According to the relationship between the energy dissipation of SiC demagnetizing resistance and the maximum temperature rise under the large and small energy shocks obtained from the demagnetization test of SiC demagnetizing resistance, a new method is proposed to measure the quality of off-line energy shock temperature measurement by introducing SiC demagnetizing resistance components Method to measure the temperature rise of each part of the SiC component surface to calculate the surface temperature coefficient, check the SiC demagnetizing resistance component has the existence of individual material is not uniform, there are serious quality defects in the SiC sheet, timely treatment to ensure that the generator of a serious accident demagnetization Safety, for demagnetizer design, bidding, operation and maintenance reference.
