в Комитет по дела.г изобретений и открытий при Совете Министров СССР Опубликовано в «Бюллетене изобретений Лс 5 за 1961 г.to the Committee on the case of inventions and discoveries at the Council of Ministers of the USSR Published in the “Bulletin of inventions Ls 5 for 1961

Изобретение относитс  к способам измерени  собственной емкости катушек индуктивности, осуществл емого посредством определени  резонанса на двух кратных частотах с последующим вычислением искомой е1мкости.The invention relates to methods for measuring the inherent capacitance of an inductor coil, carried out by determining the resonance at two times the frequency, and then calculating the desired capacitance.

Предложенный способ состоит в том, что дл  упрощени  процесса измерени  к катущке подвод тс  два переменных напр жени  высокой частоты, амплитуды которых отличаютс  между собой в такое же число раз, что и частоты, и по разности реактивных составл ющих токов в катущке определ ют величину собственной емкости катушки.The proposed method consists in that, to simplify the measurement process, two alternating high-frequency voltages are supplied to the coil, the amplitudes of which differ from each other by the same number of times as the frequencies, and the difference in the reactive components of the currents in the coil determine the magnitude of its own coil containers.

На чертеже изображена блок-схема прибора дл  осуществлени  предлагаемого сиособа.The drawing shows a block diagram of an apparatus for carrying out the proposed method.

Генератор высокой частоты Гвч имеет две фиксированные частоты MI и соо- К генератору подключено регулирующее сопротивление , с иомощью которого на испытуемой катушке L устанавливаетс  нужное напр жение UK, измер емое ламповым вольтметром ЛВ. Реактивные составл ющие токов /|, и /р катущки, измеренные при каждой из частот, определ ютс  по падению напр жени  на посто нном сопротивлении R-y. Фазочувствительный вольтметр ФЧВ измер ет только ту компоненту напр жени  f/K,, котора  пропорциональна реактивной составл ющей тока. Применение фазочувствительного вольтметра обусловливаетс  не только необходимостью измерени  реактивных токов /р и 1, но и тем, что фазы этих токов могут быть противоположны, что оказывает вли ние на алгебраическую разность:The high frequency generator GW has two fixed frequencies MI and a regulating resistance is connected to the generator, with the help of which the required voltage UK is measured on the test coil L, as measured by the LV lamp voltmeter. The reactive components of the currents /, and / p coils, measured at each of the frequencies, are determined by the voltage drop at a constant resistance R-y. The phase-sensitive voltmeter of the FCF measures only that component of the voltage f / K, which is proportional to the reactive component of the current. The use of a phase-sensitive voltmeter is caused not only by the need to measure reactive currents / p and 1, but also by the fact that the phases of these currents may be opposite, which affects the algebraic difference:

Зависимость Д/р от Со - собственной емкости катущки определ етс  выражением: А/р coi- Со (1 -«2), где: U и coi - напр жение и частота, имеющие некоторое определенное значение, an - некоторое целое число, показывающее во сколько раз отличаютс  напр жение и чаИНДУКТИВНОСТИThe dependence of D / p on Co, the coil's own capacity, is determined by the expression: A / p coiCo (1 - 2), where: U and coi are voltage and frequency having a certain specific value, an is an integer number indicating How many times the voltage and inductance are different

Предмет изобретени Subject invention

Способ измерени  собственной емкости катушек индуктивности с отсчетом на кратных фиксированных частотах, отличаюш,ийс  тем, что, с целью упрощени  процесса измерени , к катушке подвод т два переменных напр жени , амплитуды которых отличаютс  в то же число раз, что и частоты, а по разности реактивных составл ющих токов определ ют величину собственной емкости катушки.The method of measuring the inherent capacity of inductors with counting at multiple fixed frequencies is different because, in order to simplify the measurement process, two alternating voltages are applied to the coil, the amplitudes of which differ in the same number of times as the frequencies, and the differences of the reactive component currents determine the value of the coil's own capacitance.
