Abstract
The utility model provides a waterproof special sheath of GIS flange, relates to the power technology field, and its structure is that the dedicated waterproof sheath of different specification bolts and substrate are fire-retardant heat conduction type silicon rubber insulating material's flange joint face waterproof sheath. The utility model has the advantages that: the waterproof sheath has the characteristics of good insulating property, good hydrophobic and moisture-proof properties, excellent weather resistance and the like, is particularly suitable for outdoor use at high altitude and with strong ultraviolet rays, and has the service life of more than 20 years.
Description
Technical Field
The utility model relates to an electric power tech field especially relates to a waterproof special sheath of GIS flange.
Background
The position of a GIS connecting flange of a transformer substation, particularly the flange connecting surface connected through an insulating basin, can damage the original seal due to the influence of the operating environment. Accumulating moisture or moisture in little space, it is moisture that the sky is hot, and the sky is cold for the ice particle, has further aggravated the ageing and the destruction of sealed face, and this will lead to GIS equipment often, takes place the gas leakage in flange joint position, influences GIS equipment's safe operation. GIS equipment manufacturers have performed early sealing and waterproof treatment on flanges and bolts, but with the operation age of the equipment, the early waterproof is aged year by year; most bolts are not subjected to waterproof treatment, and the risk of replacing waterproof bolts in an electrified way is high; some products use insulating waterproof glue to flange joint face and bolt are unified, though played the guard action, but insulating waterproof material is attached to the equipment surface, overhauls and changes for the later stage of not being convenient for.
Disclosure of Invention
Not enough to prior art, the utility model provides a waterproof special sheath of GIS flange, its structure is: bolt seal waterproof sheath (1) is made by one-level sheath (7), go-between A (6), second grade sheath (5), go-between B (4), tertiary sheath (3) an organic whole, the diameter of one-level sheath (7) is greater than the diameter of second grade sheath (5), the diameter of second grade sheath (5) is greater than the diameter of tertiary sheath (3), go-between A (6) level links together one-level sheath (7) and second grade sheath (5), go-between B (4) become 45 degrees angles in the slant and link together second grade sheath (5) and tertiary sheath (3), bolt seal waterproof sheath (1) and flange joint face waterproof sheath (2) cooperation are used, bolt seal waterproof sheath (1) and flange joint face waterproof sheath (2)'s substrate is fire-retardant heat conduction type silicon rubber insulating material.
The flame-retardant heat-conducting silicone rubber insulating material is prepared by taking organic silicon rubber as a base material and adding substances such as flame retardance, electric arc resistance, reinforcement, heat conduction materials and the like for physical mixing.
The beneficial effects of the utility model reside in that: the waterproof sheath has the characteristics of good insulating property, good hydrophobic and moisture-proof properties, excellent weather resistance and the like, is particularly suitable for outdoor use at high altitude and with strong ultraviolet rays, and has the service life of more than 20 years; the protective sleeve forms a silicon rubber shell on the flange contact surface and the peripheral area of the GIS, and the corrosion of external water vapor to the flange is prevented. The silicon rubber has good weather resistance, so that the material can slightly deform along with the base material under the condition of alternating cold and hot environmental climate, and shows good servo performance. Even if a small gap is formed at the interface of the flange and the basin-type insulator, the sheath can still prevent external water vapor from entering the inside of the flange.
