Expressway toll station is listed by lightning protection experts as one of the five difficult problems in the field of international lightning protection. So far, the direct lightning protection of the expressway toll station is mainly based on the electrical geometry model-rolling ball method. Lightning rod or lightning belt is installed on the high pole lamp of the toll square and the ceiling of the toll island as a flash catching device to intercept lightning. The lightning rod is a section of metal conductor with the tip. From the process of the connection between up leader generated by the lightning rod and down leader of lightning, the lightning rod has the ability to attract the lightning rod, and can prevent lightning strike of the protected objects within a certain range. From the perspective of lightning protection methods and means, lightning protection plays an interception role against lightning discharge, also called interceptor. A large number of practice has proved that the lightning rod plays an important role in protecting the building structure from lightning damage. With the development of electronic information society, the limitations of lightning rod are more and more prominent, resulting in more and more lightning strike accidents. In 2019, China invented a new flash connection device-lightning interceptor that can overcome the limitations of lightning rod and has applied it on expressways, which has achieved remarkable results. In this paper, the physical parameters of lightning receiving process by the lightning interceptor and the lightning rod are compared, and the solution to prevent direct lightning strike at expressway toll station is proposed.
