Description

Technical Field

[0001] This utility model relates to the technical field of iron-core reactors, and in particular to an iron-core reactor. Background Technology

[0002] For large-capacity iron-core reactors, a fastening structure is generally used where a through-bolt passes through the center of the iron core column and connects to the upper pressure beam, upper yoke, lower yoke, and base. As the diameter of the iron core column increases, the size of the through-bolt must be increased accordingly, resulting in a larger central opening size and a smaller effective cross-sectional area of ​​the iron core column. To maintain the magnetic flux density of the iron-core reactor, it is often necessary to increase the diameter of the iron core column or increase the amount of wire used, leading to a larger reactor size, increased material consumption, and a higher risk of noise problems. Summary of the Invention

[0003] The main purpose of this invention is to provide a core reactor that addresses the problems in the prior art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
