Abstract
The invention relates to an insulation accessory for high-voltage transmission lines and power stations of electrical power systems, i.e. a high-voltage high-strength porcelain insulator. The high-voltage high-strength porcelain insulator comprises the following raw materials in parts by weight: 24 parts of feldspar, 25 parts of bauxite, 20 parts of burned aluminite, 36 parts of Cab-O-sil, 27 parts of northeast China ash clay, 27 parts of white drystone, 72 parts of clay in Faku town and 45 parts of clay in Tian Shi Fu town. A technology for manufacturing the high-voltage high-strength porcelain insulator comprises the following steps of: raw material cleaning, ball milling, wet grinding, sorting and crushing, preparation according to a formula, iron removal, squeezing, vacuum extruding, forming, sintering, sand feeding, glazing, drying, grinding and cementing, testing and packaging. By reasonably selecting different types of clays and materials, the high-voltage high-strength porcelain insulator has good processing property and sintering performance, the product percent of pass is increased, and the mechanical property and the electric property indexes of the porcelain insulator meet the using requirements.
Description
?
Technical field
The present invention relates to the insulation accessory of a kind of power system high tension power line, power station use, i.e. the high pressure high-strength porcelain.Also be fit to do power plant's enclosed busbar insulator.
Background technology
In the prior art, electroceramics mainly refers to also claim porcelain insulator for the insulating ceramic of ultra-high-tension power transmission line and power station and various electrical appliances, in overhead transmission line, play an important role, and be the important component part of power industry.Porcelain insulator plays two basic roles in overhead transmission line, i.e. support wire and prevent that electric current from returning ground.Porcelain insulator is comprised of insulating ceramic and metal-ware, and that the insulating ceramic surface has is a plurality of, interval, outstanding circular full skirt.The insulating ceramic material choice is different, its mechanical property, electric property difference, and the reasonable selection raw material is the important leverage that guarantees product performance, uses safety.This series products is of a great variety, and it is different to fill a prescription, the assurance that is only quality product up to standard.
Summary of the invention
The objective of the invention is provides a kind of mechanical property, electric property conformance with standard for above-mentioned deficiency, satisfies the high pressure high-strength porcelain of service requirements.
Technical solution of the present invention is: the high pressure high-strength porcelain is comprised of following parts by weight raw material: 24 parts of feldspars, and 25 parts of bauxitic clays burn 20 parts of aluminite, 36 parts of ground silicas, 27 parts of Cortex Fraxini mandshuricae clays, 27 parts in white spirit stone, 72 parts of Faku County's clays, 45 parts of field master worker's clays.
Common process is made: raw material cleaning → ball milling → wet grinds → selects materials pulverizing → extrude → moulding → burn till → go up sand → glazing → drying → grinding mucilage binding → experiment → packing by formulated → deironing → squeezing → vacuum.
Advantage of the present invention is: by choose reasonable dissimilar clay and material, make material have good processing performance, firing property, physical strength is high, has improved product percent of pass.Mechanical property, electricity function index satisfy service requirements.
Below in conjunction with embodiment embodiments of the present invention are described in further detail.
