Abstract
The utility model relates to a highly bending resistant composite post insulator for high-voltage transmission in the electricity industry, comprising a post body. The highly bending resistant composite post insulator is characterized in that the post body is in a sectional structure and consists of an upper post body and a lower post body which are equal in size, wherein the upper post body and the lower post body are connected through a flange; the outer ends of the upper post body and the lower post body are respectively provided with electric fittings, and both the upper post body and thelower post body respectively consist of a mandrel bar and a composite insulating chute boot coated outside the mandrel bar. The utility model overcomes the defects of poor bending and corrosion resisting capability of the prior porcelain post insulator and has the advantages of simple structure, good bending and corrosion resisting performance and good insulating performance.
Description
Technical field
The utility model is specifically related to the high bending resistance post composite insulator that a kind of power industry high voltage power transmission is used.
Background technology
The high-voltage strut insulator of common outdoor use is generally porcelain strut insulator, and the use of porcelain strut insulator is used extensively near a century.But there is the defective that self can't overcome in traditional porcelain insulating pillar always: the destructible because ceramic material is very crisp, this means that it damages easily when loading and unloading, transportation and outside destroy, particularly when the length of porcelain strut insulator is longer, the non-constant of bending resistance, the very easy fracture; Cause the dismounting difficulty owing to the dense meeting of ceramic material simultaneously, and need very big structural support thing; The stable chemical bond of ceramic material means that also it has very high surface energy, easily by water infiltration, thereby easily causes the complete flashover of insulating surface under filthy condition, and resistance to corrosion is poor, and this is damaged the reliability of porcelain strut insulator; Moreover the manufacture process of porcelain strut insulator comprises a lot of steps, produces and the time of delivery is long, efficient is low.
Along with increasing external high-voltage electrical apparatus product after China's development of electric power industry and the accession to WTO enters the domestic market, make domestic high-voltage electrical apparatus manufacturing enterprise be faced with great challenge.So release the new construction product that structure is more reliable, operation and maintenance is easier, combination property is better very important meaning is arranged.
The utility model content
The purpose of this utility model is the defective that solves the bending resistance of prior art porcelain strut insulator, resistance to corrosion difference, provides a kind of composite material that adopts to divide body structure, has bending resistance, corrosion resistance is good, the high bending resistance post composite insulator of good insulation preformance.
The utility model is achieved through the following technical solutions:
It is a kind of high bending resistance post composite insulator, comprise cylinder, it is characterized in that described cylinder is a segmentation structure, last cylinder and lower prop by the five equilibrium cylinder are formed, connect by flange between last cylinder and the lower prop, the outer end of last cylinder and lower prop is separately installed with gold utensil, and described upward cylinder and lower prop are formed by plug and the compound inslation umbrella cover that is coated on mandrel outer.
Flange is made up of upper flange plate and lower flange, and upper flange plate is installed in cylinder that end relative with lower prop respectively with lower flange, and described flange is made by cast steel hot galvanizing material.
Described plug is solid glass fiber reinforced epoxy resin leading-drawing rod.
Described umbrella cover is made by high-temperature silicon disulfide rubber, and umbrella cover comprises sheath and full skirt, and full skirt is downward-sloping
During the utility model assembling, flange, gold utensil adopt whole compression joint technique to connect with the end of last cylinder, lower prop, the middle part of last cylinder, lower prop utilizes bolt by upper flange and lower flange, umbrella cover adopts the technology of squeezing bag penetrating umbrella to be coated on the plug, and integral body has higher bending resistance and torsional property.
The utlity model has simple in structurely, bending resistance, corrosion resistance are good, the advantage of good insulation preformance.Cylinder of the present utility model has adopted the branch body structure of two-section up and down, has not only improved bending resistance, has also improved its rigidity greatly, has reduced side-play amount.Insulated part of the present utility model adopts to be made up of high strength glass fiber leading-drawing rod and silicon rubber umbrella cover, it has in light weight, simple in structure, mechanical strength advantages of higher, the more important thing is that silicon rubber compound inslation surface has hydrophobicity and migration of hydrophobicity, can improve the stain resistance of product greatly, non-maintaining, do not need periodic inspection, be coated with silicone oil, save a large amount of regular maintenance expenses.Plug of the present utility model and umbrella cover are born machinery and electrical load respectively; mechanical strength and electric property are separated; combine mandrel material stretching bending resistance good mechanical property and the umbrella cover material pollution performance of anti-atmosphere the, advantage that ageing resistace is superior, brought into play their best-of-breed functionality jointly.
