III. Permeability range of Low permeability nanocrystalline cores

1. Ultra-low core loss

100 KHz, 200 mT. Pcv≤200 mW/cm3.

It is better than the power ferrite PC48 material, less than 300 kHz, and has the lowest

loss among all current soft magnetic materials. Its loss is about 1/10~1/20 of MPP

materials.

2. High Bs

Bs is about 1.25 T, and is about 3 times of the power ferrite, which is also higher than

MPP materials. Its anti-saturation ability is significantly higher than that of ferrite material

and MPP materials with the same permeability and power.

3. Constant magnetic permeability

Compared with nanocrystalline materials with high permeability, its variation of

permeability with frequency is small.

4. Excellent temperature stability

At -40 ℃~150 ℃, the permeability changes in about 30%, which is significantly better

than the power ferrite high permeability material.

Typical application


Brief introduction: The current and voltage in

the power supply line are quite different, which

needs to be converted into a relatively uniform

current for the convenience of secondary

instrument measurement.In addition, the voltage

on the line is relatively high, so the direct

measurement is very dangerous. it requires an

electrical device which converts large current into

small current signal and acts as electrical isolation,

namely current reverser.

The national standard standardization

organization defines it as: A specia l

transformer that supplys power for measuring

instruments, instruments, relays, and other similar

appliances.

(1) Current reverser


Applications:

Electronic energy meter, precision

power meter, power transmitter,

current and voltage data acquisition,

relay protection, power transmitter,

ser vo motor, power monitoring

equipment, power system and other

d i g i t a l e l e c t r i c a l m e a s u r i n g

instruments, meters, intel l igent

electric control cabinet.



Constitution: It consists of two parts: the core and windings. Windings are

divided into primary and secondary windings. Primary winding is usually single turn or

several turns, and the turns of secondary windings is often more. The specific number

of turns is determined by the designed ratio of turns. It can be wound after setting the

precise number of turns by the automatic winding machine, and tested by the mutual

inductor coil number tester after winding to ensure the correctness of the coil turns.



Advantages:

1. High Bs. Strong resistance to current saturation, suitable for measuring strong

DC component current, especially more than DC 50 A.



Advantages:

2. Compared with Mn-Zn ferrite and high permeability nanocrystalline soft magnetic

cores, low permeability nanocrystalline cores don't need open a local air gap to

improve the anti-saturation capability, so that don't need expensive magnetic

shielding.

3. Low remanence, low loss, Br<20 mT, the remanence of nanocrystalline with

magnetic permeability of 200 is even lower than 3mT, and the effective local

permeability is very close to its linear permeability, and low magnetic loss, 100 kHz,

200 mT, the loss≤200 mW/cm3, which are beneficial to limit the phase deviation

between current and voltage of sensors, and reduce temperature rise to increase

accuracy.



Advantages：

4. Excellent temperature stability. The variation of µ between -40 ℃ and 120 ℃ is less

than 25%, and the change of µ with temperature is regular and almost linear, which is

beneficial to improve the limited working temperature and measurement accuracy of

measuring equipments.



Advantages：

5. Not easy to age above 100 ℃.

The low permeability nanocrystalline can be in the temperature environment above

100 ℃ for a long time, and the permeability variation is less than 1%, which is

conducive to improving the measurement accuracy in the high temperature

environment. Low permeability Co-based nanocrystalline cores' Bs is around 0.8 T,

which is not only lower than 1.25 T of low permeability nanocrystalline cores, and

more likely to be saturated, but also more likely to age above 100℃. Therefore, low

permeability nanocrystalline is an ideal alternative material for low permeability Co-

based nanocrystalline.



Advantages：

6. High natural cut-off frequency，cut-off frequency is above 2 MHz. (μ-f curves)

7. The permeability of cores is not sensitive to the external stress (such as coating,

coil winding).
