The Influence of Complex Environmental Conditions on the Corrosion Degree of Outdoor Typical Transformer Equipments

The equipment of outdoor substations are operated in complex atmosphere and electromagnetic environments for a long time. They are often affected by these complex environments and special corrosion occurs, which is not conducive to long-term stable operation of the substation and may affect the quality of power. Therefore, it is necessary to explore the influence of various typical factors on the corrosion degree of substation equipment in complex environment. In this paper, the corrosion simulation of substation equipment is carried out by COMSOL software, and the influence of electromagnetic factors such as SO 2 , salt load and leakage current on the corrosion degree is explored. The study found that salt load, SO 2 and pH can significantly accelerate the corrosion of the equipment, and the degree of influence is large.
