　　劉家峽水電廠330千伏開關站配電裝置采用戶外GIS設備，其各項技術性能均達到了國內外同行業的先進水平。一是變壓器采用SSP－315000／330GY型變壓器，運行噪音低、局放小、總損耗降低了3／7左右。二是配電設備采用全封閉組合電器，緊湊，減少了對周圍建筑物及設施的影響，可靠性高，檢修維護量小，檢修周期長。三是開關站與變壓器之間的連接采用SF6氣體管道，用330kV交聯聚乙烯電纜相連接，技術先進，可靠性高，更利于防火，運行穩定、可靠。四是監控系統采用開放系統總線式網絡，軟件模塊化、結構化的設計，人機界面功能強、操作方便、簡潔、靈活，采用國際通用的系統集成思想，實現管控一體化，大大提高電廠的自動化水平。
