摘要
根据通信导航设备在雷击中的损坏现象,提出了电源防雷措施,即实施分级保护,在多雷区配置防雷变压器。简单介绍了级间配合,抑制横向过电压的产生,以及接地阻抗的简单计算和正确选用等,以达到对电源系统的有效防雷保护。
According to the damage events of the communication & navigation equipments of CAAC under lightning strike, it presents lightning protection. Measures of the power supply--to implement graded protection, to place the isolating transformer in the multi-lightning area. The paper describes the coordination of the multi-grade surge protection, the suppression of the transfer over voltage, as well as the calculation and selection of the impedance of the grounded wire for effective lightning protection of the power supply.
