In the present embodiment, damping assembly 3 is fixedly mounted between First Transition structure 1 and the second transition structure 2.Vibration damping
Component 3 is made of at least one damper 31.According to different vibration damping targets, damping assembly 3 can choose different dampers 31,
Meanwhile the number and installation site of damper 31 can also be with flexible configurations.Damper 31 can be spring cushion, be also possible to
Other types of damper.In the present embodiment, damper peace is provided on the damping assembly mounting surface of First Transition structure 1
Attaching mouth；Damper installation interface is provided on the damping assembly mounting surface of the second transition structure 2.1 He of First Transition structure
In second transition structure 2 damper installation interface position correspond to each other, damper install interface quantity be it is multiple, pass through
These dampers install interface, can flexibly be selected damper installation interface come mounting dampers 31 according to vibration damping demand, together
When, but also the handling of damper are more convenient.The type of damper installation interface can be one or more, be subtracted using a variety of
When the device that shakes installs interface, the range of choice of damper is bigger.Certainly, the thing for needing to illustrate, damper installation interface can be pre-
First it is arranged in First Transition structure 1 and the second transition structure 2, is also possible in the class for determining damper according to vibration damping target
After type, quantity and installation site, processed again in First Transition structure 1 and the second transition structure 2.
In the present embodiment, as shown in figure 3, according to vibration damping target, using 2 kinds of dampers of different-stiffness parameter,
Middle front end long side installs I type damper 7, and rear end sides respectively install II type damper 2.Certainly, it should be noted that at this
In embodiment, it is merely illustrative the mounting means of damper 31, the mounting means without therefore limiting damper 31, according to
Different target devices can choose the mounting means of different dampers 31,
In the present embodiment, the first natural frequency of First Transition structure 1 is greater than N times of vibration damping target frequency；Second
The first natural frequency of transition structure 2 is greater than M times of vibration damping target frequency.Intrinsic frequency of the damper 31 in target vibration damping direction
Rate is less than K times of target excitation frequency.In the present embodiment, the value of N is 1.4；The value of M is 1.4；The value of K is 0.4.

L times of side length.The value of L is 0.05.
Vibration absorber through the invention does not need to connect the installation of the installation interface and car body 5 of converter cabinet 4
Mouth is modified, it is only necessary to according to identified vibration damping target selection damper 31 appropriate, and be installed to First Transition structure 1
And second between transition structure 2, and the vibration absorber for meeting vibration damping target can be obtained.Current transformer is realized by the vibration absorber again
It is installed between cabinet body 4 and car body 5, the vibration damping installation to converter cabinet 4 can be realized.When by actual motion discovery there is still a need for
When advanced optimizing vibration damping scheme, what also be can be convenient realizes the optimization of vibration damping scheme by replacement damper 31.With use
It is easy for installation, configuration flexibly, good damping result, it is at low cost the advantages that.
Above-mentioned only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form.Although of the invention
It has been disclosed in a preferred embodiment above, however, it is not intended to limit the invention.Therefore, all without departing from technical solution of the present invention
Content, technical spirit any simple modifications, equivalents, and modifications made to the above embodiment, should all fall according to the present invention
In the range of technical solution of the present invention protection.
