| Abstract: | A hydrogen-explosion event of one 600 MW hydrogen-cold generator took place in an electric power plant.Direct-current withstand voltage test was carried out after the gas-exchange operation was over for two days,when the first phase test was finished,the voltage was step down to zero and the windings were earthed,this event happened.Through the analysis to the generator structure and the investigation to the event process,the possible hydrogen source and fire source was deduced,and the measures to prevent such event from happening were given. |
