摘要
气体绝缘金属封闭开关设备(GIS)是电力系统的基础设备,随着电网建设的迅速发展,其重要性不断提升。热伸缩波纹管作为GIS运行过程中的重要部件,多用于现场GIS的安装与拆解、环境温度变化产生的热伸缩的吸收以及基础不均匀沉降的调节等。本文从某电压等级热伸缩波纹管设置距离入手,通过仿真解析确定热伸缩波纹管设置原则,进而计算出热伸缩母线长度,最后对热伸缩波纹管参数进行详细设计分析,为其他热伸缩波纹管参数设计提供参考。
Gas insulated switchgear(GIS)is the basic equipment of the power system,with the rapid development of power grid construction,its importance continues to increase.As an important component in the operation of GIS,thermal expansion bellows are mostly used for the installation and dismantling of on-site GIS,the absorption of ther⁃mal expansion caused by changes in ambient temperature and the adjustment of uneven foundation settlement.This paper started with the setting distance of the thermal expansion bellows of a certain voltage level,determined the set⁃ting principle of the thermal expansion bellows through simulation analysis,and then calculated the length of the ther⁃mal expansion bus,finally carried out a detailed design analysis of the thermal expansion bellows parameters to pro⁃vide a reference for the parameter design of other thermal expansion bellows.
