Simulation Study on the Factors Influencing Oscillating Switching Impulse Test for Transformers
摘要
Abstract
Oscillating switching impulse (OSI) test for transformers has the advantages in high efficiency,easy wave modulationng wave and smallerdecreasing the size of equipment.In order tTo explore the factors that affect OSI test for transformers,in this studypaper,build a simulation model of OSI test for transformers,is built and takes a 110 kV transformer for example to investigate the effects ofused in study on how the on-resistor of ball gap switch and excitation inductance saturation affect on the test voltage on a 110 kV transformer waveform on high-voltage side.The results show that the on-resistor of ball gap switch will shorten tail time (T,) of OSI waveform,and excitation inductance saturation won't will not affect OSI waveform.These results may conclusion in this paper can offer a referencetheory advice tofor OSI test for transformers.关键词
