- 摘要：
- Abstract- Multi-cathode-spot ac arc extinguishing
process in vacuum interrupter is shown. It is divided
into 4 periods, arc transient state period, sheath
developing period, metal vapor decaying period and
static state period. The first 3 stages are dynamic
physical processes and their mathematical models are
given. Residual resistance in sheath developing period
and metal vapor density in metal vapor decaying period
can be obtained by solving the mathematical equations
and the 2 parameters are used to evaluate the
interrupting capability of a vacuum interrupter. In
current interrupting process, if residual resistance keeps
rising and metal vapor density is less than the critical
one, the vacuum interrupter can interrupt the current
successfully.
