What is a nanocrystalline core?

2021-10-11

The nanocrystalline magnetic core is a small part with magnetic permeability. The center of the nanocrystalline magnetic core has small nanocrystalline grains. The working principle of the nanocrystalline magnetic core is to absorb the common mode current in the cable through the principle of induction heating. And it is converted into heat and dissipated.


The use of common mode inductance of nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage at the same time. Because of the unique characteristics of nanocrystalline cores, it is well used in some high-power system industries. Applications.


Product performance:


Electric energy meters, power meters, ammeters, electrical measuring equipment and other instrumentation fields. Various types of power current transformers in power transmission and distribution power monitoring systems. Leakage protection, relay protection, servo motor protection, fire monitoring, etc.


Current and voltage data sampling, etc. Product performance:


High initial permeability. The product has high precision, small error (ratio difference and angle difference), high saturation magnetic induction, and wide detection current range. Low coercivity, more stable product performance, more sensitive to weak current induction. Good thermal stability. Small changes in permeability and error thermal shock


High Curie temperature and excellent temperature characteristics. Long-term working temperature: -50~+130℃


Applicable fields:


Mainly used in the production of miniature precision current transformers, power current transformers, Hall sensors, open-close current transformers, power transmitters, etc.


The terminal should be used for:


Electric energy meters, power meters, ammeters, electrical measuring equipment and other instrumentation fields. Various types of power current transformers in power transmission and distribution power monitoring systems. Current and voltage data sampling for leakage protection, relay protection, servo motor protection, fire monitoring, etc.
