摘要

研究以雾霾污染为例利用温度场模型分析了环境污染对用电信息采集系统同期线损程度的影响,根据用电信息采集装置线路的结构对称性,采用二维模型描述装置温度场,该模型包括能量守恒、动量守恒和质量守恒三个方程;同时计算雾霾污染环境下装置外绝缘气体密度、导热系数、动力粘度和装置温度之间的关系;基于该模型计算了雾霾污染对装置周围流场离子迁移率、电荷密度、电晕放电强度的影响,在此基础上分三个阶段分析了无风情况下雾霾污染颗粒物运动对装置外绝缘表面积污和腐蚀的影响,实现了环境污染对用电信息采集系统同期线损程度的影响分析。
        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.
