Description
Technical field
The utility model belongs to field transformer, relates to a kind of single-phase three post 500KV superhigh pressure strong current transformer clamping piece magnetic shielding structures.
Background technology
Present stage, 1. single-phase three post 500KV superhigh pressure strong current transformer clamping piece magnetic shielding structures, normally magnetic screen size is equally large with the size of folder limb plate, because the leakage field of this transformer is very large, this structure magnetic screen area coverage is little, can not by efficient pressure swing device leakage flux, be withdrawn in Double layer iron yoke, also have leakage flux greatly and pass Transformer Winding end, winding overhang is caused to produce larger eddy current loss, cause winding overhang temperature rise too high, ageing of insulation is accelerated, and transformer sharply declines useful life; 2. folder adopts common Q 235 steel plate material to manufacture, and leakage flux, when through common Q 235 steel plate, produces larger supplementary load loss, and cause apparatus for fixing transformer to generate heat serious, load loss increases.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides the single-phase three post 500KV superhigh pressure strong current transformer clamping piece magnetic shielding structures that a kind of magnetic shield area coverage is large, avoid the too high and folder heating of winding overhang temperature rise.
The utility model is achieved by the following technical solution:
Single-phase three post 500KV superhigh pressure strong current transformer clamping piece magnetic shielding structures of the present utility model, winding technique is on iron core, the upper and lower two ends of iron core are iron yoke, the iron yoke left and right sides arranges folder, it is characterized in that: folder limb plate is vertically welded on folder, and the below of folder limb plate is lined with chock, magnetic shield is placed below chock, folder limb plate, chock and magnetic shield are linked together by bakelite bolt, place strutting piece in the below of magnetic shield, winding is compressed by pressing plate by strutting piece; Magnetic shield is extend into iron yoke stack sheet root place, the area of magnetic shield is greater than folder limb plate.
The left part of iron core Double layer iron yoke stack sheet and right part adopt D type yoke structure, magnetic shield are extend into the D type yoke structure place of iron yoke, increase the area coverage of magnetic shield.
Folder adopts and makes every magnetic steel plate 20Mn23AL material.
The beneficial effects of the utility model are:
1. add the area coverage of magnetic screen, can more leakage flux is withdrawn in Double layer iron yoke, effectively can avoid the too high phenomenon of winding overhang temperature rise;
2. too increase the contact area of strutting piece and transformer pressing plate simultaneously, add the anti-short circuit capability of transformer;
3. folder adopts and manufactures every magnetic steel plate 20Mn23AL material, reduces the supplementary load loss that leakage flux produces through folder, avoids folder superheating phenomenon.
Accompanying drawing explanation
Lower Fig. 1 is old structure schematic side view; Fig. 2 is new construction schematic side view.
In figure: 1, iron yoke, 2, folder, 3, bakelite bolt, 4, folder limb plate, 5, chock; 6, magnetic screen; 7, strutting piece, 8, pressing plate, 9, winding, 10D type yoke.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Single-phase three post 500KV superhigh pressure strong current transformer clamping piece magnetic shielding structures of the present utility model, winding 9 is wound on iron core, the upper and lower two ends of iron core are iron yoke 1, the iron yoke left and right sides arranges folder 2, and folder limb plate 4 is vertically welded on folder, and the below of folder limb plate is lined with chock 5, magnetic shield 6 is placed below chock, folder limb plate, chock and magnetic shield are linked together by bakelite bolt 3, place strutting piece 7 in the below of magnetic shield, winding is compressed by pressing plate 8 by strutting piece; Magnetic shield is extend into iron yoke stack sheet root place, the area of magnetic shield is greater than folder limb plate.
The left part of iron core Double layer iron yoke stack sheet and right part adopt D type yoke 10 structure, magnetic shield are extend into the D type yoke structure place of iron yoke, increase the area coverage of magnetic shield.
Folder adopts and makes every magnetic steel plate 20Mn23AL material.
In the utility model, iron core Double layer iron yoke stack sheet adopts part D type yoke structure, magnetic screen is extend into the D type yoke place in core window, increase the area coverage of magnetic screen, can, more longitudinal leakage flux, be withdrawn in Double layer iron yoke, effectively solve the longitudinal leakage flux of iron core, the local overheating phenomenon caused in Transformer Winding end, reduces the loss that longitudinal leakage flux produces.Folder adopts and manufactures every magnetic steel plate 20Mn23AL material, reduces the supplementary load loss that leakage flux produces through folder, avoids folder superheating phenomenon.
The D type yoke of chock 5 and iron yoke 1 is in same plane.
