A steam turbine A transformer trip accident causes analysis and treatment

Abstract

Abstract:

Abstract:After analyzed the incident of Huadian Laizhou Power Generation Company Limited 1000MW ultra critical unit steam turbine A transformer trip,the author indicated that the transformer low voltage side outlet busbar is too close to power distribution cabinet,and caused flashover and A transformer protection trip. Treatment measurements and matters need attention while power recovery was indicated. 

Key words:

Keywords:steam turbine, transformer, fast differential over current protection, busbar, flashover
