The calculation and application of oil-paper insulation system equivalent circuit parameters
摘要
Abstract
Transformer oil - paper insulation system can be equivalent to the extended debye circuit model, changed the equivalent circuit model into a mathematical model and derived recovery voltage e-quation in detail. Put forward the method of use the recovery voltage maximum and the peak time of the voltage characteristic calculate equivalent circuit parameters, and calculated the equivalent circuit parameters of four different operating years transformers by recovery voltage characteristics which had been measured before, verified the accuracy of the parameters, substituted the parameters into the e-quivalent circuit model and emulated, obtained the polarization current curves, further analysis the relationship between the transformer oil - paper insulation condition and the equivalent circuit parameters.关键词
