摘　　要：开关型SPD上在实际生产中有着广泛的应用,为了克服这种SPD本身的缺点,国外厂家提出了很多新的技术,本文在此基础上提出了一种新型的开关型SPD续流遮断技术,并详细介绍了这种新型开关型SPD续流遮断技术的原理及设计方案,此种技术的应用主要有两大优点:1)有效提高了开关型SPD的续流遮断能力;2)无外泄电弧放电。Switching type SPD has a wide range of applications in actual production. In order to overcome the shortcomings of this kind of SPD, many new technologies have been put forward by foreign manufacturers, and on this basis, a new interrupt follow current technology is proposed, and this technology principle and the design proposal is introduced in detail, the application of the technology, has two major advantages： 1） improve the interrupt follow current capacity of switching type SPD; 2） without leakage arc discharge.
