In one groove and the second groove, for the head and end of insulation board is glued respectively to the first groove and second
In groove.
Also include that electrical adhesive tape, described electrical adhesive tape are wrapped in the outer peripheral face of cylindric insulation board.
Described electrical adhesive tape is respectively being wound around a circle at the upper surface and lower surface of described insulating cylinder.
Described insulation board is rectangle insulant.
Described insulation board is flexible epoxy glass fiber plate or mylar composite brattice.
The width of described insulation board is identical with described flat mouth stay length.
Described flat mouth stay uses glass fiber reinforced polyester resin to make.
The degree of depth of described first groove and the second groove is 10mm, and width is 1.5mm.
This utility model uses as above technical scheme, offers the first groove on the dual-side of flat mouth stay
With the second groove；The head end of described insulation board is inserted in the first groove on described flat mouth stay, described
The end of insulation board inserts in the second groove on described flat mouth stay, and this utility model passes through flat mouth stay
Connection to make insulating cylinder take mouth more firm, succinctly, more more attractive.
Efficiently solve the problem that the insulation of insulation board lap-joint is weak and is easily deformed, and overcome transformation
Easily there is phenomenon of coming unglued in the vibrations of device longtime running, and effectively reduce the noise produced because of resonance.

Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2 and Figure 4, this utility model provides a kind of dry-type transformer insulating cylinder, should
Insulating cylinder is arranged between dry-type transformer high-low pressure winding, including insulation board 1, flat mouth stay 2 and epoxy
Resin；The first groove 3 and the second groove 4 is offered on the dual-side of described flat mouth stay 2；Described insulation
Plate 1 bends to cylindrical shape, and the head end of described insulation board 1 inserts the first groove 3 on described flat mouth stay 2
In, the end of described insulation board 1 inserts in the second groove 4 on described flat mouth stay 2；Described epoxy
Resin spreads upon in described first groove 3 and the second groove 4, for being divided by the head and end of insulation board 1
It is not bonded in the first groove 3 and the second groove 4.Described first groove 3 and the degree of depth of the second groove 4
Being 10mm, width is 1.5mm.
This utility model uses as above technical scheme, offers first recessed on the dual-side of flat mouth stay 2
Groove 3 and the second groove 4；The head end of described insulation board 1 is inserted the first groove on described flat mouth stay 2
In 3, the end of described insulation board 1 inserts in the second groove 4 on described flat mouth stay 2, and this practicality is new
It is more firm that type makes insulating cylinder take mouth by the connection of flat mouth stay 2, succinctly, more more attractive.Effectively solve
The insulation of insulation board 1 lap-joint is weak and the problem that is easily deformed, and overcomes transformator longtime running
Easily there is phenomenon of coming unglued in vibrations, and effectively reduce the noise produced because of resonance.
