As we talked in the previous article "A New Type of Iron-based Amorphous Ultramicrystalline Magnetic Core", the product examples: CT076 (product coding) (electronic components in the transformation of China's State Grid Power System)

I. Basic introduction

Internal Diameter (ID): 14 m

External Diameter (OD): 21 M

Height (HT): 8M

50 H Z - 20 KHz inductor: 9 - 13 uH (optional)

Coercive force: less than 0.3 A/m

Saturated magnetic induction: 1.15T

Residual magnetic induction: below 20mT

Inductance fluctuation of 50 Hz - 20 KH Z is less than 3%

II. Applications:

Power system measurement and protection, new leakage protector magnetic ring, ultra-high precision micro current transformer, etc.

III. Product Features:

Multi-band Inductance Stability (Test Frequency from Power Frequency to 20 K H Z High Frequency, Core Inductance Impedance Change Rate below 3%)

The linear working range of a single frequency band is above 0 A/m~35 A/m (with the increase of external magnetic field strength H, the self-magnetic induction intensity B increases synchronously in a certain proportion, and the permeability is constant in this linear working band).

IV. Application prospect

(I) Ultra-high Precision Current Transformer

The product can be tested in different percentages (5% - 120%), the difference is less than 0.05% and the change is not more than 0.018%. The angle difference of each test point is less than (+1.5). The working linear section is long and can cover the working section of the current transformer. It guarantees that the transformer is always in a linear working state in the process of using, and provides a strong guarantee for precise testing current.

(II) A new type of leakage-protected transformer

The product is different from the common product which fails to protect the movement point under different operating frequencies (clutter interference) is prone to deviation. The product is in multi-frequency band.

The magnetic permeability is constant and consistent, which can ensure that the action point is not deviated and the work is stable under the condition of clutter interference.

(III) EMI filter inductor

The product has low frequency, small gap between high frequency inductance, linear relationship between impedance and frequency, low insertion loss and excellent distributed capacitance. In the complex working environment, it has much better performance than conventional products.

V. The company's product characteristics

Different from other products of the same type on the market, our products can guarantee the electromagnetic properties of highly linear products at the same time, can ensure the remanence of products less than 20mT (200Gs), coercivity less than 0.3A/m, for product stability, loss (work heat change), multiple impact performance change rate and so on have high quality protection, with irreplaceable superior performance.
