【Abstract】 The current, energy and V-A characteristics of SiC de-excitation resistance for 600 MW generator were provided. The relation between the maximum surface temperature and consumed energy of SiC resistance was presented based on these characteristics that got from a lot of experiments. Opinions about the effect of the negative temperature characteristic and maximum energy test were also presented. At the end, the suggestions were given for the quality control and application security of SiC resistance.更多还原
