1. Способ определения температуры в электролизере для получения алюминия, включающий измерение напряжения на электролизере, отличающийся тем, что периодически определяют среднюю по мощности частоту колебаний напряжения в диапазоне частот 0,8-4,0 Гц и определяют температуру по формуле1. The method of determining the temperature in the electrolytic cell for producing aluminum, including measuring the voltage on the electrolyzer, characterized in that periodically determine the average power frequency of the voltage fluctuations in the frequency range of 0.8-4.0 Hz and determine the temperature by the formula T°(i)=T°(i-1)+К*(fcp(i)-fcp(ном)),T ° (i) = T ° (i-1) + K * (fcp (i) -fcp (nom)), где К - коэффициент пропорциональности, выбираемый из диапазона 5-60°

/ Hz;
fcp(i) - средняя по мощности частота колебаний напряжения;fcp (i) - average power frequency of voltage fluctuations; fcp(ном) - номинальное значение средней частоты колебаний напряжения, соответствующее номинальной температуре электролизера;fcp (nom) - nominal value of the average frequency of voltage fluctuations, corresponding to the nominal temperature of the cell; (i), (i-1) - текущий и предыдущий периоды определения температуры.(i), (i-1) - current and previous periods of temperature determination.
2. Способ по п.1, отличающийся тем, что измеряемое напряжение фильтруют двумя цифровыми полосовыми фильтрами, резонансные частоты которых настраиваются на нижнюю и верхнюю половины частотного спектра так, чтобы мощности на выходе фильтров оказались одинаковыми, при этом среднюю по мощности частоту колебаний напряжения определяют как среднее арифметическое из резонансных частот настройки обоих фильтров.2. The method according to claim 1, characterized in that the measured voltage is filtered by two digital band-pass filters, the resonant frequencies of which are tuned to the lower and upper halves of the frequency spectrum so that the output powers of the filters are the same, and the average power frequency of the voltage fluctuations is determined as the arithmetic mean of the resonant frequencies settings of both filters.
