摘要
通过分析浪涌保护器的原理、作用及保护等级,阐述了在低压配电系统中浪涌保护器的设计与选择原理,使设备免受雷电电磁脉冲的破坏,达到保护设备的目的,同时也为电气设计人员提供了理论依据。
The theory, effect and protection class of surge protective device were analyzed, and the design and choice of surge protective device in low voltage power distribution was described.It kept the electric equipment away from the damage of lightning electromagnetic pulse, achieved the purpose of protection, and proposed theory reasons for the electrical designer.
