Abstract

Gas-insulated mental enclosed transmission Line(GIL) as an overhead transmission mode or a supplementary transmission technology with limited transmission point of cable, has the advantages of large capacity, less space, flexible layout and high reliability. In view of the operating characteristics of UHV GIL, in order to ensure its safe and stable operation, an arc fault monitoring system is deployed inside the GIL tube corridor. The energy acquisition mode of the arc fault monitoring system is mainly studied in this paper. Based on the angle of high and low potential isolation, security and practicality, a scheme of laser optical fiber power supply and communication for UHV GIL arc fault monitoring is proposed, which provides stable and reliable energy supply and communication guarantee for arc fault location and monitoring equipment, and provides support technology for safe and stable operation of UHV GIL.
