Abstract
The invention relates to a hollow composite insulator which is used for a 2250 kV outdoor power frequency testing transformer in a power industry. The hollow composite insulator comprises end connecting pieces, an insulating pipe and an umbrella body, wherein the end connecting pieces are fixedly bonded on both ends of the insulating pipe, the umbrella body with an integral structure is fixedly bonded outside the insulating pipe, the insulating pipe is a winding pipe body which is provided with a coating and brushing layer, and the umbrella body is a whole body which is injected by using high-temperature silicon sulfide rubber as material. Because the coating and brushing layer of the insulating pipe adopts the structural form that epoxy resin glue and transformer resisting oil are brushed, mixed and solidified, thereby the transformer oil resistance of the hollow composite insulator is greatly increased; the umbrella body and the insulating pipe are combined by thermally fixing the umbrella body on the surface of the insulating pipe in a vacuum and high-temperature state, consequently, the bonding intensity of the umbrella body and the insulating pipe is high, and the performance is more stabilize and reliable.
Description
Technical field
Patent of the present invention relates to a kind of hollow combined insulator that a kind of power industry ultra high voltage testing equipment is used, a kind of specifically 2250kV outdoor industrial frequency experiment transformer hollow combined insulator.
Background technology
Relevant by retrieval patent documentation does not retrieve the 2250kV outdoor industrial frequency experiment transformer hollow combined insulator identical with patent structure of the present invention at present as yet.Existing power transmission and transformation and testing equipment mainly are divided into two big classes with insulator: the insulator of ceramic material and silicon rubber hollow combined insulator.The weight of insulator is big, easily injures other equipment after the blast, and anti-pollution characteristic is low, the burning process complexity, and large-scale insulator rate of finished products is low.For extra-high voltage electric transmission and transformation with insulator because it requires highly, at present domesticly can only depend on import.The applicant is the hollow combined insulator of application in the past, can apply to high-tension power transmission and transformation equipment preferably, then be necessary to carry out further developmental research for the 2250kV outdoor industrial frequency experiment transformer with hollow combined insulator, so that improve the quality and the level of power transmission and transformation and testing equipment.
Summary of the invention
The purpose of patent of the present invention is that a kind of employing alkali-free glass fibre will be provided is the materials for support insulated tube, and externally whole again pressure injection high-temperature silicon disulfide rubber is applied to the hollow combined insulator that the 2250kV outdoor industrial frequency experiment transformer supports.
For achieving the above object, patent of the present invention adopts following technical scheme:
A kind of 2250kV outdoor industrial frequency experiment transformer hollow combined insulator comprises end coupling, insulated tube, umbrella body, and end coupling cements in the two ends of insulated tube, it is characterized in that: the outside cementation at insulated tube has an integrally-built umbrella body; Described insulated tube is the winding body that transformer oil resistant is provided with the brushing overcoat.
The internal layer of described insulated tube is the aspect that epoxy resin and transformer oil resistant constitute.
Described insulated tube is to be impregnated with the hollow body that hot setting forms after the alkali-free glass fibre yarn coiling of epoxy resin.
Alkali-free glass fibre in the described insulated tube is uninterrupted alkali-free glass fibre yarn.
The material of described umbrella body is a high-temperature silicon disulfide rubber, and it includes with the lower part forms: methyl vinyl silicone rubber and white carbon, aluminium hydroxide, silicone oil, vulcanizing agent etc.
The composition by weight of described high-temperature silicon disulfide rubber is: methyl vinyl silicone rubber 20～50%, white carbon 20～60%, aluminium hydroxide 25～50%, silicone oil 2～5%, vulcanizing agent 1%.
Patent of the present invention compared with prior art has following remarkable advantage:
1, the brush layer that is coated with of insulated tube adopts epoxide-resin glue and transformer oil resistant to be coated with the mixing cured version of brush layer, can improve the oil preventing performance of product widely, makes the more reliable performance of product.
2, this hollow combined insulator umbrella body is as a whole, and combining between umbrella body and the insulated tube, is to make the high-temperature silicon disulfide rubber thermosetting in the insulated tube surface at the vacuum high-temperature state, thereby makes adhesive strength height, the performance of umbrella body and insulated tube more stable.Reliably, electric erosion resistance can obviously improve.
3, adopt uninterrupted alkali-free glass fibre coiled integral insulation pipe, guaranteed that the intensity of insulated tube is even.
