Description
Точное измерение напр жен ш повышенной и высокой частоты в насто щее врем нроизводитс главным образом с помощью термоэлектрических компараторов, в которых сравниваетс тепловое действие измер емого тока с тепловым действием посто нного тока.Accurate measurement of high and high frequency voltages is now produced mainly by thermoelectric comparators, in which the thermal effect of the measured current is compared with the thermal effect of direct current.
При этом не учитываетс так называемый эффект Пельтье, добавочные потери от вихревых токов и от скин-эффекта, а также токи емкостных утечек. Автоматизаци процесса уравновешивани так же довольно затруднительна.It does not take into account the so-called Peltier effect, the additional losses due to eddy currents and the skin effect, as well as capacitive leakage currents. Automating the balancing process is also quite difficult.
Дл устранени этих недостатков предложено выполн ть подобные компараторы в виде дифференциальных электростатических приборов, в которых вращающий момент, создаваемый измер емым переменным током, приложенным между корпусом и одним подвижным электродом , компенсируетс проти;водействуюп1 ,им моментом, создаваемым посто нным током, приложенным между корпусом и другим подвижным электродом.To eliminate these drawbacks, it is proposed to perform such comparators in the form of differential electrostatic devices, in which the torque generated by the measured alternating current applied between the housing and one moving electrode is compensated for by the action of the direct current applied between the housing and another movable electrode.
Целью насто щего изобретени вл етс повышение точности измерений дифференциальных электростатических компараторов пзтем устранени погрешностей, обусловленных зтечками переменного и посто нного тока через емкость и изол цию между неподвижными электродами.The purpose of the present invention is to improve the measurement accuracy of differential electrostatic comparators in order to eliminate errors caused by alternating and direct current detectors through the capacitance and insulation between fixed electrodes.
Дл этого предлагаетс промежутки между подвижным электродом и неподвижными электродами, на которые подаютс переменное и посто нное напр жени , шунтировать соответственно емкостью п омическим сопротивлением.For this purpose, gaps between the movable electrode and the fixed electrodes, to which alternating and constant voltages are applied, are proposed to be shunted in accordance with a capacitance of an impedance.
На чертел е изображена принципиальна схема предлагаемого компаратора .The schematic diagram shows the schematic of the proposed comparator.
Компаратор представл ет собой дифференциальный электростатический прибор с подвижным электродом / и двум неподвижными электродами 2 и 3. Между электродами / и 2 подаетс измер емое переменное напр жение, а между электродами 1 и 3-Посто нное напр жение, создающее противодействующий мо-, мент.The comparator is a differential electrostatic device with a moving electrode / and two fixed electrodes 2 and 3. A measured alternating voltage is applied between the electrodes / and 2, and between the electrodes 1 and 3 is a countervailing momentum.
