AC contactor is a kind of low-voltage electrical apparatus which applied widely. The bounce of the contact in the closing process is one of the important factors which will affect the system performance and its electrical endurance. The closing process of AC contactor is a nonlinear and complex dynamic process. If the input energy is more than the expending energy which caused by coil and the others,...
This paper presents a comparison of the resistance performance of Au-Au micro-contacts fabricated with planar and engineered lower contacts. Gray-scale lithography was used to construct 3D structures into photoresist. The structures were then etched into a silicon wafer using a Trion reactive ion etch (RIE) system. The engineered lower contact surfaces consisted of 2D pyramids and 3D pyramid patterns...
Surface structure plays a fundamental role for understanding the performance of sliding contacts. In this study surface structures were analyzed by confocal microscopy with special emphasis to anisotropic structure components. Such components can exist as part of the original surface structure and/or arise during sliding. For this purpose FFT analysis and autocorrelation analysis is being used for...
