Abstract
The utility model discloses a cushion block structure between high voltage coil segments of a dry-type transformer and relates to the technical field of transformers. The structure comprises a coil and cushion blocks. The cushion blocks are arranged between the coil segments. Each cushion block is formed by conducting hot pressing on adhesive, alkali-free glass felt and alkali-free twist-free glass fiber twisted yarn and is 3.0 in thickness. The cushion blocks are non-elastic cushion blocks. The cushion block structure has the advantage that the used cushion blocks do not have elasticity, segment distance is ensured during vertical die filling of coils, electric strength of products is ensured, and operation reliability of products is improved.
Description
Technical field
The utility model relates to transformer technology field, be specifically related to the intersegmental cushion block structure of a kind of dry transformer high-tension coil.
Background technology
The high-tension coil of traditional Cast Resin Dry-Type Transformer, this high-tension coil is divided into multistage in the axial direction, every section of coil is that coiling layer by layer forms from the inside to the outside, between section and section, according to electric field strength, corresponding section insulation distance is set, originally at extremely corresponding insulation distance of intersegmental use 2.0 grid cloth stack pads, but in the time that coil is erect dress mould, the deadweight pressurization of coil, make intersegmental grid be furnished with contraction, can not ensure intersegmental distance, thereby affect the performance of transformer.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide a kind of dry transformer high-tension coil intersegmental cushion block structure, has ensured intersegmental distance, has ensured the electrical strength of product, has improved the operational reliability of product.
To achieve these goals, the utility model is to realize by the following technical solutions: the intersegmental cushion block structure of dry transformer high-tension coil, comprise coil and cushion block, between the section of coil and section, be lined with cushion block, described cushion block is thick 3.0 cushion blocks that adhesive, alkali-free glass felt and the hot pressing of alkali-free Non-twisting glass fibre folded yarn are made.
According to the intersegmental cushion block structure of above-mentioned dry transformer high-tension coil, wherein, described cushion block is nonelastic cushion block.
According to the intersegmental cushion block structure of above-mentioned dry transformer high-tension coil, wherein, the thickness in monolayer of described cushion block is 3mm, and cushion block is that multiple-layer stacked forms.
The beneficial effects of the utility model: the cushion block of use does not have elasticity, in the time that coil is erect dress mould, have ensured intersegmental distance, have ensured the electrical strength of product, have improved the operational reliability of product.
Brief description of the drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to Fig. 1, this embodiment is by the following technical solutions: the intersegmental cushion block structure of dry transformer high-tension coil, comprise coil 1 and cushion block 2, between the section of coil 1 and section, be lined with cushion block 2, thick 3.0 cushion blocks that described cushion block 2 is made for adhesive, alkali-free glass felt and the hot pressing of alkali-free Non-twisting glass fibre folded yarn.
It should be noted that described cushion block 2 is for nonelastic cushion block.
In addition, the thickness in monolayer of described cushion block 2 is 3mm, and cushion block 2 forms for multiple-layer stacked.
This embodiment has been cancelled grid cloth as section insulation between each section of coil, but thick 3.0 cushion blocks of being made by adhesive, alkali-free glass felt and the hot pressing of alkali-free Non-twisting glass fibre folded yarn in intersegmental employing, according to the requirement of intersegmental distance, respective thickness is added to, because this cushion block does not have elasticity, in the time that coil is erect dress mould, ensure intersegmental distance, ensure the electrical strength of product, improved the operational reliability of product.
More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
