摘要
Abstract
The flashover test of salt fog simulate the flashover of polluted insulators in salt fog environment. There are a lot of high conductivity fog droplets near the insulator, the environment is different from the steam fog environment. Under the salt fog environment, the influence of different pressurization methods on flash-over test results is different from that of steam fog. Therefore, this paper adopts rise-voltage method and up-and-down method on flashover of insulators contamination in salt fog environment simulation, obtained flashover voltage under different salt density, and compare the curve fitting results. The experimental results show that the results obtained by the risevoltage method are higher than that of the up-and-down method in the experiment of AC salt fog flash-over test. The flash-over voltage gap between the two methods is in the range of 14％ to 36％. The results can be used as reference in artificial salt spray test in different research units.关键词
