Fault Analysis of Phase-change Defect of the Converter Valve Set Caused by Mistrigger
The paper aualyzes phase-change fault cause of the converter valve set for a certain convertor station.By warning analysis,phase-change and phase-change process analysis,find out that electromagnetic interference or trig-ger eircuit plate block abnormal to make the converter valve mistrigger,thus causing phase-change defect.The fault prompts us to think highly of controling main machine program optimization,renew and maintain electromagnetic screen in time,avoid elements and trigger blocks to make the converter valva mistrgger when metastable state ap-pears.
