110 kV模块化变电站电气设备发热建模特性分析及布点现场测试方案OA

110 kV modular substation adopts a modular construction approach,featuring standardization,factory pre-fabrication and intensive design,making it the preferred construction model for smart substations.110 kV modular substation in operation is affected by the difference of climate environment in different regions,and the problem of heat accumulation and condensation of electrical equipment is existed,which affect seriously both life,safe and sta-ble operation of the electrical equipment.In this paper,the heat generation characteristics of 110-A2-6 modular sub-stations and their electrical equipment in Jiangsu province are taken as the research subject.The heat generation characteristics of such main electrical equipment as transformers,capacitors,switchgear,GIS are modelled and ana-lyzed,and the heat generation patterns of the electrical equipment in modular substations are obtained.Finally,the method of placing loop control sensors is introduced in the 110 kV modular substation,and the measured data is matched with the heat generation model,thus providing a reference basis for the improvement of the heat and humidi-ty environment in the modular substation.
