Knowing this knowledge is very useful for using one-piece inductors
Feb 27 , 2021
One-piece inductors are also called: Molded inductors include magnets and windings themselves. Surface-mount inductors. The key difference from general output power control inductors depends on the fact that one-piece inductors have a winding first, and then The metal is formed by die-casting of powdered and filled aluminum with magnetic material, and the leads are drawn out from the side and then...

The situation of China inductor market this year
Feb 27 , 2021
1. Overview of inductors Inductors are electronic components that can convert electrical energy into magnetic energy and store it. The structure of the inductor is similar to that of a transformer, but it has only one winding. The inductor has a certain inductance, it only blocks the change in the amount of current. If the inductor has no current through it, it will try to block the current throug...

Let us learn about these kinds of inductors
Dec 17 , 2020
The inductor will have a blocking effect on the current passing through the inductor under the condition of alternating current. The higher the frequency of the inductor, the greater the blocking effect. This type of condition is called inductive reactance and is measured in ohms (Ω). Said. Inductor characteristic 2: The current passing through the inductor will not change suddenly, the current wi...

Principle and main function of transformer
Dec 17 , 2020
Current transformer is an electronic component that can convert electrical energy into magnetic energy, store it under appropriate conditions, and release it and then convert it into electrical energy. The most important role of inductor is electromagnetic conversion. All electrical conductors (transmission lines) will cause electromagnetic fields when passing current. When the electrical con...

How to choose split core current transformer correctly?
Dec 17 , 2020
Current transformers can be divided into high voltage and low voltage, which are mainly distinguished by the highest voltage of the equipment. Generally, 10KV or more is high voltage, 10KV is medium voltage, and 1kv and below are low voltage. Split core current transformer is mainly used in low voltage, because SCT must be opened and closed, which makes SCT unable to carry out effective sealing an...

Analysis and improvement of split core current transformer
Dec 17 , 2020
Split core current transformer, as its name implies, is a current transformer that can be opened and closed on the primary circuit (the side of the measured current circuit, usually a cable or parent card), and is a secondary device by sensing the current on the primary circuit Take measurements or protect relays. In recent years, although the development of China's distribution network has i...

A brief introduction to zero sequence transformer
Oct 28 , 2020
Zero-sequence current transformers are also called residual current transformers, ground current transformers or leakage current transformers. They are usually used in power fire protection equipment. When the power system generates zero-sequence grounding current, it is used in conjunction with the relay protection device for pre-protection Or monitor. The basic principle of the zero sequence cur...

The future development direction of electronic transformers
Oct 28 , 2020
According to media reports, the future research and development directions of electronic transformers include passive sensing, structural combination, functional reuse, and component standardization. Passive sensing: Due to the technical advantages of passive sensing, independent ECT sensing components will tend to be passive. This includes that active sensors will be self-powered and move towards...
