【 摘 要 】

Compared with routine methods, the dry ice cleaning as an innovative, inexpensive and green cleaning technology, has excellent insulation and will not cause the pollution flashover accident. Due to the outstanding performance, the dry ice cleaning is very suitable for the insulator cleaning. In this study, the insulators were cleaned by dry ice with different cleaning parameters. The influence of different cleaning parameters on the dry ice cleaning was studied comprehensively. It is shown that reasonable air pressure, cleaning angle, dry ice mass flow, nozzle speed will improve the dry ice cleaning quality greatly, produce a high-efficiency performance. Furthermore, the dry ice cleaning can wash off the pollution of insulator surface effectively, give an obvious and ideal cleaning effect.
