Research on Positioning System of Insulator String Flashover in High Voltage Transmission Line

Abstract:

Considering that insulator flashover accident frequently occurs in high voltage transmission line, a kind of insulator string flashover positioning system is designed. The positioning system is on based on the fact that ultrasonic and ultraviolet energy is released when flashover occurs. To make sure whether a flashover accident occurred, sensors are used to detect ultrasonic and ultraviolet waves near the insulators in real time. The detecting results and accident position information will be uploaded to the monitoring center wirelessly using GSM/GPRS (Global System of Mobile communication / General Packet Radio Service), which can make it easy and fast for operating personnel to locate the accident, reduce troubleshooting work and quickly recovery power transmission. The experiment shows that the system has lots of advantages such as high sensitivity, high positioning accuracy, more stable and so on.
