Damping spring device

Abstract

The invention discloses a damping spring device which comprises an upper-end pull lug, a flange plate, a steel shaft sleeve, a disc spring, an upper end plate, an orienteering shaft and a lower end plate. An edge is formed at the top end of the steel shaft sleeve outwards in the radial direction. The flange plate is arranged at the top end of the steel shaft sleeve and is fixed with the edge of the steel shaft sleeve. The upper-end pull lug is fixed to the outer side of the flange plate. The upper end plate is arranged on the inner wall of the top end of the steel shaft sleeve and is fixed with the inner side of the flange plate. The lower end plate is fixed to the bottom end of the steel shaft sleeve. The orientating shaft is fixed to the side, facing the lower end plate, of the upper endplate. The part, extending out of the lower end plate, of the orientating shaft serves as a lower-end pull lug. The disc spring is mounted between the upper end plate and the lower end plate with theorientating shaft as the center and is stacked along the inner wall of the steel shaft sleeve. By means of the device, stimulation of a vibration source to a platform can be relieved through deformation of components, the overall damping performance of the platform can be improved, and the safety coefficient of the platform under dynamic loads can be increased.

Description

technical field [0001] The invention relates to a support system for a large-scale equipment installation platform in a high-voltage power transmission system, in particular to a device capable of increasing the safety factor of the platform under dynamic load. Background technique [0002] In the power system, in order to improve the transmission capacity of the system, the technology of connecting capacitor banks in series in the line, changing the line parameters and reducing the line impedance is adopted. Since the capacitor bank is connected in series in the line, in order to meet the requirements of high-voltage insulation, the capacitor bank needs to be installed on a steel structure platform, and the platform also needs to carry a certain capacity of metal oxide arresters, spark gaps, damping resistors, damping reactors, etc. Other primary equipment with large volume and heavy weight. The steel structure platform together with post insulators, cable-stayed insulator...

AI Technical Summary

Problems solved by technology

However, as the voltage level increases, the height of the structural system will increase, and the load it will bear will also increase significantly.

On the other hand, due to the realization of the electrical performance of the power transmission equipment, there are strict restrictions on the horizontal deformation of the structural system

At the same time, due to the constraints of structural materials, a single composite cable-stayed insulator cannot meet the requirements of the structural system at high voltage levels
