Description
Summary:碩士 === 國立臺灣科技大學 === 電機工程系 === 93 === In this thesis, it is to study the effects of space arrangement of power cables on the distribution of the magnetic field and the reduction methods. At first, the Biot Savart’s law is applied to get the distribution formula of magnetic field according to the arrangement. It is found that if cables are concentrated in suitable arrangement, the magnetic field produced by the three-phase current source can be cancelled themselves. Then it is to investigate the effect of shielding materials when the characteristics of magnetic filed caused by cable arrangement are considered. From the study results, proper cable arrangement should greatly reduce magnetic field. The shielding metal sheets would have different effects according to the characteristics of magnetic field. It is required to study and select suitable shielding materials before they are used to reduce magnetic field.
