Connection line main carriers, are the important fulcrums for supporting power grid, and importance is self-evident.Domestic and foreign experience shows route thing
Therefore the problem of being all much insulator quality problems, environmental problem, the operation time limit, it is the basic original for leading to line flashover phenomenon
Cause.
The producer for producing insulator at home is numerous, and each producer's control of product quality system is different, the insulation produced
Protonatomic mass is irregular, avoids so needing to test to production insulator because interruption of service occur in quality problems.Having
A little area day and night temperatures are big, and daytime, the sun was exposed to the sun that insulator surface temperature is very high, and evening temperature decrease insulate under such circumstances
It is easy to appear self-destruction especially toughened glass insulators for son, to prevent the occurrence of such from needing this environment of manual simulation
It tests to insulation.
So far, string is fallen to insulator arc-over both at home and abroad and has carried out a large amount of research work, a large amount of New insulated
Son is widely applied on the transmission line, especially glass insulator.With the passage of the operation time limit, toughened glass insulator exists
Extreme environment has certain self-destruction probability, however insulator self-destruction seriously affects route operational safety.Insulator self-destruction with it is extreme
Adverse circumstances are closely bound up, and insulator self-destruction causes creepage distance to reduce disappearance, thus be the very big reason for leading to line flashover,
It is also possible to occurring falling string accident caused by self-destruction.
Transmission line of electricity lending analysis and mechanical performance have a significant impact to the safe operation of route, exhausted outside transmission line of electricity
One important evidence of edge configuration is exactly dielectric level of the external insulation under severe weather conditions, wet in the season air of rainy water
Spend it is larger, have insulator self-destruction in the case of, rainwater falls in insulator surface and is readily formed moisture film, and insulator creep distance can reduce,
So it is the main reason for causing flashover fault to occur that self-destruction insulator creepage distance, which reduces and disappears,.
Therefore, examining to glass insulator thermal shock has extremely important effect to transmission line safety operation.For a long time with
Come, operation department and experimental study personnel analyze and study to flashover fault all the time, and purpose includes three sides
Face: first is that electric property, second is that mechanical performance, third is that environmental factor.Electric property is determined by self structure, and mechanical performance ring
Border factor can manual simulation's inspection.
Summary of the invention
