Abstract
The utility model relates to an iron core oil passage structure of a large transformer, and belongs to the technical filed of transformers. The technical scheme includes that the iron core oil passage structure comprises insulating cardboards (1) and a plurality of insulating supporting strips (2), the insulating supporting strips are vertically arrayed, and the insulating cardboards are arranged among the insulating supporting strips; the insulating supporting strips are arrayed at equal intervals and adhered onto the insulting cardboards; and the insulating supporting strips are arranged at the edges of the insulating cardboards. The iron core oil passage structure has the advantages that the structure is convenient to produce and simple; the cooling problem of an iron core is effectively solved, and insulating performance of the transformer iron core can be effectively improved; and deformation caused by temperature change during application is reduced, and mechanical strength of the iron core is effectively increased.
Description
Technical field
The utility model relates to a kind of oil channel structure unshakable in one's determination of high-power transformer, belongs to the transformer technology field.
Background technology
At present, in high-power transformer, in order to prevent the local overheating that produces unshakable in one's determination, usually to cooling oil duct be set in inside unshakable in one's determination, coolant be introduced unshakable in one's determination interior to improve heat dispersion unshakable in one's determination.There are the following problems for the cooling oil duct of background technology: be difficult for processing, complex structure affect the insulation property of transformer core, in use because variations in temperature easily causes distortion, the bad mechanical strength of iron core.
The utility model content
The utility model purpose is to provide a kind of oil channel structure unshakable in one's determination of high-power transformer, and easily processing, simple in structure.Can effectively improve simultaneously the insulation property of transformer core at improvement heat dispersion unshakable in one's determination, reduce the distortion that causes because of variations in temperature in using, effectively raise mechanical strength unshakable in one's determination, the problems referred to above that the solution background technology exists.
The technical solution of the utility model is: a kind of oil channel structure unshakable in one's determination of high-power transformer, comprise insulating board, insulating stay, and some eradication edge stay longitudinal arrangements are arranged, insulating board are set between insulating stay; The mutual equidistant arrangement of described insulating stay is bonded on insulating board.
Insulating stay is arranged will guarantee the unimpeded of oil circuit, and the edge of insulating board arranges insulating stay.
Described insulating stay is the insulating stay that the environment-friendly type glass fiber reinforced unsaturated polyester plastic is made, and thickness is that 5 millimeters, width are 12 millimeters.The thickness of described oil duct unshakable in one's determination is 6 millimeters.
The utility model is suitable to be adopted on the iron core of three-phase and five-pole high-power transformer.
The utility model beneficial effect is: easily manufactured, simple in structure, when effectively solving heat dissipation problem unshakable in one's determination, can effectively improve the insulation property of transformer core, reduce the distortion that causes because of variations in temperature in using, effectively raise mechanical strength unshakable in one's determination.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram;
Fig. 2 is the utility model embodiment schematic side view;
In figure: insulating board 1, insulating stay 2.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described further.
A kind of oil channel structure unshakable in one's determination of high-power transformer comprises insulating board 1, insulating stay 2, and some eradication edge stay longitudinal arrangements are arranged, insulating board is set between insulating stay; The mutual equidistant arrangement of described insulating stay is bonded on insulating board.
Insulating stay is arranged will guarantee the unimpeded of oil circuit, and the edge of insulating board arranges insulating stay.
Described insulating stay is the insulating stay that the environment-friendly type glass fiber reinforced unsaturated polyester plastic is made, and thickness is that 5 millimeters, width are 12 millimeters.The thickness of described oil duct unshakable in one's determination is 6 millimeters.
The environment-friendly type glass fiber reinforced unsaturated polyester plastic has the good insulation characteristic, lower shrinkage and water absorption, and it is high, easily and the characteristics such as insulating board is bonding to have mechanical strength, the oil duct unshakable in one's determination of making can effectively improve the insulation property of transformer core when improving heat dispersion unshakable in one's determination, reduce the distortion that causes because of variations in temperature in using, effectively raise mechanical strength unshakable in one's determination.
