Abstract
Изобретение может быть использовано в однофазных цеп х переменного тока с большим уровнем помех и наличием высокоча стотных составл ющих и провалов. Цепь изобретени повышение помехоустойчивости. Мгновенные значени напр жени и тока с трансформаторов I и 2 тока и напр жени преобразуютс в код аналого- цифровыми преобразовател ми 10 и П. С помощью фильтра 8 и нуль-органа 3 формируетс сигнал, по которому в блоки 4 пам ти записываетс код, пропорциональный току при переходе напр жени через нуль. С помощью инвертора 9, умножител 12 частоты, счетчика 13 и дешифратора 14 формируетс сигнал, по которому в блоки 5 и 6 пам ти записьшаютс коды, пропорциональные току и напр жению при максимальном значении последнего.Вы- числнтельньй блок 7 по полученным с блоков 4,5 и 6 пам ти данным вычисл ет значени активной, реактивной и полной мощностей. 2 ил. с (ЛThe invention can be used in single phase AC circuits with a high level of interference and the presence of high frequency components and dips. The circuit of the invention increase noise immunity. The instantaneous values of voltage and current from transformers I and 2 of current and voltage are converted into code by analog-to-digital converters 10 and P. Using filter 8 and zero-organ 3, a signal is generated, according to which a code proportional to current at voltage over zero. Using an inverter 9, a frequency multiplier 12, a counter 13, and a decoder 14, a signal is generated, according to which codes 5 proportional to current and voltage are recorded in memory blocks 5 and 6 at the maximum value of the latter. Memory data 5 and 6 calculates active, reactive, and total power values. 2 Il. with (L
