Description
Измерение электрической энергии разр да затруднено необходиMOCTbio одновременного осциллографированп тока и напр жени , а также последуюнхи.х трудоемких ои рациГк св занных с обработкой осциллограмм.Measuring the electrical energy of a discharge is difficult due to the MOCTbio simultaneous oscillographic current and voltage, as well as the subsequent laborious scans associated with processing oscillograms.
Предлагаемый нрибор позвол ет осуществл ть пр мое измерение энергии электрического за счет электрического перемножени мгновенных величин тока и напр жении.The proposed apparatus allows direct measurement of the energy of electrical energy by electrically multiplying the instantaneous values of current and voltage.
Принцип действи прибора аналг.гнчен принципу действи супергетеродинного приемника. Два гетеродина (коротковолновые или ультракоротковолновые генераторы) создают колебани , частоты которых отличаютс на посто нную величину, равную частоте промежуточного усилител . Балансные cxeMi i обеспечивают 100%-ную модул цию амплитуд колебаний обеих несущих частот сигналами, пропорциональными току и напр жению разр да. Смеситель, на сетки которого поступают оба модулированных колебани , выдел ет произведение их амплитуд на промежуточной частоте.The principle of operation of the device is similar to that of the superheterodyne receiver. Two local oscillators (shortwave or ultrashortwave oscillators) create oscillations whose frequencies differ by a constant amount equal to the frequency of the intermediate amplifier. The balanced cxeMi i provide 100% modulation of the amplitudes of oscillations of both carrier frequencies by signals proportional to the current and the discharge voltage. The mixer, on the grids of which both modulated oscillations are applied, selects the product of their amplitudes at an intermediate frequency.
Сигнал промежуточной частоты, пропорциональный мощности, усиливаетс , выпр мл етс и зар жает конденсатор. Величина зар да конденсатора при этом будет пропорциональна выделивщейс энергии электрического разр да. Напр жение на конденсаторе воздействует на сетку э; ектронной ламиы, изменение анодного тока которой регулируетс при помощи стрелочного прибора посто нного тока.The intermediate frequency signal, proportional to the power, is amplified, rectified and the capacitor is charged. The magnitude of the charge of the capacitor in this case will be proportional to the released energy of the electric discharge. The voltage across the capacitor affects the grid e; an electron lamia, the change in the anode current of which is regulated by means of a switch instrument of direct current.
Шкала стрелочного прибора может быть отградуирована в единицах энергии.The dial gauge can be calibrated in units of energy.
