Annotation: The problem of reducing the level of vibrations of rigid busbar structures in many cases is associated with the need to increase rigidity and reduce the material consumption of structures, however, it is important to fulfill the technological requirements of the operating conditions and protect people from the harmful effects of vibrations. The article discusses new ways of damping vibrations of rigid busbar structures under the action of the vortex excitation of the wind – «damper on the thread», damper in the form of a rigid insert, spring damper. Mathematical models of joint operation of rigid busbar design with damping devices are given. It has been given theoretical studies of the joint design of rigid busbars with damping devices. New recommendations have been developed that allow the selection of a rational type of damping device and the calculation of the main parameters of an oscillation damper of rigid busbar structures, as well as the conditions for its adjustment and operation.
Keywords: rigid busbar, pipe-tire, open distribution devices, vibration damper, damping, wind resonance, vortex excitation of vibrations.
