Description
Согласно изобретению, предлагаетс пр мопоказывающий стрелочный детекторный частотомер с твердыми выпр мител ми и логометром в качестве индикатора дл контрол частот пор дка 50 га.According to the invention, a direct reading arrow detector frequency meter with solid rectifiers and a log meter is proposed as an indicator for monitoring frequencies of about 50 hectares.
Отличительной особенностью пред, лагаемого устройства, по сравнению с известными индикаторами частоты, вл етс то, что дл контрол посто нства частоты применено устройство , основанное на способе декомпенсации сбалансированной схемъ1 , причем декомпенсаци достигаетс изменением частоты измер емого тока.A distinctive feature of the device under consideration, in comparison with the known frequency indicators, is that a device based on the decompensation method of a balanced circuit-1 is used to control the frequency constant, and decompensation is achieved by varying the frequency of the measured current.
На чертеже дана схема измерител частоты, в котором логометр включен в фазочувствигельную схему , состо щую из двух выпр мительных мостиков, добавочных сопротивлений RI, и г и вторичных обмоток Гз входного трансформатора Т.The drawing is a diagram of a frequency meter in which the logometer is included in a phase-sensitive circuit consisting of two rectifying bridges, additional resistances RI, and r and secondary windings Gz of the input transformer T.
В качестве частотного контура предусмотрен резонансный контур из последовательно включенных элементов др, L и С, присоединенныхAs a frequency circuit provides a resonant circuit of the series-connected elements of others, L and C, connected
к обмотке 4 выходного трансформатора .to winding 4 output transformer.
Частотный контур св зан с измерительно-выпр мительным контуром при помощи сопротивлени г.The frequency circuit is connected to the measurement-rectifier circuit by means of resistance g.
При выбранной пол рности вторичных обмоток входного трансформатора , указанной на прилагаемом чертеже, в контуре / действует э.д.с. / -f- 5, а в контзфе //-э.д.с. Е ц EI - 5- Эти э.д.с. обуславливают соответствующие токи в paMiках логометра, который измер ет их отношение.At the selected polarity of the secondary windings of the input transformer indicated on the attached drawing, in the circuit / the emf is in effect. / -f- 5, and in contras // // ed.d.s. E C EI - 5- These emf. cause the corresponding currents in the paMiki of the gauge, which measures their ratio.
Как показали измерени , погрешности такого частотомера не превышали 0,05-0,1% гц.As the measurements showed, the errors of such a frequency meter did not exceed 0.05-0.1% Hz.
