随着通信技术的不断发展,我国民航通信导航事业也在不断地向现代化迈进。目前,民航通信导航设备大都采用大规模集成电路及晶体管。这些元器件对输入输出端口、电源等部件的技术指标和工作环境提出了更高的要求。由于抗过压、抗过流能力弱,即便是幅度低、时间短、能量小的雷电感应浪涌都可能造成这些元器件的损坏。所以,传统的避雷针技术已无法满足目前民航通信导航设备的防雷避雷要求。
With the continuous development of communication technology, China’s civil aviation communications and navigation business is also constantly moving toward modernization. At present, most civil aviation navigation devices use large-scale integrated circuits and transistors. These components on the input and output ports, power supplies and other components of the technical indicators and working environment put forward higher requirements. Due to anti-overvoltage, anti-overcurrent ability is weak, even if the amplitude is low, short time, small energy lightning surge may cause these components damage. Therefore, the traditional lightning rod technology has been unable to meet the current requirements of the lightning protection and lightning protection of civil aviation communications and navigation equipment.
