An reactor is a device widely used in power systems, whose primary function is to provide reactive power compensation and voltage regulation by impeding current flow. Its core component—the iron core—features a unique structural design.

Structural Features of the Reactor Core

An reactor is a device widely used in power systems, primarily functioning by impeding current flow to achieve reactive power compensation and voltage regulation in circuits. Its core component—the iron core—features unique structural characteristics, which will be detailed below.

I. Iron Core Material

Reactor cores are typically assembled by stacking high-permeability silicon steel laminations, a material that offers advantages such as high magnetic permeability, low losses, and high resistivity—features that effectively minimize eddy current and hysteresis losses during operation.

II. Structural Form

The structural forms of reactor cores are mainly divided into two types: core-type and shell-type. The core-type core consists of multiple silicon steel laminations stacked into a cylindrical shape, featuring a simple structure and excellent heat dissipation. In contrast, the shell-type core is made by rolling silicon steel sheets into a cylindrical form, offering a shorter magnetic circuit and making it suitable for high-capacity applications.

III. Special Design

To reduce eddy current and hysteresis losses in the core and improve operational efficiency, the reactor core also incorporates several specialized designs. For instance, a multi-layer insulation structure is employed to prevent eddy currents from forming; a skewed-joint technique is used to minimize magnetic resistance at the joints; and a unique surface treatment process is applied to enhance the insulating properties of the silicon steel laminations.

IV. Fixing and Heat Dissipation

The iron core is securely fixed to the reactor's frame using a special mounting device, ensuring stable operation. Meanwhile, to enhance heat dissipation, the surface of the iron core is typically coated with a heat-conducting material or designed with cooling fins, significantly improving thermal efficiency. Additionally, the shape and dimensions of the iron core are specifically tailored based on the reactor's capacity and voltage rating.

V. Safety Protection

The reactor core also boasts excellent safety protection features. Its outer casing is made from insulating materials, providing superior waterproof, moisture-proof, and corrosion-resistant performance. Additionally, the core is equipped with a temperature-sensing device that automatically triggers an alarm and initiates cooling measures if temperatures rise too high.

In summary, the structural features of the reactor core primarily encompass material selection, design configuration, specialized engineering, mounting and heat dissipation, as well as safety protection measures. These characteristics enable reactors to operate efficiently and reliably within power systems, providing robust support for the safe and stable functioning of electrical networks.
