摘　　要：介绍了开关型SPD典型的3种触发技术,比较了各自的特点,并根据栅片灭弧结构的特点,提出新的触发技术——多点火花触发。详细描述了所提出的触发技术的工作原理及过程,最后通过试验进行了验证,证实了"多点火花触发"的可行性。The three typical trigger technologies of switching SPD were introduced and their features were compared. The new trigger technology, multi-spark trigger were put forward according to the characteristic of splitter arc chamber structure. And the principle and working procedure of trigger technology were described in detail. Finally, the practicability of the multi-spark trigger technology was demonstrated by simulation test.
