Description
Предлагаемое устройство отнсзситс к аппаратам дл исследовани магнитных свойств железа.The proposed device relates to apparatus for studying the magnetic properties of iron.
В известных устройствах подобного типа измерение производитс по компенсационному методу. Дл это-i цели испытываемый образец железа, выполненный в виде замкнутого кольцевого сердечника с двум обмотками, намагничиваетс при помощи переменного тока известной силы, пропускаемого по одной из обмоток. Индуктируема при этом ВО вторичной обмотке электрОдвижуи;а сила компенсируетс при помощи подаваемого на ту же обмотку внешнего напр жени той же частоты, которое дл этого соответствующим образом сдвигаетс по фазе при помощи какого-либо фазовращающего устройства .In known devices of this type, measurement is carried out according to a compensation method. For this purpose, an iron test specimen, made in the form of a closed ring core with two windings, is magnetized by means of an alternating current of known strength, passed through one of the windings. In this case, the electromotive is induced in the secondary winding, and the force is compensated by the external voltage of the same frequency applied to the same winding, which is appropriately phase-shifted for this purpose with the help of some phase shifting device.
Во многих случа х практики вл етс желательным получение измер емых величин, как, например, ваттной и безваттной составл ющих намагничивающих ампервитков, в виде непосредственного отсчета этих величин на включённых в схему измерительных приборах .In many cases of practice, it is desirable to obtain measurable quantities, such as the watt and wattless components of the magnetized amperages, in the form of a direct reading of these quantities on the measuring instruments included in the circuit.
