摘要
针对组合型电涌保护器(SPD)中主要防雷元件之间的能量配合问题,依据IEC 62305-4与GB 50343—2010的规定要求,通过对气体放电管(GDT)、金属氧化物压敏电阻(MOV)、瞬态抑制二极管(TVS)进行理论概述,再对这3种常见的防雷元器件进行并联组合后,分别进行多次冲击实验,发现不同的防雷元件的合理并联配合使用对于提高SPD整体的响应速度,缩短动作过程时间,提高SPD的通流容量与限压水平具有明显的效果.实验结论对于组合型SPD的设计具有一定的实际参考价值.
The energy coordination between main lightning protective components is an important issue in the combined Surge Protective Device（ SPD）. The principles of Gas Discharge Tube（ GDT）,Metal Oxide Varistor（ MOV）,and Transient Suppression Diode（ TVS） are analyzed theoretically,and then the three kinds of components were combined in parallel connection,and tested by impact experiments,in accordance with the specifications and requirements of IEC62305 and GB50343—2010. The results show that reasonable parallel combination of different SPD components has a significant effect on improving the overall response rate,shortening the action progress time,increasing the flow capacity and limit voltage level. The conclusions have practical values for the design of combined SPD.
