复杂环境下中波发射台防雷接地系统设计

Design of Lightning Protection and Grounding System for MW Launching Station in Complicated Environment

我国部分地区雷电灾害频发,尤其是广播塔、中波发射台等区域,一定程度上会造成经济损失,因此,要对复杂环境下中波发射台防雷接地系统进行设计。设计I/O接地控制模块,并关联反控复合电路,完成硬件的设计,随后,构建总控功能模块,接入接引指令,完成软件的设计。最终系统测试结果表明:在相同的环境之下,对不同雷击电压的复杂环境下,系统的报警时间进行测算。经过汇总整合,报警的时间均保持在0.5s以下,表明系统在执行任务的过程中控制检测的效果相对较好,具有实际的应用价值。

Lightning disasters occur frequently in parts of our country,broadcasting towers and MW transmitters are lightning-hazardous areas,which will cause economic losses to a certain extent.Therefore,the lightning protection and grounding system of medium wave transmitting stations in complex environment is designed.The I/O grounding control module is designed,and the anti control composite circu it is associated to complete the hardware design;then,build the main control function module,access the connection instructions,and complete the software design.The final system test results show that the alarm time of the system is calculated under the same environment and the complex environment with different lightning strike voltages.After summary and integration,the alarm time is kept below 0.5s>which shows that the control and detection effect of the system is relatively good in the process of performing tasks;and has practical application value.
