Study on Leakage Detection of Environment friendly GIS Based on Isotope Tracing Technology
Gas Insulated Switchgear(GIS)plays a crucial role in maintaining the safe operation of the power grid and supporting the sustainable development of the national economy and society.SF6,known for its outstanding insulation and arc-quenching properties,has traditionally been the preferred insulation medium for GIS equipment.However,the increasing scarcity of resources,energy crises,and escalating environmental concerns have prompted a shift towards cleaner alternatives due to the high pollution and greenhouse gas emissions associated with SF6.Transitioning to environmentally friendly clean air presents new challenges for detecting leaks in GIS equipment as clean air closely resembles atmospheric conditions.This study utilizes gases and elements like He,CO2,18O,and 15N as tracers to assess their impact on the insulation performance of clean air GIS equipment.Furthermore,it delves into the theoretical framework and design considerations for leakage detection in clean air GIS equipment using isotope tracing technology,laying the groundwork for the development of an advanced online monitoring system for detecting GIS leaks in clean air environments.
