摘要

高落差垂直竖井GIL隔室设置主要考虑因素是压力差

隔室压力差可用气体静气柱理论计算。通过对工程设计研究和理论计算表明:纯SF6气体的隔室高度不宜超过250m

SF6混合气体压力差较小

对隔室高度影响较小;因压力差的影响

对高落差垂直竖井GIL应规定两个充气压力;考虑温度差是压力差的主要影响因素

应重视竖井通风设计。

Abstract

The main considering factor of arrangement of GIL compartment in high drop vertical shaft is pressure difference which can be calculated by theory of static gas column.Through the engineering design studies and theoretical calculations

it shows that the height of pure SF6 gas compartment should not be more than 250 m

and the less pressure difference of SF6 mixture gas has less impact on the height of GIL compartment.It should provide two inflatable pressures for high drop vertical GIL shaft due to the influence of pressure difference.Considering that the temperature difference is the main influencing factor for pressure difference

it should pay attention to ventilation design of shaft.
