого сопротивлени .To determine the sign of the reactive component of the measured resistance in series with it, button 8 turns on an additional known reactance, such as capacitor 9. Depending on whether the readings of instrument 7 at the output of the bridge increase or decrease when the capacitor 9 is turned on, the character ( ) the reactive component of the measured resistance.
