Wherein, what elastomeric element 5 adopted is O type sealing ring spring, is stuck in the endoporus of ring flange 4.
Have at least two screws 6 on ring flange 4, evenly to distribute.
Preferably, screw 6 is three.
Fixed part 1.2 is up big and down small, tapered shape.
Preferably, the cross section of groove 1.3 is square or rectangle.
Preferably, seal member 2 is sealing rings of oil resistant.
Another purpose of the present utility model provides a kind of single-phase pole type transformer, comprises the transformer body, and the bushing on the oil tank of transformer adopts the casing bit of above-mentioned single-phase pole type transformer.
Compared with prior art, the beneficial effects of the utility model are:
Contour structures is succinct, novel, has cancelled near the metal parts of sleeve pipe, defectives such as corrosion, peeling paint can not occur, overall appearance, and be convenient to install, improved operating efficiency, improved operating security reliability.

Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in detail.
As shown in Figure 1, the protector of the single-phase pole type transformer of the utility model comprises porcelain vase 1, sealing gasket 2 and ring flange 4, and porcelain vase 1 comprises protecting component 1.1, fixed part 1.2 and groove 1.3, and groove 1.3 is arranged between protecting component 1.1 and the fixed part 1.2.Groove 1.3 on the porcelain vase is square, and the fixed part 1.2 of porcelain vase is up big and down small, tapered shape, and fixed part 1.2 following little, easy when then inserting case lid hole 3.1, fixed part 1.2 top can prevent that greatly rainwater from bleeding in the fuel tank.When porcelain vase 1 penetrated the collar aperture 3.1 of transformer case lid 3, groove 1.3 was below transformer case lid 3, and elastomeric element 5 and ring flange 4 are inserted in from the fixed part 1.2 of porcelain vase respectively, and elastomeric element 5 is enclosed within on the groove 1.3.In the present embodiment, elastomeric element 5 is ring springs of O type sealing, ring flange 4 be arranged on transformer case lid 3 below, at least two screws 6 evenly distribute on ring flange 4, in the present embodiment, three screws 6 that diameter is 8mm evenly distribute on ring flange 4.Seal member 2 be arranged on transformer case lid 3 above, seal member 2 is sealing rings of oil resistant, porcelain vase 1 push down seal member 2 back be difficult for loosening, can not leakage of oil.
