中波发射机的防雷与接地保护探究

Study on Lightning Protection and Grounding Protection of Medium Wave Transmitter

现阶段,中波发射机在我国广播电台领域内的应用较为广泛,发射机运行稳定性控制与广播信号的传输质量之间存在密切关联。纵观当前中波发射机系统的运行,在雷雨天气下极易遭受雷击,进而对发射机安全运行造成威胁。为了避免雷击灾害对中波发射机的运行造成影响,需要结合发射机结构特点采取针对性防雷与接地保护措施,以提升中波发射机抗雷电侵袭、抗干扰等能力,避免因雷击导致发射机故障瘫痪而出现巨大经济损失。目前,加强发射机防雷与接地保护已经成为广播电视单位的关注重点,对此从雷击对中波发射机造成危害影响的分析入手,并在此基础上阐明发射机防雷与接地保护措施的具体应用。

At this stage,the application of medium-wave transmitters in the field of radio stations in China is more extensive,and there is a close relationship between transmitter operation stability control and the transmission quality of broadcast signals.Looking at the current operation of the medium-wave transmitter system,it is extremely vulnerable to lightning strikes in thunderstorms,which in turn poses a threat to the safe operation of the transmitter.In order to avoid the impact of lightning damage on the operation of the medium-wave transmitter,it is necessary to take targeted lightning protection and grounding protection measures in combination with the structural characteristics of the transmitter to improve the ability of the medium-wave transmitter to resist lightning invasion and anti-interference,and to avoid huge economic losses due to the failure and paralysis of the transmitter due to lightning strikes.At present,strengthening the lightning protection and grounding protection of transmitters has become the focus of attention of radio and television units,starting from the analysis of the harmful effects of lightning strikes on medium-wave transmitters,and on this basis,the specific application of transmitter lightning protection and grounding protection measures is clarified.
