摘要
电涌保护器(surge protection device)是一种保护装置,对保护电子设备起到至关重要的作用。它能把电子设备中的过电压控制在可承受的范围内,还能抵御冲击电流的冲击,防止电子设备因此而发生损坏。长期工作电压的积累或者短时冲击电流的冲击,SPD不可避免地会发生老化现象,若发现不及时,会对设备产生严重后果。归纳分析了中外学者对SPD老化机理的观点及实验进展,SPD老化程度的检测以及加强SPD稳定性能的手段。
Surge Protective Device is a protection device, referred to as SPD, it plays an important role in the protection of electronic equipment . It makes the transient over-voltage which put into the electronic equipment limit in the acceptable range and withstands the impact of the shock current. It protects electronic equipment from these damages. However, due to the accumulation of long-term working voltage or the impact of short term shock current, SPD will inevitably lead to aging, if not found in time, electronic equipments will have serious consequences. This paper summarizes the domestic and foreign scholars on the aging mechanism of SPD and its research progress, the detection of SPD aging degree and the method of improving the stability of SPD.
