Description

technical field [0001] The invention relates to a composite insulator of a power transmission line and a detection method for a distribution diagram of a polluted area, in particular to a method for revising a distribution diagram of a polluted area of ​​a composite insulator based on an equivalent salt density value. Background technique [0002] The composite insulator mainly includes three parts: glass fiber epoxy resin lead rod (hereinafter referred to as mandrel), silicone rubber shed and fittings. The fittings are metal conductors located at the upper and lower ends of the composite insulator. The axial voltage distribution of the small long rod insulation structure is extremely uneven, especially at the wire end where the field strength is the highest. With the increase of the line voltage level, the structural size of the composite insulator will increase accordingly, and its axial voltage distribution will become more and more uneven, which will easily cause corona ...

AI Technical Summary

Problems solved by technology

This is due to the fact that composite insulators have many advantages, but there are also some problems: First, the silicone rubber shed sheath currently used is relatively soft in texture. Because the insulator has been in the field for a long time, it is affected by bad weather and the environment. The silicone rubber shed sheath on the outer surface is very easy to damage and damage the sealing performance, resulting in a decrease in insulation performance; second, the long rod-shaped structure of the composite insulator makes the yield low, making packaging, transportation, installation and operation and maintenance difficult, and Potential distribution is not uniform, if there is damage, the whole root must be replaced, which will increase the maintenance cost

At present, with the continuous increase of air pollution in various places, the speed of change of atmospheric environmental quality is accelerating, making the regular revision of the grid pollution area distribution map more and more lagging behind the change of atmospheric environmental quality
