By such scheme, the circumferentially spaced arcuate groove that offers, arcuate groove up/down perforation on the porcelain bushing shell of described draw-in groove bottom；The centre bore of described pressing plate is shaggy tooth pore structure, and double wedge and arcuate groove stagger installation up and down.
By such scheme, the top of described conducting rod has spline towing pad.
By such scheme, described first sealing gasket is arranged in the internal cavities of porcelain bushing shell.
The beneficial effects of the utility model are: 1, use connecting bolt to hold out against fuel tank cap and strain porcelain bushing shell and be connected and sealed, connecting bolt and pressing plate are placed in the fuel tank internal of transformator, solve the problem that connector gets rusty in atmosphere due to exposure, the exposure that it also avoid sealing member is aging, indirectly improves the service life of transformator.2, the arcuate groove of porcelain bushing shell bottom and the double wedge of pressing plate stagger settings, can be prevented effectively from pressing plate loosening, come off from the bottom of porcelain bushing shell.3, this sleeve pipe is attractive in appearance, compact conformation, takes up room little.

Detailed description of the invention
In order to be more fully understood that this utility model, with specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.
A kind of novel transformer 6 ~ 35kV sleeve pipe as shown in Fig. 1 ~ 3, including conducting rod 6, porcelain bushing shell 1, connecting bolt 3 and the pressing plate 2 offering centre bore, conducting rod 6(is as shown in Figure 7) top be set with plain cushion 8, copper nut 9 and copper backing 12 successively, plain cushion 8 and the first sealing gasket 5 are compressed by copper nut 9 with porcelain bushing shell 1, as shown in Figure 9, first sealing gasket 5 is pearl shape sealing gasket, is arranged at the inside of porcelain bushing shell 1, prevents infrared ray radiation aging；The bottom of conducting rod 6 is inserted in the cavity within porcelain bushing shell 1, and the bottom of conducting rod is connected by going between to lift one's head with transformer coil；Fuel tank internal, through the fuel tank cap 11 of transformator, is inserted in the bottom of porcelain bushing shell 1；The middle and lower part of porcelain bushing shell 1 is provided with overhanging porcelain flange 1.1, the lower surface of overhanging porcelain flange 1.1 offers annular groove 1.5, annular groove 1.5 matches with the second sealing gasket 7, and the lower surface of overhanging porcelain flange 1.1 is by the second sealing gasket 7(as shown in Figure 8) it is close to the upper surface of fuel tank cap 11；The bottom of porcelain bushing shell 1 offers draw-in groove 1.2, is provided with cushion pad 4 in draw-in groove 1.2, and cushion pad 4 matches with the inside edge of pressing plate 2；Connecting bolt 3 is through pressing plate 2, and the upper end of connecting bolt 3 holds out against the lower surface of fuel tank cap 11, and now porcelain bushing shell 1 is strained with fuel tank cap 11, is tightly connected.
