基于多物理场的大电流固体绝缘开关柜温升特性研究
Research on Temperature Rise Characteristics of High Current Solid Insulated Switchgear Based on Multi-physical Field
摘要
Abstract
With the development of economic society and increase of demand for electricity,the development of high current solid switchgear cabinet has become a hot topic at present.In this paper,a certain type of high current solid switchgear cabinet is taken as the research object,and the temperature-flow field of its three-dimensional model is simulated through the finite element simulation software.For the simulation analysis,the epoxy resin with different thermal conductivity is used,the temperature rise distribution of the solid switchgear cabinet before and after optimi-zation of heat dissipation air duct is optimized and effectiveness of the simulation method is compared and verified through type test.The research result shows that the heating parts of the solid switchgear cabinet are concentrated in the upper adapter,moving contact,T-type conductor,flexible connection and the dynamic and static end of the vacu-um bulb,in which the dynamic end of the vacuum bulb has the highest temperature.After the optimization of the sol-id switchgear cabinet,the airflow velocity in the cabinet is increased and the temperature rise of the heating spot is greatly reduced.The research results provide a new method and idea for the development of high current solid switch-gear cabinet.关键词
