H级绝缘系统在大型汽轮发电机中的应用

Application of H Class Insulation System in the Large-size Turbine Generators

分析了耐热等级对大型汽轮发电机的影响,比较了国内外主要标准对汽轮发电机热点温度的要求,认为国家标准对汽轮发电机热点温度要求更严格,提出若采用H级绝缘系统后,可以提高大型汽轮发电机的可靠性与经济性。并着手探讨H级绝缘系统考核与评定的原则。

Influence on the large-size turbine generators by the heat resistant class of insulation was analyzed while different requirements on the hot spot temperature at home and abroad were compared,considering that the requirement of the hot spot temperature in the national standard is more serious than that of abroad.Points of view that reliability and economic of the large-size turbine generators might be increased a great deal was raised in case of the H Class insulation being applied and Principe to examine and evaluate the H Class insulation system was getting on.
