【摘要】 全空冷汽轮发电机结构简单,运行维护方便,但受限于空气的散热特性,其容量存在一个设计极限。哈电新研制的QFKN-412-2型全空冷汽轮发电机,额定功率350MW,最大连续出力385MW,是当前国内自主开发的最大容量全空冷汽轮发电机。本文介绍了QFKN-412-2型全空冷汽轮发电机电磁设计、总体结构设计、通风系统设计、转子动力学设计以及型式试验结果。更多还原

【Abstract】 Full air-cooled turbo-generator has a simple structure and is easy to operate and maintain. However, due to the heat dissipation characteristics of the air, there is a design limit for the capacity of full air-cooled turbo-generator. The QFKN-412-2 full air-cooled turbo-generator developed by HEC has a rated active power of 350 MW and a maximum continuous active power of 385 MW. It is the largest full air-cooled turbo-generator currently independently developed in China. This paper describes the electromagnetic design, overall structure design, ventilation system design, rotor dynamics design and type test results of the QFKN-412-2 full air-cooled turbo-generator.更多还原
