Abstract

The invention discloses a laser-powered GIL breakdown fault positioning system which comprises a laser energy supply unit, an ultrasonic sensor array, a fault positioning and monitoring IED array and a background monitoring unit. The laser energy supply unit comprises a laser power supply base station, a laser power supply energy receiving module and a power supply management and control module. According to laser power supply, energy is transmitted through optical fibers in a laser mode, isolation between high potential and low potential is achieved, good safety is achieved, and the reliability of a fault positioning result is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrician detection, in particular to a laser-powered GIL breakdown fault location system and method. Background technique [0002] Gas-insulated transmission lines (GIL) is a kind of compressed insulating gas (such as SF 6 , N 2 etc.), the power transmission equipment coaxially arranged between the casing and the conductor has the advantages of high voltage, high current, flexible layout, stable operation, and small interaction with the environment, and is widely used in power systems. [0003] GIL adopts a fully sealed design with large air chamber and long pipeline. If an arc breakdown fault occurs during operation, it is necessary to quickly and accurately locate the fault location and repair it in time, otherwise it will seriously affect the stable power transmission of the entire transmission line and affect the power system. have a huge impact. [0004] When a GIL arc fault occurs, a current p...
