Embodiment
The present invention is further elaborated below in conjunction with Figure of description.
The utility model amorphous alloy transformer integral type insulation system comprises that end insulation and the layer insulation of the low-voltage coil 3 of transformer are integrated bending structure; Main insulation 5 and the square ring of the high-tension coil 4 of transformer are structure as a whole; High-tension coil 4 closes around being an integral body with low-voltage coil 3.
As shown in Figure 1, in the present embodiment, the one bending structure adopts 0.08 glue-line insulating paper, by paper folder the end is folded to the thickness of one deck paper tinsel, and its layer insulation 1 and end insulation are integrated; The thickness a ÷ 0.08+1 of the height h+[low pressure Copper Foil 2 of the long L=low pressure of the expansion Copper Foil 2 of layer insulation 1] * end insulation height b, folded part is the end insulation of low-voltage coil 3, straight line portion is the layer insulation 1 of low-voltage coil 3, and layer insulation 1 is integrated with the end insulation, reduces the end distance of low-voltage coil 3.
As shown in Figure 2, distance between low-voltage coil 3 and the high-tension coil 4 is called master control road 7, master control road 7 is formed by several insulating papers system of enclosing, adopting 0.8 three thick board crimped papers near 2 integral type main insulation 5(present embodiments of high-tension coil 4) height lengthen, the length that lengthens is that the width of cloth of high-tension coil is to size, exceed the upper of high-tension coil 3, the bottom, elongated portion is as the high pressure square ring, exceed apart from the high pressure amplitude of length b=to+10, and exceed apart from length b to 15 ° ~ 50 ° angles of high-tension coil 4 sloped-end, present embodiment is 45° angle, making the high-tension coil internal oil channel is path, and namely main insulation and high pressure square ring are integrated, and increases high-tension coil 4 to the creep distance of low-voltage coil 3, shorten high-tension coil to the distance of iron yoke, play the effect of high-tension coil 4 square rings.
Low-voltage coil is the rectangle paper tinsel around, high-tension coil is rectangular layer around, the complete low-voltage coil of coiling, directly low-voltage coil is outside spread cardboard and crimped paper after, directly around high-tension coil (close around).
Shown in Fig. 3 ~ 5, after the low-voltage coil 3 coiling moulding, directly spread master control road 7 insulating papers, then the coiling high-tension coil 4, make low-voltage coil 3 and high-tension coil 4 form an integral body, again with amorphous iron core 6 suits, increase electric property and the mechanical performance of product.
