Insulator post.
Background technology
Support insulator is supporting high tension bus and the insulation column of High-Voltage Electrical Appliances live part.It is by porcelain knob and upper and lower
Metal-ware is formed by cement mucilage binding.According to contour structures and the difference of working condition, it is divided into open air, outdoor two big classes.One
As the support insulator of outdoor installation use the filled circles porcelain knob of rod-like structure, i.e. band umbrella in a large number.To 154kV and higher voltage etc.
Level, conventional several support insulators are assembled into insulator post.Fig. 7 is that two High Voltage Outdoor support insulators are in series and are assembled into
Insulator post, the bottom electrode of upper insulator is fixed together by ring flange with the upper electrode of lower insulator, forms target.
Porcelain belongs to inorganic material, and ceramic material has excellent electromechanical properties, and the performance of resistance to climate is also very good.But
Its surface has hydrophilic so that the pollution layer of insulator surface makes moist, and causes insulator to be likely to occur under running voltage
Flashover, here it is the recurrent pollution flashover of power system at present.
Along with expanding economy, filthy problem has become as the serious problems produced with economic quickly growth.Run
Empirical evidence, the pollution flashover of insulator be up under the conditions of the one of the main reasons of circuit power-off.Except serious work
Outside industry filth, the primary pollution source affecting power system at present also has the filth naturally in ocean or desert.The pollution flashover thing of insulator
Therefore the harm caused serious threat is to the safety of power system.At present, the antifouling work ability of power system how is improved
Have become as the big problem that domestic and international Utilities Electric Co. faces.
Silicone Rubber Based Coatings is the solution of a kind of antifouling work at present, and the purpose of this coating is by porcelain insulator surface
Hydrophilic changes into hydrophobicity.But antifouling flush paint is the product of site operation, exists and be difficult to ensure quality, material and artificial
Consume the problems such as big, price is high, therefore can only be as a kind of measure provisional, remedial.

Son dispatch from the factory after lightning impulse voltage, the insulator of traditional structure is also extremely difficult.
The applicant is in " a kind of insulator that can improve external insulation electric strength " (China Patent No.
ZL200810197722.5), in, all insulant, all kinds, all electric pressures and all alternating current-direct currents are being analyzed
After the structure of insulator, summing up they common ground structurally, i.e. they are all by insulating body and to connect gold utensil two
The most elementary composition, above-mentioned all of conventional insulators is referred to as two element structure insulators by the applicant, and connecting gold utensil is the
One element, insulating body is second element, and points out that this insulator is structurally incomplete.This patent according to
Creeping discharge in Electric Field Distribution theory, gas discharge theory and gas is theoretical, sets up accessory system in conventional insulators,
Form the 3rd element, the imperfect structures of conventional insulators is changed into the complete structure of three elements.Three element structures are suitable for
In all insulant, all kinds, the insulator of all electric pressures and AC and DC transmission of electricity insulator.
Due to this patent the scope of application widely, therefore to further by this patent improvement with become more meticulous, for
Make three element structural insulations can obtain bigger popularization in reality application, special for High Voltage Outdoor support insulator post, carry
Go out the outdoor post insulator post of a kind of three element structures.
