SF6替代气体技术及其在GIL中的应用与发展
SF6 Alternative Techniques and Their Applications and Prospective Developments in Gas Insulated Transmission Lines
摘要
Abstract
To some degree,SF6 alternative techniques play an important role in the development and application of GIL.Therefore,starting with the technique development of SF6 alternatives,we review the GIL history and the application of SF6 alternative technique in GIL.Combined with the current progresses of SF6 alternatives and GIL,some prospective studies on GIL are also discussed.Along with the breakthrough of SF6/N2 gas mixture technique,the 2nd generation GIL achieves successfully commercial applications,and SF6 alternatives have been actively explored.Alstom and ABB provided C4 FK mixtures and C5 FK mixtures,respectively,to replace SF6,causing widespread concerns.Moreover,Alstom carried out temperature rise test of C4 FK mixtures on a 420 kV GIL prototype,but the temperature rises are in the range of 10%~15% higher than that of SF6.It is shown that the 3rd generation GIL is still in the laboratory research stage.As the development of SF6 alternative technique and the improvements in GIL construction,the 3rd generation GIL,i.e.environmental friendly gases as dielectric gases,will possibly open a new age.关键词
