摘要
Abstract
The brightness temperature of the insulator contamination was measured with microwave radiometer to gain the radiation energy characteristics of contamination. A detection model to calculate the equivalent salt deposit density (ESDD) and non-soluble deposit density (NSDD) was proposed through detecting the antenna temperature of insulators contamination with microwave radiometer, and a product model of ESDD and NSDD was proposed. Under dry (relative humidity 20％) and wet (surface water film) conditions, the relationship between the antenna temperature and ESDD as well as NSDD was studied, and the relationship between the antenna temperature and ambient temperature as well as air humidity respectively was studied in the case of different measurement angles. The impact of humidity on the model parameters was analyzed. The results show that both ESDD and NSDD are mutually independent as for the influence on the antenna temperature, and ESDD and NSDD can be simultaneously measured by measuring antenna temperature.关键词
