Abstract

The invention discloses a suspension insulator connecting device for improving the anti-seismic property of a converter valve tower. The device is mounted at the joint of a suspension insulator of theconverter valve tower and a valve hall roof truss, and comprises a spherical hinge screw rod, a ball head, a spherical hinge base, a spherical hinge bottom plate, a sleeve, a connecting rod, and upper and lower springs in the sleeve; a spherical hinge is connected with a valve hall steel hanger; the sleeve is fixed to the spherical hinge base through the spherical hinge bottom plate; the connecting rod penetrates through the sleeve; the springs are arranged on the upper and lower sides of the portion, located in the sleeve, of the connecting rod; and a connector with a reserved bolt hole is arranged at the bottom of the lower-section rod of the connecting rod and connected with the valve tower suspension insulator through a bolt. The device can effectively control the vibration of the converter valve tower under the action of an earthquake, avoids the elastic rebound phenomenon of the converter valve tower, and has the characteristics of simple structure, easiness in installation, lowmanufacturing cost, no influence on the normal electrical function of equipment and no occupation of a ground area.

Description

technical field

[0001] The invention relates to the technical field of converter station equipment, in particular to a suspension insulator connection device for improving the seismic performance of a converter valve tower 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. As the core equipment in the DC transmission project, the seismic performance of the valve hall and valve tower structure of the converter station is the key to ensure the safe and reliable operation of the DC transmission system.

[0003] On the one hand, the converter valve tower is one of the most important equipment in the HVDC transmissi...
