Technical field
The present invention relates to a kind of high-voltage indoor support insulator, specially a kind of indoor post insulator of three element structures
Son.
Background technology
Support insulator is the insulation column of supporting high tension busbar and High-Voltage Electrical Appliances live part.According to contour structures and work
The difference for making condition is divided into outdoor, indoor two major classes.General indoor post insulator by hollow or solid cylindrical porcelain piece and
Metal-ware forms.According to the difference of metal-ware and mucilage binding mode, indoor post insulator is divided into outer mucilage binding, interior mucilage binding and interior
Outer three kinds of structures of joint mucilage binding.
The metal-ware mucilage binding of insulator with external fittings is outside porcelain piece, and the metal-ware mucilage binding of insulator with internal fittings is in porcelain piece
It is interior, the characteristics of inside and outside insulator with internal and exter nal fittings combines inside and outside mucilage binding insulator, mucilage binding in attachment thereon, the outer mucilage binding of lower attachment,
The present invention relates to insulator with internal fittings, insulating body is porcelain piece.
Porcelain belongs to inorganic material, and ceramic material has excellent electromechanical properties, and the performance of resistance to climate might as well.But its table
Face has hydrophily so that and the pollution layer of insulator surface makes moist, and insulator is caused to be likely to occur flashover under operating voltage,
Here it is the recurrent pollution flashovers of current electric system.
With the development of economy, filthy problem has become the serious problems generated with economic rapid growth.Operation
The main reason for empirical evidence, circuit powers off under the conditions of the pollution flashover of insulator (including indoor insulator) is up it
One.Other than serious industry is filthy, there be the natural filth in ocean or desert in the primary pollution source for influencing electric system at present.
Harm caused by the pollution flashover accident of insulator has seriously threatened the safety of electric system.Currently, how to improve power train
The antifouling work ability of system has become the big problem that domestic and international Utilities Electric Co. faces.
On the other hand, because the metal-ware mucilage binding of insulator with internal fittings is inside porcelain piece, the size of insulator compared with
Small, in the case of overvoltage, especially in lightning surge, discharge voltage is relatively low, influences its lightning protection properties.
Silicone Rubber Based Coatings are a kind of solutions of antifouling work at present, and the purpose of this coating is by porcelain (glass) insulator
The hydrophily on surface changes into hydrophobicity.But anti-pollution flashover coating is the product of site operation, exists and is not easy to ensure quality, material
And the problems such as manpower consumption is big, price is high, therefore a kind of provisional, remedial measure can only be used as.
And the lightning impulse voltage of the indoor post insulator after manufacture is improved, two traditional element structural insulation are not
It is possible.
The applicant exists《A kind of insulator that can improve external insulation electric strength》(China Patent No.
ZL200810197722.5 in), all insulating materials, all kinds, all voltage class and all alternating current-direct currents are being analyzed
After the structure of insulator, their common ground in structure are summed up, i.e., they are all by insulating body and connection gold utensil two
Above-mentioned all conventional insulators are referred to as two element structural insulations by big element composition, the applicant, connection gold utensil the
One element, insulating body is second element, and points out that this insulator is incomplete in structure.The patent according to
Creeping discharge during field distribution is theoretical, gas discharge is theoretical and gas is theoretical, and accessory system is added in conventional insulators,
Third element is formed, the imperfect structures of conventional insulators are changed into the complete structure of three elements.Three element structures are applicable in
In all insulating materials, all kinds, the insulator of all voltage class and AC and DC transmission of electricity insulator.
Since the scope of application of the patent is very extensive, in order to by the patent improvement and fining, be further
Three element structural insulation are enable to obtain the popularization of bigger in practical application, spy is directed to high-voltage indoor support insulator, proposes
A kind of indoor post insulator of three element structures.
Invention content
The purpose of the present invention is be directed to above-mentioned present situation, it is desirable to provide a kind of antifouling work ability that can improve this insulator
And lightning protection capability, the indoor pillar that three element structures that are more, more reasonably selecting are provided for substation's interior insulation configuration are exhausted
Edge.
The realization method of the object of the invention is a kind of indoor post insulator of three element structures, in the upper end of insulator
Accessory system in setting, the lower accessory system of lower end setting；
The upper accessory system is made of insulated part and current-carrying part two parts, and lower accessory system is by insulated part and leads
Electric part two parts composition, insulated part are in close contact with current-carrying part.
The present invention has the following advantages：
1, when support insulator top electrode generates corona discharge, the current-carrying part of the horizontal side surface of upper accessory system can
To attract the charge of corona discharge, the corona inception voltage and dry flashover voltage of insulator are effectively improved.
2, when electrode generates corona discharge under support insulator, the current-carrying part of the perpendicular lateral wall profile of lower accessory system can
To attract the charge of corona discharge, the corona inception voltage and dry flashover voltage of insulator are effectively improved.
3, when support insulator generates creeping discharge, upper accessory system and lower accessory system can guide the fortune of discharge charge
Dynamic rail mark extends discharge path, effectively improves the dry flashover voltage of insulator.
4, the insulated part of upper accessory system and lower accessory system has hydrophobicity so that the leakage electricity of insulator surface pollution layer
Stream is greatly reduced, and due to increasing creepage distance so that leakage current is further reduced, and effectively inhibits pollution flashover.
