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, ultrahigh voltage power conveying circuit, and effect is that the not identical conductor of current potential is separated, and does not allow and has electric current to pass through between conductor, to keep current potentials different between them.Insulator is generally made by the high insulating material of resistance, with this material, can isolate conductor charged or different potentials, 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.Only have the earliest porcelain and glass insulator, the entirety machinery electric property of porcelain insulator is low, a little less than electrical insulation capability, electrocorrosion-resisting performance, ageing resistace, damping performance, creep-resistant property, the electrical strength of porcelain insulator, tensile strength, bending strength, the dirty poor performance of resistant, maintenance cost is high, and human input is larger.Glass insulator tensile strength, bending strength, damping performance, weather-resistant property is poor.To nineteen seventies, first high-temperature silicon disulfide rubber composite insulator comes out in Germany, compared with the conventional insulators such as porcelain, glass, has the advantages such as lightweight, intensity large, resistant dodges that ability is strong, maintenance and convenient transportation.Composite insulator consists of plug, full skirt and metal termination three parts.Composite insulator, claims again synthetic insulator, organic insulation, non-porcelain insulator, rubber insulator, polymer insulator.The product updating as traditional porcelain insulator, compound inslation in dirty wet, the high specific strength such as its excellent acid and alkali-resistance, water-fast, mist, ice and black excrement, lightweight, shock-resistant, operation maintenance convenient and the feature such as intrinsic breakdown prevention type structure, since the eighties, in various countries' electric power system, obtained a large amount of uses.Excellent operation department of resistant wet performance Shi Duo State Grid selects the major reason of composite insulator.Composite insulator is used to all kinds of medium and heavy pollution is regional, has effectively prevented the frequent pollution flashover accident occurring of original porcelain insulator, and has greatly reduced the operation maintenance workload of filthy regional power transmission and transforming equipment.Except natural atmospheric pollution level and meteorological condition, the external insulation performance of composite insulator depends on 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 and completely lose, and now the quality of beveled structure has determined the external insulation performance of composite insulator and affected the process of the Ageing of Insulators.Therefore beveled structure is composite insulator design and the key factor that must consider while selecting.Through retrieving relevant patent documentation, high voltage power transmission insulator has at present:
