Özet (Çeviri)

ABSTRACTOperation Principles of transformers are based on Faraday?s Law. A powertransformer consists of magnetic circuit, windings, insulators, cooling panels,ventilators and has a very complex structure. Active electric charges producemagnetic field which is a vectoral size. The only reason of magnetic phenomenon isthe charges. Magnetic field is a vectoral field. To make flux travel easier, we use amagnetic circuit which is made of magnetic material. One of the Basic size ofelectric machine is flux and the most researches are generally based on it.Most of the fluxes called leakage fluxes which are the one changes its way afterlinking with a winding are very weak because they follow a very long magneticallyhigh resisted way out of magnetic circuit. Leakage flux produces separately inprimary and secondary windings separately and induces at the winding where it goes.Therefore, there are two types of leakage flux. The one is the primary leakage fluxpresented by formula N1 I 1 and the other is the secondary leakage flux1 1Φ =Θσpresented by formula N2I2 .22Φ =ΘσThe aims of this study are to show the leakage flux distribution by measuring theleakage flux value of shell type transformers with measuring coils and also obtainingflux distribution by using finite element (FEM) and finite difference method (FDM)and to determine the method which gives the closest value to measure values bycomparing these results that based on references.In this thesis, an introduction to leakage flux has been done by giving informationabout magnetic field, the target of this thesis have been put forward and studies toachieve these aims have been expressed in chapter I. Basic subjects related tomagnetic field and researches about this subject have been studied. FEM and FDMhave been shortly explained and in chapter III Turkish and foreign journals aboutthese subjects have been introduced.First, transformer for the experiment and measuring coils which will be used tomeasure leakage flux have been prepared. In chapter IV, studies related to thissubject have been explained. In chapter V, results of measurements from have beengiven experiments. In chapter VI, mathematical applications of these methods hadbeen done. 1521 by 1521 matrix has been solved to calculate the leakage flux valueby using these methods and analysis has been done. Then by using Ms Excel Spreadpolonium equation has been formed and by using this equation flux values havebeen calculated. In the chapter VII, according to the experimental results andcalculated values by FEM and FDM leakage flux distributions have been given. Bycomparison done it has been figured out that calculations done by FEM give theclosest result to the one obtained by measurements out of other methods.In the chapter VIII, suggestions have been put forth for consideration in the light ofgathered results. By comparing with reference to the measured values, It has beenhandled that the results obtained by FEM are more closer to the measured valuesthan the other. By making measurements with the leakage flux sensors in a specificpoints in order to obtain the leakage flux distribution for high power transformers,leakage flux distribution belonging to that transformer could be found close to realvalues with the FEM.May 2005 øVPDLO%2=.857
