气体绝缘全封闭组合电器应用于发电厂变电站的技术经济分析

Technological and Economical Analysis on GIS Appling in Power Plant and Transformer Substation

结合气体绝缘全封闭组合电器在国电石嘴山发电厂2×330 MW机组技改工程中的应用效果和经验,经过技术、经济两方面的综合评价,认为GIS的采用,大大降低了工程造价,确保了地区电网和公司机组的安全可靠运行,对电力生产起到了重要作用,取得了良好的社会效益。

Through the integrating evaluation on the technology and economy according to the applying effect and experience that the GIS apply in the 2×330WM generation units technology reconstruction of the state power company Shizuishan power plant, this paper considered that the GIS decrease largely the engineering cost, and ensure the safety and reliability of the area grid and power generation units. The use of GIS has gained a well societal benefit.
