Be illustrated in figure 1 as amorphous alloy iron core dry distribution transformer core structural representation in the prior art, this transformer mainly is to adopt arm-tie to support the structure of iron core, and it is by amorphous alloy iron core 1, arm-tie bracing frame 2, and insulating cement 3, folder 4 draws screw rod 5 to form.Fig. 2, Fig. 3 are pulling plate structure figure, and the available technology adopting arm-tie supports amorphous alloy iron core, and arm-tie supports iron core; When lifting by crane transformer simultaneously, arm-tie connects upper clamping piece, lower clamping piece, and the material that uses when therefore making arm-tie is many, and high to the requirement of strength of arm-tie.
Not enough below prior art exists: 1. the transformer pulling plate size design time is long; 2. transformer pulling plate is made by the monoblock steel plate, and waste of material is more serious; When 3. transformer pulling plate was pieced together making by steel plate, difficult technique was accurate with the assurance size, and produced bigger noise.
Summary of the invention
The purpose of this invention is to provide a kind of dry-type distribution transformer that directly supports amorphous alloy iron core, can reduce design time, reduce material and manufacturing process requirement, and can reduce the noise that produces when transformer is worked with folder.
For realizing above purpose; Technical scheme of the present invention provides a kind of amorphous alloy dry-type transformer with folder support iron core, comprises upper clamping piece, lower clamping piece, arm-tie, insulating cement, draws screw rod, amorphous alloy iron core to be installed between upper clamping piece and the lower clamping piece; Arm-tie connects upper clamping piece and lower clamping piece; At the amorphous alloy core outer surface one deck epoxy coating is arranged, it is characterized in that, on epoxy coating, be coated with one deck insulating cement again; The insulating cement lower end is fixed on the lower clamping piece, and lower clamping piece supports amorphous alloy iron core through insulating cement.
Described insulating cement is the 3M insulating cement, and 3M glue is a kind of insulating resin that solidifies at normal temperatures, and insulation property are high, and bonding strength is high, and coefficient of thermal expansion and contraction is little.
Scribble the trapezoidal insulating cement of one deck on the epoxy coating surface.
Said lower clamping piece supports amorphous alloy iron core through insulating cement, and this iron core stress surface is big, be floated structure, and insulating cement exceeds lower clamping piece and follows amorphous alloy iron core contact-making surface 10mm～15mm in the upper surface position of lower clamping piece.
Described amorphous alloy iron core is a three-phase three-column open coil iron core structure, and the cross section is a rectangle.
Described folder processes with channel-section steel, is welded with band steel as support level, and on upper clamping piece, lower clamping piece, opens corresponding fixing hole.
The described screw rod that draws is a full flight screw.
Advantage of the present invention is: owing to adopt folder to support transformer core; Arm-tie is pressed the design of common transformer pulling plate structure; Therefore can reduce the design and the Production Time of amorphous alloy dry-type transformer in large quantities, the noise when having effectively reduced simultaneously the transformer operation to a certain extent.
