Abstract

Air switchgear is the most widely used switchgear in power grid.Long-term high temperature rise will lead to the degradation of insulation and mechanical properties

even resulting in casualties.In order to analyze the temperature distribution characteristics of the heating fault of the air switchgear

the finite element simulation software is used to establish a 1:1 model and carry out the electromagnetic-flow-thermal multi-physical coupling simulation.The gas velocity

the surface temperature distribution

the internal temperature field distribution and the shell temperature distribution of the air switchgear under different heat source power are compared and analyzed.The distribution law of different heat source power is summarized

which lays a theoretical foundation for judging the internal fault of the switchgear based on the distribution of the surface temperature field of the switchgear

and provides a reference for simulation.
