摘要
通过对柘林水电站大坝安全监测自动化系统中雷击事故处理措施进行分析,指出了该系统在防雷措施方面存在的不足,介绍了一系列提高系统防雷能力的措施:对传感器电缆加装屏蔽层、用太阳能电池给测控单元供电、增加接地引下线的截面积、采用直流光端机通讯等。
Based on analysis on lightning accident of safety monitoring automation system,deficiency of the system were put forward.Moreover,measures to improve lightning protection capabilities were carry out： installing the shielding layer on the sensor cable,using solar battery power supply for the MCU,increasing the ground deflectors＇s cross-sectional area,using DC optical fiber modem to communication.
