Abstract
The invention provides a sealing device for an oil-immersed fuse pedestal. The fuse pedestal is arranged on a transformer box and comprises a pedestal base and a pedestal shell; the sealing device comprises a fastener and a seal ring; and the fastener is arranged on the pedestal base of the fuse; the seal ring is arranged at the root of the fuse pedestal; and the sectional shape of the seal ring is a circle and a lip integrated with the circle. The sealing device has multiple-seal protection characteristic, ensures reliable sealing property due to the double static sealing of the end face and the radial direction, can effectively prevent invalidation of the seal ring due to misplaced shearing and has the double-seal effect for isolating the transformer oil from the root of the pedestal as well as the static seal part of the end face and the multiple-seal protection for the damageable root of the pedestal.
Description
Technical field
The present invention relates to a kind of sealing device that is used for oil-immersed fuse pedestal.
Background technology
The oil-filled transformer case becomes uses fuse; Generally need to adopt conventional seal washer as sealing device; But conventional seal washer can't guarantee reliable sealing performance; Simultaneously because fuse base root and transformer-cabinet hard contacts the damage that causes the fuse root easily, it is inner that transformer oil possibly get into fuse through injury region, greatly reduce the fail safe of transformer tank change.
Summary of the invention
The object of the invention provides a kind of sealing device that is used for oil-immersed fuse pedestal exactly in order to address the above problem, have double static sealing, positiver sealing performance and prevent that the base root from contacting the protective action of rapid wear firmly.
The objective of the invention is to realize like this: the invention provides a kind of sealing device that is used for oil-immersed fuse pedestal; Said fuse base is installed on the transformer-cabinet; Comprise pedestal base and base shell; The sealing device comprises the securing member be located on the fuse base pedestal and the sealing ring of being located at fuse base root place, and the cross sectional shape of said sealing ring is one circular and one and circular integrated lip.
At the above-mentioned sealing device that is used for oil-immersed fuse pedestal, the circular portion of sealing ring is located between the pedestal end face and transformer-cabinet of said fuse base.
At the above-mentioned sealing device that is used for oil-immersed fuse pedestal, the lip part of sealing ring is located between the outer surface and transformer-cabinet of fuse base shell.
At the above-mentioned sealing device that is used for oil-immersed fuse pedestal, fuse base root place is equipped with fluid sealant.
The present invention compares with the sealing device of general fuse, has following characteristics:
1. multi-sealed protective characteristic, effective more, reliable sealing performance;
2. have end face, radially double static sealing, reliable sealing performance more;
3. have reliable localization, effectively prevent sealing ring dislocation shear fails;
4. has the dual-seal effect that transformer oil and base root, end face static seal position are isolated;
5. have and prevent that the base root from contacting the protective action of rapid wear firmly;
6. the multi-sealed protection that has base rapid wear root.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the enlarged drawing of A among Fig. 1;
Fig. 3 is the schematic cross-section that the present invention adopts sealing ring.
Embodiment
Referring to Fig. 1 to Fig. 3; The present invention is used for the sealing device of oil-immersed fuse pedestal; This fuse base 2 is installed on the transformer-cabinet 12; This base comprises pedestal 23 and shell 22, and sealing device of the present invention comprises that securing member of being located on the fuse base pedestal 23 3 and the sealing ring 4 of being located at fuse base root 5 places, the cross sectional shape of said sealing ring 4 are one circular 41 and one and circular integrated lip 42.
At the above-mentioned sealing device that is used for oil-immersed fuse pedestal; The circular portion 41 of sealing ring is located between fuse base pedestal 23 end faces and the transformer-cabinet 12; Have base 2 and the effect of 12 end face static seals of transformer-cabinet; Fastening through being threaded of securing member 3, sealing property is reliable; The lip part 42 of sealing ring is located between the outer surface and transformer-cabinet 12 of fuse base shell 22; With base 2 elasticity lock rings static seal radially; Have transformer oil 11 and base root, the effect of end face static seal part seal, and have the effect that the base root contacts the rapid wear protection firmly.That sealing ring 4 adopts is high temperature resistant, oil resistant, ageing-resistant, elastomeric organic rubber composite material, and circular portion 41 is connected one with lip part 42, and the lock ring base has reliable localization, effectively prevents the sealing ring shear fails that misplaces.
At the above-mentioned sealing device that is used for oil-immersed fuse pedestal, it is between two kinds of materials handing-over damageable zone, sealing ring lip part 42 and base shell 22 peripheries that fluid sealant places base root 5.Sealing glue adopts has excellent oil resistant, insulation and humidity resistance; Remarkable high and low temperature resistance, the silicone rubber for sealing of weatherability; Multi-sealed protection with base root; When there are slightly damaged, micro-cracks in 5 two kinds of materials of base root handing-over position, have and prevent that transformer oil from getting into the inner dual-seal property of base, simultaneously also and the multi-sealed protection of bonding formation between sealing ring lip, base.
Above embodiment only supplies to explain the present invention's usefulness; But not limitation of the present invention; The technical staff in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited each claim.
Claims (2)
1. sealing device that is used for oil-immersed fuse pedestal; Said fuse base is installed on the transformer-cabinet; This fuse base comprises pedestal and shell, and the sealing device comprises the securing member and the sealing ring of being located at fuse base root place on the pedestal of being located at said fuse base, it is characterized in that; The cross sectional shape of said sealing ring is one circular and one and circular integrated lip
The circular portion of said sealing ring is located between the pedestal end face and transformer-cabinet of said fuse base,
Being shaped as of the lip part of said sealing ring is L shaped, is located between the outer surface and transformer-cabinet of fuse base shell.
