强干扰环境中的通信设备防护设计

Communications Equipment Protection Design in Strong Interference Environment

雷电干扰和电力系统故障引起的地电位升高会对通信设备造成危害。大气过电压保护目前已形成了多种方式和多级结构,本文讨论多种保护方案的具体设计和实现,重点研究工频过电压的防护问题。

The rise of the earth potential induced by the lightning interference and power system failure can be harmful to the communications e-quipment. Various and multi - stage atmospheric overvoltage protection solutions are available, and the specific design and implementation of multiple protection solutions are discussed, especially the issue of industrial frequency overvoltage protection.
