Description

Предлагаемое устройство дл  измерени  частоты переменного тока относитс  к известному типу устройств того же целевого назначени , имеющих два датчика Холла, помещенных в воздушном зазоре электромагнита , обмотка которого питаетс  переменным током контролируемой сети.The proposed AC frequency measuring device is of a known type of devices of the same purpose, having two Hall sensors placed in an air gap of an electromagnet, the winding of which is powered by an alternating current of a monitored network.

В предлагаемом устройстве, подобно известным устройствам, токовые цепи датчиков питаютс  переменными токами, величина одного из которых не зависит от изменени  частоты переменного тока, а другого- мен етс  в зависимости от частоты.In the proposed device, like the known devices, the sensor current circuits are powered by alternating currents, the value of one of which does not depend on the change in the frequency of the alternating current, and the other varies depending on the frequency.

Особенности устройства, составл ющего предмет изобретени , заключаютс  в том, что токова  цепь одного из датчиков Холла включена в контролируемую сеть последовательно с обмоткой электромагнита и регулируемым активным сопротивлением, токова  цепь второго датчика подключена к дополнительной вторичной обмотке электромагнита, а измерительные цепи этих датчиков присоединены соответственно к обмоткам электрического логометра.The features of the device constituting the subject matter are that the current circuit of one of the Hall sensors is connected to the controlled network in series with the electromagnet winding and adjustable resistance, the second sensor current circuit is connected to the secondary coil of the electromagnet, and the measuring circuits of these sensors are connected respectively to the windings of the electric logometer.

Такое выполнение устройства обеспечивает возможность повьшени  точности измерени  частоты по сравнению с известными устройствами того же типа.This embodiment of the device provides the possibility of increasing the accuracy of frequency measurement in comparison with the known devices of the same type.

На чертеже представлена принципиальна  схема предлагаемогоThe drawing is a schematic diagram of the proposed

устройства.devices.

Как видно из чертежа, в воздушном зазоре электромагнита Л1 обмотка JK питаетс  переменным током контролируемой сети, где помещены два датчика Холла 1 и 2.As can be seen from the drawing, in the air gap of the electromagnet L1, winding JK is powered by an alternating current of the controlled network, where two Hall sensors 1 and 2 are placed.

Токова  цепь датчика Холла / включена в контролируемую сеть последовательно с обмоткой 1К электромагнита и регулируемым активным сопротивлением. На сердечник электромагнита М наложена дополнительна  вторична  обмотка 2К, питающа  токовую цепь второго датThe current circuit of the Hall sensor / is included in the controlled network in series with the winding 1K of the electromagnet and adjustable active resistance. An additional secondary 2K winding is applied to the core of the electromagnet M, supplying the current circuit of the second date.
