Description
Technical field
The present invention relates to glass-fibre technology fields more particularly to a kind of for producing insulator folded yarn glass fibre
Size and preparation method thereof.
Background technique
Glass fibre is a kind of inorganic non-metallic material haveing excellent performance, have light specific strength is high, chemical stability is good,
Good insulation preformance, it is heat-resisting do not burn, anticorrosive the features such as being unlikely to deform, be used as reinforcing material in composite material, electrical isolation
Material and heat-insulating material etc. are widely used in building, traffic, the energy, chemical industry, electronic apparatus, aerospace, environmental protection
Etc. national economy every field.With emerging manufacturing rise and the hair of material science, manufacturing technology and application technology
Exhibition, glass fibre kind is more and more, and quality also increases accordingly.
Insulator be electric system power generation, power transformation, transmission of electricity, distribution, with the indispensable insulator arrangement of electrical domain, it is main to rise
Mechanical connection and electric insulation effect.Insulator is divided into porcelain insulator, glass insulator, composite insulator by material difference and mixes
Close insulator.The cost of insulator accounts for the 11%~24% of transmission line of electricity total cost on early stage overhead transmission line, as network system
Key components and parts, the relationship between quality of insulator the safe operation of power grid.With insulator in transmission line construction at
This budget is glided year by year, and the cost of raw material caused by natural resources shortage but goes up year by year, this makes China's insulator manufacture neck
The technological innovation in domain and product change are had difficulty in taking a step.Under the present circumstances, manufacturing enterprise is to insulator new material, new technology, new
The research and development of technique still persistently carries out.
Currently, insulator manufacturing enterprise, China is no less than 200, production quantity, research level, the manufacturing technology of insulator
It occupies first place in the world with operating experience.It is long due to the extreme unevenness of the growing day by day of Electricity Demand and energy source distribution
Distance, large capacity, low-loss extra high voltage line, which emerge, to be developed, and the correlation that domestic each company develops extra high voltage line one after another is set
Standby, the extra-high voltage of a variety of materials type, large-tonnage insulator domesticize substantially.Due to UHV transmission line construction radiation and
It drives, the world the development Zou forefront of China's extra-high voltage insulator.Composite insulator be using glass fiber material as insulator, with
Epoxy resin combines, and is formed by connecting by various connection types and end metal attachment.Hybrid insulator is to be with epoxy resin
Insulator, mucilage binding metal-ware, or insulator fitting attachments is made with inorganic material and macromolecule organic material mixing.
State's inner insulator about uses the 42% of total amount mainly based on composite insulator, composite insulator have it is light-weight,
The advantages that anti-pollution dodges, moisture-resistant lightning pressure is high, process is simple, by large-scale use in the construction of China's power network line, this patent master
Invent glass fibre used in a kind of composite insulator.
Worldwide petrochemical energy shortages, clean energy resource become trend, and electric energy is used widely with its advantage easy to clean,
Therefore the all-round construction of electric power networks and wide covering will continue to carry out, simultaneously as the life of external insulator manufacturing enterprise, state
Produce atrophy, a piece of advantage of international market prospect.Sub-, non-, drawing developing country and less developed country there is no enterprise to have the ability at present
The insulator of high voltage, high quality is produced, these products rely on import substantially, and developed country is because of human resources and the means of production
It is at high cost to cause product price competition not dominant, therefore domestic insulator manufacturing enterprise welcomes opportunity in international market.Face
To insulator international market advantage, domestic production enterprise should build consensus, to improve product quality and after-sale service as objective, build
External market competition benign cycle is stood, establishes state's inner insulator in the top-ranking enterprise of international industry field, high quality services and one stream
Brand.
Insulator is to be fabricated using various types material by series of process, and the development for the sub-industry that insulate mainly takes
Certainly in the development of Material Field.The direction of insulator new material research has: mechanical performance is very excellent, stablize and light structure,
The permanent brilliance of electric property, mechanical electric performance are excellent.
In terms of composite insulator, external insulation full skirt sheath material continuously improves (epoxy resin → ethylene propylene diene rubber → room
Temperature vulcanizable silicone rubber → high-temperature silicon disulfide rubber), the research of the carefully and neatly done acid-resistant epoxy resin of monofuntional molecule structure improves
The acid-fast ability of interior insulation plug avoids dielectric strength caused by meeting acid because of fiber and declines, effectively prevents compound inslation
Sub- acid etching brittle failure.
With the development of international smart grid, the sub-industry that insulate must adhere to insulator new material, new technology, new process
Lasting research and development and innovation, such as first extrude thin layer sheath in mandrel outer and be placed on general injection in rubber mold again, can solve inside and outside
Insulator interface bonding and the multiple interface problem of external insulation；Using suspension type pillar hybrid insulator, have both porcelain insulator mechanical performance
Reliable and strong the resistance to pollution flashover ability of composite insulator silicon rubber material feature；A kind of novel shielding dress is installed additional at insulator both ends
It sets, then can effectively improve insulator lightning impulse withstand voltage, it is meant that the arcing distance of insulator is different in size have been determined
It is limited by the height of working voltage entirely.
