Abstract

The utility model is related to transformer technology fields, more particularly, to the insulation pressing structure of vertical wound core transformer, it include the coil of triangle arrangement, the upper end of coil is equipped with press strip and center pressing plate, press strip compresses the upper end of coil according to triangular arrangement, center pressing plate is equilateral triangle plate, and the triangle end of center pressing plate compresses the upper end of three coils, the lower pull rod of middle part connection of center pressing plate respectively;Three sides of the center pressing plate are equipped with concane gap, and three concane gaps are uniformly distributed around the center of center pressing plate, and the gap digit between the opening face difference coil of concane gap.The utility model is simple and reasonable for structure, optimizes the arrangement and structure of press strip and center pressing plate, can effectively solve the problem that the flow field problem of transformer oil, improve the service efficiency and service life of transformer.

Description

The insulation pressing structure of vertical wound core transformer
Technical field
The utility model is related to transformer technology field, knot is suppressed in the insulation more particularly, to vertical wound core transformer Structure.
Background technology
When vertical wound core transformer makes, it is typically necessary and coil is suppressed, but existing vertical wound core transformer Insulation pressing structure Shortcomings cannot fully meet transformer so that the flowing of transformer oil is very inconvenient after oil immersion Use demand, the effect of leading to transformer, are poor.
Invention content
The purpose of this utility model is to provide a kind of insulation pressing structures of vertical wound core transformer, optimize structure, Facilitate installation, stable structure, the good fluidity of transformer oil.
In order to achieve the above objectives, the utility model adopts the following technical solution:
The insulation pressing structure of vertical wound core transformer, includes the coil of triangle arrangement, and the upper end of coil is equipped with pressure Item and center pressing plate, press strip compress the upper end of coil according to triangular arrangement, and center pressing plate is equilateral triangle plate, center pressing plate Triangle end compress the upper ends of three coils, the lower pull rod of middle part connection of center pressing plate respectively;Three sides of the center pressing plate It is equipped with concane gap, three concane gaps are uniformly distributed around the center of center pressing plate, and between the opening face difference coil of concane gap Gap digit.
Said program is further:Cushion block is equipped on the downside of the press strip between coil, cushion block surrounds in the pressing plate of center The heart is uniformly distributed.
Said program is further:The concane gap is U-shaped, C-shaped or bracket.
The utility model is simple and reasonable for structure, optimizes the arrangement and structure of press strip and center pressing plate, can effectively solve the problem that change The flow field problem of depressor oil improves the service efficiency and service life of transformer.
Description of the drawings:
Attached drawing 1 is the utility model one example structure schematic diagram.
Specific implementation mode:
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing It is bright, to be fully understood from the purpose of this utility model, feature and effect.
As shown in fig.1, being the utility model preferred embodiment structural schematic diagram, the utility model is in relation to a kind of vertical volume The insulation pressing structure of appendiron core transformer includes the coil 1 of triangle arrangement, and coil 1 is according to needing to be wrapped on iron core, coil 1 upper end is equipped with press strip 2 and center pressing plate 3, and in practice, press strip 2 and center pressing plate 3 can be symmetricly set on the upper and lower side of coil 1 (1 upper end press strip 2 of coil and center pressing plate 3 are only shown in figure), concrete structure is according to needing to arrange.Shown in Fig. 1, press strip 2 according to Triangular arrangement compresses the upper end of coil 1, and for that can increase pressing force, cushion block 5, cushion block 5 are equipped between 2 downside of press strip and coil 1 It is designed according to the shape at support pad position, has spacing between cushion block 5.Center pressing plate 3 be equilateral triangle plate, the three of center pressing plate 3 Angle end compresses the upper end of three coils 1, pull rod 4 under the middle part connection of center pressing plate 3 respectively;Three sides of the center pressing plate 3 It is equipped with concane gap 31, three concane gaps 31 are uniformly distributed around the center of center pressing plate 3, and the opening face of concane gap 31 is not collinear Gap digit between circle 1.In the present embodiment, the shape of concane gap 31 can be U-shaped, C-shaped or bracket, and cushion block 5 surrounds center The center of pressing plate 3 is uniformly distributed.
The utility model is simple and reasonable for structure, optimizes the arrangement and structure of press strip 2 and center pressing plate 3, center pressing plate 3 Three sides are equipped with concane gap 31, and three concane gaps 31 are uniformly distributed around the center of center pressing plate 3, and the opening face of concane gap 31 Gap digit between different coils 1, which not only ensure that the structural and press power of center pressing plate 3, and concane gap 31 rises To ventilative, the transformer oil flowing in the middle part of promotion transformer.It is equipped with cushion block 5 between the downside of press strip 2 and coil 1, cushion block 5 is according to holding The shape design at position is padded, has spacing between cushion block 5, equally can effectively solve the flow field problem of transformer oil, improve transformation The service efficiency and service life of device, the use of transformer are safer.
The utility model is elaborated above in association with embodiment, is only the technical concept for illustrating the utility model And feature can not be with this its object is to allow person skilled in the art to understand the content of the utility model and be implemented Restriction the scope of protection of the utility model, therefore all equivalent change or modifications substantially done according to the spirit of the present invention, are all answered Cover within the protection scope of the present utility model.
