Vad är fluxgate-strömsensor och dess funktionsprincip?

Arbetsprincipen för högprecisionsfluxgateströmsensor:

Under inverkan av positiv och negativ excitationsström används den lättmättade magnetiska kärnan för att få induktansen hos den magnetiska kärnan att ändras med storleken på excitationsströmmen, så att magnetkärnans magnetiska flöde ändras kontinuerligt.

De fluxgate current sensor uses the non-linear relationship between the magnetic induction intensity and the magnetic field intensity of the high magnetic permeability core in the measured magnetic field under the saturation excitation of the alternating magnetic field to measure the weak magnetic field. This physical phenomenon seems to be a “gate” to the measured ambient magnetic field. Through this “gate”, the corresponding magnetic flux is modulated and an induced electromotive force is generated. This phenomenon is used to measure the magnetic field generated by the current, so as to indirectly achieve the purpose of measuring the current.

Grundläggande principer för Fluxgate-sensordrift

I den magnetiska kretsen, för att detektera ett magnetfält som är lika med noll magnetiskt flöde, måste sekundärspolen exciteras av den nödvändiga strömmen. I en miljö med noll magnetiskt flöde förstärks sensorns ström genom sekundärspolen, vilket bekräftas vara proportionellt mot den uppmätta primärströmmen. . Ip=Ns. Den ferromagnetiska kärnan Is och hjälpspolen bildar en mättad induktor. Vid noll magnetiskt flöde baseras detekteringen av sensorns magnetiska krets på förändringen av induktansen hos induktansen.
