Abstract
The present invention relates to a kind of new structural boring and the pillar porcelain insulator of uniform umbrella rib is had, hollow and inner surface has uniform umbrella prismatic protrusion in porcelain body, and ceramic insulator and flange are integral with cement glue mucilage binding.The advantages of this structure, is inside this porcelain insulator: first is that substituting solid porcelain ceramic insulator, mitigating insulator weight, creates for production, transport, installation and the construction of insulator and facilitate condition；Raw material are saved again while second is that mitigating weight, reduce the cost of insulator；Most importantly ceramic insulator inner surface is made into uniform umbrella prismatic bulge-structure, and while increasing insulator body product, the sudden strain of a muscle for considerably increasing interior insulator falls distance, improves the electric property of insulator.The present invention reduces the use of raw material on the basis of the properties for ensuring the insulator are stablized, improve the qualification rate of ceramic insulator processing quality and finished product, the cost for thus greatly reducing insulator adapts to the requirement of the super-pressure, superhigh intensity of the power transmission and transformation system of rapid development.
Description
Technical field
The present invention relates to a kind of new structural boring and with the pillar porcelain insulator of uniform umbrella rib, especially relate to
And the hollow and inner surface that a kind of substation is used to support effect has the pillar porcelain insulator of uniform umbrella prismatic protrusion.
Background technique
In recent years, with the steady growth of China's economy, power industry also high speed development therewith.Wherein, power grid construction and
Structural adjustment, actively expands west-to-east power transmission, reinforces north and south interconnection and on national network, increase north, in, the channel Nan San great ability of supplying electric power
Etc. being the project given prominence to the key points.So super-pressure long-distance sand transport is the trend of power system development so adapting to change development trend
It is required that the coarse type solid-core post porcelain insulator development of super-pressure, superhigh intensity become inevitable.For the reality for guaranteeing this target
Existing, for transmission system, reliability and economy are the main problem of system design, and substation is power transmission system
Hinge, power station is the important component of substation with solid-core post porcelain insulator, which is primarily subjected in operation
The insulation against ground effect of lasting mechanical stress and high voltage end, its continuous innovation and improve for power transmission system
Vital effect.
Summary of the invention
The purpose of the present invention is: be to provide that a kind of mechanically and electrically performance is more stable, and cost is lower, and convenient for production,
The new power plant pillar porcelain insulator of transport and installation.
Purpose to realize the present invention, is achieved using following technical scheme:
A kind of new structural boring and the pillar porcelain insulator with uniform umbrella rib, mainly have full skirt by middle part
Ceramic insulator and both ends flange composition, the flange sleeve be mounted in ceramic insulator end；The ceramic insulator is hollow
Shape.
With protrusion on the inner wall of ceramic insulator.
The protrusion is uniform umbrella prismatic.
It is integral by cement glue mucilage binding between flange and ceramic insulator end.
The exposed face of the cement glue on flange bottom edge is coated with one layer of silicone rubber coating.
Gasket is also lined between the end face and flange at ceramic insulator both ends.
The full skirt is that big umbellule is alternately arranged formula.
Compared with prior art, the beneficial effects of the present invention are:
1. new design outer dimension and it is solid be basically unchanged in the case where, the design of reasonable inside dimension is allowed to same
Under horizontal force 50kN effect, there is same mechanical performance, make a concrete analysis of as follows:
Insulator of the present invention: outer diameter D=255mm, d=125mm, critical section stress σ=60MPa；
Original insulator: outer diameter D=250mm is solid, critical section stress σ=60MPa.
2. insulator of the present invention is hollow and inner surface increases uniform umbrella prismatic protrusion, increasing inner surface intensity in this way
While increase the dry arcing distance of interior insulator, make interior insulator holding can not puncture,
3. insulator of the present invention by it is original it is solid become hollow, increase the product stability uprightly is installed while drop
The low weight of insulator, to reduce costs:
Insulator height 2000mm accounts for about the 15% of total weight than original weight saving 55kg.
4. insulator of the present invention solve coarse type solid insulator burnt present in sintering procedure it is impermeable or burning
The problems such as delay of problem and finished product is burst, shortens the production cycle, to reduce costs.
In short, the present invention is consistent with the purposes of original product, product structure is more reasonable, and performance is more stable, lighter,
It all creates for production, transport and installation and facilitates condition.Present invention saves raw material, improves manufacture craft, shortens life
The qualification rate for producing the period, improving finished product, thus greatly reduces cost, adapt to the superelevation of the power transmission and transformation system of rapid development
The requirement of pressure, superhigh intensity.
Detailed description of the invention
Fig. 1 is the new structural boring of the present invention and the pillar porcelain insulator cross-section structure with uniform umbrella rib is illustrated
Figure.
Fig. 2 is existing coarse type insulator the schematic diagram of the section structure.
Number explanation in figure: 1. flanges；2. gasket；3. cement glue；4. silicone rubber coating；5. ceramic insulator；6. convex
It rises.
Specific embodiment
Specific embodiments of the present invention are discussed in detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of new structural boring of the present invention and the pillar porcelain insulator with uniform umbrella rib,
Shape is identical as existing insulator, and mainly the ceramic insulator 5 by middle part with full skirt and the flange 1 at both ends form, and full skirt is
Big umbellule is alternately arranged formula.The flange 1 is sleeved on 5 end of ceramic insulator, between it is integral by 3 mucilage binding of cement glue,
The exposed face of the cement glue 3 on 1 bottom edge of flange is coated with one layer of silicone rubber coating 4, to guarantee between ceramic insulator 5 and flange 1
Leakproofness.It is also lined with gasket 2 between the end face and flange 1 at 5 both ends of ceramic insulator, to work as a buffer.Design of the invention
Main points are: ceramic insulator 5 is hollow shape, has uniform umbrella prismatic protrusion 6 on inner wall.This design is increasing table in insulator
While area, the sudden strain of a muscle for considerably increasing interior insulator falls distance, improves the electric property of insulator.
By Fig. 1 and Fig. 2 comparison it can be seen that the new structural boring and have uniform umbrella rib pillar porcelain
Insulator is more firm, lighter；It makes, transport and installs and is more convenient.
