Abstract
The utility model relates to a dust-lightning prevention insulator. The technical scheme is that compound rigid contaminant free coat is formed on the surface of the insulator. The contaminant free coat of the dust-lightning prevention insulator adopts the polytetrafluoroethylene first of all. The contaminant free performance of the coat is already proved by a plurality of domestic installations, such as non-stick cookers, no-clean vent fans, etc. The pollution-proof capability of the insulator is greatly increased. It is convenient to add filler into the material for dust prevention coat. The filler can improve the hardness and the adhesion of the coat. Consequently, the abrasive resistance and the service life of the coat are prior to the silicone rubber shed booster or the coat of the widely-known technology. Additionally, the hydrophobicity, the hydrophobicity forfeiture, the hydrophobicity resumption, the migration of hydrophobicity, the corrosion resistance, the index of power frequency flashover voltage test, the index of the pollution-proof flashover test, the index of the salt spray test, the index of the low temperature simulation test, and the index of the anti-icing test are all prior to the silicone rubber shed booster or the coat of the widely-known technology. The utility model has prominent advantages such as powerful dust-lightning prevention capability, low application cost, etc.
Description
Technical field
The utility model belongs to insulator, particularly relates to a kind of antifouling flash insulator.
Background technology
The pollution flashover accident of ultra-high-tension power transmission line causes owing to the insulator anti-soil dodges poor-performing greatly, and insulator surface incrustation is the basic reason that pollution flashover occurs.When insulator surface incrustation runs up to a certain degree, meet the bigger bad climate condition of humidity such as dense fog and then very easily cause big current drain, pollution flashover accident gently then takes place, heavy then cause net paralysed because of the explosion of insulator surface local overheating damages.
Dodge performance for improving the insulator anti-soil, the utility model of notification number CN2563718Y " the silicon rubber dirt-proof flashing increase is climbed skirt " discloses a kind of being adhesively fixed in the silicon rubber creeping-increasing skirt of umbellate form insulator surface, and it is the main structure of forming by the opening skirt type body of compression molding and the mouth of taking up and down of opening part.
In the known technology, using auto-vulcanization silicon rubber is that RTV coating also is anti-pollution flashover technical measures that adopt at present as the insulator dirt-proof coating.
Above-mentioned creeping-increasing skirt or coating all are the hydrophobicity performances that utilizes silicon rubber good, and the moisture performance that improves insulator is had positive effect.But silicon rubber creeping-increasing skirt or coating belong to elastic membrane, the lower and easy incrustation of surface smoothness, so silicon rubber creeping-increasing skirt or coating to the dirty characteristic of insulator to improve effect not remarkable.
Summary of the invention
The utility model is in order to solve in the known technology silicon rubber creeping-increasing skirt or coating for improving the inapparent technical problem of the dirty characteristic effect of insulator, and proposes a kind of antifouling flash insulator that can overcome its defective.
The utility model is taked following technical scheme for the above-mentioned technical problem that solves silicon rubber creeping-increasing skirt or coating and exist: what insulator surface was compounded with rigidity is not stained with the dirt coating.
The utility model can also be taked following technical measures:
The described dirt coating of not being stained with is to be made of transition bottom and ptfe surface layer.
The beneficial effects of the utility model and advantage are: this antifouling flash insulator surface the compound dirt coating of not being stained with at first select polytetrafluoroethylene for use, this coating be not stained with the dirt performance by some civil equipment such as non-stick cooker, exempt to clean range hood etc. and prove, therefore improved the dirty characteristic of insulator greatly.Be not stained with and be convenient in the material of dirt coating add the filler that improves its hardness and adhesive force, so this abrasion property and all be higher than silicon rubber creeping-increasing skirt or coating in the known technology useful life.Every index of moreover, be not stained with that hydrophobicity, hydrophobic forfeiture characteristic, the hydrophobic of dirt coating is restorative, migration of hydrophobicity, corrosion resistance and the test of power frequency flashover voltage, resistant being dodged test, salt mist test, simulated cold climate test and the test of anti-icing property all is better than silicon rubber creeping-increasing skirt or coating in the known technology.The utlity model has the anti-outstanding advantage that the pollution flashover ability is strong, use cost is low.
Description of drawings
Accompanying drawing 1 the utility model embodiment 1 structural representation.
Accompanying drawing 2 the utility model embodiment 2 structural representations.
Number in the figure: 1 insulator, 2 are not stained with the dirt coating.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment 1 as shown in Figure 1, and what insulator 1 surface recombination that is made of umbrella sheet and bowl head had a rigidity is not stained with dirt coating 2, and this coating is to be made of transition bottom and ptfe surface layer.The setting of transition bottom (not shown) be for ptfe surface layer and insulator 1 high strength compound.
The thickness of ptfe surface layer can be adjusted according to the high pressure amplitude of carrying, and in the salt mist test of the superficial layer 100h of 0.015mm thickness, it applies voltage can reach 15.6kv usually, and the duration is 1000h.
Embodiment 2 as shown in Figure 2, and insulator 1 is a porcelain bushing, and what its surface recombination had a rigidity is not stained with dirt coating 2, and the concrete structure of this coating is same as embodiment 1.
Claims (2)
1, antifouling flash insulator is made up of insulator body, it is characterized in that: what insulator surface was compounded with rigidity is not stained with the dirt coating.
2, antifouling flash insulator according to claim 1 is characterized in that: the described dirt coating of not being stained with is to be made of transition bottom and ptfe surface layer.
