Abstract
The utility model relates to an iron core insulating member for a dry type transformer, comprising two long insulating web plates and three short insulating web plates, wherein a plurality of long insulating cushion blocks arranged longitudinally are arranged on the long web plates horizontally and uniformly; the first short web plate is fixedly connected on the two long cushion blocks at the adjacent ends of the two long web plates; the long cushion block at the other end of the first long web plate is connected with one end of the second short web plate, and the other end of the second short web plate is symmetrically provided with one long cushion block; the long cushion block at the other end of the second long web plate is connected with one end of the third short web plate, and the other end of the third short web plate is symmetrically provided with another long cushion block; a pull plate inserting groove is arranged between the two long cushion blocks at the two ends of each short web plate respectively; and the positions of fixed holes on corresponding clamping pieces on the two long web plates are respectively provided with a through hole. In the iron core insulating member, the structure is simple, the use and the installation are convenient, and the insulating performance of an iron core can maintain long-term stability, so that the requirement of the dry type transformer on long-term and safe operation can be met.
Description
Technical field:
The utility model relates to a kind of dry-type transformer core insulation member.
Background technology:
At present, along with the fast development of city size, heavy construction is increasing, and the dry-type power transformer that possesses fire resistance property, non-maintaining characteristics is used more and more widely.Be 30 years the useful life of general dry-type transformer, requires the each several part insulating part of transformer to possess stable electric property under working environment.Because dry-type transformer often is applied to wet environments such as basement,, can produce harm to the security of operation of transformer if the insulating part insulation property are bad.What dry-type transformer iron core insulation was at present adopted is thick epoxy glass fabric plate structure.For preventing the epoxy resin bonded fiber moisture absorption, need varnish on its surface, but the insulating varnish on epoxy resin bonded fiber surface is damaged easily in the manufacture process of transformer and in the product use, thereby influences the insulation property of iron core, the safe operation of harm transformer.
The utility model content:
The utility model provides a kind of dry-type transformer core insulation member, it is simple in structure, and is easy to install and use, can make the permanent maintenance of insulation property of iron core stable, satisfy the demand of dry-type transformer long-term safety operation, solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises two blocks of long webs of insulation and three blocks of insulation stenogastry plates, on long web, laterally evenly be laid with some the long cushion blocks of insulation that vertically are provided with at interval, the first stenogastry plate is connected on two long cushion blocks of two long web abutting ends, the long cushion block of the first long web other end links to each other with an end of the second stenogastry plate, the other end at the second stenogastry plate is arranged with a long cushion block, the long cushion block of the second long web other end links to each other with an end of the 3rd stenogastry plate, the other end at the 3rd stenogastry plate is arranged with a long cushion block, be respectively equipped with an arm-tie insertion groove between the two long cushion blocks at every stenogastry plate two ends, the position of the fixing hole on corresponding folder on the two block length webs is respectively equipped with a through hole.
The utility model is simple in structure, and is easy to install and use, can make the permanent maintenance of insulation property of iron core stable, satisfies the demand of dry-type transformer long-term safety operation.In addition, because long cushion block interval layout on long web makes between transformer folder and the iron core and leaves heat-dissipating space, improved the heat-sinking capability of transformer.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1, long cushion block; 2, the first stenogastry plate; 3, the first long web; 4, the second stenogastry plate; 5, the second long web; 6, the 3rd stenogastry plate; 7, arm-tie insertion groove; 8, through hole.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Shown in Fig. 1～2, the utility model comprises two blocks of long webs of insulation and three blocks of insulation stenogastry plates, on long web, laterally evenly be laid with some the long cushion blocks 1 of insulation that vertically are provided with at interval, the first stenogastry plate 2 is connected on two long cushion blocks 1 of two long web abutting ends, the long cushion block 1 of first long web 3 other ends links to each other with an end of the second stenogastry plate 4, the other end at the second stenogastry plate 4 is arranged with a long cushion block 1, the long cushion block 1 of second long web 5 other ends links to each other with an end of the 3rd stenogastry plate 6, the other end at the 3rd stenogastry plate 6 is arranged with a long cushion block 1, be respectively equipped with an arm-tie insertion groove 7 between the two long cushion blocks 1 at every stenogastry plate two ends, the position of the fixing hole on corresponding folder on the two block length webs is respectively equipped with a through hole 8.
Described long web, stenogastry plate and long cushion block 1 all adopt bulk mould fiberglass plastic to make, and have the good insulation performance performance.Long cushion block 1 is bonded on long web and the stenogastry plate by H level epoxide-resin glue.
During use, the utility model member is installed between transformer folder and the iron core, the long web, stenogastry plate and the long cushion block 1 that adopt bulk mould fiberglass plastic to make are nonhygroscopic, under damp and hot environmental condition, can keep good electrical insulation properties for a long time, can make the permanent maintenance of insulation property of iron core stable, satisfy the demand of dry-type transformer long-term safety operation.In addition, because long cushion block 1 interval layout on long web makes between transformer folder and the iron core and leaves heat-dissipating space, improved the heat-sinking capability of transformer.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
