摘要
介绍了电源防雷器与被保护设备电压保护水平配合原则,用行波理论分析了多级电源防雷器级间采用自然阻抗或退耦元件实现能量配合的具体方式,可直接应用于防雷工程实践,从而保证电源防雷器雷击瞬间逐级正常启动,将威胁设备的电涌电流泄放衰减到被保护设备能承受的安全范围内。
The paper introduces the coordination principle between the multipower surge protector and the voltage protection level of protected equipment.Analyze the special ways to realize the energy coordination of the multi-power surge protector,adopting natural resistance or decoupled components using traveling wave theory.The ways can be directly applied to engineering practice,so as to guarantee the multi-power surge protector gradually started.The surge current is attenuated so that the equipments are able to accept.
