为了解决建筑物电源系统安装SPD的配合配置问题，本文根据现行建筑物电网的TT系统、TN系统、IT系统等典型供配电系统，结合现行电源SPD的安装方式及参数选型，针对Uc、Up、Iimp、过电流保护器等重要参数设备选择失当，SPD安装位置错误，所造成的电源SPD电气故障模式或保护失效，得出了现行电源SPD的配合配置失当问题，并初步提出了解决方法。
為瞭解決建築物電源繫統安裝SPD的配閤配置問題，本文根據現行建築物電網的TT繫統、TN繫統、IT繫統等典型供配電繫統，結閤現行電源SPD的安裝方式及參數選型，針對Uc、Up、Iimp、過電流保護器等重要參數設備選擇失噹，SPD安裝位置錯誤，所造成的電源SPD電氣故障模式或保護失效，得齣瞭現行電源SPD的配閤配置失噹問題，併初步提齣瞭解決方法。
