发电机定子绕组端部振动静态特性的试验研究

对发电机定子绕组端部振动静态特性进行了试验研究,提出了发电机定子绕组鼻端头部自振静频率落入100H。共振的危险性取决于其振幅的大小,给出了间接判断发电杌定子绕组鼻端头部静频率振幅大小的方法;分析了当发电杌定子绕组端部椭圆形振动落入100Hz附近时,应根据发电杌的历史状况来决定其处理的方法．

Testing and Study on the Static Characteristics of End Part Vibration of Generator's Stator Winding

The testing and study on the static characteristics of end part vibration of generator's stator winding were carried out,it was proposed that the danger of "self-vibration static frequency of nose tip part of generator's stator winding falling into 100 Hz resonance" depended on the magnitude of its vibration amplitude,the method for determining the static frequency vibration amplitude magnitude of nose tip part of generator's stator winding was given;when the elliptic vibration of end part of generator's stator winding fell into the vicinity of 100 Hz,the handling method should be determined according to the historical condition of generator.
