Изобретение относитс к электроизмерительной технике и может найти применение при бесконтактных измерени х больших посто нных токов.The invention relates to electrical measuring equipment and can be used in contactless measurements of high direct currents.
Известен преобразователь посто нного тока компенсационного типа, содержащий копенсационную обмотку, блок питани , усилитель в цепи компенсации, гальваномагнитный элемент и измерительный прибор.A DC-to-DC converter of the compensating type, comprising a compensating winding, a power supply unit, an amplifier in the compensation circuit, a galvanomagnetic element, and a measuring device.
Целью изобретени вл етс повышение точности измерений.The aim of the invention is to improve the measurement accuracy.
Дл этого гальваномагнитный элемент (например, преобразователь Холла или маг нитосопротивление ) помещен внутри компенсационной обмотки.For this, a galvanomagnetic element (for example, a Hall transducer or magnetoresistance) is placed inside the compensation winding.
На чертеже приведена схема преобразовател .The drawing shows a diagram of the Converter.
Он содержит компенсационную обмотку 1 внутри которой расположен гальваномагнитный элемент 2 (например преобразователь Холла или магнитосопротивление). Гальваномагнитный элемент питаетс от стабильного источника тока 3. Электроды гальваномагHiiTHoi o элемента 2 через усилитель 4 соединены с компенсационной обмоткой 1. В It contains a compensation winding 1 within which a galvanomagnetic element 2 is located (for example, a Hall transducer or magnetoresistance). The galvanomagnetic element is powered by a stable current source 3. The electrodes of the galvanic HiiTHoi o element 2 are connected via an amplifier 4 to the compensation winding 1. In
цепь компенсации включен измерительный прибор 5, проградуированный в единицах преобразуемого посто нного тока.The compensation circuit includes a measuring device 5, calibrated in units of convertible direct current.
Принцип работы преобразовател состоиг в следующем. После расположени преобразовател около токоведущей шины с посто нным током, последним создаетс маг-нитное поле, которое, воздейству на гальваномагнитный элемент 2, вызывает по вление на его выходе э. д. с. Эта э. д. с. после усилени усилителем 4 и подачи на компенсационную обмотку 1 создает, в евою очередь также магнитное поле Н , которое в местеThe principle of operation of the converter is as follows. After the converter is located near the busbar with direct current, the magnetic field is created last, which, acting on the galvanomagnetic element 2, causes the appearance of its output e. d. This uh. d. after being amplified by amplifier 4 and fed to the compensation winding 1, in turn also creates a magnetic field H, which is in place
-К-TO
расположени гальвавомагнитног-о элемента направлено встречно полю Нц . Э. д с. будет генерироватьс до тех пор, пока не произойдет сравнение по абсолютной веш1чипThe location of the galvanomagnetic element is directed oppositely to the field Hz. E. d. will be generated until the absolute vertical comparison is made
магнитных полей Н и Н . Величина иреобк иmagnetic fields H and H. Ireobk
