| As a carrier of electrical equipment,the electrical module is being applied at an increasing speed and scale with the advent of the era of industrial intelligence.Especially in some areas with harsh environments,the existence of electrical modules is electrical equipment.Necessary conditions for stable operation and normal work.Considering the unique geographic location and natural resources of the Arctic region,it has played a pivotal role in the study of global change.The eight Arctic countries have successively introduced their respective Arctic strategies,all of which regard the Arctic region as an important part of the country’s long-term strategy.However,the extremely harsh climatic conditions in the Arctic region make the temperature requirements of electrical equipment prominent,and even under normal conditions,it cannot even be used normally.Therefore,the research on the insulation characteristics of the electrical equipment carrier in the Arctic region has become the core subject of many scholars scrambling to study.Based on this background,this paper proposes the research on the insulation characteristics of the electrical inter-modules in the Arctic region.Based on this,this paper first conducts a series of researches on the current status of insulation at home and abroad,and then discusses the relevant theories of thermodynamics.The influence of related factors on the insulation design of electrical room modules was discussed at two levels of extreme environmental climate in the Arctic area and the outer enclosure structure of electrical room modules.Based on this,the overall strategy for the insulation and energy saving of electrical room modules in Arctic areas was briefly presented;Secondly,the finite element analysis was carried out on the outer insulation board of the electrical room module,and the design principles and evaluation requirements for the insulation of the electrical room module were put forward.Based on this,the heat of the insulation boards of different surface layers and different insulation materials was obtained using Ansys software.Flow density curve chart,comparing and analyzing the cold bridge phenomenon through the model with cold bridge nodes,and using intuitive temperature field cloud diagram analysis to provide a certain theoretical basis for the cold bridge protection of the electrical module;Thirdly,the heat transfer analysis and research on the exterior window structure that has a significant impact on the insulation of the electrical module is carried out.Based on the types and advantages and disadvantages of the exterior window,the energy-saving measures for exterior window insulation are proposed;then single glass and double glass are selected.Two types of glass structure,related research and analysis on the heat transfer characteristics of glass;Finally,the overall simplified physical model of the Arctic electrical module was established.Using Fluent software,given the initial conditions and boundary conditions in the Arctic,the thermodynamic simulation and temperature field analysis of the electrical module were performed to obtain an intuitive electrical room.Cloud diagrams of the airflow field and temperature field of the module;Based on this,the potential thermal insulation factors inside the electrical room module are researched.Through the method of controlling variables,the speed of the air outlets of the electrical room modules and the different air outlets are respectively controlled by Fluent software.The position of the return air outlet was analyzed for temperature field and air flow field,and the more reasonable wind speed requirements of the HVAC air outlet and the location of the air inlet and return air outlet were obtained under the conditions of the Arctic area of the electrical module. |
