Features of application of rigid bus designs in outdoor switchgears
Abstract: The paper deals with the domestic and foreign experience of rigid bus design application in outdoor switchgears. There have been various variants of rigid bus design, including the big spans. The principle emphasis in the design analysis has been done to the ways of vibration termination of rigid bus designs at vortex excitation of vibrations under the wind effect. The familiar ways of vibration damping of the rigid bus designs have been analysed. The main principles of work of special-purpose vibration damping devices – dampers used in this kind of designs have been considered. The latest designs and offers of the problems proposed by the Russian and Ukrainian researchers have been also presented in the paper. The disadvantages of the existing methods of vibration termination have been pointed out and the conclusions of the prospect trends of research and investigations in the sphere of generation and invention of fresh methods of vibration termination in the rigid bus designs have been formulated.
Keywords: rigid bus, tube-busbar, outdoor switchgear, damper, damping, wind resonance, vortex vibration excitation.
