The Use of the Induced Voltage in the Ground Wire for Electric Transmission Line

本文通过对输电线路避雷线上感应电压和感应电流的产生机理,提出了多种利用方式。加装电流检测装置,可及时监测线路断线,进行维修,保障恶劣天气时避雷线有效防雷;通过并联方式,在输电线路中途借用避雷线感应电压提供电能,添加整流装置和稳压措施,为保护和控制系统提供直流操作电源;为去污装置提供驱动,利于绝缘子去污,提高系统的耐雷水平;同时补充了避雷线防盗,提供线路照明的功能。这些多元化的功能实现,将为电力系统带来更多便利和实效。

In this paper,it analysizes the principle of the induced voltage and current in the ground wire for electric transmission line,and gives numerous ways to use the voltage.To add current detection device, it can monitor the disconnected state of line for maintenance. When it＇s bad weather, the ground wire can be effective in lightning protection. Through the parallel manner, the induced voltage in the ground wire provides power in the middle of transmission line, and it adds rectifier devices and regulators to provide DC operating power for the protection and control system. To drive the decontamination devices,it helps insulators＇ decontamination to improve the resistance level of lightning. At the same time, it complements the anti-theft ground wire and provides lighting for transmission line.To accomplish, such a wide range of function will bring more convenience and effectiveness to the power system.
