摘　　要：截至2019年底,广东高速公路通车里程达9495公里,全省高速公路路网日臻完善,带动了粤中东西北区域经济发展,同时也为人民生活出行带来了美好的交通便利,这其中也离不开高速公路机电系统发挥的作用。高速公路机电设备种类多、数量广,其分布具有点多、面广、线长的特点,运行状态易受周边环境和气候影响,个别地区设备还容易受到雷电侵袭。如果设备受到雷电侵袭,有可能会导致设备出现故障,甚至还可能会导致高速公路的整个机电系统瘫痪,影响高速公路营运工作。因此高速公路建设和营运都必须高度重视机电设备的防雷接地工作。By the end of 2019,the mileage of Guangdong expressway has reached 9495 kilometers,and the highway network of the whole province has been improved day by day,which has led to the economic development of the northwest region of Guangdong and the Middle East,and has also brought good transportation convenience to the people,which can not be separated from the role played by the mechanical and electrical system of the expressway.There are many kinds and a wide number of mechanical and electrical equipment in expressway,and its distribution has the characteristics of many points,wide area and long line.The operating state is easy to be affected by the surrounding environment and climate,and the equipment in individual areas is also vulnerable to lightning attack.If the equipment is attacked by lightning,it may cause the equipment to malfunction,and even cause the whole electromechanical system of the expressway to be paralyzed,which will affect the operation of the expressway.Because of this,the highway construction and operation must attach great importance to the lightning protection grounding of mechanical and electrical equipment.
