Abstract

Abstract: The reformation necessity of cooler of main transformer No.2 in Shitang Hydropower Station was introduced, the reformation scheme was described. The cooling effects of main transformer No.2 cooler before and after reformation were compared. The temperature variations of main transformer at 2006 year and 2007 year under typical operation condition were compared. The cooling effects under different condition during cooler reformation process were analyzed, and the perfections were accomplished stage by stage, so the optimum economic effect of the reformation project was obtained.

Key words: main transformer, cooler, reformation measure, heat dissipation effect, economic analysis
