Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Oil immersed type transformer with amorphous alloy made iron core as shown in Fig. 7-Figure 13, comprises 3 coils, 1,8 iron cores 2 and cover plate 3,
It is matrix pattern that the inwall of 3 coils 1 is provided with the vertical view of insulation 4,3, cylinder insulation cylinder 4, and coil 1 is closely wound on the outer side of insulation cylinder 4;
A compression bar 5 it is provided with in the middle part of the bottom surface of cover plate 3;
3 coils 1 are arranged in order, and adjacent coil 1 leaves gap;
First iron core 2-1 coiling is through the left back through hole of the first insulation cylinder 4-1, 2nd iron core 2-2 coiling is through the left front through hole of the first insulation cylinder 4-1, the right back through hole of the first insulation cylinder 4-1 and the left back through hole of the 2nd insulation cylinder 4-2 are passed in 3rd iron core 2-3 coiling, the right front through hole of the first insulation cylinder 4-1 and the left front through hole of the 2nd insulation cylinder 4-2 are passed in 4th iron core 2-4 coiling, the right back through hole of the 2nd insulation cylinder 4-2 and the left back through hole of the 3rd insulation cylinder 4-3 are passed in 5th iron core 2-5 coiling, the right front through hole of the 2nd insulation cylinder 4-2 and the left front through hole of the 3rd insulation cylinder 4-3 are passed in 6th iron core 2-6 coiling, 7th iron core 2-7 coiling is through the right back through hole of the 3rd insulation cylinder 4-3, 8th iron core 2-8 coiling is through the right front through hole of the 3rd insulation cylinder 4-3,
All leave gap between iron core 2 and insulation cylinder 4, between adjacent iron cores 2, also leave gap;
The gap that the compression bar 5 of cover plate 3 passes front two rows iron core 2 is pressed in the middle part of 3 coils 1.
One, the insulation cylinder of prior art and insulation cylinder of the present utility model, contrast as follows:
1, as shown in figures 1 and 3, when transformer normal operation, coil a is out of shape extruding insulation cylinder b, and insulation cylinder b produces microdeformation, does not affect iron core c. When there is single-phase short circuit in transformer, coil a shrinks extruding insulation cylinder b, insulation cylinder b is out of shape bigger, its stressing conditions is as shown in Figure 2, insulation cylinder b surrounding central point is the weakest, when distortion amount exceedes the space between insulation cylinder b and iron core c, and extruding iron core c, iron core c is out of shape, and the zero load of transformer sharply increases.
2, as shown in figures 7 and 9, the utility model adds " ten " word fagging in the centre of insulation cylinder 4, the vertical view of insulation cylinder 4 is matrix pattern, major part force localization is on middle cross fagging, bending resistance originally is changed into crush resistance, the crush resistance of same material is far longer than bending resistance, and its stressing conditions is as shown in Figure 8.

Through test, the non-deformability of insulation cylinder of the present utility model, is equivalent to the non-deformability of 3.5 times of thickness of existing insulation cylinder.
Two, the change of the utility model insulating barrel structure, brings " simplification pressing plate " and " reduces iron core
Highly " two unexpected technique effects:
(1), " simplification pressing plate "
1, as shown in Fig. 3,4,5,6, all not having gap between existing transformer 8 iron cores, the both sides of coil and middle part can only be compressed by cover plate e by pressing plate d, if not having pressing plate d, then cannot be compressed at the middle part of coil a.
2, as shown in Fig. 9,10,11,12,13, insulation cylinder 4 center is cruciform, gap is all left between iron core 2 and insulation cylinder 4, also gap is left between adjacent iron cores 2, the compression bar 5 of cover plate 3 can be pressed in the middle part of 3 coils 1 through the gap of front two rows iron core 2, the two ends of iron core 2 are directly compressed by cover plate 3, simplify compressing structure, it is not necessary to arrange pressing plate.
(2), " iron core height is reduced "
1, as shown in Figure 3, owing to have employed pressing plate d, the height of iron core c must increase, and for pressing plate d reserves through the space with placement, because this increasing the material of iron core c, adds cost, the volume and weight of transformer.
2, as shown in Figure 9, owing to the utility model is without the need to arranging pressing plate, the height of iron core 2 can reduce, and therefore reduces the material of iron core 2, reduces the cost of transformer, reduces volume and weight.
Above-mentioned preferably implement mode for the utility model; but enforcement mode of the present utility model is not by the restriction of foregoing; change that other any does under not deviating from spirit of the present utility model and principle, modification, replacement, combination, simplification; all should be the substitute mode of equivalence, it is included within protection domain of the present utility model.
