摘要
结合目前电涌保护器后备保护装置(SCB)的现状,提出一种智能型SPD专用保护器的设计结构,其保护性能高,并实现其全生命周期的运行监控,提高了低压配电系统的安全性及运行可靠性。
Combining with the current status of SCB,a design structure of intelligent surge protective device(SPD)special protectors is proposed,which has high protection performance,and realizes the operation monitoring of its full life cycle.It can improve the safety and reliable operation of low voltage power distribution systems.
