Abstract

The invention discloses a pre-tension damping suspension vibration reduction device for a converter valve tower. The pre-tension damping suspension vibration reduction device for the converter valve tower comprises suspension insulators, tension insulators and spring dampers; the top of the converter valve tower is obliquely suspended on a valve hall steel roof truss through the multiple suspension insulators, and the resultant force center of the multiple suspension insulators coincides with the center of the converter valve tower; the bottom of the converter valve tower is tied to the groundthrough the multiple tension insulators, and the resultant force center of the multiple tension insulators coincides with the center of the converter valve tower; and one part of the spring dampers are arranged at the suspension positions of the suspension insulators, and the other part of the spring dampers are arranged at the tying positions of the tension insulators. The pre-tension damping suspension vibration reduction device is simple in structure and easy to install, can effectively control the vibration of the converter valve tower under the action of earthquakes to ensure the normalelectrical functions of equipment, occupies a small area to ensure the passing of maintenance vehicles below, and is especially suitable for extra-high-voltage converter valve towers in high seismic-intensity areas.

Description

technical field [0001] The invention relates to the technical field of converter equipment, in particular to a pre-tension damping suspension vibration reduction device which is used for an ultra-high pressure converter valve tower and can effectively reduce the vibration acceleration and horizontal displacement of the valve tower under an earthquake. Background technique [0002] As an important part of a large and complex lifeline system, the power system will directly lead to the paralysis of the entire society once it is damaged in a strong earthquake. Power equipment has been severely damaged in earthquakes over the years, and the seismic performance of power equipment is directly related to the safe operation of the power system, which requires key research. On the one hand, the converter valve tower is one of the most important equipment in the HVDC transmission system, and the seismic performance of the converter valve determines whether the transmission system can o...
