本文阐述了新型的光纤仪表在大型水轮发电机气隙特性的精密动态测量和分析中的应用及其发展,该系统使用一个被动式光纤传感器、该传感器不受电磁脉冲的干拢,因而可在有激磁的发电机中工作。气隙试验是在4台容量为184MVA、定子内径为15.6m的发电机上进行的,发电机定子由16个放射布置的定子支架支持,试验机组之一是B、C水电站1号机组,该机在1979年试运转期间由于定子转子相碰而损坏。试验中,在电机连续旋转时,对作了标记的支持棒上的精确重复点以及中间点进行了32个气隙数据的测量,本文对试验情况及数据作了分析说明。
This article describes the application and development of a new type of optical fiber instrument in the precise dynamic measurement and analysis of the air gap characteristics of a large hydroelectric generator using a passive optical fiber sensor that is immune to the electromagnetic pulse so that There is excitation in the generator work. The air gap test is carried out on four generators with a capacity of 184 MVA and a stator inner diameter of 15.6 m. The generator stator is supported by 16 radially arranged stator supports. One of the test units is Unit 1 and Unit B, During trial run in 1979, the stator rotor was damaged. In the test, 32 air gap data were measured at the exact repetition points and the midpoint of the marked support rods as the motor continued to rotate. The experimental results and data were analyzed and explained.
