灯泡贯流式水轮发电机通风冷却方式概述

Overview of Ventilation and Cooling Method of Bulb Tubular Turbine Generator

随着灯泡贯流式机组技术的不断发展以及国内外对低水头电站的不断开发,大型灯泡贯流式水轮发电机组的市场需求越来越大,机组容量也相应增大。由于灯泡贯流式机组的结构形式,发电机的通风冷却是限制灯泡贯流发电机容量的关键因素,本文介绍几种灯泡水轮发电机的通风冷却方式。

With the technology development of bulb tubular hydraulic generating unit and the continuous exploitation of low-head hydro power station in both domestic and overseas market,there is increasing market demand for huge bulb tubular hydraulic generating unit,and the capacity of the units increases correspondingly. Due to the mechanical structure of the bulb tubular hydraulic generating unit,the ventilation and cooling method of the key factor to limit the capacity of bulb tubular generator. This paper introduces several ventilation and cooling methods of the bulb type generators.
