The invention relates to a 66kV manual icing snow climate test apparatus, and especially relates to a 66kV manual icing snow climate test apparatus. The apparatus comprises a casing and an ice marking device, and is characterized in that the casing is respectively connected with a snow spraying system, a wind tunnel system, an overpressure resistant test system and an electric leakage test system. The casing is internally provided with a humiture wind speed monitoring system, the top portion inside the casing is connected with a suspension iron wire, the suspension iron wire is connected with a tested product insulator string, the tested product insulator string is respectively connected with the overpressure resistant test system and the electric leakage test system, and the lower port of the tested product insulator string is connected with a ground wire. The apparatus provided by the invention meets the requirement of a 66kV insulator for a manual icing pollution test and also has the remarkable advantages of simple structure and clear and convenient man-machine interface data processing, thereby being suitable for popularization and application in the industry of electric power.
