摘要
为在试验室环境下模拟SF_6气体绝缘交流GIS装备在正常、故障运行条件下的各项性能参数,并能定时、定量跟踪监测局部放电量、SF_6气体分解物等特征参量的发展趋势,设计并研制了220kV SF_6气体绝缘GIS真型试验平台,即从GIS中心母线、固体绝缘件结构设计出发,仿真分析了固体绝缘件三维电场分布特性,并对220kV GIS真型试验平台进行了调试,验证了GIS中心母线、固体绝缘件结构设计的可行性,为现场用在役SF_6气体绝缘GIS装备运维检修提供一定理论和实践依据。
To simulate the performance parameters of SF6 gas insulated AC GIS equipment under normal and failure conditions in the laboratory environment,and the development trend of characteristic parameters such as partial discharge and SF6 gas decomposition can be monitored periodically and quantitatively,the 220 kV SF6 gas insulated GIS type test platform was designed and developed.Starting from the design of GIS bus and solid insulation structure,three-dimensional electric field distribution characteristics of the solid insulator were simulated and analyzed.Through design and development of 220 kV SF6 gas insulated GIS type-test platform,the feasibility of the structure design of GIS bus and solid insulation were verified.Thus,it can provide theoretical and practical basis for the operation and maintenance of SF6 gas insulated GIS equipment.
