Description

Technical Field

[0001] This utility model belongs to the field of reactors, and in particular relates to a double-core fixing structure for a magnetically controlled reactor. Background Technology

[0002] With the rapid development of the power industry, industries such as railways, coal, metallurgy, and power substations have experienced unprecedented growth. This has also brought about a series of problems. Various ultra-high voltage and extra-high voltage power grids have been put into operation one after another, and the requirements for power supply quality and reliability are becoming increasingly higher. Various reactive power compensation devices and electrical products have emerged as a result. Among them, magnetically controlled reactors have been vigorously developed due to their stable performance and ability to perform inductive reactive power compensation for power systems.

[0003] Currently, magnetically controlled reactors generally employ a dual-core structure. Ensuring the balance of the two cores during assembly and minimizing installation errors remains a significant challenge during manufacturing. Therefore, there is an urgent need to research a stable dual-core fixing structure for magnetically controlled reactors to guarantee their performance. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology by designing a magnetically controlled reactor double core fixing structure. This structure is simple in construction, easy to operate, and can effectively solve the problem of excessive installation error of the double reactor body.

[0005] A magnetically controlled reactor dual-core fixing structure includes a first core, a second core, and a base plate, wherein: the outer clamps and inner clamps on both sides of the first core and the second core are connected by insulating fasteners, the first inner clamp and the first outer clamp, the second inner clamp and the second outer clamp are respectively connected and fastened to the upper and lower magnetic plates by fasteners, and the bottom magnetic plate is fixed on the base plate.

[0006] A non-magnetic plate and an insulating component are provided between the outer clamp and the inner clamp and the core column. The non-magnetic plate is fixed by the positioning component on the outer clamp and the inner clamp.

[0007] The iron core is made of alternating long and short plates, and has air bars of the same size and evenly distributed.

[0008] An insulating buffer layer is provided on the outer periphery of the iron core, which is then potted with resin.

[0009] The beneficial effects of this utility model are as follows:

[0010] The non-magnetic plate is fixed to the inner and outer clamps by positioning components, which effectively ensures the verticality and flatness of each core column during the core stacking process.

[0011] The outer and inner clamps secure the first and second iron cores to the upper and lower magnetic plates simultaneously with fasteners, ensuring the balance of the dual-core structure and reducing assembly errors.

[0012] The bottom magnetic plate is fixed to the base plate, ensuring the overall stability of the magnetically controlled reactor.

[0013] The core column is made of stacked long and short pieces with evenly distributed air, which effectively ensures the uniformity of magnetic flux distribution.

[0014] After the core columns are stacked, they are potted with resin around their perimeter to reduce noise and heat generation during product operation. Attached Figure Description
