摘　　要：为探究温度和湿度对空气局部放电时特征组分生成特性的影响,文中仿真计算了不同温度和湿度条件下空气分解反应中可能出现的组分以及生成规律,并搭建了温湿度可控的空气局部放电分解实验平台研究了3种不同典型缺陷下空气局放分解特性随温湿度的变化规律。仿真和实验结果表明,空气局部放电生成的主要组分有NO_(2)、O_(3)和CO,3种组分的含量随温湿度条件的变化均存在明显的差异,不同类型缺陷下的局部放电分解组分受温湿度的影响不同。研究结果可为基于分解组分分析的局部放电缺陷检测提供参考。For exploring the influence of temperature and humidity on the generation characteristics of characteristic components in case of partial discharge in the air,the possible components and generation in the air decomposition reaction under different temperature and humidity conditions are simulated and calculated in this paper,and a tem⁃perature and humidity controllable air partial discharge decomposition experimental platform is set up.The variation of partial discharge decomposition characteristics of air with temperature and humidity under three different typical defects is studied.The simulation and experimental results show that the main components generated by partial dis⁃charge in the air are NO_(2),O_(3)and CO.The contents of the three components are obviously different with variation of temperature and humidity conditions.The influence of temperature and humidity on partial discharge decomposition components under different types of defects is different.The study results can provide reference for partial discharge defect detection based on decomposition component analysis.
