Abstract
The utility model discloses an insulation device for a dry type transformer clamp and relates to the technical field of transformers. The insulation device for the dry type transformer clamp comprises a plurality of cushion blocks and a clamp web, the cushion blocks are bonded on the clamp web in parallel, and the clamp web is an epoxy plate; each cushion block is composed of adhesive, an alkali-free glass mat and alkali-free twist-less glass fiber twisted yarn in a hot pressing mode. By means of the insulation device for the dry type transformer clamp, the dry type transformer clamp is difficult to be affected with damp, the moisture resistance, dust resistance and corrosion resistance of the transformer are reinforced, the electric strength is improved, and the service life of the transformer is increased.
Description
Technical field
The utility model relates to transformer technology field, be specifically related to a kind of seal that is applied to dry type transformer clamp.
Background technology
Dry-type transformer with its there is difficult combustion, non-maintaining, body is little, lightweight, loss is low, the feature that reliability is high has met those and should make transformer go deep into load center again without danger of combustion, as big city skyscraper, subway, airport, power station etc.But the protection against the tide of the clamp insulation material that at present dry-type transformer uses, dustproof, corrosion resistance is poor, thereby cause its electrical strength to reduce, and then to affect it be useful life.
Summary of the invention
For the deficiency existing in prior art, the utility model object is to be to provide a kind of seal that is applied to dry type transformer clamp, not moisture-sensitive of the clamp insulation of dry-type transformer, make transformer strengthen its protection against the tide, dustproof, corrosion resistance, improve electrical strength, increase transformer useful life.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of seal that is applied to dry type transformer clamp, comprise cushion block and folder web, multiple cushion blocks are parallel to stick on folder web, and described folder web is epoxy plate; Described cushion block is the cushion block of being made up of adhesive, alkali-free glass felt and the hot pressing of alkali-free Non-twisting glass fibre folded yarn.
According to above-mentioned a kind of seal that is applied to dry type transformer clamp, wherein, described cushion block is cross-over block, and thickness is 6-10mm, and width is 30mm.
According to above-mentioned a kind of seal that is applied to dry type transformer clamp, wherein, the temperature resistant grade of described cushion block is H level.
According to above-mentioned a kind of seal that is applied to dry type transformer clamp, wherein, the bending strength of described cushion block is more than or equal to 350Mpa.
Not moisture-sensitive of clamp insulation of the present utility model, makes transformer strengthen its protection against the tide, dustproof, corrosion resistance, improves electrical strength, increases transformer useful life.
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;
Fig. 2 is the vertical view of Fig. 1.
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. 1-2, this embodiment by the following technical solutions:: a kind of seal that is applied to dry type transformer clamp, comprise cushion block 1 and folder web 2, multiple cushion blocks 1 are parallel to stick on folder web 2, described folder web 2 is epoxy plate; The cushion block of described cushion block 1 for being made by 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 1 is for cross-over block, thickness is 6-10mm, and width is 30mm.
Temperature resistant grade that it should be noted that described cushion block 1 is H level.
In addition, the bending strength of described cushion block 1 is more than or equal to 350Mpa.
This embodiment insulate by paste cross-over block on folder web 2, insulation effect is good, and not moisture-sensitive of clamp insulation that can dry-type transformer makes transformer strengthen its protection against the tide, dustproof, corrosion resistance, improve electrical strength, increase transformer useful life.
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.
