Abstract
The present invention discloses an artificial fog room for an insulator artificial pollution flashover test. Atomizing units are arranged at the four corners of an artificial climate room, and the fog out mouths of the atomizing units face a tested product at the center of the artificial climate room. The inputs of the atomizing units are connected to the output of a computer through data lines. The computer is arranged at the safe working area outside the artificial climate room and controls the fog out amounts of the atomizing units, a fog droplet diameter and the working condition of each atomizing unit through atomizing unit matched software. The atomizing unit and the computer are powered by a common 220V lighting circuit. According to the artificial fog room, the workload of test personnel can be reduced and manpower is saved, the wet controllable degree of an insulator surface pollution layer can be improved, and the accuracy of a test result can be improved.
