摘要
为满足目前高电压开关设备小型化的需求,笔者以145 kV小型化的SF6气体绝缘复合套管为研究对象,基于标准和工程的技术要求,建立整体套管的物理模型,对套管的内外绝缘设计分别进行计算分析,并采用有限元法对套管电场进行分析,确定了145 kV小型化气体绝缘复合套管的绝缘结构设计。通过对样机的试验验证,证明了该小型化套管设计方案合理,各项性能指标均能满足预期要求,具有良好的技术经济指标。
To meet the need of miniaturization mini-bushing was taken as the design object, of HV switchgear, 145 kV SF6 gas insulated composite and a physical model of the whole bushing was built according to the requirements of the standard and engineering. The internal and external insulations of the mini-bushing were calculated, and its electric field was analyzed by the finite element method to determine the insulation structure. Test miniaturization design of the 145 indexes are satisfactory. was conducted on the prototype, and kV SF6 gas insulated composite bushing the results indicate that the is rational, and all performance
