Simulation and Experimental Study on Partial Discharge Decomposition Components of Air-insulated Switchgear Cabinet Considering the Influence of Temperature and Humidity
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 NO2,O3 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.
