Устройство дл  измерени  отиошени  двух электрическихA device for measuring the wake of two electrical

величинvalues

За влено 19 апрел  1941 года в Народный комиссариат электропромышленности СССР за № 42764 (306113)It was filed on April 19, 1941 with the People's Commissariat for the Electrical Industry of the USSR No. 42764 (306113).

Предметом изобретени   вл етс  устройство дл  измерени  отноше ,ни  двух электрических величин, в частности, напр жений.The subject of the invention is a device for measuring the ratio of two electrical quantities, in particular, voltages.

Дл  измерени  отношени  сравниваемых напр жений, согласно изобретению , применены два потенциометра , подвижные контакты которых механически св заны между собой. Один контакт включен через нулевой прибор или реле навстречу неизменному напр жению, а другой подключен к измерительному прибору .Two potentiometers are used to measure the ratio of the compared stresses according to the invention, the moving contacts of which are mechanically interconnected. One contact is connected via a zero device or a relay towards a constant voltage, and the other is connected to a measuring device.

На чертеже приведена схема предлагаемого устройства, где t/i и t/2 - сравниваемые напр жени , Ri и Ri - потенциометры, Д) и Д2 - подвижные контакты потенциометров , НП - нулевой прибор, ИП - измерительный прибор.The drawing shows the scheme of the proposed device, where t / i and t / 2 are the compared voltages, Ri and Ri are potentiometers, D) and D2 are movable contacts of potentiometers, NP is a zero device, PI is a measuring device.

Передвига  контакты потенциометров до тех пор, пока нулевой прибор ни не устаноБ1Итс  на нуль, ПО прибору ИП отсчитывают величину измер емого отношени .Moving the potentiometer contacts until the zero instrument is set to zero, the PI instrument counts the value of the measured ratio.

Если напр жени  f/i и t/2 измен ютс  во времени с заметной скоростью , то дл  автоматическойIf the voltages f / i and t / 2 change with time at a noticeable speed, then for automatic

остановки обоих подвижных контактов в момент установки НП на нуль (т. е. при осуш;ествлении компенсации ) на потенциометре i предусмотрено перемешение подвижных контактов потенциометров электродвигателем, включенным через нулевой прибор.stopping of both moving contacts at the time of the NP setting to zero (i.e., when drying; compensation) the potentiometer i provides for the moving of the moving contacts of the potentiometers by an electric motor connected via a zero device.

Вместо нулевого индикатора и источника вспомогательного напр жени  /о можно применить реле, размыкаюш;ее цепь измерительного прибора при достижении компенсации на потенциометре Ri, т. е. в момент установки НП на нуль.Instead of the zero indicator and auxiliary voltage source / o, a relay can be used, it opens, its measuring circuit when compensation is reached at the potentiometer Ri, i.e. at the time of the NP setting to zero.
