QF-3-2型汽轮发电机说明书? QF-3-2型 发电机 转子线圈,转子铁芯,定子线圈,定子铁芯各有什么用? QF-3-2型发电机转子线圈的作用就是提供励磁电流,定子线圈则是感应三相交流电,转子铁芯和定子铁芯的作用是为发电机提供磁路的通路。 QF-3-2型发电机的同轴励磁机器有什么用? QF-3-2型发电机的同轴励磁机器是提供励磁电流使发电机的转子能够产生磁场,从而使发电机定子绕组能够发电的。 励磁线圈的作用是什么? 作用是为励磁机提供励磁电流的,使励磁机能够发出电压并向发电机提供励磁电流。 发电机非同期并网有什么危害? 危害主要是造成有功环流,将使发电机产生很大的机械冲击,严重时发电机将受到很大机械力而遭毁坏。 变压器接线组别不同而并列的情况是不是危害最大? 变压器接线组别不同而并列的情况与变压器并列的几个要求不能满足比较,其危害性一般来说是最大的。因为,冲击最大,破坏性也最大。 感性无功和容性无功是怎样产生的?为什么感性无功能去磁容性无功能加磁? 为什么发电机转速不变时能"有功调频,无功调压"? 感性无功和容性无功的产生与能量的暂时储存性质有关,消耗感性无功时,元器件是将电能以磁场的形式暂时储存,消耗容性无功的元件,则是将电能以电场的形式暂时储存。感性无功与容性无功的去加磁主要与其电枢反应的性质有关。感性无功产生的电枢磁场具有滞后性质,其对应的电枢反应具有去磁性质,这可从相量图中进行分析。同样道理,容性无功电枢磁场具有超前性质,其对应的电枢反应具有加磁性质。 调节发电机输入机械功率,输出的有功功率有增加的趋势,若负载大小不变,转速和频率都将增大(而不是转速不变),若转速和频率不变,则输出的有功功率将增大;调节发电机的励磁电压,发电机的端电压具有升高的趋势,可使同步发电机输出电流的相位具有超前的性质,因此其输出的无功功率就会发生变化。因此有“有功调频,无功调压”之说。 [ ]查看更多 1个回答 . 3人已关注
