Abstract

The utility model relates to a movable middle-yoke conjugate type rectifying transformer, comprising main iron cores. Middle yokes of the main iron cores are movable middle yokes and comprise front middle yokes and rear middle yokes which are symmetrical in shape; the front middle yokes and the rear middle yokes respectively consist of a middle-yoke iron core and a fixed pressing plate; the middle-yoke iron cores are laminated by silicon steel sheets with set sheet types and are wound into a whole with the fixed pressing plates by using winding belts; and the fixed pressing plates are provided with bolt holes; the front middle yokes and the rear middle yokes are fixed at the middle waist parts of the main iron cores in a clamping manner by fastening bolts penetrating through the bolt holes. In the movable middle-yoke conjugate type rectifying transformer, the whole iron core does not need to turn over when in assembly, so that the assembly working hour can be shortened; since the section of the movable middle yokes is small and only one sheet type is needed, the materials such as iron core materials and transformer oil and the like can be saved, the idle-load loss is reduced, the sheet laminating working hour is shortened, the material utilization ratio is improved, the whole processibility is greatly improved, and simultaneously the heights and the transportation heights of the whole iron core and the transformer can be reduced.

Description

The conjugation-type rectifier transformer of yoke in a kind of activity

Technical field

The utility model relates to a kind of transformer, the conjugation-type rectifier transformer of yoke in particularly a kind of activity.

Background technology

Conjugation-type rectifier transformer device status becomes two parts up and down, and yoke adopts stationary structure in traditional conjugation-type iron core, and there is following weak point in this kind rectifier transformer:

1, up and down during device body suit iron core need upset, the assembly process complexity, man-hour is long.

2, owing to iron core needs upset, the mechanical strength of folder in must considering, general middle yoke heart cross section is bigger, is about about 80% of main stem stem cross section, and consumable material is bigger.

3, because middle yoke is a fixed structure, middle yoke need cause the lamination type more with main core lamination together, and the lamination time is long, and stock utilization reduces.

Summary of the invention

The purpose of this utility model is to provide the conjugation-type rectifier transformer of yoke in a kind of activity, to overcome the existing above-mentioned deficiency of prior art.

The technical scheme that the utility model is taked is: the conjugation-type rectifier transformer of yoke in a kind of activity, comprise main core and middle yoke, yoke is a yoke in the activity in described, comprise in shape symmetry preceding yoke in the yoke and back, yoke constitutes by the middle yoke heart and fixation clip in the front and back, in the yoke heart with setting sheet type silicon steel sheet lamination and being with and fixation clip tightly wraps in aggregatesly with tightly wrapping, have bolt hole on the fixation clip, yoke is fixedly clamped at the middle waist of main core by the fastening bolt that passes bolt hole in the front and back.

Its further technical scheme is: described fixation clip be one " in " the font insulation board, forward projection's shape of the shape of its lateral part and the middle yoke heart is consistent, be rectangle, the protuberance up and down at its middle part respectively has a bolt hole.

Owing to take above technical scheme, the conjugation-type rectifier transformer of yoke has following beneficial effect in a kind of activity of the utility model:

1, since in a kind of activity of the utility model the middle yoke of its conjugation-type iron core of conjugation-type rectifier transformer of yoke be movable, folder in the cancellation, assemble the lower part device after one's death earlier during assembling, put into the activity yoke heart again, integral core need not overturn can be inserted in the first half coil, when shortening the assembler.

2, since in the activity magnetic flux of yoke have only main stem stem magnetic flux 2% in, in a kind of activity in the conjugation-type rectifier transformer activity of yoke yoke heart cross section only need get about 10% of main stem stem cross section, saved core material, lowered no-load loss.

3, since in a kind of activity of the utility model in the activity of conjugation-type rectifier transformer of yoke the yoke cross section very little, only need a kind of type, independent closed assembly, not only can shorten lamination man-hour, stock utilization and whole manufacturability have been improved, can reduce simultaneously the height of whole iron core and transformer, save materials such as core material and transformer oil, steel, also can reduce the transformer shipping height.

Be further described below in conjunction with the technical characterictic of drawings and Examples the conjugation-type rectifier transformer of yoke in a kind of activity of the utility model.

Embodiment:

Embodiment:

The conjugation-type rectifier transformer of yoke in a kind of activity, comprise main core 1 and middle yoke, yoke is a yoke in the activity in described, comprise in shape symmetry preceding yoke I 2 in the yoke I 1 and back, yoke constitutes by the middle yoke heart 5 and fixation clip 2 in the front and back, in the yoke heart 5 usefulness set sheet type silicon steel sheet lamination and also be with 3 itself and fixation clip 2 to be tightly wrapped in aggregates with tightly wrapping, have bolt hole 21 on the fixation clip 2, yoke is fixedly clamped at the middle waist of main core by the fastening bolt 4 that passes bolt hole in the front and back.

Described fixation clip 2 be one " in " the font insulation board, forward projection's shape of the shape of its lateral part and the middle yoke heart 5 is consistent, be rectangle, the protuberance up and down at its middle part respectively has a bolt hole 21.

The foregoing description is one of preferable embodiment of the utility model, and in actual applications, the number of the shape of fixation clip and the bolt hole of being opened can be set according to the specification size of rectifier transformer.
