Abstract
The utility model discloses a binding band structure for a transformer iron core. The binding band structure comprises iron core pulling frames and binding bands, wherein the iron core pulling frames are arranged on an iron core clamping piece; the binding bands are arranged on iron yokes among iron-core columns; after the binding bands are bound and wound at the iron yokes, the two ends of each binding band are fixed on each iron core pulling frame. The binding band structure is characterized in that the binding bands are arranged on the iron yokes among the iron-core columns by two or more groups. The binding band structure can improve the integrity of the iron yokes.
Description
Technical field
The utility model relates to a kind of strap configurations that is applicable to the high-power transformer iron core.
Background technology
When carrying out the transformer core closed assembly, the clamping of last lower yoke mainly realizes the pulling force of iron core folder by the iron core strutting piece.Because the iron core folder is limited to the clamping degree of iron core, falls sheet and buckling phenomenon for preventing lamination, need on the iron core folder, to assemble iron core and try to stop people from fighting each other, secured core bandage on trying to stop people from fighting each other is in order to the secured core sheet.
Along with the continuous development of transformer superhigh pressure, big capacity (220kV and above, 200MVA and more than) technology, the diameter and the weight of transformer core constantly increase.When iron core diameter increased, the closed assembly thickness of iron core constantly increased, and original iron core strap configurations is fixed (Fig. 1) for fix several iron core bandages on trying to stop people from fighting each other by place's iron core on the iron yoke between the two column iron core posts.For conventional iron core diameter smaller transformer, the iron core bandage is the iron yoke effectively fixedly; But for superhigh pressure, high-power transformer, the amplitude that iron core diameter and untanking mass increase has exceeded the fastening degree of conventional iron core bandage, and conventional iron core strap configurations can't satisfy the needs of high-power transformer iron core bulk strength.If still adopt the iron core strap configurations of Fig. 1, along with the increase of iron core diameter, the distance of stem both sides bandage increases can be bigger, even increase bandage quantity, span is still excessive between bandage, and the tension effect of iron yoke is weakened; Add that transformer capacity increases, iron core diameter increases the situation of the iron core weight increase that brings, then the iron yoke can not be effectively fixing near the stem side, lamination still can take place fall sheet and buckling phenomenon.
Summary of the invention
The purpose of this utility model provides a kind of iron core strap configurations that satisfies high-power transformer iron core bulk strength.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of transformer core strap configurations, comprise that the iron core that is arranged on the iron core folder tries to stop people from fighting each other, be arranged in the bandage on the iron yoke between the iron core column, described bandage bundle is behind the iron core return yoke, the bandage two ends are fixed on iron core tries to stop people from fighting each other, it is characterized in that this bandage is arranged on the iron yoke between the iron core column by two or more sets.
In the such scheme, described bandage is the 3-4 group, and every group is the 2-3 root.The bandage of respectively organizing that is arranged on the lower yoke is provided with supporting bracket.
The utility model has the advantages that:
Under the situation that does not roll up bandage quantity, the globality of iron yoke is strengthened;
Under the situation of space anxiety between the iron core column, bandage quantity is effectively disperseed, save the space.
Description of drawings
Fig. 1 is existing a kind of high-power transformer iron core strap configurations.
Fig. 2 improves the big capacity iron core strap configurations in back for the utility model.
Among the figure: 1, iron core folder; 2, iron core is tried to stop people from fighting each other; 3, iron core bandage; 4, iron core column; 5, iron yoke; 6, supporting bracket.
Embodiment
As shown in Figure 2, a kind of transformer core strap configurations, behind the fixed head of avoiding on the iron core folder 1 on iron core folder horizontal direction the welding iron core try to stop people from fighting each other 2, iron core bandage 3 is arranged on the iron yoke 5 between the iron core column 4, the bandage bundle is behind iron yoke 5, two ends are fixed on iron core and try to stop people from fighting each other on 2, and this bandage is evenly arranged on the iron yoke 5 between the iron core column 4 by two or more sets.In the present embodiment, bandage is designed to 3 groups, and every group is 2.Wherein, the bandage of respectively organizing that is arranged on the lower yoke is provided with supporting bracket 6, is used to prevent the compressing of coil to bandage.
Claims (3)
1. transformer core strap configurations, comprise that the iron core that is arranged on the iron core folder tries to stop people from fighting each other, be arranged in the bandage on the iron yoke between the iron core column, described bandage bundle is behind the iron yoke, the bandage two ends are fixed on iron core tries to stop people from fighting each other, it is characterized in that this bandage is arranged on the iron yoke between the iron core column by two or more sets.
2. transformer core strap configurations as claimed in claim 1 is characterized in that, described bandage is the 3-4 group, and every group is the 2-3 root.
3. transformer core strap configurations as claimed in claim 1 is characterized in that, the bandage of respectively organizing that is arranged on the lower yoke is provided with supporting bracket.
