Description
Technical Field
The utility model relates to a power equipment field, in particular to novel oil duct of transformer.
Background
In the operation process of the transformer, the winding generates heat, the larger the capacity of the transformer is, the larger the heat generated by the transformer is, the oil duct is needed to take away the heat of the winding, and therefore the heat dissipation performance of the oil duct is of great importance to the safe operation of the transformer. For a transformer using a layered or foil coil, a conventional oil duct is formed by arranging straight bar-shaped supporting bars at intervals, and the heat dissipation performance of the oil duct and the mechanical strength of the coil are affected by the small distance between the supporting bars. The brace has good heat dissipation effect but low mechanical strength if the distance between the braces is large; the small interval of the stay is poor in heat dissipation effect but good in mechanical strength, so that the stay is difficult to meet the requirements of mechanical strength and heat dissipation effect at the same time.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve one of the technical problem that exists among the prior art at least, provide a novel oil duct of transformer, can make the transformer of using laminar or foil coil have better radiating effect and mechanical strength.
The utility model discloses a first aspect provides a novel oil duct of transformer, include: the glue dispensing paper comprises glue dispensing paper, wherein a plurality of rows of cushion blocks are arranged on the surface of the glue dispensing paper, each cushion block comprises at least 2 cushion blocks, and the cushion blocks of two adjacent rows of cushion blocks are distributed in a staggered mode.
Furthermore, the cushion blocks in the cushion block group are distributed at equal intervals.
Further, the cushion block is made of a paperboard.
Furthermore, the plurality of rows of cushion blocks are distributed on the surface of the adhesive dispensing paper at equal intervals.
The novel oil duct of transformer that above-mentioned technical scheme provided has following beneficial effect at least: the utility model provides a novel oil duct of transformer, through setting up a plurality of line backing block groups on some adhesive tape, the cushion in two adjacent line backing block groups is crisscross to be distributed, can provide the structural foundation for realizing crooked oil stream in the transformer, makes the coil heat dissipation of transformer more even, reduces the hot point temperature rise of coil; in addition, the adhesive dispensing paper can be solidified when the transformer is dried, so that the bonding force between the cushion block and the coil is enhanced, the mechanical strength is increased, and the mechanical strength is ensured when a better heat dissipation effect is realized.

If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.
Referring to fig. 1 and 2, an embodiment of the present invention provides a novel oil duct of a transformer, including: the adhesive tape dispensing device comprises adhesive tape dispensing paper 2, wherein a plurality of rows of cushion blocks 3 are arranged on the surface of the adhesive tape dispensing paper 2, each cushion block comprises at least 2 cushion blocks 1, and the cushion blocks 1 of the two adjacent rows of cushion blocks 3 are distributed in a staggered mode.
It should be noted that the number of the cushion blocks 3 is adjusted according to the height of the coil, and the coil can be covered as a whole, which is not described herein again. It can be understood that the specific number, length, and width of the cushion blocks 1 are adjusted by the height required by the oil passage and the diameter of the coil where the oil passage is located, and the coil can be entirely coated after the cushion block group 3 is formed, which is not described herein again. It should be noted that, the cushion blocks 1 of two adjacent rows of cushion block groups 3 are preferably distributed in a staggered manner in this embodiment, so that oil can form a curved oil flow when passing through the cushion blocks 1, thereby achieving a better heat dissipation effect. It should be noted that, in order to achieve a better oil flow trajectory, the lower side of the upper cushion block group 3 and the upper side of the lower cushion block group 3 are preferably located on the same plane, and based on such a structure, the oil cannot flow linearly, so that the oil flow is ensured to be curved, and a better oil flow effect is ensured.
Further, in another embodiment of the present invention, the cushion blocks 1 in the cushion block group 3 are distributed equidistantly.
Wherein, it should be noted that, the equidistance distribution of cushion 1 is only this embodiment's preferred, can make the oil stream more even to make the heat dissipation of coil point more even, if can also set up to non-equidistance distribution for special heat dissipation requirement, concrete setting mode according to actual demand adjustment can. It will be appreciated that for the above reasons, the cushion blocks 1 in the cushion block group 3 are the same in size and arrangement direction, and will not be described in detail herein.
Further, in another embodiment of the present invention, the cushion block 1 is made of cardboard.
It should be noted that, the cushion block 1 is formed by pressing a paperboard, which is only preferred in this embodiment, so that a good heat dissipation effect can be ensured, the manufacturing cost of the paperboard is low, cushion blocks obtained by other materials and manufacturing methods can be adopted according to actual requirements, and the specific material of the cushion block 1 can be adjusted according to the actual requirements for heat dissipation.
Further, in another embodiment of the present invention, the plurality of row cushion blocks 3 are distributed on the surface of the dispensing paper 2 at equal intervals.
