摘    要:针对电涌保护器(SPD)级间能量配合试验中配合失效的问题,主要利用波的传输理论与基尔霍夫定律进行分析,结合JB/T 10618-2006(组合式电涌保护器)的规定假设一套组合型SPD,通过基础理论分析与精确计算得出:当被保护装置属于低频(直流)设备时,在不影响信号强度的情况下,退耦元件采用电感或电阻型元件均可;当被保护装置属于高频设备时,退耦元件只能选用低电感量的电阻型退耦元件.退耦元件的参数值均可按照波的传输理论与基尔霍夫定律进行理论计算.这在组合型SPD退耦元件的选型过程中,具有重要的指导意义.

关 键 词:电涌保护器  退耦  传输理论  基尔霍夫定律  选型

Abstract:This paper addresses the failed energy cooperation in experiment of muti-level Surge Protective Device (SPD).In accordance with the requirement of JB/T 10618-2006,a model of muti-level SPD is constructed and analyzed by transmission line theory and Kirchhoff law.Theoretical analysis and precise calculation show that resistance or inductance type of decoupling component works well when the protected equipment is working in status of low frequency;while only resistance type of decoupling component with low inductance should be selected when the protected equipment is working in status of high frequency.The value of decoupling component parameters could be calculated by transmission line theory and Kirchhoff law.It''s helpful for designer to choose an applicable decoupling component for multi-level SPD.
Keywords:surge protective device  decoupling  transmission line theory  Kirchhoff law  type selection
