摘要
提出用紫外仪判断电机起晕的判据,一方面解决暗室观察防晕的困难,另一方面更加直观地观察到防晕的形态。通过红外成像,将非线性电阻层表面发热功率,简化成直观的彩色图像,为监测发电机防晕的失效、优化防晕结构提供了一种全新的途径。
A criteria by using ultraviolet detector to determine the corona inception of generator is being proposed.Via ultraviolet detector,corona image can be easily observed in darkroom.Meanwhile,the heating power of nonlinear resistive layer can be simplified into visualized color image via infrared technology.This may serve as a reference for operation monitoring and optimization of anti-corona structures for generators.
