The invention discloses a device for detecting a surface
dirt morphology of an insulating material in a
haze environment. The device comprises a high-speed
airflow simulation generation device used for simulating the
haze environment under a high-speed
airflow, an alternating-current and direct-current pressurization and flashover experiment device used for applying a
voltage to an insulation sample, an
electric field intensity detection device used for detecting
electric field distribution on a surface of the insulating sample in a
voltage applying process, and a microscopic amplification device used for observing a
microstructure of dirty particles on the surface of the insulating sample. The high-speed
airflow simulation generation device is provided with an observation window, and a
discharge observation device used for observing a flashover path after the surface of the insulation sample is polluted is arranged outside the observation window. The invention further discloses a method for detecting the surface
dirt morphology of the insulating material in the
haze environment. The device for detecting the surface
dirt morphology of the insulating material in the haze environmentstudies the
microstructure of the surface dirt of the insulating material in the high-speed airflow haze environment and surface flashover phenomenon development, and is of great significance to prevention of insulator
pollution flashover accidents.
