Abstract
The invention discloses a kind of production methods of transformer coil insulated cushion block, comprising the following steps: S1: production molding oxhorn cushion block forms oxhorn cushion block using machine tooling；S2: increasing insulation filler strip, will insulate filler strip using crimped paper or the rope made of hemp and molding oxhorn cushion block is bundled into an entirety；S3: binding and fixing, the filler strip that will insulate in S2 wrap together with the conducting wire for forming entirety and coil that oxhorn cushion block is bundled into.The present invention be combined with each other machining with hand-made, and it is closer in conjunction with coil transposition to make oxhorn cushion block, to achieve the purpose that improve transformer anti-short circuit capability.
Description
Technical field
The present invention relates to used in transformer coil cross-over block fields, specifically, are related to a kind of transformer coil insulated pad
The production method of block.
Background technique
At this stage, used in transformer coil oxhorn cushion block has machine tooling and hand-made two methods, the pad of machine tooling
Block, mechanical strength is good, but because of the relationship of coil winding technique, oxhorn cushion block defective tightness in conjunction with coil；Hand-made ox
Angle cushion block is closer in conjunction with coil, but its mechanical strength is bad.It is unfavorable for the short-circuit capacity of transformer.
Summary of the invention
To overcome the shortcomings of the above technical problem, will be machined and hand-made mutual knot the present invention provides a kind of
It closes, keeps oxhorn cushion block closer in conjunction with coil transposition, to reach the transformer wire for improving transformer anti-short circuit capability purpose
The production method for enclosing cross-over block.
The present invention is achieved through the following technical solutions:
A kind of production method of transformer coil insulated cushion block, comprising the following steps:
S1: production molding oxhorn cushion block forms oxhorn cushion block using machine tooling；
S2: increasing insulation filler strip, will insulate filler strip using crimped paper or the rope made of hemp and molding oxhorn cushion block is bundled into an entirety；
S3: binding and fixing, the filler strip that will insulate in S2 wrap together with the conducting wire for forming entirety and coil that oxhorn cushion block is bundled into.
Preferably, the edge chamfering polishing that oxhorn cushion block is formed in S1 is round and smooth.
Preferably, the molding oxhorn cushion block of machine tooling is put into coil transposition proportion in S2, according to molding oxhorn pad
The gap size of block and coil transposition increases insulation filler strip.
The beneficial effects of the present invention are: the present invention be combined with each other machining with hand-made, make oxhorn cushion block and line
Enclose transposition combine it is closer, thus achieve the purpose that improve transformer anti-short circuit capability.
Detailed description of the invention
The present invention will be further explained below with reference to the attached drawings.
Fig. 1 is the structural schematic diagram of mach molding oxhorn cushion block.
Fig. 2 is the structural schematic diagram for being bundled into integrated insulation filler strip and oxhorn cushion block.
Fig. 3 is the structural schematic diagram of filler strip and oxhorn cushion block with coil wrapping together that insulate.
In figure, 1 one-tenth new oxhorn cushion block, 2 insulation filler strips, 3 winding wires.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of production method of transformer coil insulated cushion block, comprising the following steps:
Step 1: according to drawing with machine tooling form oxhorn cushion block (such as Fig. 1), with machine tooling go out meet drawing requirement at
Type oxhorn cushion block pays attention to edge chamfering and polishes round and smooth.
Step 2: according to molding oxhorn cushion block, situation increases insulation filler strip (such as Fig. 2 shadow part in conjunction with coil transposition
Point), the molding oxhorn cushion block of machine tooling is put into coil transposition proportion, it is apertured in oxhorn cushion block and coil junction
Place is added suitable insulation filler strip, and will insulate filler strip with crimped paper and molding oxhorn cushion block is bundled into an entirety.Pay attention to wanting
Guarantee that insulation filler strip is tightly combined with the entirety that oxhorn cushion block is bundled into is formed with coil transposition.
Step 3: binding and fixing (such as Fig. 3) will insulate filler strip and molding oxhorn cushion block is bundled into crimped paper after an entirety
It not interrupt, take advantage of a situation and wrap the conducting wire of itself and coil together, guarantee that its is fixed.
The present invention be combined with each other machining with hand-made, keeps oxhorn cushion block closer in conjunction with coil transposition,
To achieve the purpose that improve transformer anti-short circuit capability.
