Abstract
This utility model provides a kind of antifouling flash insulator, including insulator body, it is characterised in that insulator body surface and the back side all set gradually insulating coating, tie coat and antifouling flash coating layer from center to edge.The insulating properties between insulator body surface and steel cap and the body back side and steel foot are improved by the insulating coating in insulator body surface and centre, the back side, reduce electric current to pass through, thus improve the flashover voltage that insulator is overall, improve resistance to pollution flashover performance, insulator body surface and the anti-wear performance at the back side, weather resistance, water resistance, hydrophobicity performance and organic pollution catalytic degradation performance is improved again by tie coat and antifouling flash coating layer, effectively reduce filth to pile up, reduce pollution flashover odds, it is ensured that electric power netting safe running.
Description
Technical field
This utility model relates to a kind of antifouling flash insulator, belongs to electrical equipment technical field.
Background technology
Insulator, in the power distribution equipment of power plant and transformer station, is used for supporting and fix current－carrying conductor, and makes current-carrying lead
Between phase and phase and insulating between phase and ground of body.It is therefore desirable to insulator should have enough dielectric strengths and mechanical strength,
And can safe operation under the environment such as rugged environment such as high temperature, humidity, many dust, dirt.Generally, the insulator of on-line operation
Mostly being in atmospheric environment, surface can gradually deposit one layer of dunghill, the solubility when running into wet weather, in dunghill
Material can be dissolved in water and form conduction moisture film, thus has leakage current and flows through along insulator surface, the size of current flow through
Depend primarily on degree of fouling and damp degree.When dirty and when making moist more serious, local arc can progressively develop, when reaching or
When exceeding critical state, electric arc can run through the two poles of the earth, forms pollution flashover, is called for short pollution flashover.Once insulator produces pollution flashover, can be to electricity
The safe operation of Force system brings serious threat.At present, the preventive measure for insulator contamination mainly has: strengthens insulator and climbs
Electrical distance, enforced insulator surface hydrophobic performance, human at periodic intervals's cleaning etc., the subject matter that these measures exist has: 1. can not
The problem fundamentally solving dunghill deposition；The most relatively costly.Prior art uses coating silicon rubber to insulator surface
Way, but silicone rubber is elastic material, easily adsorbs dust, and when the insulating properties of insulator reduce, people are usual
Can not find in time, the most easily cause major accident.
Summary of the invention
For overcoming deficiencies of the prior art, this utility model provide one have superior isolation, wearability,
Resistance to water, the antifouling flash insulator of weather resistance.
This utility model realizes above-mentioned purpose and be the technical scheme is that a kind of antifouling flash insulator, including insulator
Body, it is characterised in that insulator body surface and the back side all set gradually to edge from center insulating coating, tie coat and
Antifouling flash coating layer.
Described insulator body surface and the back side:
Insulation coating layer thickness be 2～4 μm, width be 15～20mm；
Tie coat thickness be 2～4 μm, width be 10～15mm；
Antifouling flash coating layer thickness be 2～4 μm, width be remaining insulator body edge.
Between described insulating coating and tie coat, between transition zone and antifouling flash coating layer, it is seamless connection.
The insulating coating RTV dope layer at described insulator body surface and the back side.
The transition zone at described insulator body surface and the back side is: VRTV coating:VSilane coupler:VTiO2 colloidal solThe mixing of=2:1:7 is coated with
Layer.
The antifouling flash coating layer at described insulator body surface and the back side is TiO2+SiO2Mixed coating.
The beneficial effects of the utility model are: use such scheme, can pass through insulator body surface and back side central part
The insulating coating of position improves the insulating properties between insulator body surface and steel cap and the body back side and steel foot, reduces electric current
Pass through, thus improve the flashover voltage that insulator is overall, improve resistance to pollution flashover performance, then carried by tie coat and antifouling flash coating layer
High insulator body surface and the anti-wear performance at the back side, weather resistance, water resistance, hydrophobicity performance and organic pollution catalysis fall
Solve performance, effectively reduce filth and pile up, reduce pollution flashover odds, it is ensured that electric power netting safe running.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.The basic material used is commercially available prod, institute
The operation used is the routine operation of this area.
As it is shown in figure 1, the antifouling flash insulator that this utility model provides, including insulator body 1, insulator body 1
Surface and the back side all set gradually insulating coating 4, tie coat 3 and antifouling flash coating layer 2 from center to edge；
Described insulator body 1 surface and the back side:
Insulating coating 4 thickness be 2～4 μm, width be 15～20mm；
Tie coat 3 thickness be 2～4 μm, width be 10～15mm；
Antifouling flash coating layer 2 thickness be 2～4 μm, width be remaining insulator body edge.
Between described insulating coating 4 and tie coat 3, between transition zone 3 and antifouling flash coating layer 2, it is seamless connection.
The insulating coating 4RTV dope layer at described insulator body 1 surface and the back side.
The transition zone 3 at described insulator body 1 surface and the back side is: VRTV coating:VSilane coupler:VTiO2 colloidal solThe mixing of=2:1:7
Coating.
The antifouling flash coating layer 2 at described insulator body 1 surface and the back side is TiO2+SiO2Mixed coating.
