Abstract
Life styles based on mass consumption and mass abandonment, which have been made possible by mass production, need to be rethought from the viewpoints of global environmental problems and future shortages of fossil energy resources. For power equiment and power systems, the life extension of power equipment using various diagnosis techniques is an important subject. The larger in size systems become, the more serious the damage to them becomes. Therefore, more sophisticated diagnosis technologies are required. In this paper, an estimation method of vibrations and forces inside gas insulated switchgear, which are caused by an abnormal condition was discussed. The values and locations of inside forces were estimated by solving an inverse problem of the vibrations using calculations and experiments. In the calculations, up to 50 force locations were well estimated. In experiments, up to 6 force locations were well estimated. New method which can estimate the location of inside forces precisely are proposed.
