Description

A kind of resistant porcelain insulator

Technical field

The present invention relates to insulator technology field, specially a kind of resistant porcelain insulator.

Background technique

The distance of China's power Transmission is more and more remoter at present, often to use insulator in power Transmission, substation and defeated Electric line conveys electric energy in such a way that high voltage transmits electric current, the high potential difference (electricity between electrical body and supporting frame or the earth Pressure) it is undertaken by insulator.Insulator is mounted in the device between the conductor of different potentials or between conductor and ground potential component Part is resistant to voltage and mechanical stress effect.It is a kind of special insulation control, can be played in overhead transmission lines Important function.Insulator is about several hundred a nucleotide pairs, is to be usually located at promoter with positive controlling element (enhancer) or negative tune Control a kind of regulating and controlling sequence between the factor (for heterochromatin).Insulator itself both without positive-effect, does not have the expression of gene yet There is negative effect, effect does not allow only other controlling elements to have an effect the activating effect or inactivating effect of gene, between one's early years Insulator is chiefly used in electric pole, and the one end for being slowly developed in high type high-tension bus-bar connection tower has hung the insulator of many plate-likes, it It is usually to be made of glass or ceramics to increase creepage distance, is just insulator.Insulator should not be due to environment and electricity Loading condiction various electromechanical stress caused by changing and fail, otherwise insulator would not generate great effect, will Damage the use and service life of whole route.

Insulation between the electrical body and framework and facility of open power transmission and transformation system, including ontology interior insulation, the air gap The surface insulation of insulation and insulator, and most weak is surface insulation.Classical and reliable insulating materials is ceramic insulator Or glass insulator.

Insulator using very extensive, insulator has highly important effect, insulator in electric power transportational process Composite insulator is formed after monomer insulator is attached in use can promote the utilization of insulator monomer well Rate, but nowadays quickly and easily insulator monomer can not be connected well in use, it is not easy to work people Member is installed and is replaced, and is increased staff's burden, is wasted the time, can not preferably guarantee the use of insulator, drops The low service life of insulator, and existing insulator can not play the role of in use it is antifouling well, and can not Dust on insulator is removed, insulator is easy dust accretions in use and is excessively seriously affecting insulator just It is often used, be easy to cause the damage of insulator, cause unnecessary economic loss.
