Description
Technical field:
The invention belongs to the sub-manufacturing technology of High-Voltage Insulation field, relate to a kind of high voltage power transmission transparent insulator.
Background technology:
Insulator is the necessary supply on high pressure, the ultrahigh voltage power conveying circuit, and effect is that current potential conductor inequality is separated, and not allowing has electric current to pass through between the conductor, to keep current potentials different between them.Insulator is generally made by the high insulating material of resistance, can isolate conductor charged or different potentials with this material, and electric current can be circulated by certain direction.According to the difference of insulating material, insulator can be divided into porcelain insulator, glass insulator and compound inslation in three major types.Have only porcelain and glass insulator the earliest, the whole mechanical electric performance of porcelain insulator is low, a little less than electrical insulation capability, electrocorrosion-resisting performance, ageing resistace, damping performance, the creep-resistant property, the electrical strength of porcelain insulator, tensile strength, bending strength, the dirty poor performance of resistant, the maintenance cost height, human input is bigger.Glass insulator then tensile strength, bending strength, damping performance, weather-resistant property is poor.To nineteen seventies, the high-temperature silicon disulfide rubber composite insulator at first comes out in Germany, compares with conventional insulators such as porcelain, glass, has in light weight, advantages such as intensity big, resistant dodges that ability is strong, maintenance and convenient transportation.Composite insulator is made of plug, full skirt and metal termination three parts.Composite insulator claims synthetic insulator, organic insulation, non-porcelain insulator, rubber-covered, polymer insulator again.Product as the update of traditional porcelain insulator, compound inslation in dirty wet, high specific strength such as its excellent acid and alkali-resistance, water-fast, mist, ice and black excrement, in light weight, shock-resistant, operation maintenance convenient and intrinsic characteristics such as anti-breakdown type structure, obtained a large amount of uses in various countries' electric power system since the eighties.Excellent resistant wet performance is the major reason that electric power operation department of multinational family selects composite insulator for use.Composite insulator is used to all kinds of medium and heavy pollution is regional, has effectively prevented the frequent pollution flashover accident that takes place of original porcelain insulator, and has reduced the operation maintenance workload of filthy regional power transmission and transforming equipment greatly.Except natural atmospheric pollution level and meteorological condition, the external insulation performance of composite insulator depends on the monk's water-based and the external insulation structure design of material.The plug of composite insulator is the bearing part of insulator mechanical load, is again the major part of interior insulation simultaneously, is a kind of galss fiber reinforced resin rod, also claims fiberglass rod.Under the acting in conjunction of environment and electric stress, the hydrophobicity of material may temporarily weaken even completely lose, and the quality of beveled structure determined the external insulation performance of composite insulator and influenced the process of The Ageing of Insulators this moment.Therefore beveled structure is composite insulator design and the key factor that must consider when selecting for use.Relevant by retrieval patent documentation, the high voltage power transmission insulator has at present:
