摘要
Abstract
The stray current of rail transit in operation may invade the neutral point of the line and the traction sub-station,causing the DC bias operation of the transformer,resulting in the increase of vibration and noise as well as fault probability of transformer.For studying the characteristics of the influence of urban rail transit on the vibration and noise of transformers,the vibration spectrum characteristics of the transformer during DC bias operation is theo-retically analyzed.Then,a method for the simultaneous measurement of electricity and non-electricity is introduced to measure simultaneously such physical quantities as neutral point current,vibration and noise of transformer of 220 kV substation in Guangzhou North District and study the relationship between rail transit operation and substa-tion vibration and noise.Finally,the data normalization method is used to obtain the general law of 220 kV transform-er vibration noise in Guangzhou North District affected by rail transit operation.关键词
