爲滿足GIS間隔擴建對接安裝及交接耐壓試驗時運行母線不停電的需求,文中介紹了一
種具備雙隔離斷口操作,並能夠確保雙隔離斷口中間導體有效接地的新型功能模塊。文中首先
比較了新功能模塊與傳統母線隔離開關模塊的原理接線的性能特點,從殼體鑄造、機械傳動、
內部結構以及電場分布等方面進行闡述與分析,最後提供了模塊的工程應用實例。GIS備用間隔
采用該模塊作爲母線隔離開關後,可以有效避免擴建安裝以及交接耐壓試驗時斷口擊穿以致系
統短路接地的風險。另外,該功能模塊可大幅度降低GIS氣室對接安裝過程中的作業風險,大幅
節省了SF6氣體的充放處理時間,有效提高工作效率。

It is desirable that the busbars can continue operating without shutting
down during GIS extension and withstand tests. In order to meet this requirement,
a new structure has been developed in this paper. The structure has double
isolating distance and a function of earthing the middle conductor connected
between the double breaks effectively. The comparison between the proposed GIS
structure and the conventional GIS structure with bus disconnector is made. Further
, the shell manufacturing, mechanical movement patterns, the interior structure
as well as the principle of contacting are involved as well. Lastly, the
installation instruction of the new structure in the field is introduced. The risk
of ground faults caused by the breaks breakdown in the procession of the GIS
extension and the commission withstand tests can be largely avoided with the new
structure installed as the disconnector of a busbar. Besides, this structure can
also evidently reduce the operational risk during the joint installation of GIS
chambers and save the processing time of filling and releasing SF6 gas, which aids
to largely improve the working efficiency.
