Abstract
The utility model discloses a kind of U-shaped insulation pressing, comprise insulation pressing, in the middle of described insulation pressing, be provided with U-shaped groove, bottom portion of groove is provided with pad, and the utility model is simple for production, easy for installation, the positioning precision of coil and the overall mechanical strength of coil can be improved, coil can better be dispelled the heat.
Description
Technical field
The utility model relates to the technical field of the cross-over block of the end axial compression of transformer coil.
Background technology
The transformer coil of current production, for ensureing the electric clearance of coil and iron core, high-tension coil and low-voltage coil need to adopt more insulating materials in end; And also need layer insulation between high and low pressure coil, but overhang insulation use too much can affect coil heat radiation.
Utility model content
Utility model object: the problem affecting coil heat radiation for existing briquetting, the utility model provides a kind of U-shaped insulation pressing, simple for production, easy for installation, can improve the positioning precision of coil and the overall mechanical strength of coil, and coil can better be dispelled the heat.
Technical scheme: a kind of U-shaped insulation pressing, comprises insulation pressing, is provided with U-shaped groove in the middle of described insulation pressing.
Particularly, the material of described insulation pressing is pottery.
Particularly, described groove surfaces Non-smooth surface, with increasing friction force during placement high and low pressure coil.
Particularly, the length, width and height ratio of described insulation pressing is 7:2:4.
Particularly, the length of described insulation pressing is 7:1 with groove groove width ratio.
Particularly, the height of described insulation pressing is 7:1 with groove groove height ratio.
Particularly, described bottom portion of groove is provided with pad, prevents insulation pressing from rupturing.
Beneficial effect: compared with prior art, the U-shaped insulation pressing of the one that the utility model provides, groove is provided with in the middle of briquetting, when using insulating materials to compress high and low pressure coil and locate, groove can be utilized to place the layer insulation sheet of high and low pressure coil to increase the creep age distance between high-tension coil and low-voltage coil, and adopt U-shaped insulation pressing high and low pressure coil can be clamped, be convenient to be uniformly distributed the placement location between high and low pressure coil, reach and reduce the object that insulating materials uses increase radiating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
As shown in Figure 1-2, a kind of U-shaped insulation pressing, comprises insulation pressing 1, is provided with U-shaped groove in the middle of described insulation pressing 1, groove surfaces Non-smooth surface, increasing friction force, bottom portion of groove is provided with pad 2, prevents insulation pressing 1 from rupturing, the material of insulation pressing 1 is pottery, length, width and height ratio is 7:2:4, and the length of insulation pressing 1 is with groove groove width than being 7:1, and the height of insulation pressing 1 is 7:1 with groove groove height ratio.
Embodiment 1
A kind of U-shaped insulation pressing, add the appearance and size of man-hour according to U-shaped briquetting, process corresponding U-shaped mould, perfusion is mixed with the epoxy resin of filler and curing agent in a mold, by the bubble removal in resin after vibrations, then carry out hot setting, to be solidified shaping after open mould, or compressing in a mold with ceramic material, dry after depanning, then glazing, finally carries out high-temperature heating with high temperature furnace and forms by a firing, put into pad 2 at bottom portion of groove.
Embodiment 2
U-shaped insulation pressing adopts an insulating sheet material for thickness and groove same size, first cuts into the cuboid identical with insulation pressing 1 width, and then with a chainsaw according to the dimensioned of U-shaped briquetting.Due to the high temperature produced when processing cutting, easily destroying the insulating properties of insulating materials, needing to cool with water like this in the process of cutting.After machining, insulating materials is dried, remove the moisture of its inside, be coated with insulated paint, then dry, prevent insulating materials from absorbing moisture in air in use, thus have influence on the result of use of insulation pressing 1, finally put into pad 2 at bottom portion of groove.
The utility model can use on flameproof mining mobile transformer substation, and insulation pressing uses pottery or other insulating materials machine-shaping, has the characteristics such as non-conductive, nonhygroscopic.
