Description

Обычно при измерени х с фазами прибор должен иметь на выходе две электродвижущие силы, строго одинаковые по частоте к сдвинутые друг относительно друга по фазе, при чем при изменении частоты угол сдвига фаз доджей оставатьс посто нным. Единственный прибор , обладающий этими, свойствами,- машина Франка, кроме своей большой сложности и дороговидны имеет большой недостаток, заключающийс в том, что он работает в очень узком диапазоне частот 300-2000 с/сек.Usually, when measuring with phases, the device must have at its output two electromotive forces that are exactly the same in frequency as those shifted relative to each other in phase, and with a change in frequency the angle of phase shift of the Dodge remains constant. The only device possessing these properties, the Frank machine, besides its great complexity and expensive, has a great disadvantage in that it operates in a very narrow frequency range of 300-2000 s / s.

Предлагаетс устройство дл получени токов низкой частоты методом биений , с помощью которого может быть получено на выходе генератора низкой частоты напр жение любой частоты и фазы.A device is proposed for producing low-frequency currents by the beating method, with which a voltage of any frequency and phase can be obtained at the output of a low-frequency generator.

Согласно изобретению, дл получени двух электродвижущих сил одной и той же частоты, но с разными фазами, один из интерферирующих генераторов высокой частоты, св зан с вращателем фазы.According to the invention, to obtain two electromotive forces of the same frequency, but with different phases, one of the interfering high frequency generators is coupled to a phase rotator.

High frequency from quartz oscillator 5, also passed high frequency amplifier 6, having, like the first, double output, falls on the same two bridges, one directly, and the other through the circuit 7 (circled by a dotted line), rotating the high frequency phase. By then detecting the oscillations using two separate detectors 8, 9, two completely identical frequencies are obtained, but out of phase. The capacitance or resistance of the intermediate circuit 7 is obtained by changing the phase shift of the low frequency currents, which will be constant at all frequencies.
