摘要：
A circuit including source and vacuum interrupter is taken into consideration as calculated model. The steep-fronted transient over-voltage curve between contacts of vacuum interrupter caused by current chopping and reignition is calculated Three main frequency components of the steep-front transient over-voltage are obtained from Discrete Fourier Transform (DFT), which are regarded as boundary excitation. The differential equations of transient field are established and FEM is adopted to calculate the transient electric field of vacuum interupter. The distribution curves at representative time are investigated, which are compared with the one in the static field. The electric field intensity distribution curves are also given in this paper Some distinguishing features of the transient field are also discussed.
