Abstract
The utility model relates to a high-strength heat-resisting iron core inter-plate oil passage structure, and belongs to the technical field of transformer equipment. According to the technical scheme, the oil passage structure comprises an iron core plate (1) and a plurality of ceramic plates (2). The ceramic plates (2) are evenly bonded on the iron core plate (1) through an electrical white emulsion. Each ceramic plate (2) is of a circular structure. The distance between every two adjacent ceramic plates (2) ranges from 4 mm to 6 mm. The iron core plate (1) is an iron core plate layer arranged at the position, where an inter-plate oil passage needs to be placed, of a transformer iron core. The high-strength heat-resisting iron core inter-plate oil passage structure has the advantages of improving the heat resistance and compression strength of the inter-plate oil passage of the iron core, and being simple in structure, easy to produce, high in mechanical strength, free of contraction in the drying process, good in overall attachment strength, not prone to deformation or aging, and high in temperature resistance level, stability and heat dispersion performance.
Description
Technical field
The utility model relates to oil channel structure between a kind of high strength heat resistant lamination, belongs to transformer equipment technical field.
Background technology
The no-load loss of transformer, no-load loss unshakable in one's determination produces heat and makes heating unshakable in one's determination, in order to prevent the local overheating that produces unshakable in one's determination, conventionally will between internal sheets unshakable in one's determination, cooling oil duct be set, to improve heat dispersion unshakable in one's determination.Oil duct between lamination, is spliced by the insulation board that is stained with insulating stay conventionally, generally adopts the cardboard of 1mm to be stained with the stay formation insulating oil duct that 5mm is thick.In the time of practical operation, because insulation board is immersed in high temperature transformer oil for a long time, can there is aging phenomenon in this structure, between lamination, the mechanical strength of oil duct and thermal endurance class can constantly reduce, thereby affect the useful life of transformer.
Utility model content
The utility model object is to provide oil channel structure between a kind of high strength heat resistant lamination, effectively improves the heat-resistant pressure-resistant intensity of oil duct between lamination, solves the problem existing in background technology.
The technical solution of the utility model is:
Oil channel structure between a kind of high strength heat resistant lamination, comprise lamination and potsherd, several potsherds are evenly bonded on lamination by electrician's white glue with vinyl, the rounded structure of described potsherd, thick 4-6mm, distance between adjacent two potsherds is 30-60mm,, described lamination is one deck lamination that transformer core need be placed oil duct place between sheet.
Described lamination is one deck lamination that transformer limit iron prop iron core or iron yoke iron-core need be placed oil duct place between sheet.
Adopt the utility model, use electrician's white glue with vinyl to be evenly bonded on lamination several potsherds, form oil channel structure between lamination, can effectively improve the heat-resistant pressure-resistant intensity of oil duct between lamination.
The beneficial effects of the utility model are: improved the heat-resistant pressure-resistant intensity of oil duct between lamination, simple in structure, be easy to realize, mechanical strength is high, dry without shrinking, entirety tightness is good, and not yielding, thermal endurance class is high, be difficult for agingly, stability is strong, perfect heat-dissipating.
Accompanying drawing explanation
Fig. 1 is oil channel structure schematic diagram between the iron prop lamination of the utility model transformer limit;
Fig. 2 is oil channel structure schematic diagram between the utility model transformer yoke lamination;
In figure: lamination 1, potsherd 2.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Oil channel structure between a kind of high strength heat resistant lamination, comprise lamination 1 and potsherd 2, the described lamination 1 transformer limit iron prop one deck lamination that needs to place oil duct place between sheet unshakable in one's determination, the thick 4-6mm of the rounded structure of described potsherd 2, several potsherds 2 use electrician's white glue with vinyl to be evenly bonded on lamination 1, and the distance between adjacent two potsherds 2 is 30-60mm.
With reference to accompanying drawing 2, oil channel structure between a kind of high strength heat resistant lamination, comprise lamination 1 and potsherd 2, described lamination 1 need be placed one deck lamination at oil duct place between sheet for transformer fe yoke iron-core, the thick 4-6mm of the rounded structure of described potsherd 2, several potsherds 2 use electrician's white glue with vinyl to be evenly bonded on lamination 1, and the distance between adjacent two potsherds 2 is 30-60mm.
