Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and a detailed implementation mode and specific operation process are given.

[0040] The damping shock isolation device proposed by this application mainly includes the following components:

[0041] (1) The metal plate connected to the flange of the root of the wall bushing;

[0042] (2) A number of friction dampers that need to be rationally optimized for anti-seismic root;

[0043] (3) The crossbeam protruding rod used to provide the connection point when the valve hall is connected to the damper.

[0044] As an embodiment, a damping device for connecting the wall bushing and the valve hall is characterized in that the device can effectively reduce the seismic response of the wall bushing;

[0045] Including wall bushing 1, root flange 2, me...

Abstract

The invention relates to a damping device for vibration control of a wall bushing. The damping device can effectively reduce the seismic response of the wall bushing. The arrangement height of the damping device in a valve hall is determined according to requirements, an upper chord, a lower chord and a web member are arranged on a steel frame according to the height, groove-shaped connecting pieces are welded in the direction perpendicular to rod pieces, the wall bushing is connected with a metal plate at the periphery of a root flange, one end of a barrel-type friction damper is connected with the groove-shaped connecting piece, and the other end of the barrel-type friction damper is connected with the periphery of the metal plate; and dampers are arranged on different planes and in different directions to form a damping connecting device with enough rigidity constraint. Compared with the prior art, the damping device is simple in structure and easy to install, does not influence theelectrical function requirements of power transformation equipment, and can effectively weaken the seismic response of the wall bushing.

Description

technical field [0001] The invention relates to the technical field of wall-piercing bushing equipment, in particular to a damping connection device for vibration control of wall-piercing bushings. Background technique [0002] With the development of high-voltage direct current transmission technology, direct current transmission has played a huge role in the composition of China's power grid, especially in the "west-to-east power transmission". As a power source, the southwest region is in an earthquake-prone zone, and the safety of related power equipment under earthquakes needs to be paid attention to. The power system has shown extremely high vulnerability in previous earthquakes. In 1994, the power system damage caused by Northridge in the United States was mainly concentrated in 230kV and 550kV substations. The earthquake also caused 1.1 million people in North America to lose electricity Interruption; In the Kobe earthquake in Japan in 1995, the damage to the porcel...
