In order to apply dry ice to the insulator cleaning in power systems, it is necessary to obtain the optimal parameter range of each of the influencing factors. In this paper, a six-factor, five-level orthogonal test method is used to obtain a representative test plan. The influence level of air pressure, dry ice flow rate, cleaning distance, cleaning time, nozzle rotation speed and cleaning time on the cleaning effect were obtained. Results revealed that the optimal range for each cleaning parameter is: air pressure 0.7MPa∼0.8MPa, dry ice flow rate 2.5kg/min∼3.0kg/min, cleaning distance 10cm∼15cm, cleaning angle 10°∼20°, nozzle rotation speed 5∼15r/min, cleaning time 30s∼36s.
