摘要
为改善SF_(6)断路器在严寒地区的使用性能,克服SF_(6)气体在温度低于-15℃时密度下降,温度低于-27.5℃时出现液化的问题,提出以聚酰亚胺(PI)薄膜作为加热源对气室进行加热的方案,利用ANSYS软件对其进行热流耦合分析。根据热模拟结果,结合相关性分析、选用自适应Kriging模型构建响应面,利用MOGA多目标遗传算法对PI面积和排布进行优化设计,通过仿真分析计算得到优化方案,与优化前的方案相比,优化后的PI薄膜的使用面积减少19%,功率消耗减少19%,SF_(6)气体的最大温差由39 K降到15 K,实现了对PI薄膜面积与排布的多目标优化设计。
In order to guarantee the performance of SF_(6)circuit breaker in cold environment,and to overcome the problem that the density of SF_(6)gas decreases when the temperature is lower than-15℃and the liquefaction occurs when the temperature is lower than-27.5℃,proposed a scheme to heat the SF_(6)chamber with graphene reinforced polyimide(PI)film as the heating source,and carried out the heat flow coupling analysis using ANSYS software.Based on the thermal simulation results,in order to optimize the area and arrangement of PI film,combined with correlation analysis,the adaptive Kriging model was selected to construct the response surface,and the MOGA multi-objective genetic algorithm was used to optimize the area and arrangement of the PI film.The area of the PI film after the optimization was reduced by 19%,and the power consumption was reduced by 19%.The maximum temperature difference of SF_(6)gas decreases from 39 K to 15K,The multi-objective optimization design of PI film in this paper can provide reference for the heating of SF_(6)circuit breakers.
