摘要
阐述引起750kV和330kV GIS母线筒温度变化的因素,给出实际现场温度变化引起GIS母线筒长度变化的计算方法,合理解释了母线筒在青藏高原地区存在滑动支撑移动不到位等原因。
This paper describes the factors that cause temperature changes in 750kV and 330kV GIS busbar tubes,provides a calculation method for the length changes of GIS busbar tubes caused by actual on-site temperature changes,and reasonably explains the reasons for the sliding support and inadequate movement of busbar tubes in the Qinghai Tibet Plateau region.
