Abstract

For the complexity of actual product structure, the three dimensional electric field finite element model of KYN-40.5kV high voltage metal enclosed switchgear was built and analyzed by using subarea modeling and partial thinning mesh. The calculation results show the distribution of the internal electric field of the switchgear and the concentrate parts of electric field are pointed out. The concentrate parts of electric field, such as the location of wall bushing and contact box, are analyzed. By numerical simulation techniques, the effect of insulating spacers, grading rings and shield cases on the local electric field distribution was analyzed, the corresponding sections were optimized. The finite element model for the lap joint and bolts of the busbar in switchgear was build up. Through quantitative analysis, the maximum number of exposed threads of bolt has been obtained as to the different distances between the busbars. These results provide certain valuable reference on improving the electric field distribution in the switchgear, increasing insulation level and guiding on-site maintenance.
