Description
Насто щее изобретение относитс к устройстиам д.1 измерени переменных напр жений, содержащим конденсатор, зар жаемый до амплитудного значени измер емого напр жени , и электронный иольтметр , измер ющий напр жение зар да конденсатора.The present invention relates to devices for measuring alternating voltages in 1, comprising a capacitor charged to an amplitude value of the measured voltage, and an electronic voltmeter measuring the voltage of the capacitor to be charged.
Предлагаемое устройство отличаетс от известных тем, что з устройстве применены два реле. Одно из них включено в цепь измер е .vioro напр жени и предназначено д, подключени конденсатора на зар д при каждом полупериоде ;1змер е.юго напр жени . Другое реле включено на то же измер емое напр жение, но обмотка его сдвинута па 90° по фазе. Это реле служит дл отключени зар женного ко}|денсатора после перехода измер емого напр жени через максимальное значение.The proposed device differs from the known ones in that two relays are used in the device. One of them is included in the measurement of the .vioro voltage and is designed to connect a capacitor to charge at each half-period; 1 dimension of its voltage. Another relay is connected to the same measured voltage, but its winding is shifted by 90 ° in phase. This relay serves to disconnect the charged co} | capacitor after the measured voltage passes through the maximum value.
Такое выполнение устройства дает возможность непрерывно измер ть амплитудные значени каждого периода нр.пр жени ипфранизкой частоты, что упрощает процесс измерени .Such an embodiment of the device makes it possible to continuously measure the amplitude values of each period of the reference voltage and the low frequency, which simplifies the measurement process.
Ма чертеже изображена принципиальна схе.ма предлагаемого устройства .Ma drawing shows a schematic diagram of the proposed device.
В устройстве применен обычный а.мплитудный вольтметр, содержащий запоминающее приспособление, выполненное в виде конденсатора С, зар жаемого до амплитудного значени измер емого напр жени , и электронный вольтметр с из.мерите.льным прибором А и входной лампой Л, к сетке которой подключен конденсатор С. Дл автоматического включени и отключени конденсатора в требуемые моменты времени использованы два реле PI и PZ, обмотки которых питаютс от источника измер емого напр жени : одна-непосредственно, а друга -со сдвигом в 90 по фазе.The device uses a conventional a. Voltmeter voltmeter containing a memory device made in the form of a capacitor C charged to the amplitude of the measured voltage, and an electronic voltmeter with measured meter A and an input lamp L with a capacitor C. For the automatic switching on and off of the capacitor at the required time points, two relays PI and PZ are used, the windings of which are powered from the source of the measured voltage: one directly, and the other with a shift of 90 in phase.
Контакты реле PI включают конденсато) С в цепь измер емого напр жени в момент, близкий к достижению им максимального значени , а контакты реле РЗ отключают конденсатор от цепи зар да после переThe contacts of the PI relay switch on the condensate C into the circuit of the measured voltage at a time close to reaching its maximum value, and the contacts of the relay of the relay disconnect the capacitor from the charge circuit after overpowering
