Abstract

On March 12, 2017, in the Qingyishan area of Dandong City, a number of multi-point accidents with similar accidents occurred in a short period of time. Through the accident investigation, it was found that white powder adhered to the surface of the failed power equipment. After the accident, the white powder of the equipment was test and the test results showed that these white powders were the catalyst silver iodide particles of the shell. It was demonstrated that the rain-enhanced artillery shell did not explode at the designated altitude, and conductive silver iodide did not sufficiently fall down due to the action of the cumulonimbus cloud, and it was attached to the surface of the electrical equipment, causing the insulation resistance of the equipment to drop, resulting in phase-to-ground flashover discharge of the equipment. Through the investigation and analysis of the accident, this paper, on the basis of facts, expounds the failure of artificial precipitation, which the pollution flashover accident of the bare electrical equipment on the ground will be triggered and specific precautions will be put forward.
