【Abstract】 Taking the smog pollution as an example, the temperature field model is used to analyze the influence of environmental pollution on the degree of linear loss of the electricity information collection system. According to the structural symmetry of the electricity information collection device, a two-dimensional model is used to describe the temperature field of the device. The model includes three equations of energy conservation, momentum conservation and mass conservation. At the same time, the relationship between density, thermal conductivity, dynamic viscosity and device temperature of the device outside the smog pollution environment is calculated. Based on the model, the device for smog pollution is calculated. The effects of ion mobility, charge density and corona discharge intensity on the surrounding flow field were analyzed in three stages. The effects of smog-contaminated particulate matter movement on the surface insulation and corrosion of the device were analyzed in three stages.更多还原
