Description
Technical field
The utility model is related to a kind of insulating parts, and in particular to a kind of oil-immersed transformer insulating oil duct.
Background technology
In existing oil-immersed transformer, the corrugated board of the usually used insulation of high-low pressure winding isolation, but this corrugation
The oil duct narrower width that cardboard is formed, heat dissipation effect are poor；And when transformer oil passage insulating part is pressed on cross-over block, it is easy
Oil duct is caused to block or cave in, transformer oil can not circulate, and then the coil temperature at the oil duct is made to increase, and be easy to happen coil
The phenomenon that burning；And the corrugated board of this insulation is generally made of A class F insulating material Fs, and heat resisting temperature is 105 °, works as temperature
When spending high, corrugated board meeting accelerated ageing is even breakdown, so as to cause oil-immersed transformer in the feelings for occasionally having overlond running
Security risk is generated under condition.
Utility model content
The utility model is intended to provide that a kind of oil duct is broad, is not easy to cave in or be blocked, and local coil overheat is avoided to burn,
Rate of heat dissipation is high；And section components processing cost is low；It still can guarantee the circulation heat dissipation of transformer oil when certain oil circuit be collapsed；It is resistance to
Hot temperature is high, and the oil-immersed transformer insulating oil duct of security risk will not occur in the case where occasionally having overlond running.
A kind of oil-immersed transformer insulating oil duct in this programme, including insulating paper strip and multiple be distributed on insulating paper strip
Support element, the support element connect with insulating paper strip by adhesive, and the support element includes braced wing and multiple along support
The uniformly distributed cushion block of part length direction, the cushion block interlaced arrangement of each adjacent two support element；The cushion block end face and insulating paper strip
Fixed, other end is fixed with braced wing；The braced wing includes the fagging of integrated bending forming and the support positioned at fagging both sides
Frame, the fagging and insulating board are horizontally disposed, and the angle of support and fagging is 65 °~70 °, the free end of support and cushion block
Side wall offsets；The distance between two neighboring support element is 20mm~25mm, pad thickness 3.5mm；The insulating paper strip is adopted
With F class F insulating material Fs, braced wing and cushion block use H grades of solid insulating materials.
The utility model has the advantages that：1, due to increasing support wing structure, by pressure dissipation, insulating oil duct is made to be not easy to collapse
It collapses, so as in the case where ensureing that the oil circuit of insulating oil duct is unimpeded, increase the distance between support element, broadening oil circuit accelerates heat dissipation effect
Rate；2, since cushion block has multiple, the interval between cushion block can prevent whole oil duct to be totally blocked, and local coil is avoided to overheat
The case where burning hair occurs；3, it also is available for transformer oil flowing between the support and cushion block of braced wing, further widens oil circuit, carries
High 15% rate of heat dissipation, if while oil circuit cave in, cushion block side, support and part fagging formed stable section be triangle
The oil circuit of shape makes transformer oil that can still circulate heat dissipation；4, it due to cushion block small volume, can be used remaining after braced wing processing
Expect machine-shaping, saves material, environmental protection and reduction processing cost；5, since insulating paper strip uses F class F insulating material Fs, heat-resisting temperature
Degree is 155 °, and using H grades of solid insulating materials, heat resisting temperature is 180 °, prevents insulating materials because of transformer for braced wing and cushion block
Overlond running and temperature raising cause its accelerated ageing even it is breakdown, prevent peak period when security risk.
Further, it is uniformly provided with strip through-hole on the support, makes to be connected between two neighboring oil duct, prevents certain section of oil circuit
Heat dissipation is influenced after blocking.
Further, the insulating paper strip uses water chestnut lattice gluing insulating paper.
Further, the braced wing and cushion block are all made of aromatic polyamide paper.
Further, the braced wing and cushion block use precompressed densification process, to improve its intensity.

Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments：
According to Fig. 1 to 3, a kind of oil-immersed transformer insulating oil duct, including insulating paper strip 1 and multiple it is distributed on insulation
Support element 2 on paper tape 1.Support element 2 includes braced wing and multiple cushion blocks 23 uniformly distributed along 2 length direction of support element, per adjacent
23 interlaced arrangement of cushion block of two support elements 2.The clout processing after braced wing processing can be used in the cushion block 23 of this small volume
Molding, saves material.23 end face of cushion block is connected and fixed with 1 adhesive of insulating paper strip, and other end passes through glue with braced wing
Stick connects.Braced wing includes the fagging 21 of integrated bending forming and the support 22 positioned at 21 both sides of fagging, fagging 21 and insulation
Cardboard is horizontally disposed, and support 22 and the angle of fagging 21 are 65 °, and the free end of support 22 and the side wall of cushion block 23 offset.Fagging
Pressure dissipation can be increased the distance between support element 2, keeps oil circuit wider and be not easy the obstruction that caves in by 21.
As shown in figure 3, if oil circuit caves in, 23 side of cushion block, support 22 can form stabilization in turn with part fagging 21
Section be triangle oil circuit 4, fagging 21 after by the power of arrow direction at this time, at this time by the main stress in 23 side of cushion block, from
And the oil circuit 4 for avoiding triangle occurs secondary blocking or caves in, and ensures the circulation heat dissipation of transformer oil.It is two neighboring in order to make
It is connected between oil duct, influences heat dissipation after preventing certain section of oil circuit from blocking, strip through-hole 3 is uniformly provided on support 22.It is two neighboring
The distance between support element 2 is 23mm, and 23 thickness of cushion block is 3.5mm.Insulating paper strip 1 uses water chestnut lattice gluing insulating paper, heat-resisting temperature
Degree is 155 °.Braced wing uses the aromatic polyamide paper of H grades of solid insulating materials, and precompressed densification process, strong to improve it
Degree.
