de,浇gP口05}〕一,l飞LJ{1 LJI、f。(」1‘lr乃]-灯泡式水轮发电机(bulb type hydrogen-erator)将发电机与轴承等布置在形似灯泡的密封壳体内的水轮发电机。灯泡式水轮发电机与水轮机直轴连接并布置在水下流道内,其特点是结构布置紧凑、复杂,具有防潮防漏等特殊要求。由于灯泡式水轮发电机装在水下,停机时绕组容易受潮,为了安全可靠,发电机额定电压选择比一般水轮发电机低。 灯泡式水轮发电机因受灯泡比的影响,一般发电机直径较小,因此转子励磁绕组极间空间位置也小.励磁安匝数受到限制,故选用较高的功率因数。此外.灯泡式机组的水轮发电机转动惯量及惯性时间常数较小,故机组甩负荷时的转速上升率月值较大,一般大于45%,飞逸转速可达额定转速的2.5一3.5倍。与同容量立式水轮发电机相比,水轮机的转轮直径可缩小,因此灯泡式机组额定转速可提高1。%以上.发电机内径可减少25%以上,整个机组的重量(包括水轮机)可减轻25%,是较经济合理的一种机型,多用于工作水头范围为3一25m的低水头水电站。灯泡式水轮发电机组结构剖面见图示。 灯泡比定子机座外径与水轮机转轮外径的比值称为灯泡比。它是灯泡式水轮发电机组的一个重要特征参数,通常取0.9一1.2。灯泡比过大将使水轮机的水力特性变坏,机组效率降低;灯泡比过小将使铁芯长度增加,转动惯量减小,甩负荷时转速上升率增大,对通风散热不利。 冷却方式灯泡式机组由于转速低、直径小、定子铁芯长度大,采用常规的自然通风冷却方式很难满足要求,因此需要采用带有风机的强迫循环轴向或轴、径向通风冷却方式。此外.还可采用定子铁芯贴壁冷却或增压冷却。贴壁冷却是定子铁芯采用贴壁结构.利用水流带走灯泡体散发的热量。增压冷却是在灯泡体内充 压,增强散热能力.可提 高机组的综合效率和降 低灯泡比.但需增设充 压设备和提高泡体的密 封性能,并对运行人员 进人泡体内检查维护带 来不便,通常增压的最 优压力可取2()()一30(〕 kPa。 发展简史”:访年 瑞士设计了第一台灯泡 式水轮发电机,装在路 斯汀(R()、r.n)水电站。50___、。、,.,~二年代,法国、日本、前苏联、娜威等国家建成一批灯泡式水电站。
