Abstract
The utility model belongs to the technical field of an amorphous alloy transformer, in particular to a coil end face support structure for an amorphous alloy transformer, comprising a cushion block arranged on the coil end face of the amorphous alloy transformer, wherein the cushion block is an insulating cushion block; a hard end ring is arranged on a low voltage coil end face of the amorphous alloy transformer; the hard end ring is an annular structure provided with an opening. The coil end face support structure for the amorphous alloy transformer has advantages that the cushion block is of electrical insulating laminated wood or laminated paper board material, and the support area is large, and the style is comparatively simple, and the material use ratio is high. The coil end face support structure for the amorphous alloy transformer has excellent insulating property and excellent hardness, which ensure that the coils are not deformed when the amorphous alloy transformer is impacted by the overcurrent or overvoltage.
Description
Technical field
The utility model belongs to amorphous alloy transformer technical field field, a kind of specifically amorphous alloy transformer coil end face supporting construction.
Background technology
What mostly existing transformer coil end washers block structure was employing is that wood block filler adds the cushion block structure that insulating electrical cardboard bonding is formed, and the material of wood block filler is a Manchurian ash, and Area of bearing is little; Pattern is complicated, and manufacturing procedure is more, and stock utilization is lower; Principal element wherein is the lines that the wood materials selection will be considered timber; Could guarantee that its hardness is higher relatively, but the insulation property of wood materials and hardness are not strong, can not guarantee the impact resistance that coil is enough.Existing 315kV and following transformer support with four cushion blocks along the coil circumference, 400kV and abovely adopt Zhi Tie and cross-over block to unite support along the coil circumference.315kV and following transformer, because Capacity Ratio is less, coil is less, supports with four cushion blocks and can satisfy technological requirement.Cushion block support can only support coils the part end face, the protection to coil when coil receives short-circuit impact is not enough.400KVA and above transformer capacity are bigger, and coil is bigger, unite support with Zhi Tie and cross-over block, and the supporting surface of coil can increase, and have protected transformer coil effectively.Welding iron has increased workman's workload on folder, and an iron of welding can not guarantee with the folder channel-section steel in one plane, brought inconvenience to assembling.Low-voltage coil end wire turn is evened up, and fill with lines in the prismatic district, has vacant position, and does not support entirely.The weak point of said structure is: every coiling one deck copper cash all will be evened up the end wire turn, has increased workload, and technique for coiling is complicated, and technique controlling difficulty is bigger, can not effectively guarantee the overall dimension of coil.When the wire turn room generally having occurred, all take to be cut into prismatic with electrician's insulating board, the room size the when length of prismatic, width and thickness are evened up by the lead wire turn is configured, fills.
Like the patent No. is 200720040420.8; The applying date is 2007-07-27; Name is called the utility model patent of " the mold pressing cushion block of transformer coil "; Its technical scheme is: a kind of mold pressing cushion block of transformer coil, and the end of mold pressing cushion block and horizontal tail stay are suitable, and the thickness of mold pressing cushion block is 5mm and by unsaturated polyester material mold pressing one-time cast-forming.The utility model uses thickness to replace original cushion block as the mold pressing cushion block of 5mm, but the cushion block after improving still can not be applicable to the transformer capacity that 400KV is above.
Summary of the invention
Because existing transformer supporting construction exists insulation property and hardness not strong; Can not guarantee the problem of the impact resistance that coil is enough; Special a kind of insulation property and the hardness height of proposing; Guaranteed amorphous alloy transformer when receiving the impact of overcurrent or overvoltage, the indeformable amorphous alloy transformer coil end face of coil supporting construction, its technical scheme is following:
A kind of amorphous alloy transformer coil end face supporting construction; Comprise the cushion block that is arranged on amorphous alloy transformer insulated coil end face; It is characterized in that: said cushion block is a cross-over block; Amorphous alloy transformer low-voltage coil end face is provided with hard end circle, and said hard end circle is a circulus, and ring-type is provided with opening.
Said cross-over block is laminated paper board or lamination wood.
Said hard end circle opening two ends height is different.
Said hard end circle is an epoxy glass fabric.
The advantage of the utility model is:
1, the amorphous alloy transformer coil end face all is to adopt cushion block to support, and cushion block is selected electric insulation lamination wood or laminated paper board material for use, and Area of bearing is big, and pattern is simple relatively, and stock utilization is high.Superior insulation property and hardness have guaranteed amorphous alloy transformer when receiving the impact of overcurrent or overvoltage, and coil is indeformable.
2, amorphous alloy transformer only need support the transformer both direction, so do not need gusset, structure is simpler.
3, hard end circle processes separately, and material is an epoxy glass fabric, and hardness is higher, so do not need the coil-end wire turn to even up.The end insulation is used for filling and leading up the spiral end face of winding, improves the mechanical stability of winding overhang.Because hard end circle is to make according to the end surface shape of coil, thus can accomplish and coil between do not have the gap.
4, the different axial mechanical strengths that strengthened coil on amorphous alloy transformer coil end face supporting construction and the material, the coiling process is more convenient.

Embodiment
Amorphous alloy transformer coil end face supporting construction; Comprise the cushion block that is arranged on amorphous alloy transformer insulated coil end face, said cushion block is a cross-over block, and amorphous alloy transformer low-voltage coil end face is provided with hard end circle; Said hard end circle is a circulus, and ring-type is provided with opening.Said cross-over block is laminated paper board or lamination wood.Said hard end circle opening two ends height is different.Said hard end circle is for being epoxy glass fabric.
The amorphous alloy transformer coil end face all is to adopt cushion block to support, and cushion block is selected electric insulation pressed laminated wood material for use, and Area of bearing is big, and pattern is simple relatively, and stock utilization is high.Superior insulation property and hardness have guaranteed amorphous alloy transformer when receiving the impact of overcurrent or overvoltage, and coil is indeformable.
The coil two ends all use cross-over block (laminated paper board or lamination wood) to support, and have cancelled gusset.The folder of amorphous alloy transformer and existing transformer folder have very big difference, and the change of folder makes the cushion block position of amorphous alloy transformer that change take place.Amorphous alloy transformer only need support the transformer both direction, so do not need gusset, structure is simpler.Low-voltage coil is the relatively low coil of voltage in the transformer coil.Because generally all higher pressure is much bigger for the low-voltage coil electric current, for guaranteeing current density, its used lead is all bigger, and the number of turn is few, in order to increase the axial strength of coil, so need the end circle.Hard end circle processes separately, and material is an epoxy glass fabric, and hardness is higher, so do not need the coil-end wire turn to even up.The end insulation is used for filling and leading up the spiral end face of winding, improves the mechanical stability of winding overhang.Because hard end circle is to make according to the end surface shape of coil, thus can accomplish and coil between do not have the gap.
