Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 4, comprise upper clamping piece 6, arm-tie 7, insulating cement 8, lower clamping piece 10, wherein arm-tie 7 connects upper clamping piece 6 and lower clamping piece 10, transformer can be sling by arm-tie 7, upper clamping piece 6, lower clamping piece 10, the convenient installation and transportation, insulating cement 8 is because insulating cement has very strong fixed effect, iron core gravity is delivered on the lower clamping piece 10 by insulating cement 8, therefore can play the effect of supporting iron core well by insulating cement 8 lower clamping pieces 10.
The preferred 3M glue of insulating cement, 3M glue are a kind of insulating resins that solidifies at normal temperatures, the insulation property height, and the bonding strength height, coefficient of thermal expansion and contraction is little.
Folder processes with channel-section steel, is welded with band steel as support level, and opens corresponding fixing hole 13 on this folder, and fixing hole is used for installation and draws screw rod 11.
Utilize lower clamping piece 10 to support amorphous alloy iron core 9, can save the manufacturing materials of arm-tie, adopt the technical program that the intensity of arm-tie 7 is not had very high requirement simultaneously, arm-tie 7 can adopt common dry-type distribution transformer pulling plate structure, therefore can reduce the design and the Production Time of transformer.
As shown in Figure 5, described amorphous alloy iron core 9 is a three-phase three-column open coil iron core structure, and the cross section is a rectangle.
As shown in Figure 6, amorphous alloy iron core 9 epoxy coatings 14 surfaces scribble one deck insulating cement, lower clamping piece upper surface position insulating cement exceeds folder with iron core contact-making surface 10mm～15mm, the insulating cement thickness that the iron core upper surface is coated with is thinner than lower surface, in echelon, amorphous alloy iron core 9 upper surfaces can better be dispelled the heat, and the thickness of lower surface insulating cement is big, can play fixedly amorphous alloy iron core 9 better.
