Description

Technical Field

[0001] The utility model relates to the technical field of reactor clamping pieces, and particularly relates to a yoke clamping piece of a triangular dry-type iron core reactor. Background Art

[0002] The triangular dry-type iron core reactor includes 3 reactors distributed in a triangular shape and is clamped by yoke clamping pieces. The existing yoke clamping pieces are three independent channel steels. The reactors are connected to the nail support plates on the channel steels through a pressure nail plate and a pressure nail. There is no effective support between the channel steels on each reactor, and it is difficult to ensure the levelness and stability of the three reactors, resulting in uneven heights of the nail support plates on the channel steels, uneven force on the coils, and easy generation of slight vibrations during operation, which has an adverse impact on the safe operation of the reactor. Summary of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] In order to overcome the deficiencies of the prior art, a yoke clamping piece of a triangular dry-type iron core reactor is proposed, which can ensure the stability between the 3 channel steels and make the clamping piece more stable.

[0005] (2) Technical Solutions

[0006] The utility model is realized through the following technical solutions: A yoke clamping piece of a triangular dry-type iron core reactor is proposed, which includes three channel steels centrally arrayed in a disc structure. The disc member includes an upper disc and a lower disc arranged concentrically. One end of the channel steel is fixed between the upper disc and the lower disc. An annular inner nail support plate is arranged directly below the disc structure. An outer nail support plate is arranged along the length direction of the channel steel. The inner nail support plate and the outer nail support plate are located in the same plane and are connected to the pressure nail plate on the reactor through a pressure nail.

[0007] Further, the included angle between two adjacent channel steels is 120 degrees.

[0008] Further, a notch is opened on the lower disc, and a vertical plate for fixing the inner nail support plate is welded vertically in the notch.

[0009] (3) Beneficial Effects

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The yoke clamping piece of the triangular dry-type iron core reactor mentioned in the utility model connects the three channel steels through the set disc structure. The upper disc and the lower disc of the disc structure can effectively fix the three channel steels so that they will not shake up and down or left and right. The inner nail support plate is arranged in an annular structure to ensure that all the pressure nails can be located in the same plane, ensuring its flatness. Description of the Drawings

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0016] As Figure 1 - Figure 2 shown, for the yoke clamp of a triangular dry-type iron-core reactor, the included angles of the three channel steels are equally distributed at 120 degrees. The channel steel 1 is sequentially connected and fixed into a whole by the disc member 2 welded by the upper disc 21 and the lower disc 22. The upper disc 21 and the lower disc 22 are concentrically arranged. The upper disc 21 and the lower disc 22 can effectively fix the three channel steels 1 so that they will not shake up and down or left and right. A notch is opened on the upper surface of the lower disc 22, and a vertical plate 7 for fixing the inner pressure nail support plate 3 is welded vertically in the notch. Since the internal space is very limited, the inner pressure nail support plate 3 is of an annular structure and is provided with 6 openings for inserting pressure nails. The 6 pressure nails are all fixed on the annular structure, so the flatness is guaranteed. An outer pressure nail support plate 4 is arranged in the length direction of the channel steel 1. The inner pressure nail support plate 3 and the outer pressure nail support plate 4 are in the same plane and are connected to the pressure nail plate 6 on the reactor 5 through pressure nails. The two pressure nail plates 6 of the reactor 5 are respectively connected to the inner pressure nail support plate 3 and the outer pressure nail support plate 4, ensuring the stability of the reactor 5.

[0017] The above-described embodiments are only used to describe the preferred implementation manners of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model should all fall within the protection scope of the present utility model. The technical content claimed by the present utility model has been fully recorded in the claims.
